摘要
华盖山煤矿主要可采Ⅱ号煤层下存在强岩溶含水层,为划定安全开采范围,综合应用国内相关科研成果,成功地留设防水煤柱,划定可采区域。经矿井建设检验,满足安全开采需要。
There is the intense karst aquifer under the main minable seam Ⅱ of Huagaishan coal mine. In order to outline the safe range of minming, we have comprehensively utilized the relevant result of scientific study and have successfully reserved the waterproof coal block, outlined the minable area, which can meet the requirement of safe mining according to the examination in mine construction.
