针对黄陵矿区煤矿开采过程中围岩气异常涌出的现状,结合矿井开拓部署和以往地质资料,采用综合勘查技术探测围岩气储集层。通过井上下综合勘查,查明勘查区赋存围岩气储集层7层,其中主要连续分布储集层4层、零星分布储集层3层,得到了各围岩气储集层的主要岩性、厚度和分布,为矿井围岩气防治工作提供了基础依据。
In view of the current situation of the abnormal emission of surrounding rock gas in the process of coal mining in Huangling mining area, the comprehensive exploration technology is used to detect the surrounding rock gas reservoir in combination with the open-pit deployment and previous geological data. Through comprehensive well-bore exploration, it is ascertained that there are 7 layers of surrounding rock gas reservoirs in the exploration area, of which 4 are mainly continuous distributed reservoirs and 3 are sporadic distributed reservoirs, and the main The lithology, thickness and distribution provide the basis for prevention and control of surrounding rock gas in mines.
