摘要
影响煤层对瓦斯气体吸附能力的因素很多,包括构造、煤质、地温和地层压力等,在构造和煤质等因素相似的前提下,通常浅部煤层瓦斯含量随着埋深增加而逐渐增大,但是到一定埋深后,煤层瓦斯含量与埋深不再呈现简单的正相关关系。平顶山矿区逐渐进入深部开采,研究深部煤层瓦斯分布规律可以为深部矿井瓦斯防治、抽采达标等提供技术指导。
There are many factors affecting the adsorption of methane in coal seams, including the structure, coal, mild formation pressure, in the case of a similar structure and coal quality, usually shallow coal seam gas content increases with the increasing burial depth, but to a certain depth, the coal seam gas content will no longer present a simple positive correlation with the burial depth.Pingdingshan mine area has gradually entered to deep mining stage, so developing deep seam gas distribution can provide technical guidance for deep mine gas prevention and control, and drainage standards.
