断裂构造密集区域复合探测技术分析及应用

Analysis and application of composite detection technology in fault dense area

王家寨矿-510南翼总回风巷地质条件较为复杂,断裂构造较为密集,面临沟通其下奥灰含水层的危险。为实现其安全掘进,采用优势互补的复合探测技术进行分析,分析结果表明,含水异常区的范围与下部奥灰水没有直接联系,但对含水异常区应进行注浆堵水。

The geological condition of -510m southern main return airway of Wangjiazhai mine is complicated, and it has dense faulted structure and the risk of connecting the faults with the lower Oraovician limestone aquifer. In order to realize safe mining, combined detection method was used, and the results showed that there was no direct link between abnormal water bearing zone and the lower Ordovician limestone water, but in the abnormal water bearing zone grouting and blocking against water shoubt be carried out to provide safeguard for the following roadway excavation.
