针对高瓦斯突出矿井煤层群联合开采的特点,提出了动态编制矿井采掘接替计划的方法.通过对影响矿井采掘工程接替的安全因素和经济因素的分析,建立了影响采掘工程接替的因素指标体系,利用层次分析方法得出了因素的指标权重,采用模糊综合优选法确定备选工作面中的最优接替面,依次类推,直到安排所有的备选工作面.根据采煤工作面生产计划,综合考虑矿井瓦斯治理技术,采用时间反推方法,编制采煤工作面相关的掘进计划.应用研究结果表明,采掘动态接替法可以适时调整采掘接替计划,所得采掘工程接替方案科学合理、切实可行.
Aiming at the characteristics of coal mining in coal seam with high gas outburst in coal mines, a method to dynamically prepare coal mine succession planning is proposed.Through the analysis of the safety factors and economic factors that affect the succession of mine mining engineering, the index system of factors that affect the succession of mining engineering is established, Using AHP to get the index weight of factors, using fuzzy comprehensive optimization method to determine the optimal replacement surface in alternative working surface, and so on until all the alternative working surfaces are arranged.According to the production plan of coal mining face, Mine gas control technology, the use of time backstepping method, the preparation of coal mining face related program.Application results show that mining dynamic takeover method can timely adjust the mining succession plan, the resulting extraction project is scientific and reasonable, feasible.
