摘要
老厂锡矿14-5#矿体原设计为上向式水平分层胶结充填采矿法,实践中暴露出一系列问题。运用分层空场嗣后块石胶结充填采矿法对采场结构参数进行了优化,解决了存在的问题,获得了较好的效果。
Upward type horizontal sub-level cemented filling mining method has been adopted in 14- 5^﹟ ore body of Laochang tin ore, but a series of problems exposed. Through adoption of layering open stope afterwards cemented rockfill mining method, slope structural parameters were optimized, problems were solved and good economic effects was obtained.
