| 1 | Time range of Mesozoic tectonic regime inversion in eastern North China Block显示文摘An important tectonic inversion took place in eastern North China Block(NCB) during Mesozoic, which caused a great lithosphere thinning, reconstruction of basin-range series, powerful interaction between mantle and crust, a vast granitic intrusion and volcanism, and large-scale metallogenic explosion. The time range of the Mesozoic tectonic regime inversion in the eastern North China Block is one of the key issues to understand mechanism of tectonic regime inversion. Our updated results for recognizing the time range are mainly obtained from the following aspects: structural analyses along northern and southern margins of the NCB and within the NCB for revealing tectonic inversion from compression to extension and structural striking from ~EW to NNE; geothermic analyses of the eastern sedimental basins for a great change of thermal history and regime; basin analysis for basin inversion from compression to extension and basin migration from ~EW to NNE; petrological and geochemical studies of volcanic rocks and lowermost crust xenoliths for recognizing peak period of mantle upwelling and intense interaction between mantle and crust, and main metallogenic epoch. All the studies of the above give the same time range from~150-140 Ma to ~110-100Ma, peaking at ~120 Ma. | ZHAI Mingguo ZHU Rixiang LIU Jianming MENG Qingren HOU Quanlin HU Shengbiao LIU Wei LI Zhong ZHANG Hongfu ZHANG Huafeng | 2004 | Science China Earth Sciences2004,47,2: | 89 |

| 4 | Predictive value of the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score in the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure显示文摘Background:As a large,prospective,multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure(HBV-ACLF),the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score(COSSH-ACLFs),has been approved by some foreign scholars;however,its predictive value needs to be verified.This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF.Methods:This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014.Spearman method was used to assess the correlation of COSSHACLFs with classical scores.Different COX multivariate regression models were used to confirm the relationship between COSSHACLFs and short-term prognosis in patients with HBV-ACLF,and stratified analysis was used to further verify the stability of this relationship.We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve(AUROC)and Z-test.Results:A total of 975 patients with HBV-ACLF were screened,and 751 were analyzed(623 male and 128 female).COSSH-ACLFs was the highest in patients with end-stage ACLF,followed by those with middle-and early-stage ACLF(H=211.8,P<0.001).In the fully adjusted model,COX multivariate regression analysis revealed that COSSH-ACLFs(as a continuous variable)was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days(hazard ratio[HR]:1.37[1.22,1.53],P<0.001)and 90 days(HR:1.43[1.29,1.58],P<0.001).The same trend could be observed in the crude model and minimally adjusted model.The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792,respectively,indicating a stronger predictive accuracy than those of classic models.Conclusions:COSSH-ACLFs,with a superior predictive accuracy compared with other classical scores,can strongly predict shortterm prognosis in Chinese patients with HBV-ACLF. | Jing-Jing Tong Wei Zhao Xiu-Ying Mu Xiang Xu Hai-Bin Su Xiao-Yan Liu Jing Chen Xing-Ran Zhai Yu Wang Jin-Hua Hu | 2019 | Chinese Medical Journal2019,,13: | 27 |
| 5 | Safety threshold of high-speed railway pier settlement based on train-track-bridge dynamic interaction显示文摘This paper presents a method to determine the safety threshold of bridge pier settlement in high-speed railways.An analytical expression of the mapping relationship between the pier settlement and the rail deformation is derived theoretically for the double block ballastless track-bridge system.By adopting the superposition of the track random irregularity and the rail deformation caused by the pier settlement as the excitation inputs,the variations of vehicle dynamics indices with pier settlement are comparatively analyzed.Then,the safety threshold of the bridge pier settlement is obtained according to the limit of vehicle running safety and ride comfort indices of the high-speed trains.Results show that the dynamics indices of different trains have different sensitivities to the pier settlement,and the train CRH2C is the most sensitive one among all the types of Chinese high-speed trains.When passing through the bridges in common span with pier settlement at the speed of 250–350 km/h,the trains suffer the low-frequency excitations,and the vertical acceleration of car body is most sensitive to the pier settlement of all the dynamics indices.When the car body vertical acceleration just exceeds the allowable limit,the critical settlement value is 23.4 mm,which is much bigger than the pier differential settlement limit in the current code for Chinese high-speed railways. | CHEN Zhao Wei ZHAI Wan Ming CAI Cheng Biao SUN Yu | 2015 | Science China(Technological Sciences)2015,58,2: | 26 |
