粘土固化注浆在污水库防渗中的应用研究

Researchand Application of Clay-solidified Grouting in Anti-seepage Works of Wastewater Reservoir

调查了某铜矿酸性矿坑水的危害,分析了粘土固化注浆帷幕在矿山酸性污水库坝基防渗中的适应性。某矿山酸性污水库坝基防渗工程中帷幕注浆的实践表明,粘土固化注浆技术可以有效充填地层空隙,降低地层的渗透系数,从而实现对酸性污水的封堵和控制。

The negative influences of acidity waste water in copper mine were investigated. The adaptability of clay - solidified grouting curtain applied into the seepage prevent of dam foundation of the acidity water reservoir was analyzed. The application in the actual engineering of some mine shows that the stratum interspaces can be effectively filled with the clay - solidified grouts and the permeability coefficient of the stratum can be reduced by clay - solidified grouting technology and the acidity water is controlled and blocked up.
