摘　　要：根据邹庄煤矿井筒附近构造以及含水层地质特征,结合注浆与冻结施工工艺特点,确定采用注浆、冻结、井筒掘砌"三同时"方法对主井井筒进行建设,井筒地面预注浆工程包括直孔段注浆工程和S孔段注浆工程两部分,通过注浆较好地加固了井筒周围的岩石,取得了良好的注浆效果。According to Zouzhuang Coal Mine near wellbore structure and geological features of the aquifer,combining with the characteristics of grouting with freezing construction technology,grouting,freeze,wellbore dig build by laying bricks or stones“three at the same time”method for the main shaft well construction,wellbore ground grouting engineering including straight hole grouting engineering and S hole section grouting engineering two parts,by grouting reinforcement well the wellbore surrounding rock,good grouting results have been achieved.

关 键 词：S孔注浆 地面预注浆 注浆加固
