【摘要】:针对五矿306中巷在掘进中受正断层的影响,可能发生掘进工作面底板突水事故,通过理论计算对306中巷过ⅢF63断层突水危险性进行了预测,并采取超前钻探、疏水降压、增设排水系统、改变掘进工艺及注浆堵水等过断层防治水措施,消除了掘进过断层期间底板突水威胁,确保了矿井安全生产。
[Abstract]:In the light of the influence of the main faults in the heading of the roadway in the coal mine 306 , it is possible to predict the water inrush from the bottom plate of the tunneling working face . Through the theoretical calculation , the risk of water inrush of the 鈪,