| 6 | Perinatal complications and live-birth outcomes following assisted reproductive technology: a retrospective cohort study显示文摘Background:With the development of assisted reproductive technology(ART)and its increasing success rate in the mainland of China,more attention has been paid to the safety of ART.In this study,we explored the associations between conception by ART and pregnancy/perinatal complications,and neonatal outcomes compared with similar outcomes following spontaneous conception.Methods:This retrospective cohort study of pregnancies over a 3-year period(2013-2015)was performed at Beijing Obstetrics and Gynecology Hospital,Beijing,China.Subjects were divided into two groups:conception by ART(n=2256)or spontaneous conception(n=6768).According to different fertilization modes,the ART group was divided into in vitro fertilization(IVF,n=1873)and intracytoplasmic sperm injection(ICSI,n=383)subgroups.The ART group was also divided into two different embryo transfer methods;fresh embryo transfer(ET,n=1583)and frozen embryo transfer(FET,n=673)subgroups.Pregnancy complications,perinatal complications,and neonatal outcomes of the enrolled subjects were investigated and analyzed by univariate analysis and multivariate logistic regression.Results:After adjustment for maternal age,gravidity,parity,maternal education,smoking,alcohol consumption,and body mass index(BMI),pregnancies conceived by ART were associated with a significantly increased incidence of gestational diabetes mellitus(GDM;OR 1.88,95%CI 1.56-2.27),gestational hypertension(OR 2.18,95%CI 1.83-2.60),and intrahepatic cholestasis of pregnancy(ICP)(OR 2.79,95%CI 2.15-3.64),compared with spontaneous conception.These associations were similar for the singleton group.In the twin group,only the incidence of ICP was significantly higher than in controls.We found that pregnancies conceived by ART were associated with perinatal complications,including placental abruption(OR 2.14,95%CI 1.33-3.45),premature rupture of membranes(PROM;OR 1.24,95%CI 1.06-1.45),postpartum hemorrhage(OR 2.89,95%CI 2.33-3.59)and polyhydramnios(OR 2.01,95%CI 1.29-3.16).The singleton group had a similar result with placental abruption,but not with fetal membranes ruptures before labor and polyhydramnios.There were no significant differences in the incidence of these perinatal complications in the twin group.Some neonatal outcomes,including preterm labor(OR 4.29,95%CI 3.84-4.80)and low birth weight(OR 1.72,95%CI 1.42-2.08),were more likely to occur with singleton births after ART.However,there were no significant differences for these outcomes from twin pregnancies.Perinatal complications and neonatal outcomes were consistent between the IVF and ICSI subgroups.The FET and ET subgroups showed a similar increase in complications,except for the incidence of placental abruption.After taking into account the effects of parity,birth plurality and maternal age,the ART group still exhibited increased maternal and neonatal complications,although some differences narrowed or disappeared.Conclusions:This retrospective cohort study demonstrated that patients who underwent ART were at increased risk of several adverse pregnancy outcomes compared with women who conceived spontaneously.These complications may be attributed in part to the relatively high multiple pregnancy rate after ART.Elective single embryo transfer should be promoted in China to reduce the obstetrical risks of ART pregnancy.Singletons of ART pregnancy exhibited increased maternal and neonatal complications as well,suggesting that underlying infertility or other maternal or parental factors may contribute to the adverse outcomes. | Ling-Ling Lei Yong-Lian Lan Shu-Yu Wang Wei Feng Zhi-Jin Zhai | 2019 | Chinese Medical Journal2019,,20: | 24 |

