双液浆在矿山帷幕注浆中的应用与探讨

Application and Discussion of Double Liquid Slurry in Curtain Grouting in Mine

随着矿山帷幕注浆技术与施工经验的成熟,国内各大型含水矿山在采矿过程中,对矿区地下水的处理由过去采取的疏干为主,逐渐转变为以堵为主疏为辅的方式.如,地表垂直帷幕注浆,井下近矿体包裹帷幕注浆,既有效控制了开采过程中地下水的各种危害,又极大的减少了对周边地质环境的破坏,实现生产的生态发展.在矿山帷幕注浆过程中,遇到强导水通道时,通过合理的运用水泥水玻璃双液浆,能够高效快速的实现封堵.

With the maturity of mine curtain grouting technology and construction experience,in the mining process of large-scale water-bearing mines in China,the treatment of groundwater in the mining area has been mainly carried out by the dredging in the past,and gradually changed to the way of blocking mainly.For example,the vertical curtain grouting on the surface and the curtain grouting near the ore body can effectively control the various hazards of groundwater during the mining process,and greatly reduce the damage to the surrounding geological environment and realize the ecological development of production.In the process of grouting in the mine curtain,the strong water guiding channel can be blocked quickly and efficiently as the rational use of cement water glass double liquid slurry.
