摘要
通过对开平向斜瓦斯生成、赋存、运移等方面研究,并分别从地质构造、水文地质及岩浆侵入特征方面分析了瓦斯赋存的地质控制因素。研究表明:3个含水层及推覆构造是研究区瓦斯异常的主控因素,尤其是地下水滞流区,煤层瓦斯富集,形成高瓦斯富集区。
Kaiping syncline were selected to study generation,migration,emission of gas,and the geological control factors of gas occurrence were analyzed comprehensively from geological structure, hydrogeological conditions,magmatic intrusion of coal seams.The results demonstrated that aquifer and the nappe structure are the main controlling factors of the gas anomaly in study area.Especially stagnant area of groundwater, enrichment of coal bed gas to form gas enrichment region.
