摘要
本文介绍长坡锡矿地压研究及采空区处理技术,叙述了矿山现场地压观测方法和二维与三维有限元分析计算结果。在获得大量实测数据和分析计算资料的基础上,揭示了长坡矿地压活动的特点,评价和确定了矿区不稳定岩体的范围以及重点防范区域,提出了切实可行的采空区处理方案。
Study on ground control and mined-out area treatment is described in the paper. In-situ observing method for ground control and calculation results with two/three dimensional finite-element method are presented. Based on field measurements and calculation results, ground control in Changpo Tin Mine are revealed. Scope of unstable rockmass, particularly seriously unstable areas which need precautionary measures, are determined and evaluated. Practicable scheme for treatment of mined-out areas is proposed.
