大乘煤矿急倾斜煤层巷道放顶煤采煤法区段高度研究

摘要

运用用模糊数学综合评判法得出该矿采用巷道放顶煤采煤法的可行性,用弹塑性理论结合大乘煤矿现场实际资料来确定分段高度,并总结出区段高度的影响因素.对同类矿井的生产具有很大的借鉴作用.%Fuzzy comprehensive evaluation method is adopted to study the feasibility of mine tunnel caving mining method. The section height is determined by elastic-plastic theory combined the practical material in Dacheng Coal Mine field and summarizes the influencing factors of section height, which provides great reference to similar coal mine.
