摘要
通过分析尾矿库所处工程地质及水文地质条件,对尾矿库堆积坝进行钻探勘查,研究堆积坝受力特征及宏观稳定性.同时为避免勘查钻孔形成渗漏通道引发地质灾害,危害周边生态环境,从回填封孔、溶洞钻孔封孔以及封填封孔等3 种封孔方案中进行封孔设计,保障尾矿库安全以及选矿厂的高效生产.
Abstract
By analyzing the geology and hydrogeological conditions of a tailings dam,drilling exploration of the accumulation dam was conducted to study its stress characteristics and macro-stability.At the same time,to prevent geological disasters caused by exploration drill holes turning into leakage paths that could harm the sur-rounding ecological environment,three sealing solutions were considered,including backfill sealing,karst cave drilling plugging,and cementation sealing.Sealing design was carried out to ensure the safety of the tailings dam as well as the efficient production of the mineral processing plant.
