| 摘 要： | 为提高大采深、厚煤层开采冲击地压监测预警准确性,通过理论研究和现场实践,提出了“CT(Computed Tomography)静态应力探测-微震和钻孔应力动态监测-钻屑检验验证”综合判定工作面冲击危险区的方法。并在阳城煤矿3306工作面进行现场应用,实践表明：静态应力探测结果与动态监测结果具有较高一致性|在3306工作面应用该方法确定了工作面前方30～50m、80～100m、130～140m和180～200m存在较高的冲击地压危险,现场采取了针对性的解危措施,实践了分区防治,提高了防冲效率,效果良好。

Classification and Prevention of Rockburst Dangerous Zone Based on Static Detection and Dynamic Monitoring |

| 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. |
