| Abstract: | 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. |
