摘要
通过对百善煤矿松散含水层下合理煤岩柱高度进行研究分析，为该矿和条件类似矿井缩小防水煤柱、提高上限采煤提供了可靠的依据。
By means of the study and analysis of rational coal and rock pillars height under the loose water-bearing strata of Baishan Coalmine, the reliable basis is provided for reducing the water-bearing barrier and enhancing the upper limit for coal mining in Baishan Coalmine and other similar coalmines.