| 8 | Dental stem cell and dental tissue regeneration显示文摘The teeth are highly differentiated chewing organs formed by the development of tooth germ tissue located in the jaw and consist of the enamel, dentin, cementum, pulp, and periodontal tissue. Moreover, the teeth have a complicated regulatory mechanism, special histologic origin, diverse structure, and important function in mastication, articulation, and aesthetics. These characteristics, to a certain extent, greatly complicate the research in tooth regeneration. Recently, new ideas for tooth and tissue regeneration have begun to appear with rapid developments in the theories and technologies in tissue engineering. Numerous types of stem cells have been isolated from dental tissue, such as dental pulp stem cells (DPSCs), stem cells isolated from human pulp of exfoliated deciduous teeth (SHED), periodontal ligament stem cells (PDLSCs), stem cells from apical papilla (SCAPs), and dental follicle cells (DFCs). All these cells can regenerate the tissue of tooth. This review outlines the cell types and strategies of stem cell therapy applied in tooth regeneration, in order to provide theoretical basis for clinical treatments. | Qiming Zhai Zhiwei Dong Wei Wang Bei Li Yan Jin | 2019 | Frontiers of Medicine2019,13,2: | 23 |
| 9 | Polyphenolic Compound and the Degree of Browning in Processing Apple Varieties显示文摘Polyphenolic compound in processing apple (Malus domestica Borkh.) varieties and the relationship between polyphenol content and enzymatic browning were studied to provide reference for raw material selection and processing method optimization. The content of polyphenol compound in 10 processing apple varieties (4 cider and 6 juice varieties) were analyzed using the Folin-Ciocalteu method and HPLC. The degree of browning and the activities of polyphenol oxidase were also studied. The content and proportion of the polyphenol varied depending on the variety. Bitter varieties globally showed a higher polyphenol concentration than sweet or acid varieties. Proanthocyanidins, chlorogenic acid, (+)-catechin, (-)-epicatechin were high-concentrated polyphenols in apple fruits. Phloridzin, the unique polyphenol of apple, was abundant in the bitter variety Frequin rouge fruit. Total polyphenols, proanthocyanidins, (+)-catechin, and phloridzin had higher correlations with browning. The correlation was low between chlorogenic acid and browning. The polyphenolic profiles were correlated with the apple types. Cider apples contained more polyphenol than juice apple varieties. The content of flavan-3-ol has a close relationship with fruit browning. | SONG Ye YAO Yu-xin ZHAI Heng DU Yuan-peng CHEN Feng WEI Shu-wei | 2007 | Agricultural Sciences in China2007,6,5: | 17 |
| 10 | Magnetic resonance imaging for local complications of acute pancreatitis: A pictorial review显示文摘Acute pancreatitis is a common disease characterized by sudden upper abdominal pain and vomiting. Alcoholism and choledocholithiasis are the most common factors for this disease. The choice of treatment for acute pancreatitis might be affected by local complications, such as local hemorrhage in or around the pancreas, and peripancreatic infection or pseudoaneurysm. Diagnostic imaging modalities for acute pancreatitis have a significant role in confirming the diagnosis of the disease, helping detect the extent of pancreatic necrosis, and for diagnosing local complications. Magnetic resonance imaging (MRI) might be indicated in acute pancreatitis for detecting and characterizing local complications of acute pancreatitis that involve necrotic, hemorrhagic, infectious, vascular, and pseudocyst disorders. The general MRI sequences for pancreatitis require the combined use of T1-weighted, T2-weighted sequences, and magnetic resonance chol-angiopancreatography. For imaging of pancreatic necrosis, the combination of T1-weighted and T2-weighted findings with dynamic contrast-enhanced imaging gives a comprehensive evaluation of the extent of necrosis and full range of inflammatory extension. For imaging of infectious complications, dynamic contrast-enhanced examinations might help differentiate pancreatic cellulitis or abscesses, from pancreatic fluid collection or simple pseudocysts. For vascular abnormalities, the combination of cross-sectional pancreatic parenchyma imaging with MRA represents a single diagnostic modality for the full evaluation of peripancreatic artery and vein involvement, such as arterial pseudoaneurysms and venous thromboses. The purpose of this pictorial review is to examine the MRI appearances of various local complications of acute pancreatitis and to discuss the practical setup of MRI in local complications of acute pancreatitis. | Xiao, Bo Zhang, Xiao-Ming Tang, Wei Zeng, Nan-Lin Zhai, Zhao-Hua | 2010 | World Journal of Gastroenterology2010,16,22: | 17 |
