Exploration and Evaluation of Goaf Based on Comprehensive Geophysical Technology
The paper is based on the goaf of the Miaoli coal mine located in the Ruzhou-Fangcheng section of the Jiaozuo-Tanghe Expressway,using high-density resistivity method and micro motion method to detect the distribution of coal mine goaf at the Zhangbaqiao interchange site.Finally,by comparing and analyzing the detection results of the two methods,it was found that the coincidence rate of the plane distribution of the abnormal goaf predicted by the two methods is high,and the results can confirm each other.
