| 摘 要： | 为了治理冲击矿压灾害，采用数值模拟方法研究了井巷周围煤岩体的力学特性对应力分布的影响。研究结果表明，巷道周围煤岩体的体积弹模、内聚力和内摩擦角均对应力分布有较大的影响。根据这个结果，可采用卸压爆破的方法，改变应力分布状态，减小或消除冲击矿压危险。

| Abstract: | The numerical analogy has been adopted to study the mechanic features influencing stress distribution in coal and rock around the roadway in order to control rock burst disasters. The research indicates that volume modulus, cohesion and internal friction angle of coal seam around the roadway have a great influence on stress distribution. Based on this conclusion, the state of stress distribution can be changed and the rock burst can be limited or avoided by applied shock failure method. |
