寺河煤矿东五盘区2011ZX-CC-01井井喷分析

Blowout Analysis of 2011 ZX-CC-01 Well in Dongwupan area of Sihe Mine

寺河煤矿东五盘区2011ZX-CC-01井在钻探过程中出现井喷,为了保证东五盘区回采安全,采用理论分析以及物探技术手段从断层、褶曲以及陷落柱等地质构造方面着手,对井喷原因及井喷通道进行分析,结果表明:井下部存在隐伏构造,当钻孔打到隐伏构造附近时导通了突水通道,造成突水。

Blowout occurred in well 2011 ZX-CC-01 in the process of drilling. In order to ensure the safety of coal winning in the Dongwupan area of Sihe Coal Mine,in this paper, the causes of blowout and blowout passage were analyzed from the aspects of fault, fold and subsidence column by theoretical analysis and geophysical prospecting techniques. The results showed that there are concealed structures in the underground. When boreholes are drilled near the concealed structures, water inrush channels are opened, resulting in water inrush.
