Directional Drainage Grouting Technology of Coal Mine Water Damage Treatment

摘要：

Grouting has become an important and effective means of prevention and treatment to mine water disaster. Explore the rapid and efficient mechanism and grouting technology for coal mine water control work has great significance. This paper proposed directional drainage grouting based on Grouting mechanism and practice experience. It could be used for tunnel closure, collapse column water inrush and four-fuzziness (measurements are not allowed, water inrush source uncertainty, water inrush location is unknown and leading water channels is unclear) mines. And the water grouting mechanism and key techniques are discussed in detail. The water disasters treatment of Renlou coal mine and Tianhe coal mine showed that directional drainage grouting have high efficiency, save materials, large safety factor and so on. It has broad application prospects.