| 11 | He-Ar isotope geochemistry of the Yaoling-Meiziwo tungsten deposit,North Guangdong Province:Constraints on Yanshanian crust-mantle interaction and metallogenesis in SE China显示文摘Isotopic abundances and ratios of He and Ar found in inclusion fluids in pyrites formed in the Yaoling-Meiziwo tungsten miner-alization epoch show that the concentration of 4He varies widely,from 1.54×10-7 cm3 STP/g to 2609×10-7 cm3 STP/g.3He is 0.759×10-12 cm3 STP/g-3.463×10-12 cm3 STP/g.3He/4He is 0.0043-4.362 Ra,varying from crustal to mantle values.The concen-tration of 40Ar ranges from 0.624×10-7 cm3 STP/g to 8.89×10-7 cm3 STP/g.The 40Ar/36Ar varies extensively,from 330 to 2952,between atmospheric and crustal or mantle radiogenic values.Mantle-derived He is present in ore-forming fluids and the calcu-lated average proportion of the mantle He is 22%;the maximum is 67%.Our research results show that mantle-derived fluids play a significant role in tungsten mineralization.The fractionation of He and Ar indicate that there was 4He-enriched air-saturated water(MSAW) in the ore-forming fluid.The ore-forming fluid was a mixture of mantle fluid,crustal magmatic fluid and MSAW.The occurrence of a mantle component in ore-forming fluid indicates the large-scale W and Sn mineralization,including Yaol-ing-Meiziwo,in southeastern China was the result of crust and mantle interaction.The underplating or intrusion of voluminous basaltic magma formed by partial melting of the upper mantle provided the necessary heat to cause partial melting of the crust and the generation of voluminous S-type granitic magmas.Crustal magmatic fluid and mantle fluid with high 3He/4He were released from magma crystallization and fractionation,mixed with the circulating modified air-saturated water,and filled the extensional tectonic fractures,leading to the formation of world-class W and Sn deposits in southeastern China. | ZHAI Wei SUN XiaoMing WU YunShan SUN YanYan HUA RenMin YE XianRen | 2012 | Chinese Science Bulletin2012,57,10: | 16 |
| 12 | Emerging in-plane anisotropic two-dimensional materials显示文摘Black phosphorus(BP)is a rapidly up and coming star in two-dimensional(2D)materials.The unique characteristic of BP is its in-plane anisotropy.This characteristic of BP ignites a new type of 2D materials that have low-symmetry structures and in-plane anisotropic properties.On this basis,they offer richer and more unique low-dimensional physics compared to isotropic 2D materials,thus providing a fertile ground for novel applications including electronics,optoelectronics,molecular detection,thermoelectric,piezoelectric,and ferroelectric with respect to in-plane anisotropy.This article reviews the recent advance in characterization and applications of in-plane anisotropic 2D materials. | Liang Li Wei Han Lejing Pi Ping Niu Junbo Han Chengliang Wang Bin Su Huiqiao Li Jie Xiong Yoshio Bando Tianyou Zhai | 2019 | InfoMat2019,1,1: | 16 |
| 13 | Analysis of vibration reduction characteristics and applicability of steel-spring floating-slab track显示文摘A coupled dynamics computation model for metro vehicles,along with a steel-spring floating-slab track,is developed based on the theory of vehicle-track coupled dynamics.Using the developed model,the influences of the thickness,length and mass of floating-slab,spring rate and its arrangement space,running speed,etc.on the time and frequency domain characteristics of steel-spring fulcrum force are analyzed.The applicability of steel-spring floating-slab track is discussed through two integrated example cases of metro and buildings possessing distinct natural vibra-tion characteristics.It is concluded that,it is quite significant,in the optimization modular design of the parameters of steel-spring floating-slab track,to take the matching relationship of both the amplitude-frequency characteristics of steel-spring fulcrum force and natural vibration characteristics of integrated structures into comprehensive considera-tion.In this way the expensive steel-spring floating-slab track can be economically and efficiently utilized according to the site condition,and at the same time,the economic losses and bad social impact resulted from the resonance during usage of steel-spring floating-slab track can be avoided. | Wanming ZHAI Peng XU Kai WEI | 2011 | Journal of Modern Transportation2011,19,4: | 14 |
| 14 | Progress in Global Gas Hydrate Development and Production as a New Energy Resource显示文摘Natural gas hydrates have been hailed as a new and promising unconventional alternative energy,especially as fossil fuels approach depletion,energy consumption soars,and fossil fuel prices rise,owing to their extensive distribution,abundance,and high fuel efficiency.Gas hydrate reservoirs are similar to a storage cupboard in the global carbon cycle,containing most of the world's methane and accounting for a third of Earth's mobile organic carbon.We investigated gas hydrate stability zone burial depths from the viewpoint of conditions associated with stable existence of gas hydrates,such as temperature,pressure,and heat flow,based on related data collected by the global drilling programs.Hydrate-related areas are estimated using various biological,geochemical