摘要
由于南关郝家掌进风井工作面突发涌水,井筒井壁浇筑困难,安全隐患大,经涌水测量、涌水估算分析,提出采用工作面预注浆封堵漏水点,确定注浆工艺、效果验证,取得良好经济效益,为类似条件井筒防止水治理提供经验。
Due to the sudden water gushing in the working face of the air inlet shaft in Haojiazhang,Nankan,it is difficult to cast the shaft wall,and the hidden danger is great,good economic benefits have been obtained and experience has been provided for the prevention and treatment of water in similar condition shafts.
