| 摘 要： | 介绍了矿山地震与瓦斯突出等煤矿灾害及成因， 并通过若干煤矿瓦斯突出和矿山地震的同震现象，论述了这些灾害在动力过程中的内在关系.这些震例表明，在高瓦斯煤矿， 矿山地震与瓦斯突出存在密切的相关.认为较大矿震伴随瓦斯的低值延时响应可能是瓦斯突出的预警信号.从矿震定位、震源机制、矿震成因、瓦斯突出条件等分析了矿震与瓦斯突出相关的机理. 进一步介绍了瓦斯流体对矿震的触发作用，尤其超临界流体的特殊性质在矿震发生中的重要作用.依据矿震与构造地震在机制方面的相似性， 讨论了上述结果在震源物理研究中的意义.

| Abstract: | This paper presents an overview of mining seismicity, gas outburst and their origin. The internal relation of mining seismicity and gas outburst in the dynamic process is studied on the basis of the fact that these disasters sometimes occur simultaneously. The examples show a close relationship between mining seismicity and gas outburst in high gassy coal mines. It is proposed that strong mine shocks plus the response of low value and delay time are early warning signals. The mechanism of the relationship between mining seismicity and gas outburst is analyzed by using the location of mining shocks, focus mechanism, cause of mining shocks and conditions of gas outburst. The trigger action of gas fluid on mining shocks, especially the effect of the anomalous property of supercritical fluid on the preparation and occurrence of mining shocks is discussed. According to the similarity between mining-induced earthquakes and tectonic earthquakes in terms of mechanism, the significance of the above results in the study of physics of earthquake source is also discussed. |
