焦家金矿望儿山分矿高效采矿方法研究

Research of high-efficient mining method in Wangershan branch of Jiaojia Gold Mine

高效采矿方法的研究一直是有色矿业发展的研究方向,随着黄金价格的下降,降本增效成为矿山发展的重要途径,而创新一种高效的采矿方法,提高出矿效率,降低采矿成本势在必行。基于望儿山分矿现有的生产技术条件,结合现阶段进行的中深孔采矿方法试验,决定研究推广一种高效的中深孔采矿方法,此方法大大提高了现有的生产效率,降低了万吨采掘比,为矿山的降本增效工作提供了极大的帮助。

The high-efficient mining method has been the research direction of nonferrous mining industry development.Because of the gold price going down,reducing cost and increasing efficiency has become very important for mine development,and creating an efficient mining method for improving mining efficiency and reducing cost become imperative.In Wangershan branch,based on existing production condition,and combined with medium-length hole mining method test at present,it was decided to promote an efficient mining method.This research has greatly improved the existing production efficiency and reduced mining ratio.It provided a great help for mine reducing cost and increasing efficiency.
