摘要
以南李庄铁矿帷幕注浆工程为例,通过对钻探岩芯裂隙发育的统计整理,分析了水平、斜向和垂向3种裂隙产状对注浆扩散效果的影响,同时结合矿区构造发育特征,评价了帷幕线与裂隙之间组合形式对注浆施工及工程质量的影响,为类似工程的设计施工及堵水效果评价提供依据。
With the help of curtain grouting engineering of Nanlizhuang Iron Mine, through the drilling core fissures＂ statistics,the impact of three fissures occurrences such as the horizontal, oblique and vertical karst fissure occurrences on grouting diffusion effect were analyzed. Combined with the structural development characteristics of the mining area, the in- fluence of the combination of curtain line and karst fissures on the grouting construction and engineering quality was evalua- ted. The study provides the basis for the design and construction of similar projects and water plugging evaluation.
