摘要
铜辉矿业在开采破碎薄至中厚矿体采用了无底柱浅孔留矿法采准与分段崩落法落矿联合采矿方法,通过该采矿方法的试验,安全有效的提高了采场的回采率,降低了采矿成本,提高了矿山的经济效益,推广应用前景广泛。
Joint mining methods including non-pillar shallow hole shrinkage method and the sublevel caving method is used in this paper, through the experiment, the recovery rate of stope are improved effectively, mining costs is reduced and the economic benefits of the mine are increased to promote a broad application prospects.
