摘要
通过对百善煤矿进行提高回采上限、减小防水煤(岩)柱留设的研究和实践,对中等富水松散含水层下的煤炭进行了成功开采,既减少了国家煤炭资源的损失又提高了矿井经济效益。
Through research and practice of raising the mining upper limit and reducing the waterproof pillars in Baishan Coal Mine, the coal is successfully mined under the middle watery loose water - beaning stratum. Not only the loss of coal resource is reduced, but also the mine economic benift is raised.
