Application of audio frequency electric perspective technology in mine water disaster prevention

Abstract

Based on the geophysical characteristics of the top and floor strata of No.8 coal seam in Sitai Mine, through the reasonable site arrangement of measuring points and rigorous indoor data processing and analysis, the use of audio electrical perspective technology to detect the top and floor low resistivity abnormal area in 80207 working face. According to the detection results, combined with the existing hydrogeological data of Sitai mine, the relative water-bearing area and the key water control area of the working face are delineated. The results show that the audio frequency electric perspective technology can provide a basis for the prevention and control of mine water disaster conveniently and effectively.
