煤矿诱发地震研究

A STUDY ON COAL-MINE INDUCED EARTHQUAKE

综合分析了煤矿诱发地震的特征、震害、震区地震地质条件、诱震环境条件、成因类型以及成因机制。煤矿矿震是在地壳深部原始高值应力的作用下 ,由于煤系地层对外力的脆弱性 ,活动构造牵动的活化及煤矿采掘附加应力等内外因子的协调作用 ,引起地质构造薄弱面的瞬间激烈运动 ,或构造塌陷释放应力。

In this paper, the characteristic of coal-mine induced earthquake,seismic hazard,seismic geologic condition,as well as the inducing environment condition,genectic type and mechanism of coal-mine induced seimicily are all comprehensively analyzed.We believed that the coal-mine earthquakes are the internal and external effects such as the coal strata,anti-epigene brittleness, the elastic stress and strain part under the original high stress in deep crustal.Because of the active region of tractionly active tectonic and coal additional stress. That caused the transinent sharp movement on the weak interface of tectonic or the stress and strain released by the tectonic collapse.
