摘要
根据辛置煤矿底板下三带的现场测试成果,分析了开采煤层底板破坏带厚度、阻水性变化以及破坏带时空特征,提出了评价带压开采的最小临界突水系数,为辛置煤矿带压开采评价提供了符合实际的评价依据,成果可为其它矿井借鉴采用。
Based on field test results of three underlying influential regions below coal seam floor in Xinzhi coal mine,the failure depth,water resistance and space-time characteristics of coal seam floor failure were analyzed.A minimum critical water inrush coefficient which can provide a practical evaluation basis was established to evaluate the mining condition under water pressure.This research result can be referential for other coal mines.
