The Techniques of Grouting Management for Gushing Water of Fault Fracture Zone

Gushing water in deep well and roadway has become a crucial technique problem which threatens mining safety. Taking advantage of transient electromagnetic, high-density electrical method and a combination of geological analysis, drilling testing analysis, an analytical method for gushing source and path was proposed, and types of gushing water were sorted in light of the cause of formation and governing strategies. Each gushing characters were systematically studied, thus forming the corresponding governing key techniques. Governing methods and main qualification for surrounding rock safety were proposed, with a careful consideration of the surrounding rock safety during grouting. The achievements are widely used in Guotun coal mine in Juye coal field with success, which offers a reference for similar engineering.
