有底柱分段崩落法在8^(#)矿体无轨开采中的应用

Sublevel Caving with Pillars Application in Trackless Mining of 8^(# )Orebody

有底柱分段崩落法是云锡大屯锡矿(原松树脚锡矿)在常规有轨运输区域运用成熟的基本采矿方法,从2011年开始云锡个旧东区几大矿山迎来无轨开采变革,大屯锡矿地处云锡1360无轨基础平台腹地,一坑大马芦氧化矿生产基地试图从采矿技术、工艺、方法、设备上找寻无轨和传统工艺的有机融合,本文是有底柱分段崩落法在8#矿体无轨开采中的应用,设置合理的采矿参数,为后续深部氧化矿的开采积累经验、提供参考。

Sublevel caving method with bottom pillar is a mature basic mining method used by Yunxi Datun Tin Mine(formerly Songshuijiao Tin Mine)in the conventional rail transportation area.Since 2011,several mines in the old East area of Yunxi Gejiu have been undergoing trackless mining reform.Datun Tin Mine is located in the hinterland of Yunxi 1360 trackless foundation platform.The production base of Yikeng"Da Ma Lu"oxide mine tries to find the organic integration of trackless and traditional technology from the mining technology,process,method and equipment.This paper is the application of sublevel caving method with bottom column in trackless mining of 8#orebody,and sets reasonable mining parameters,so as to accumulate experience and provide reference for the subsequent mining of deep oxide ore.
