唐口煤矿F_2断层地质特征分析

Analysis of Geological Characteristics of F_2 Fault in Tangkou Coal Mine

根据已获得的地质资料,从钻孔揭露情况、三维地震探测2个方面分析了F_2断层的落差、倾角变化,并阐述了形成F_2断层的应力场变化。基于该断层的发育特征,预测了F_2断层对煤与瓦斯突出、底板隔水层稳定性及水文地质条件的影响。

According to the geological data obtained from the exposed situation of borehole, 3D magnetotelluric exploration, analyzes the changes of head and dip angle of F2 fault, and explains the change of stress field on the F2 fault. Based on these features of the fault, forecasts the possibility of coal and gas outburst, the stability of water-resisting layer under the floor of coal and the change of hydrogeological condition caused by the F2 fault.
