摘  要:在地下矿山回采过程中,地压是由于矿山岩体弹性变性能的瞬间释放而产生的突然剧烈破坏的动力,从而破坏了矿体的稳定性.地压造成的失稳往往会造成惨重的人员伤亡和巨大的经济损失,已经成为引发矿山重大灾害的主要因素之一.尤其是深部地压的发生,主要是应力集中、应力释放的整个过程,也属于应力由开采前的平衡到开采后的不平衡的发展过程.In the process of underground mine stoping, the ground pressure is due to the power with sudden severe damagewhich is created from the instantaneous release of rock mass elastic performance of mining, which destroys the stability ofthe ore body. The pressure resulted in the instability often causes heavy casualties and huge economic losses, and becomesone of the main factors causing major disasters in mine. Especially the occurrence of deep ground pressure, it is mainly thewhole process of stress concentration, stress release, and also belongs to the development process from the stress of the bal-ance before mining and to the unbalance after mining.
