摘要: 为了研究瞬变电磁法对厚煤层矿区地下水的探测效果,从数值模拟与现场实测2方面对新疆准噶尔盆地某露天矿地下水进行探测与验证。首先以测井曲线为基础建立厚煤层地电断面模型,数值模拟瞬变电磁感应二次场特征,分析理论探测效果;其次根据现场条件布置瞬变电磁测网,依据理论结果设置采集参数,对实测数据进行处理分析推断地下水分布与地质成因;最后采用地面钻探对异常区进行揭露。结果表明:瞬变电磁法适应厚煤层露天矿地电结构,能准确地反映地下水位置与范围,适合在厚煤层露天矿应用。Abstract: In order to study the effect of transient electromagnetic (TEM) on the detection of groundwater in thick coal seam mining area, groundwater in open pit coal mine in Junggar Basin of Xinjiang Autonomous Region is detected and verified from two aspects of numerical simulation and field measurement. First of all, the ground electricity section model of thick coal seam is set up based on the log curve, characteristics of TEM induction field are summed up by means of numerical simulation, theoretical detection results are analyzed. Secondly, TEM network is arranged according to the conditions of the field, acquisition parameters are set up according to the theoretical results, distribution and geological causes of groundwater are analyzed and deduced based on the real data processing results. Finally, abnormal area is exposed by ground drilling. The results show that TEM is adapted to the ground electric structure of the thick coal mine, location and scope of groundwater can be accurately reflected by TEM, and it is suitable for application in thick coal mine open pit.
