Experimental Research on Device with Multi-Turn Overlapping Loops by Applying Mine TEM

Abstract

According to the special work environment in underground coal mine, a qualitative research is done to find the relationship among the turn-off time, the quality of received signal and the device with overlapping loops with different areas, different shapes and different turns. Through a detection experiment, the above relationship is gotten, and a design of the device with overlapping loops is proposed. Then the developed device with overlapping loops is used in engineering detection. The result shows that the device with overlapping loops can be used in coal mine underground to carry on advanced detection of geological rich-water body probably existing ahead of the heading face.
