山东肥城煤田新陶阳煤矿中三井田下组煤7、8、9、102煤层开采受底板四灰、徐灰、奥灰高承压水威胁严重,采煤必须治水,而最先治理的就是四灰含水层的威胁。中三井田四灰含水层的边界条件为＂三面阻水,一面进水＂,四灰含水层较薄和相对封闭的水文地质单元,给实施帷幕截流提供了天然的条件。通过多年对南部进水边界F39、F40断层的帷幕截流,成功封堵了侧向补给,帷幕效果明显,解放了煤炭资源储量400万吨。

The 7,8,9,102 coal seam of middle third mine are threaten by high pressure water of 4 -limestone, Xu -limestone and Ordovician limestone in new Taoyang coal mine of Feicheng in Shandong province. The threaten of 4 - limestone aquifer should be solved before mining. The boundary conditions of 4 - limestone aquifer of middle third mine is that three side is resis- tivity water layer and one side is influent layer. The thinner 4 - limestone aquifer and relatively closed hydrology geology unit pro- vide natural conditions for curtain closure. After doing curtain closure of F39, F40 in south water boundary, plugging lateral re- charge successfully, and it has obvious effect on curtain, and liberating 400 million tons coal resource.
