摘　　要：大白阳金矿有限公司为变质岩浆热液型金矿床,目前矿山开采缓倾斜薄矿脉采用的采矿方法存在损失率、贫化率较高,顶板支护方式过于单一,工班、台班效率低,机械化程度不高的问题。采用合理的采矿方法降低采矿损失率、贫化率,提高生产能力对矿山具有重要意义。研究选用的机械化液压支柱护顶连续回采采矿法能够解决其问题,同时达到提高资源综合利用率、延长矿山服务年限的目的。矿块综合生产能力80t/d;损失率5.16%;贫化率8%。Dabaiyang Gold Mine Co.,Ltd.is a metamorphic magmatic hydrothermal type gold deposit.At present,the mining method used in mining gently inclined thin vein has the problems of high loss rate,high dilution rate,too single roof support mode,low efficiency of work team and platform team,and low mechanization degree.It is of great significance to adopt reasonable mining methods to reduce mining loss rate and dilution rate and improve production capacity.The continuous mining method with mechanized hydraulic prop can solve the problem,improve the comprehensive utilization rate of resources and extend the service life of the mine.The comprehensive production capacity of ore block is 80t/D,the loss rate is 5.16%,and the dilution rate is 8%.
