摘　　要：矿震主要发生在井下,具有突发性、连锁反应的特点,给井下安全生产带来很大危害,也对地面设施构成破坏和威胁。冲击地压是矿震的一种形式,每一次冲击地压的发生都与岩体震动有关。矿震诱发的冲击地压灾害是鹤岗矿区主要灾害之一,统计分析鹤岗矿区权属矿井发生的数十起冲击地压及伴随的矿震,可分为煤体应力型矿震、煤柱失稳型矿震、构造诱发型矿震和厚硬顶板断裂型矿震,不同类型矿震产生的原因及其诱发冲击地压机制各不相同。矿震形成的动载是冲击地压发生的重要力源,动载扰动对煤岩体的致裂、闭锁作用以及与煤岩体自身的静载共同作用诱发煤岩系统发生冲击破坏。Mine earthquake mainly occurs in the underground,with the characteristics of sudden and chain reaction,which brings great harm to the underground safety production,and also constitutes damage and threat to the surface facilities.Rockburst is a form of mine shock.Every occurrence of rockburst is related to rock mass vibration.The rockburst disaster induced by the mine shock is one of the main disasters in Hegang Mining Area.The statistical analysis of dozens of rockburst and the accompanying mine shock occurred in the mine owned by Hegang Mining area can be divided into coal body stress type mine shock,coal pillar instability type mine shock,structure induced mine shock and thick and hard roof fracture type mine shock.The causes and induced rockburst mechanism of different types of mine shock are different.The dynamic load formed by the mine earthquake is an important force source for the occurrence of the rockburst.The dynamic load disturbance causes the coal rock mass to crack and lock up,and the static load together with the coal rock mass itself induces the coal rock system to impact damage.
