摘要
随着煤炭开采深度的增加,岩石与瓦斯突出日益严重,其危害不亚于煤和瓦斯突出。突出危险性的准确预测是防突措施优劣成败的关键和首要环节。1995年3月9日,海石湾矿井发生了特大型砂岩和瓦斯突出。作者综合运用多种现场观测和室内试验方法,对该井筒接下去的含气岩层的突出危险性进行了宏微观综合评价。工程实践证明预测是准确的。
Rock gas outburst becomes more and more serious with the increase of mining depth. Its danger is neither inferior to that of the coal gas outburst,nor studied as fully as the latter. Based on the comprehensive analysis of the field observation and laboratory examination, outburst prediction has been made for the underlying strata, which are in the same gas and oil bearing section as the lattest outburst according to the geological survey. The prediction has been proved accurate by the engineering practice.
