扎塘赤泥堆场在 80至 90年代曾发生岩溶渗漏 ;通过地质、水文地质、勘探等工作 ,初步查清了该场向牟老泉和向百花湖方向的岩溶渗漏通道。通过采取降低碱耗 ,封堵落水洞 ,赤泥铺盖 ,加大回水 ,垂直帷幕灌浆等综合治理措施 ,历时 10年 ,实现了在岩溶发育地带对高浓度碱水进行防渗治理的预定目标 ,杜绝了扎塘赤泥堆场废水外排 ,取得了显著的防渗效果
The karst leakage happened in Zhangtang red mud yard in 1980s and 1990s. Through the work of geology, hydrogeology and exploration, the karst leakage path to Moulaoquan and Baihua Lake was initially identified. By taking measures such as reducing alkali consumption, blocking off water hole, red mud cover, increasing backwater, vertical curtain grouting and other comprehensive treatment measures, it lasted for 10 years and achieved the predetermined target of controlling seepage control of high concentration alkali water in karst development zone , Put an end to Zhangtang red mud yard effluent discharge, achieved significant anti-seepage effect
