大同矿区冲击地压综合防治体系评价及优化
Evaluation and Optimation of Comprehensive Prevention and Control System for Rock Burst in Datong Mining Area
-
摘要: 以大同矿区坚硬煤岩体条件下浅源冲击地压为主要研究对象，调研分析了大同矿区冲击地压的显现特征。通过对煤岩体性质、地质条件、多煤层开采技术条件等进行分析，探讨了各影响因素对大同矿区冲击地压发生的影响。结合忻州窑矿冲击地压发生实例，分析了不同因素组合情况下的冲击地压发生情况。同时，介绍了大同矿区冲击地压危险区域的划分、监测预警和综合解危实践，对大同矿区冲击地压综合防治体系进行了评价和优化。Abstract: Taking the shallow-source rock burst of Datong Mining Area under the condition of hard coal and rock mass as research object, we research and analyze behavior characteristics of rock burst in Datong Mining Area. By analyzing coal and rock properties, geological conditions and multiple seam mining conditions, the influence of each factor on the occurrence of rock burst is discussed. Combining with practical examples of Xinzhouyao Coal Mine, different combinations of factors affecting rock burst is analyzed. At the same time, the division, monitoring and comprehensive prevention and treatment of hazard area are introduced, and then the comprehensive control system of rock burst in Datong Mining Area is evaluated and optimized.
