中文摘要：

针对急倾斜煤岩体结构隐蔽、无序开采造成采空区分布不均、浅部煤层大范围采空,严重威胁矿井安全生产的问题,以紧邻的3个煤矿为例,开展了瞬变电磁法三矿联合勘探的现场试验工作,对勘探所采数据进行了预处理、坏点剔除、滤波、高程校正、反演等工作,结合3个矿区的相关地质情况,进行了多测道曲线分析、各测线的视电阻率断面分析、各煤层的顺层切片分析、三维顺煤层切片分析、富水性综合分析等资料分析解释工作,研究得出中、强富水异常区18个,其中2个强富水区、16个中等富水区,F1隐伏断层富水异常范围小、导水性差,分析了各采空区积水情况和急倾斜煤层对其相关性等影响,为现场开采设计和灾害防治提供科学依据。

英文摘要：

For steep coal rock mass structure is concealed,uneven distribution of mined out area caused by disordered mining,and shallow coal seam with a wide range of mining space,the problem of serious threat to mine safety production. Taking three adjacent coamines as an example, field test was carried out for the combined exploration of these three coal mine by using transient electromagneticmethod,including preprocessing,reject bad points, wave filtering, elevation correction, the inversion of data, and so on. Combined withthe geological condition of three mining areas,the data analysis and interpretation work was done,which includes the multichannel curveanalysis,analysis of apparent resistivity section of each measuring line,slice analysis of coal seam,slice analysis of three-dimensional,comprehensive analysis of water rich property,et al. Results of study have shown that, 18 abnormal water areas were found out,including2 strong rich water areas and 16 medium rich water areas,and F2 ,concealed fault,whose abnormal region is small,and the water conductivity is low. The effect of steep coal seam on the correlation of the goaf and surface water supply was analyzed, which has provideda scientific basis for mining design and disaster prevention.