and geophysical tools.Based on a series of previous investigations,we cover the history and status of gas hydrate exploration in the USA,Japan,South Korea,India,Germany,the polar areas,and China.Then,we review the current techniques for hydrate exploration in a global scale.Additionally,we briefly review existing techniques for recovering methane from gas hydrates,including thermal stimulation,depressurization,chemical injection,and CH4-CO2 exchange,as well as corresponding global field trials in Russia,Japan,United States,Canada and China.In particular,unlike diagenetic gas hydrates in coarse sandy sediments in Japan and gravel sediments in the United States and Canada,most gas hydrates in the northem South China Sea are non-diagenetic and exist in fine-grained sediments with a vein-like morphology.Therefore,especially in terms of the offshore production test in gas hydrate reservoirs in the Shenhu area in the north slope of the South China Sea,Chinese scientists have proposed two unprecedented techniques that have been verified during the field trials:solid fluidization and formation fluid extraction.Herein,we introduce the two production techniques,as well as the so-called'fbur-in-one'environmental monitoring system employed during the Shenhu production test.Methane is not currently commercially produced from gas hydrates anywhere in the world;therefore,the objective of field trials is to prove whether existing techniques could be applied as feasible and economic production methods for gas hydrates in deep-water sediments and permafrost zones.Before achieving commercial methane recovery from gas hydrates,it should be necessary to measure the geologic properties of gas hydrate reservoirs to optimize and improve existing production techniques.Herein,we propose horizontal wells,multilateral wells,and cluster wells improved by the vertical and in dividual wells applied during existing field trials.It is noteworthy that relatively pure gas hydrates occur in seafloor mounds,within near-surface sediments,and in gas migration conduits.Their extensive distribution,high saturation,and easy access mean that these types of gas hydrate may attract considerable attention from academia and industry in the future.Herein,we also review the occurrence and development of concentrated shallow hydrate accumulations and briefly introduce exploration and production techniques.In the closing section,we discuss future research needs,key issues,and major challenges related to gas hydrate exploration and production.We believe this review article provides insight on past,present,and future gas hydrate exploration and production to provide guidelines and stimulate new work into the field of gas hydrates. | LIU Liping SUN Zhilei ZHANG Lei WU Nengyou Yichao Qin JIANG Zuzhou GENG Wei CAO Hong ZHANG Xilin ZHAI Bin XU Cuiling SHEN Zhicong JIA Yonggang | 2019 | Acta Geologica Sinica(English Edition)2019,93,3: | 13 |
| 15 | Guiding-controlling technology of coal seam hydraulic fracturing fractures extension显示文摘Aiming at the uncontrollable problem of extension direction of coal seam hydraulic fracturing,this study analyzed the course of fractures variation around the boreholes in process of hydraulic fracturing,and carried out the numerical simulations to investigate the effect of artificial predetermined fractures on stress distribution around fractured holes.The simulation results show that partial coal mass occurs relatively strong shear failure and forms weak surfaces,and then fractures extended along the desired direction while predetermined fractures changed stress distribution.Directional fracturing makes the fractures link up and the pressure on coal mass is relieved within fractured regions.Combining deep hole controlling blasting with hydraulic fracturing was proposed to realize the extension guiding-controlling technology of coal seam fractures.Industrial experiments prove that this technology can avoid local stress concentration and dramatically widen the pressure relief scope of deep hole controlling blasting.The permeability of fractured coal seam increased significantly,and gas extraction was greatly improved.Besides,regional pressure relief and permeability increase was achieved in this study. | Zhai Cheng Li Min Sun Chen Zhang Jianguo Yang Wei Li Quangui | 2012 | International Journal of Mining Science and Technology2012,22,6: | 12 |
