| 1 | Selection of overburden surface mining method in West Virginia by analytical hierarchy process显示文摘The broad objective of this research was to improve current surface mining practices and reduce negative environmental impact of overburden removal in West Virginia(WV).The specific objectives were to(i)compare conventional surface mining method(drilling,blasting,digging,and loading)to a surface miner(SM)method,and(ii)apply the analytical hierarchy process(AHP)to help select the optimal mining method based on production,cost and environmental criteria.The design and the procedures used in this research involve five interrelated modules:(i)rock properties of overburden in WV,(ii)drilling and blasting,(iii)digging and loading,(iv)SM method,and(v)comparative analysis and selection of the optimal mining method by AHP.Results of this research indicate that application of SM method would yield higher cost of overburden removal than conventional mining methods in rocks with a high unconfined compressive strength and abrasivity.A significant advantage of SM method,where applicable,is the elimination of the negative environmental impacts associated with blasting. | Timothy A.Nolan Vladislav Kecojevic | 2014 | International Journal of Coal Science & Technology2014，1，3： | 5 |
| 2 | Evaluation of rope shovel operators in surface coal mining using a Multi-Attribute Decision-Making model显示文摘Rope shovels are used to dig and load materials in surface mines. One of the main factors that influence the production rate and energy consumption of rope shovels is the performance of the operator. This paper presents a method for evaluating rope shovel operators using the Multi-Attribute Decision-Making(MADM) model. Data used in this research were collected from an operating surface coal mine in the southern United States. The MADM model consists of attributes, their weights of importance, and alternatives. Shovel operators are considered the alternatives. The energy consumption model was developed with multiple regression analysis, and its variables were included in the MADM model as attributes.Preferences with respect to min/max of the defined attributes were obtained with multi-objective optimization. Multi-objective optimization was conducted with the overall goal of minimizing energy consumption and maximizing production rate. Weights of importance of the attributes were determined by the Analytical Hierarchy Process(AHP). The overall evaluation of operators was performed by one of the MADM models, i.e., PROMETHEE II. The research results presented here may be used by mining professionals to help evaluate the performance of rope shovel operators in surface mining. | Vukotic Ivana Kecojevic Vladislav | 2014 | International Journal of Mining Science and Technology2014，24，2： | 2 |
