巷道突水分析及槽波地震法探明小断层的应用

Water Inrush Analysis and Application of Groove Wave Seismic Method to Detecting Faults

新景煤矿15010工作面回风巷掘进期间数次出现异常突水的现象,严重影响矿井生产的效率和安全。通过理论分析、数值计算,表明其主要突水水源为煤层上方的砂岩含水层,突水通道为原始导水断层。故采用槽波地震勘探法探测工作面范围内断层的详细分布,为合理布置巷道位置和巷道掘进过程中的水害防治提供可靠的地质依据。

To solve the abnormal water inrush during the ventilation roadway excavationat 15010 working face of Xinjing Colliery,the author proposes the groove wave seismic method to detect the detailed faults distribution after determining the source of the main water inrush is the sandstone aquifer above the coal seam and the water channel is the original water-conducting fault through theoretical analysis and numerical calculation,which can provide a reliable geological basis for the rational roadway layout and the water disaster prevention during the tunneling process.
