摘　　要：为了有效保护环境水资源,实现矿产资源的合理开采,矿山治水常采用帷幕注浆手段,在遇到溶洞发育地段时,常表现出透水性强、注浆量大,难达到结束标准等现象,根据中关铁矿帷幕注浆工程中所遇到的溶洞特点,将溶洞划分为不同的类别,在实验的基础上进行了注浆添加料的选择,从理论的角度介绍了溶洞注浆的方法以及浆液扩散形式由"管道流"向"渗流"的转化过程,并对现场操作进行了详细的介绍,对于类似工程帷幕注浆溶洞处理具有一定的借鉴作用。In order to effectively protect the groundwater resources and rationally exploit mineral resources,curtain grouting is the main method for water control in mine.But in the cave development section,because of strong permeability and large grouting volume,it is difficult to come up to the grouting finished standard.According to the cave features of curtain grouting engineering in zhongguan iron mine,caves were divided into different categories;on the basis of the test,grouting adding materials were chosen.The paper theoretically introduced caves grouting method and transformation process of slurry spreading from ＂pipe flow＂ to ＂seepage＂ with field operation description.
