In the actual production of mines, in order to arrange the engineering more reasonably and achieve safe mining, it is necessary to understand the hydrogeological situation of the area in advance and take targeted preventive or treatment measures in advance. To address this situation, by studying the accuracy of the application of various physical prospecting methods in Linxi Mine, the factors affecting the accuracy of physical prospecting were derived, so that the physical prospecting methods can be more targeted and ensure the safety of coal mine production.
