摘　　要：为合理开发利用地下黄金矿产资源,达到技术经济合理、回采率高、贫化率低、生产成本低的目的,针对五龙沟金矿倾斜或急倾斜薄富矿体回采提出了采矿方法的研究,通过对比分析无底柱分段崩落法与干式充填法,得出矿山采用干式充填法技术参数提升空间大、应用效果显著。干式充填法的应用有效降低了矿山回采综合损失率和贫化率,解决了以往薄矿体回采时高贫化高损失的技术难题,同时符合《黄金行业绿色矿山建设规范》中矿井废石就地充填的要求,距离绿色矿山建设更近一步。In order to rationally develop and utilize underground gold mineral resources,and achieve the purpose of reasonable technical economy,high recovery rate,low dilution rate,and low production cost,mining methods was proposed for the recovery of inclined or steeply inclined thin rich ore bodies in Wulonggou gold mine.In the study,by comparing and analyzing the sublevel caving method and the dry filling method,it was concluded that the mine adopted the dry filling method and the technical parameters had large room for improvement and significant application effect.The application of dry filling method effectively reduced the comprehensive loss rate and depletion rate of mining,and solved the technical problems of high depletion and high loss during the recovery of thin ore bodies.It also met the requirement of on-site filling for the mine waste rock in the"Gold Industry Green Mine Construction Code",which is one step closer to the construction of green mines.
