老窑水长期赋存于采空区,这就决定了其水质的基本特征。我矿近几年来利用矿井水质指导送巷方向,探放老窑水,共放水4万多米~3,减少无效进尺55000多米;扩大原设计面积40万米~2,增加地质储量160余万吨。 我矿主要含煤建造属华北石炭二叠型。目前主采山西组2号煤层,厚3.37米,原煤
Old kiln water occurs in the goaf for a long time, which determines the basic characteristics of its water quality. In recent years, mine using the mine water quality guidance to the lane direction, exploration of the old kiln water, a total release of more than 40,000 meters water 3, reducing the effective footage of more than 55,000 meters; expanding the original design area of 400,000 meters to 2, an increase of geological reserves of 160 million Ton. My coal mine is mainly composed of coal-bearing formations in North China Carboniferous. At present, the main mining group No. 2 seam in Shanxi Province, 3.37 meters thick, raw coal
