Abstract


Face System is the most important part of the mining activities , it is subject to a variety of factors and directly determines the production capacity of the mine . The purpose of this paper is to establish production system simulation model, and on this basis, combined with the economic analysis to identify reasonable under the given device conditions and economic objectives length of the face , through the control of the input parameters , as well as in the length under production constraints, to study the interplay between the various influencing factors impact on yield and factors at the same time . For this purpose, this article uses the means of simulation , in order to the Large Working Jincheng Coal Industry Group Sihe 2307 as the research object , its optimization study . Other mining face system parameters from the face and mine to start, and the first the 2307 Large Working production system optimization of the mining process . Then through theoretical analysis and simulation , given the important factors that impact the average daily output of the face . The application of mathematical statistical methods to identify sensitive to changes in face length factors . After regression analysis , given the relationship between the sensitivities and face length . In the production system on the basis of this age face inclined length of the simulation test and gives the test results and the yield of the regression formula , and under such conditions is more reasonable range of face length , and the range of economic optimization analysis . Comprehensive optimization analysis by the orthogonal face length , pointed out the direction for the further optimization of the production system .
