摘　　要：矿区震动能诱发多种灾害,以瓦斯突出尤为严重。以鹤岗矿区为研究对象,统计了历年来鹤岗地区地震及矿震活动规模,分析了以往典型的矿震引起的瓦斯灾害事例,总结了矿震作用下瓦斯灾害的机理,基于统计数据,提出了矿震瓦斯灾害预警需要解决的关键问题。初步研究表明:震动事件与煤矿灾害之间具有很强的关联性,呈现震动在前、灾害在后、时间间隔数分钟至数日不等的“先震后灾”的特点,基于此,通过建立矿震监测台网,给出了震动诱发煤矿瓦斯灾害预警可行性,并提出了震动引起瓦斯灾害预警思路。The shake of the mining area can induce a variety of disasters,especially the gas outbursts.This paper takes the Hegang mining area as a research object and counts the scale of shakes and mine earthquake activities in Hegang area over years.The typical examples of gas disasters caused by mine earthquakes are analyzed.The mechanism of gas disasters under the influence of mine earthquakes is summarized.Based on the statistical data,the key issues that need to be solved in early warning of mine earthquake disaster are proposed.Preliminary research demonstrates that the shake event and the mine disaster have a strong correlation.Its characteristic by“shake precedes disaster”,namely,the shake occurs previously,the disaster comes subsequently,and the time interval between them may be several minutes to several days.On the basis of this feature,the feasibility of early warning of coal mine gas disaster induced by shake is explained through the establishment of coal mine earthquake monitoring network,and the idea of early warning of gas disaster caused by shake is advised.
