Abstract

The determination of open-pit reasonable trenching position has important influence to open-pit mine production continue and stripping control. The essay applicate the basic decision theory of analytic hierarchy, construct hierarchical analysis model of comprehensive evaluation of open-pit mine trenching position scheme, combined with the coal storage and present situation of mining in Inner Mongolia Baorixile open-pit mine, explain the feasibility and the necessity of the coal mine ditch in the mined out area of three mining the upper coal seam and exploit the lower coal seam. According to the choosing principle of open- pit trenching position and the mine special geological and topographic conditions, design two trenching position optimization, and analyzes the influence of various factors on the lower coal seam trenching position selection. Using the analytic hierarchy process, analysis of the advantages and disadvantages of each scheme comparison, eventually determine the most reasonable trenching position scheme. The result shows that: the evaluation result of analytic hierarchy process accords the actual situation, simple calculation, and has stronger practicability.
