崔家寨煤矿E11510工作面防治水技术

Research on Water Prevention and Control of E11510 Coal Mining Face in Cuijiazhai Mine

采用坑透和音频电透技术对崔家寨煤矿首采区南翼的E11510采煤工作面底板O1灰岩富水性进行了勘探,发现距工作面20~50 m处的下伏O1灰岩受下伏奥灰水影响较大,该区域的水文地质情况在本井田内具有一定的代表性。并在E11510工作面采前和采后分别采取了防水、探水、排水、疏水、截水等防治措施,达到了较好的防水效果。

The evaluation on the rich water property of O1 limestone under the floor of E11510 coal mining face in the south wing of the first mining block in Cuijiazhai Mine was conducted with the mine roadway penetration and audio frequency electric penetration.It was found that the O1 limestone was highly influenced by the Ordovician limestone water at the depth of 20 to 50 m.The hydrological conditions in this area could be a certain representativeness to the minefield.The water prevention,water survey,water drain...
