随着开采深度的不断加大,动态地压的显现使得塔尔纳赫矿床的开采日趋复杂,因而降低了回采效率和安全性。冲击地压最初于1972年发生在离地表500米深的中段,其特征表现为岩石的剥落和突然裂口。近几年来,由于开采过渡到深部中段,动态地压的显现不但强度增大,而且冲击力与特性也有所变化。 With the increasing mining depth, the dynamic pressure has led to the increasingly complicated mining of the Tarnach deposit, thus reducing the efficiency and safety of recovery. Rock burst first occurred in 1972 at a depth of 500 meters from the Earth’s surface, characterized by rock spalling and sudden rips. In recent years, due to the transition from mining to the middle of the deep, the dynamic pressure has not only increased in intensity but also changed its impact and characteristics.
