摘要
煤矿冲击矿压实质是煤岩体能量积聚与释放的过程,它是一个动态的过程.因此冲击矿压的防治也应是一个动态的过程,其防治过程必须使得煤岩体中所积聚的弹性应变能达不到最小冲击能,从而防治冲击矿压的发生.电磁辐射能够反映煤岩体中所积聚的能量,卸压爆破可以释放能量.三河尖矿按此思路实施的冲击矿压动态防治技术,取得了良好的效果.
The rock burst in coal mine is the process of energy accumulation and dissipation, its control must be dynamic process , caused of the rock burst is a dynamic process ,if the elastic energy accumulation in coal and rock materials is less then the minimum energy induced rock burst, the rock burst can be controled. The electromagnetic (EME) can reflect the energy accumulated in coal and rock materials, the relive-shot may dissipate energy. By above methods, the dynamic control technique of rock burst is practiced in Sanhejian coal mine, the good effect is obtained.
