该文结合资江煤矿的实例探讨了开采解放层时层间的岩性对突出煤层卸压的影响,认为解放层间岩性较软时其变形、移动发生在一定时间内,经过若干时间仍恢复到原始状态。因此,开采这类岩性的解放层应在适宜时间抓紧抽放瓦斯,使之充分卸压。 Based on the example of Zijiang Mine, this paper discusses the influence of lithology between layers on the relief of outburst coal during the mining of the liberated layer. It is considered that when lithology of the liberated layer is soft, its deformation and movement occur within a certain period of time. After a certain period of time Return to the original state. Therefore, the exploitation of such lithology of the liberated layer should pay close attention to draining gas at an appropriate time to make it fully pressure relief.
