摘要
Abstract
Currently,the underground mining of domestic bauxite mines mostly adopts the open-pit mining method for ore mining.After the completion of mining,a large number of ore pillars are left behind in the goaf that are difficult to recover,resulting in a significant reduction in ore recovery rate and waste of resources.In order to maximize the recovery of ore and reduce the loss rate and dilution rate of open-pit mining,a mining method of replacing ore pillars with artificial pillars was adopted in a bauxite mine in Guizhou.This mining method was first applied to underground mining of bauxite mines.Through on-site experiments,it has been demonstrated that replacing ore pillars with artificial pillars has significant effects on improving underground operation safety,improving ore recovery rate,and increasing mine economic benefits.关键词
