针对固隆煤业受南板桥断层影响，部分巷道受水害威胁，影响采掘安全的问题，分析了涌水、补水情况，设计了钻探及注浆工程。通过钻探工程，进一步控制了断层走向、倾角、落差，表明南板桥断层具有导水性；揭露了溶洞，表明其为地表水补给深部含水层的重要通道。据此对南板桥断层破碎带进行了注浆加固改造，有效减弱了南板桥断层上盘K2、K3灰岩与下盘奥陶系灰岩之间的水力联系，保障了固隆煤业的生产安全。

In view of the problem that Gulong Coal Industry was affected by the Nanbanqiao fault and some roadways were threatened by water disaster, which affected the safety of mining and excavating, the water inflow and water replenishment were analyzed, and the drilling and grouting projects were designed. Through drilling engineering, the strike, dip angle and drop of the fault were further controlled, indicating that the Nanbanqiao fault had water conductivity. The karst cave was exposed, indicating that it was an important channel for surface water to recharge deep aquifers. Based on this, the grouting reinforcement and reconstruction of Nanbanqiao fault fracture zone was carried out, which effectively weakened the hydraulic connection between K2, K3 limestone in the upper plate of Nanbanqiao fault and Ordovician limestone in the lower plate, and ensured the production safety of Gulong Coal Industry.
