摘要
针对程潮铁矿 2号主溜井垮落后的稳定状况 ,提出了以“托斗”结构为主要支护形式的总体返修加固方案。实践证明 ,该方案不仅工期短、投资少 ,而且溜井返修后稳定性良好 。
In light of the stability problems of No. 2 main ore-pass at Chengchao Iron Mine resulting form its severe collapse, the authors have put forward the whole reinforcement scheme in which a 'support funnel structure' is its main supporting pattern. The practice has shown that the scheme has the advantages of short time limit for and low investment in the reinforcement project, and good stability of the reinforced ore pass.
