摘　　要：针对汪家寨矿C409复杂难采厚煤层合理开采方法选择进行了研究。首先,为进一步增加开采方法选择的直观性,就三种厚煤层开采方法一般适用条件及选择原则以表格形式进行了总结;其次,具体分析了C409复杂难采厚煤层开采需着重考虑的不利因素。在此基础上,进行了C409厚煤层开采方法选择对比分析和适应性综合评价。结果表明,在现有开采技术条件下,C409厚煤层采用放顶煤开采较合理,这与矿井目前实际采用的开采方法是一致的。最后,针对C409复杂难采厚煤层放顶煤开采可能遇到的问题,给出了具体建议,以指导其安全高效开采。This paper carries out a research on selection of reasonable mining method of C409 complex and hard-mining thick coal seam in Wangjiazhai Coal Mine. First, in order to make the selection of mining methods much more convenient, the general application conditions and selecting principles of the three thick coal mining methods were concluded in the tables. Second, the negative factors of mining which requires special attention were analyzed. Then, a comparison analysis and comprehensive evaluation of mining method selection were carried out. The results show that, top-coal caving method is reasonable for C409 thick coal seam mining under present mining technology conditions, which is consistent with the actual mining method. Finally, this paper gives suggestions on problems that may occur during C409 complex and hard -mining thick coal seam top-coal caving, to guide the safe and efficient mining C409 coal seam.
