综合探测技术在覆岩破坏观测中的应用研究

Application and research on comprehensive Geophysical detection technology to strata failure

从小浪底水库下采煤防治水技术工作的需求出发,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。

From the requirements of the mine water prevention and control technology for coal mining under Xiaolangdi Reservoir, it was first to apply the drilling and geophysical means combined, multi geophysical means combined and the comprehensive survey means combined with the mine surface and underground mine survey to observe and measure the strata failure law after the coal mining operation under Xiaoloangdi Reservoir. A good result was obtained from the observation and measurement. The strata failure and the height of the water conducted fissure after the coal mining operation in the seam ware correctly decided, which could provide the important parameter references and technical support to the rational design of the mining method under the reservoir in Xi＇an Mine.
