煤矿导水通道探查与水害综合防治技术研究

针对水文地质条件复杂矿井其充水水源和导水通道难以确定,单一的防治水技术无法取得满意的防治水效果的问题进行研究,提出了通过地面物探、现场踏勘、地表水流量监测及水文、地质、气象资料综合分析等多种手段探查矿井充水水源及导水通道的方法,并据此研究矿井水害综合防治技术。以水文地质条件复杂的平煤股份七矿为例,用综合探查方法查明了七矿的充水水源和导水通道,并据此制定了地表河道局部硬化和导水通道地面注浆截流的综合治水方案。初步实施后,评估表明七矿充水水源和导水通道探查准确,所采取的综合防治水措施效果良好。故综合探测方法可准确确定水文地质条件复杂矿井的充水水源及导水通道,综合防治水措施的防治水效果良好。

STUDY ON WATER-CONDUCTING CHANNELS EXPORATION AND WATER CONTROL TECHNOLOGY IN COAL MINE

It is difficult to find out water source and water-conducting channels in some coal mine with complex hydrogeological conditions, and simplex technology of water control may be not satisfying in this kind of coal mine. Geophysical prospecting, site reconnaissance, flow monitoring in sections of rivers, and analysis of exiting hydrological and geological data are all used to find out water source and water-conducting channels, and compositive water control technology is studied for them. Take the No.7 coal mine of Pingmei Group for example, many methods are adopted to find out the water source and water-conducting channels of No.7 coal mine, and the scheme of hardening part of river way and intercepting water-conducting channels by grouting is worked out. The effect evaluation of the scheme shows that water source and water-conducting channels of No.7 coal mine are located accurately, and the effect is satisfying. Applying many methods synthetically can accurately find out water source and water-conducting channels in the coal mine with complex hydrogeological conditions, and compositive technology of water control can be satisfying.
