井上下综合勘查在围岩气储集层探测中的应用

Application of Surface and Underground Comprehensive Exploration in Reservoir Detection of Surrounding Rock Gas

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。

Aiming at gas emission from surrounding rock in Huangling mining area, combining with themine extraction disposal, uses the comprehensive exploration technology to detecting the reservoir of surrounding rock gas. It has been found out seven reservoirs of surrouding rock gas, these include four main continuous reservoirs of surrouding rock gas and three local reservoirs of surrouding rock gas . Also main lithology and thickness and distribution of the reservoir of surrounding rock gas have been got, it provides the foundation basis for gas prevention.