| 16 | Effects of subchronic oral toxic metal exposure on the intestinal microbiota of mice显示文摘Oral exposure to toxic metals such as cadmium(Cd), lead(Pb), copper(Cu) and aluminum(Al) can induce various adverse health effects in humans and animals. However, the effects of these metals on the gut microbiota have received limited attention. The present study demonstrated that long-term toxic metal exposure altered the intestinal microbiota of mice in a metal-specific and time-dependent manner.Subchronic oral Cu exposure for eight weeks caused a profound decline in gut microbial diversity in mice,whereas no significant changes were observed in groups treated with other metals. Cd exposure significantly increased the relative abundances of organisms from the genera Alistipes and Odoribacter and caused marked decreases in Mollicutes and unclassified Ruminococcaceae. Pb exposure significantly decreased the abundances of eight genera: unclassified and uncultured Ruminococcaceae, unclassified Lachnospiraceae, Ruminiclostridium_9, Rikenellaceae_RC9_gut_group, Oscillibacter, Anaerotruncus and Lachnoclostridium. Cu exposure affected abundances of the genera Alistipes, Bacteroides,Ruminococcaceae_UCG-014, Allobaculum, Mollicutes_RF9_norank, Rikenellaceae_RC9_gut_group,Ruminococcaceae_unclassified and Turicibacter. Al exposure increased the abundance of Odoribacter and decreased that of Anaerotruncus. Exposure to any metal for eight weeks significantly decreased the abundance of Akkermansia. These results provide a new understanding regarding the role of toxic metals in the pathogenesis of intestinal and systemic disorders in the host within the gut microbiota framework. | Qixiao Zhai Tianqi Li Leilei Yu Yue Xiao Saisai Feng Jiangping Wu Jianxin Zhao Hao Zhang Wei Chen | 2017 | Science Bulletin2017,62,12: | 12 |

| 18 | Silibinin ameliorates hepatic lipid accumulation and oxidative stress in mice with non-alcoholic steatohepatitis by regulating CFLAR-JNK pathway显示文摘Non-alcoholic steatohepatitis(NASH) is a chronic metabolic syndrome and the CFLAR-JNK pathway can reverse the process of NASH. Although silibinin is used for the treatment of NASH in clinical, its effect on CFLAR-JNK pathway in NASH remains unclear. This study aimed to investigate the effect of silibinin on CFLAR-JNK pathway in NASH models both in vivo and in vitro. The in vivo study was performed using male C57 BL/6 mice fed with methionine– choline-deficient diet and simultaneously treated with silibinin for 6 weeks. The in vitro study was performed by using mouse NCTC-1469 cells which were respectively pretreated with oleic acid plus palmitic acid, and adenovirus-down Cflar for 24 h,then treated with silibinin for 24 h. After the drug treatment, the key indicators involved in CFLAR-JNK pathway including hepatic injury, lipid metabolism and oxidative stress were determined. Silibininsignificantly activated CFLAR and inhibited the phosphorylation of JNK, up-regulated the mRNA expression of Pparα, Fabp5, Cpt1α, Acox, Scd-1, Gpat and Mttp, reduced the activities of serum ALT and AST and the contents of hepatic TG, TC and MDA, increased the expression of NRF2 and the activities of CAT, GSH-Px and HO-1, and decreased the activities and expression of CYP2 E1 and CYP4 A in vivo.These effects were confirmed by the in vitro experiments. Silibinin prevented NASH by regulating CFLAR-JNK pathway, and thereby on one hand promoting the β-oxidation and efflux of fatty acids in liver to relieve lipid accumulation, and on the other hand inducing antioxidase activity(CAT, GSH-Px and HO-1) and inhibiting pro-oxidase activity(CYP2 E1 and CYP4 A) to relieve oxidative stress. | Yayun Liu Wei Xu Ting Zhai Jiaojiao You Yong Chen | 2019 | Acta Pharmaceutica Sinica B2019,9,4: | 12 |

| 20 | A new technology for coal and gas control based on the in situ stress distribution and the roadway layout显示文摘An auxiliary gas control technology is described that can reduce coal and gas outburst accidents when there is no existing protective coal seam and gas pre-draining is not effective.Numerical simulation methods were used to study the stress distribution ahead of the roadway face for different in situ stresses.The results from the simulation can then provide a new gas control technology.The results show that a high stress concentration,high stresses,and high displacement gradients appear ahead of the roadway face when the maximum in situ stress is aligned perpendicular to the roadway axis.The risk of gas outburst is higher when the stresses decrease rapidly over distance and when the release of more energy occurs immediately after driving the roadway.The gas outburst risk is much smaller when the in situ stress is aligned parallel to the roadway axis.During design of the coal mine most of the coal roadways should be arranged to parallel the maximum in situ stress.This will decrease the outburst risk in general and may be considered a new gas outburst prevention method. | Yang Wei Lin Baiquan Zhai Cheng Li Xianzhong Sun Xin Zhang Chao | 2012 | International Journal of Mining Science and Technology2012,22,2: | 11 |
