摘要
抚顺煤田矿震的平均发震频度达4000次/年,强度急剧增大,已发生ML=3.7级矿震,研究预测表明最大震级可达4.2级。矿震是由煤田开采引起的,是矿山开采伴生的动力现象。矿震分为断层活动型、顶板活动型和工作面冲击型三种。矿震不会造成地面灾害,但是,矿震与其他潜在地质灾害相互作用具有不容忽视的危害性。讨论矿震与城市防震、滑坡、区域地质构造活动之间的相互作用。
At present the average frequency of mining tremors amounts to 4,000 times per year and ML=3.7 in vibration strength suggest a growing mining tremors energy.The mining tremors are caused by exploiting coal bed and usually exists as a concurrent dynamic happening in mine exploitation.The mining tremors are classified into three types, that is, fault effect, crest-board stress and site impact. However, in the interaction between mining tremors and other potential geologic disasters, there exists a very sevious hazard. This paper accordingly dealts with the interaction among mining tremors, slide, local geological formation effects.
