摘　　要：长田金矿主井井筒突水58h淹井达605m,经过采用静水抛碴注浆封堵水施工后,井筒内回水量仅为2.74m^3/h,成功恢复了井筒使用,技术经济和社会效益显著。该项技术的成功应用,验证了静水条件下抛碴注浆封堵突水技术的可行性。For water bursting the flooded main shaft in Changtian Gold Mine reached to 605 m within 58 hours.After blocking against water by dumping waste rocks in standing water and grouting,the water output decreased to 2.74m^3/h and it made the shaft back into use.The economic and social benefit was significant,which proved that this method was feasible.
