摘　　要：井筒被淹没以后,井筒内水位达到静态平衡,在井口以下280 m处,井筒直接淹井深度高达400 m,先进行抛渣11 m,再追排水到抛渣面,在抛渣面浇筑混凝土止浆垫,进行工作面注浆,涌水量由313~500 m^(3)/h,减少到3 m^(3)/h,实际消耗20~40 mm石子810 m^(3),消耗水泥302 t,注浆治水实际工期95 d。After the wellbore was submerged,the water level within the wellbore reached a static equilibrium.At a depth of 280 m below the wellhead,the wellbore was directly flooded to a depth of up to 400 m.First,11 m of debris were cast,followed by drainage to the debris surface.A concrete grout stop pad was poured on the debris surface,and grouting was performed on the working face.The water inflow volume decreased from 313-500 m^(3)/h,ultimately reducing to 3 m^(3)/h.A total of 810 m^(3) of 20-40 mm stones were consumed,along with 302 t of cement.The actual duration of grouting and water control was 95 days.
