| 1 | Distribution pattern of front abutment pressure of fully-mechanized working face of soft coal isolated island显示文摘The front abutment pressure of a fully-mechanized workface of 11061 soft coal isolated island of Liangbei Coal Mine was measured and studied using a self-developed mining-induced stress monitoring system associated with electromagnetic radiation technology,and the effects of abutment pressure distribution on strata behavior we discussed.The results indicate that the mining-induced influencing distance advanced at the fully-mechanized working face of soft coal isolated island is larger than that at the general working face at the isolated island,besides the fracture zone in front of working face was widened to some extent,and the influencing range caused by relaxations on both roadways became bigger with the advancing working face.Moreover,it can be indicated that mining has significant effect on strata behavior of fully-mechanized working face of soft coal isolated island,which is mostly distributed in the area of stress concentration.The research results have an important reference value for revealing the distribution pattern of the front abutment pressure of a fully-mechanized working face of soft coal isolated island,and controlling the coal-rock dynamic disaster occurrence under similar mining conditions. | Xu Wenquan Wang Enyua Shen Rongxi Song Dazhao Zhang Jingmin | 2012 | International Journal of Mining Science and Technology2012，22，2： | 16 |
| 2 | Regularity and mechanism of coal resistivity response with different conductive characteristics in complete stress-strain process显示文摘The stress,strain as well as resistivity of coal during uniaxial compression process were tested based on self-built real-time testing system of loaded coal resistivity.Furthermore,the coal resistivity regularity and mechanism were analyzed at different stages of complete stress-strain process,which includes the two kinds of coal body with typical conductive characteristics.The results indicate that coal resistivity with different conductive characteristics has different change rules in complete stress-strain process.It is mainly represented at the densification and flexibility phases before dilatation occurs.The variation of resistivity can be divided into two kinds,named down and up.Dilatation of coal samples occurred between 66%σ_(max) and 87%σ_(max).Because of dilatation,coal resistivity involves sudden change.The overall representation is shifting from reducing into improving or from slow improving into accelerated improving.Thus,coal resistivity always shows an increasing tendency at the plastic stage.After peak stress,coal body enters into failure stage.The expanding and communicating of macro fracture causes further improvement of coal resistivity.The maximum value of resistivity rangeability named λ reached 3.49.Through making real-time monitoring on coal resistivity,variation rules of resistivity can be deemed as precursory information so as to reflect the dilatation and sudden change before coal body reaches buckling failure,which can provide a new technological means for forecasting the dynamic disaster of coal petrography. | Chen Peng Wang Enyuan Chen Xuexi Liu Zhentang Li Zhonghui Shen Rongxi | 2015 | International Journal of Mining Science and Technology2015，25，5： | 3 |

| 7 | Risk factors for post-hepatectomy liver dysfunction in primary liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis显示文摘Objective:The purpose of this study was to analyze risk factors for development of post-hepatectomy liver dysfunction in primary liver cancer(PLC)patients with concurrent hepatic schistosomiasis and chronic hepatitis.Methods:A retrospective analysis of 73 PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis,of which 16 patients developed liver dysfunction(persistent ascites or pleural effusion or occurrence of liver-related potentially fatal complications)following hepatectomy,was performed.After clinical characteristics were recorded,preoperative liver function parameters and surgery-related parameters in these patients were assessed.Seventeen potential risk factors for post-hepatectomy liver dysfunction were identified.The association between these potential risk factors and post-hepatectomy liver dysfunction then was analyzed.Results:Univariate analysis showed that liver cirrhosis,intraoperative blood loss,and preoperative total bilirubin were associated with the development of post-hepatectomy liver dysfunction.Multivariate logistic regression analysis of these three factors revealed that intraoperative blood loss≥600 mL and cirrhosis were two independent risk factors for post-hepatectomy liver dysfunction in PLC patients with concurrent hepatic schistosomiasis and chronic hepatitis.Conclusion:Keeping intraoperative blood loss below 600 mL can help avoid the development of post-hepatectomy liver dysfunction in liver cancer patients with concurrent hepatic schistosomiasis and chronic hepatitis.For patients with concomitant liver cirrhosis,every effort should be made to minimize potential liver function impairment induced by other adverse factors. | ZHANG Minfeng SHEN Weifeng ZHONG Wei LIU Qu SHEN Rongxi YANG Jiamei | 2013 | Journal of Medical Colleges of PLA(China)2013，28，4： | 0 |
