摘要
对阜新五龙矿、海州立井、孙家湾矿和王营矿的冲击矿压情况做出分析和总结,得出阜新矿区冲击矿压的一般规律,发现地质构造和煤柱是影响阜新冲击矿压的两个重要因素,并采用数值模拟方法研究了地质构造和煤柱对冲击矿压的影响。
In this paper, the statement of rock burst in Fuxin Wulong mine, Haizhou shaft, Sunjiawan mine and Wangying mine is analyzed and concluded, then the common rule of rock burst in Fuxin region is obtained. Authors discovered geology structure and coal pillar are two important factors of rock burst, and studied the influence of geology structure and coal pillar to rock burst using numerical simulation method.
