摘要
在分析中关铁矿水文地质条件的基础上,确定了该矿山治水采用全封闭帷幕注浆的堵水方案。在施工过程中,对西线帷幕注浆工程采用叠加效应分析、离散性分析、高密度物探测试及检查孔检验等手段进行注浆幕体施工质量及防渗效果检查和评价,结果表明,帷幕注浆参数设计合理,帷幕体具有较好的抗渗性能,可满足矿山治水和安全开采的要求。
Based on the analysis on hydro-geological conditions in Zhongguan iron mine,a closed grouting curtain project was designed for water control in the mine.The construction quantity and water plugging effect of the western curtain grouting engineering was checked up and evaluated by means of additive effect analysis,discreteness analysis,cross-well high-density resistivity technology and examination holes.The results showed that the designed parameters of curtain grouting are reasonable,the grouting curtain has good anti-permeability and can meet requirements of mine water control and safety mining.
