采空区下注浆堵水技术实践

Technology Practice of Grouting and Blocking Water under Goaf

依据固庄煤矿丈八平硐大巷采空区下涌水的特点,着重对采空区下裂隙岩体中注浆堵水的技术工艺进行了研究,开展了实际工程应用试验,并提出一套新技术途径,此种堵水方法既提高堵水效率又降低封堵成本,为提高矿井防治水管理水平、保障矿井安全生产提供了一条高效、实用的新技术途径。

Based on the characteristics of water bursting of under roadway goaf in Zhangba Pingdong of Guzhuang Mine, the technological processes of grouting and blocking water in fractured rock under goaf were studied, practical application test was carried out and a new technical approach was proposed. This new blocking water method not only improves efficiency and also reduces closure costs, which provide a new efficient and practical technology for improving management level of blocking water prevention and treatment, ensuring the mine safety production.
