摘要
针对云南毛坪铅锌矿南部含水层构造裂隙发育的现状,采用了“垂直孔+“鱼刺型”分支孔+“S”型分支孔”的帷幕注浆方式。结果表明:黏土水泥浆在毛坪铅锌矿南部具有良好的注浆效果和适用性,多钻孔组合方式有效的增加了裂隙接触面积,注浆后地层单位透水率大幅降低,取芯孔验证浆液结石性好,可为区域同类型矿山水文地质治理提供参考。
In view of the current situation of structural fissure development in the southern aquifer in Maoping lead-zinc mine in Yunnan,the paper adopeted the curtain pulping method combined with vertical hole,fish-stinging-shaped branch hole and S-shaped branch hole.The results showed that clay cement slurry had good slurry effect and applicability in the southern part of Maoping lead-zinc mine.Multi-drilling combination effectively increased the contact area of the fissure,and the water permeable rate of stratigraphic unit decreased greatly after grouting.Samples from core-taking hole proved good coagulation ability,which could provide reference for similar mine hydrogeological control in the area.
