The Technology of Efficient and Rapid Sealing Water Bursting Point at Up and Down Mine

Taking water control project at 11010 working face in Hezhuang Mine as an example, the paper introduced a technology of efficient and rapid sealing water bursting point at up and down mine in flowing water condition. Through implementing the technology, it not only shortened construction time, greatly reduced water control costs, but also withstood the test of drainage phase and final grouting phase and achieved efficient, rapid, low-cost, high-quality results. so it achieved the goals of reconstructing mine by quick grouting and drainage and reducing mining water discharge.
