摘　　要：以国内某金矿地下开采方法为例,结合该矿山的开采技术条件以及开采现状,对该矿浅孔留矿法的采场顶柱进行回收工艺研究。在分析采场顶柱技术、安全影响因素的基础上,设计以人工砼顶柱作为保安矿柱进行顶柱回收。技术经济分析表明,使用该方案对浅孔留矿法采场顶柱进行回收,技术可行,能获得较好的经济效益,可充分利用资源和提高开采回收率。Taking the underground mining method of a gold mine in China as example,combined with the mining technical conditions and mining status of the mine,the stope top pillar mining technology of shallow hole shrinkage method in the mine was studied.Based on the analysis of the influencing factors of stope top pillar technology and safety,the artificial top concrete pillar was designed as the security pillar to recover the top pillar.Technical and economic analysis shows that using this scheme to recover the stope top pillar of shallow hole shrinkage method is technically feasible and can obtain better economic benefit,make full use of resources and improve the mining recovery rate.
