| 摘 要： | 洞湾煤矿位于贵州省晴隆县城以西，含煤地层为龙潭组砂泥岩层，主采煤层为10、22、24、25、26五层，目前开采深度为175m，已形成大寨滑坡及五个塌陷区，通过分析计算，本区煤层的安全开采深度为3 363m。煤层开采会引起滑坡、地面塌陷等地质灾害，为此提出了设置禁采区，拟建污水处理厂，综合利用煤矸石，建立地面移动变形观测站等矿山环境保护与综合治理的技术方法。

| Abstract: | The Dongwan eoalmine is locating to the west of Qinglong county seat, Guizhou Province. Coal bearing strata is Longtan Formation sandstone and mudstone, main mineable five coal seams are Nos.10, 22, 24, 25 and 26, and mining depth at present is 175m, however, the Dazhai landslide and 5 subsidence areas have already formed since mining. Through analyses and estimations, the safe mining depth is 3363m in this area. Because of coal mining can give rise to geological hazards of landslide, surface subsidence, therefore, coalmine environmental protection and comprehensive treatment technical measures including to set mining prohibitory area, construct sewage disposal plant, comprehensive utilization of gangue, establish observation station of ground movement put forward. |
