Abstract

Abstract: Aiming at the problems of rock burst can't meet the needs of monitoring and early warning accuracy. It proposed the methods of CT Static Stress Detection-Microseismic and Drilling Stress Dynamic Monitoring-Drilling Cuttings Verification through theoretical research and field measurement. It showed that by field measurement of 3306 working face in yangcheng Coal Mine: The results of static detection are entirely consistent with dynamic detection; Applying this method in 3306 working face, the rock burst hazards which in front of working face 30-50m, 80-100m, 130-140 m and 180-200 m are determined. Targeted measures were taken to solve the danger on the spot. and practiced control by regional and improved the efficiency of anti-scour finely. Safe mining in this area has been realized.
