摘　　要：地面定向多分支孔注浆在煤田防止水领域已广泛应用,在多分支孔注浆工作中,成孔与注浆交替进行。注浆站外供水、内供水及注浆管路处在露天环境下,在冬季施工管路防冻是注浆工作必须解决的问题。在东庞煤矿西庞井地面区域治理二期工程中,用盐水置换管路中的清水,成功解决了这一问题。Ground directional multi-branch hole grouting has been widely used in the coal field prevention water field,in multi-branch hole grouting, holing and grouting alternately. External water supply, internal water supply and grouting pipeline are in the open air environment, pipeline anti-freezing construction in winter is a problem that must be solved in the grouting work. In the second phase of the Xipang Well Ground Area Treatment Project of Dongpeng Coal Mine, we replaced the clear water in the pipeline with salt water and successfully solved this problem.
