| 摘 要： | 为了对采空区含水性进行勘探，采用瞬变电磁法，根据采空区地球物理特征、瞬变电磁法特征、正演结果分析以及综合试验，对仪器最优参数进行了选择和确认；通过模拟，对采空区的含水性进行了勘探。研究得出:研究区A区域的采空区富水性较差，结合工程实际情况，证明了该方法预测采空区含水性的准确性。该研究为煤矿编制采空区防治水方案提供了技术支持，并为煤矿的安全回采提供了可靠的地质资料。

| Abstract: | In order to explore the water-bearing capacity of goaf，transient electromagnetic method was used to select and confirm the optimum parameters of the instrument according to the geophysical characteristics of goaf，TEM characteristics，forward results analysis and comprehensive test.The water-bearing capacity of goaf was explored by simulation.The results showed that the goaf in area A of the study area was poor in water-rich.Combined with the actual situation of the project，the accuracy of this method in predicting water-bearing capacity of goaf was proved.This study provided technical support for the preparation of goaf water control scheme in coal mine，and provided reliable geological data for the safe mining of coal mine. |
