摘　　要：为揭示开滦矿区瓦斯赋存分布规律,根据开滦矿区的范各庄、林西矿、吕家坨、东欢坨、钱家营、唐山矿6个生产矿井地质构造分布特征,将其各个生产矿井划分各自对应瓦斯地质单元。研究开滦矿区地质构造、岩浆情况、水文地质条件、煤层埋藏深度等因素对瓦斯赋存影响。结果表明,开滦矿区煤层瓦斯主要受地质构造因素影响,因此以地质构造为主要依据对开滦矿区进行瓦斯地质单元划分。In order to discover the gas occurrence characteristics of Kailuan Mining Area,the geological structure,magmatic conditions,hydrogeology of Fangezhuang Mine,Linxi Mine,Lujiatuo Mine,Donghuantuo Mine,Qianjiaying Mine and Tangshan Mine in Kailuan Mining Area were studied.The effect of geological structure,magmation,hydrogeology conditions,coal seam burial depth nd factors on the gas occurrence were studied.The research result shows that the coal seam gas in the Kailuan Mining Aera is mainly affected by geological structural factors.Therefore,the gas geological unit is divided in the Kailuan Mining Aera based on geological structure.
