高坑矿主斜井在建成后的十几年中，虽经多次采用锚网、钢轨棚加混凝土垫板等措施加固井筒，仍发生严重变形和破坏。之后进行了注浆综合处理，采用组合注浆锚杆及喷射混凝土支护对井筒进行修复加固，共实施５０余米。两年来观察表明，注浆加固段仍完好无损，取得了良好的技术经济效果，具有推广应用价值。
In the ten-odd years after the completion of the main pit of the pit pit mine, serious deformation and destruction still occur despite the reinforcement of the wellbore by multiple measures such as the use of anchor net, steel shed and concrete padding. After grouting integrated treatment, the use of grouting anchor and shotcrete support for wellbore repair and reinforcement, a total of more than 50 meters. Observations over the past two years show that the grouting reinforced section is still intact and has achieved good technical and economical results, with the promotion and application value.
