%X 煤矿开采后经过漫长的变化会形成采空区，采空区往往会造成地面沉降、塌陷等潜在的安全隐患，为了消除这些安全隐患带来的问题，并查明煤矿采空区的分布情况，本文采用瞬变电磁法和高密度电法对长春某区域进行了综合探测，介绍了两种探测方法的基本原理，并对多条测线以及不同深度的电阻率平面图和叠加图进行了综合分析，对比分析了两种方法的探测结果，经验证，两种方法探测出的采空区范围有很好的吻合，提高了探测的可信度。<br />
After a long changes, coal mining will form the mined-out area, goaf tends to cause land subsi-dence, collapse, such as potential safety hazard, in order to eliminate the safety hidden trouble problems, and find out the distribution of coal mining goaf, the transient electromagnetic method and high-density electrical method are adopted in this paper, a area in Changchun has carried on the comprehensive detection, this article introduces the basic principle of the two methods of detection. In addition, the resistivity maps and superposition maps of multiple survey lines and different depths are comprehensively analyzed, and the detection results of the two methods are compared and analyzed. It is proved that the scope of the goaf detected by the two methods is in good agreement, which improves the reliability of detection.
