【摘要】 基于唐山沟开采煤层12#上部地层的地球物理特征,通过合理布置点距、线距以及严谨的室内数据处理解释,运用瞬变电磁法小线框技术探测了测区内8#、11#煤层高低阻分布范围。根据唐山沟矿的水文地质资料及物探处理结果圈出测区内的采空区及积水分布范围。结论表明:采空区积水与围岩电性差异明显,瞬变电磁法能够圈定近距离煤层采空积水区分布范围,为煤矿安全生产及水文地质工作提供依据。更多还原

【Abstract】 Based on the 12#coal seam in Tangshangou ditch geophysical characteristics of the upper strata, through reasonable arrangement pitch line spacing and rigorous indoor data processing and interpretation, using transient electromagnetic method to detect a small frame technology surveyed area8#, 11#coal seam low resistance distribution. According to the hydrogeological and geophysical data processing results of Tangshan coal mine circled goaf and water distribution in the survey area.Conclusions show: goaf water and rock electrical differences are significant, transient electromagnetic method can delineate the distribution range close coal gob water district, provide the basis for the production of coal mine safety and hydrogeological work.更多还原
