为给矿井瓦斯综合防治提供指导,研究了断层对煤层瓦斯赋存的控制作用,采用瓦斯地质分析的方法,从断层力学性质、断层两盘岩性、断层规模、断层埋深和现代构造应力场等5个方面,研究了裴沟煤矿杨河井田边界走向正断层对煤层瓦斯赋存的控制作用。研究结果表明:杨河井田边界走向正断层属于开放型断层,有利于瓦斯逸散,井田中部远离边界断层处瓦斯含量较大,向深部和浅部靠近边界断层处瓦斯含量逐渐减小,煤层瓦斯赋存具有明显受断层控制的特点。

In order to provide guidance for the comprehensive prevention and control of the mine gas, the control effect of fault to seam gas deposit was studied, fr om five aspects of the fault mechanics property, upper and foot wall lithology of the fault, fault size, fault depth and stress field of the modern structure, a gas geological analysis method was applied to the control effect of the strike normal fault to the seam gas deposit in Yanghe Minefiled boundary of Peigou Mine. The study results sho wed that the strike fault in Yanghe Minefield boundary was an open fault and would be beneficial to the gas release. The seam gas content in the central part of the Min efield far away from the fault in the boundary was high and the gas content in the deep part and the shallow part near the fault in the boundary was gradually reduced. Thus the seam gas deposit was obviously controlled by the fault.
