淮北矿区海孜煤矿覆岩隔离注浆技术

Isolated Grouting Technology of Overburden in Haizi Coal Mine,Huaibei Mining Area

绿色矿山建设成为行业共识,众多煤矿都在积极探寻高效环保的新型生产方式。淮北矿区海孜煤矿将矿山充填技术与矿井废弃物处理有机结合,采用了矸石覆岩隔离注浆充填技术,介绍了技术的背景、思路、原理以及实际应用情况。该技术能有效减少地面塌陷及地裂隙等地质灾害,同时消除地面煤矸石大量堆积导致的对矿区生态环境的破坏,实现经济效益和社会效益双达标。该技术可为矿山绿色开采提供新思路、新方法。

The construction of green mines has become the industry consensus.Many coal mines are actively exploring new production methods with high efficiency and environmental protection.Haizi Coal Mine in Huaibei Mining Area has successfully used the gangue overburden isolation grouting filling technolo⁃gy by combining the mine filling technology with the mine waste disposal.The background,idea,principle and practical application of this technology are introduced.This technology can effectively reduce the ground collapse and ground fissures and other geological disasters,and eliminate the damage to the ecological envi⁃ronment of the mining area caused by a large amount of ground coal gangue accumulation,so as to the stan⁃dard of both economic and social benefits are achieved.The application of this technology can provide new ideas and methods for green mining.
