新集二矿 111310 4泄排巷掘进时出现较大范围的涌水 ,涌水量较大且相对稳定 ,为新集矿区所少见 ,出水机理较为复杂。就该巷的充水水源和导水通道进行了初步分析 ,为下一步治理方案的确定、今后 13 1煤的开采布局及防治水提供了参考。
Xinji No.2 Mine 111310 4 A large area of gushing water occurs during drainage tunneling. The water inflow is relatively large and relatively stable, which is rare in Xinji Mining Area. The mechanism of water discharge is complicated. A preliminary analysis of the water supply source and the aqueduct of the alley is provided for reference for the determination of the next treatment plan and for future coal mining layout and prevention and control of water.
