为给防治八连城煤矿瓦斯灾害提供依据,根据该矿实测的19号煤层瓦斯含量、瓦斯压力等数据,结合矿井地质条件,分析了其瓦斯地质规律。运用多元回归分析法预测瓦斯含量,并对其煤与瓦斯突出危险性进行了预测。结果表明:19号煤层顶底板围岩岩性致密,透气性差,封闭条件良好。岩浆岩侵入区煤层瓦斯含量增大,并且随埋藏深度增加而增大。基于不满足单项指标的要求,19号煤层不具有煤与瓦斯突出的危险性,认为岩浆岩侵入区是瓦斯治理的重点区域。

In order to prevent and control the gas disaster, according to the gas content, gas pressure and other data measured from No.19 seam, in combination W ith the mine geological conditions, the gas geological law was analyzed.The multi element regression analysis method was applied to predict the gas content and predic t the danger of the coal and gas outburst.The result showed that the surrounding rock lithology of the roof and floor in No.19 seam was compact, the permeability was p oor and the sealed condition was excellent. The gas content of the seam in a magmatic rock intrusion area would be increased and increased with the depth increased. Due not to meet the requirement of a single item index, No.19 seam would not have the danger of the coal and gas outburst and the key area of the gas control would b e the magmatic rock intrusion area.
