摘要
介绍了抚顺煤田矿震的主要特征,用弹性回弹理论对断层型矿震的成因机理进行了深入分析,认为断层蠕动效应导致断层内部应力集中,最终使脆性和弹性岩体破裂、回弹、震动,形成了矿震。最后提出3种有效的预测该类矿震的方法。
Main properties of Fushun coalmine earthquake are discussed. The cause and mechanism of mine＇s fault-type earthquake are analyzed by means of Elastic Spring- back Theory. The analysis shows the reason for mine＇s fault- type earthquake： the effect of fault peristalsis causes concentration of fault＇s inner stresses that gives rise to break, spring-back and vibration of brittle and elastic rock bodies. Finally, 3 kinds of methods for forecasting mine＇s fault-type earthquake are recommended.
