韩城矿区3号煤层属厚及特厚不稳定的“三软”煤层。长期以来,由于工作面片帮、冒顶、底板软弱等现象严重,现有的采煤方法在产量与工效等方面都未能取得较好的效果。针对这种情况。本文提出4种可行的采煤方法,经过分析、比较与计算,最后采用多目标决策方法——层次分析法进行了群组决策,给出了较优的适合于3号煤层条件的采煤方法。 No.3 coal seam of Hancheng Mining Area is thick and exceptionally unstable “three soft” coal seam. For a long time, due to the work of face-piece help, roof fall, the floor is so weak that the existing coal mining methods have not achieved good results in terms of output and ergonomics. In view of this situation. In this paper, four feasible coal mining methods are proposed. After analysis, comparison and calculation, the multi-objective decision method-AHP is adopted to make group decision-making, and the optimal coal mining method suitable for No.3 coal seam conditions is given .
