白集矿急倾斜松软厚煤层开采方法研究

Steeply Inclined Soft Thick Coal-seam Mining Method in Baiji Colliery

摘要: 根据白集矿急倾斜松软厚煤层赋存状况和原有的开采技术水平,结合国内外现有的急倾斜煤层开采经验,提出了适合该矿煤层开采的4种采煤方法,在技术分析的基础上,从经济角度对开采方法进行比较,并运用多目标决策进行最优选择,最终确定该矿的采煤方法,对类似煤层的开采实践具有借鉴意义。

Abstract: Combining current mining experience of steeply-inclined coal-seam,4 mining methods which fit for steeply-inclined soft thick coal-seam in Baiji Colliery were put forward.By economic comparison,multi-goal decision was applied to selecting optimal mining method.This could provide reference for mines with similar condition.
