摘要

针对同忻矿石炭二迭系3-5号煤层"头顶"多层侏罗系采空区,采空积水量大、面积广、采空水PH值极低等复杂特点,利用地面、井下综合手段探测多层采空积水,并建立了由五大排水模式组成的立体排水系统。本技术的应用准确探明了上覆各层采空区积水状况,彻底排除了采掘工作面水患危害,实现了同忻矿工作面生产正常衔接。
        In view of the complex characteristics of the "head" multi layer Jurassic coal mining area of the No. 3-5 coal seam No. two of the Tongxin ore coal seam, the large amount of goaf, the wide area and the low p H value of the goafare very low, the ground and downhole comprehensive methods are used to detect the multi layer goaf wateraccumulation, and a three-dimensional drainage system composed of five drainage modes is established. The applicationof this technology can accurately detect the water accumulation in the overlying layers of the goaf, completely exclude thehazards of the mining face, and realize the normal connection of the production face of the Tongxin mine.
