小浪底水库下采煤覆岩破坏综合探测技术研究

根据煤矿覆岩破坏观测的研究现状,从小浪底水库下采煤矿井防治水工作的需求出发,首次尝试采用钻探与物探手段相结合、多种物探手段相结合以及井上下观测相结合的综合探测手段进行小浪底水库下煤炭资源开采后覆岩破坏规律的观测,取得了较好的效果,准确判断了煤层开采后的覆岩破坏情况和导水裂隙带高度,为新安煤矿合理设计水库下开采的方式方法提供了重要的参数依据和技术支撑。

Research on Compositive Geophysical Methods in Overburden Rock Failure Detection for Mining under Xiaolangdi Reservoir

According to the research status quo of the overburden rock failure detection in coalmine and the demand of the prevention of mine water for mining under Xiaolangdi reservoir,this paper firstly attempted to combine drilling and geophysical methods,different geophysical methods,as well as above and underground monitoring to detect the law of water conducted zone for the Xin'an coal mine synthetically.The compositive detection method got the upgrowth law of the overburden rock failure & the water conducted zone effectively and provided Xin'an coal mine with some important parameters and technological support for rational design of the mining ways.
