深井软岩条件下冲击地压的预防和治理技术

The technology of prevent and control Rockburst in the conditions of deep and Weak Rock mine

随着矿山开采的大规模进行和采深的加大,在大采深和高应力作用下,矿井巷道围岩多表现出显著塑性变形特征,即表现出软岩性质。一方面,深井软岩条件下随巷道围岩变形,部分聚集在围岩中的弹性能得以释放,降低了巷道围岩发生冲击地压的危险性,另一方面,也给矿井冲击地压的预防和治理带来了一定的难度。

As the increase of Mining scale and Mining depth, in the conditions of big Mining depth and high stress, the surrounding rock of mine roadway always Shows significant plastic deformation characteristics, that is, show Weak Rock properties. On the one hand, with the deformation of Surrounding rock in the condition of deep and Weak Rock, part of elastic energy in rock can be released, and meanwhile, the danger of Rockbnrst occurred in Surround- ing rock will be reduce. On the other hand , the difficulty level of prevent and control Rockburst in the conditions of deep and Weak Rock mine increase.
