摘要 根据百善煤矿开采试验工作面的大量现场观测资料,①底含水层的水文地质条件及其渗透稳定性,②煤层开采以后覆岩变形破坏移动规律,③控制软弱顶板尤其是存在弱面的顶板控制技术。对两淮煤田浅部煤层的安全开采具有参考价值。 Based on the large number of observable informations in site on mining testing working face of Baishan coal mine, it's discussed that: (1)hydrogeological conditions of basal aquifer and its stability of permeation; (2)overlay law of deformation, destroy and movement after mining of coalbed; (3)controlled technology of soft roof. There are reference value for safely mining of coalbed in shallow part of Double-Huai (Huainan and Huaibei) coal-fields.
