摘要
基于瓦斯地质学理论,以阳煤二矿为例,深入分析了地质构造、煤层埋深、围岩和水文地质因素等对煤层瓦斯赋存的影响,结果表明:煤层埋深和围岩是控制阳煤二矿瓦斯赋存的主要因素。在此基础上制定了防治瓦斯的针对性措施,即基于瓦斯赋存规律进行瓦斯抽放以及采用"双U"型通风的措施,为矿井的安全高效生产提供了保证。
Based on the gas geology theory, taking No. 2 Mine of Yangquan Coal Mining Group as an example, the analysis was conduc- ted on the geology structure, seam buried depth, the surrounding rock and hydrological conditions and other factors, then the factors which are in control of gas occurrence such as the seam buried depth and the surrounding rock were discussed. On the basis of the stud- y, targeted prevention and control measures on gas were conducted. Gas drainage based on gas occurrence law and ＂Double U＂ style ventilation measures were conducted to provide support for the safety conduction of mine.
