摘　　要：为有效掌握15#煤层上覆采空区的富水情况,采用瞬变电磁技术对上覆采空区进行探测作业,通过具体分析瞬变电磁技术的原理及特点,结合工作面及上覆采空区的特征,确定测试作业时的各项参数,并通过试验的方式验证了测试参数设置的合理性,随后进行工作面上覆采空区富水性的探测作业。结果表明:15#煤层上覆9#煤层采空区内存在着4处采空区,6处积水区域,测试结果可靠性较高,15#煤层工作面推进通过探测的积水区域时应加强探放水作业。In order to effectively grasp the water-rich condition of the overburden in the 15#coal seam,transient electromagnetic technology is used to detect the overburden,and the principles and characteristics of the transient electromagnetic technology are analyzed specifically.The characteristics of the empty area,the various parameters during the test operation were determined,and the rationality of the test parameter settings was verified through experiments.Then,the detection of the water richness of the goaf on the working surface was performed.The results show that there are 4 mined-out areas and 6 stagnant areas in the mined-out area of the 15#coal seam and 9#coal seam.The test results are highly reliable.Strengthen water exploration and discharge operations.
