摘要
介绍了北缘矿体采矿方法演变 ,对分段留矿嗣后充填法作出初步评价 ,肯定了矿体上盘不稳固花岗闪长斑岩长锚索加固是可行的 ,全尾单管胶固充填新工艺在丰山铜矿北缘矿带推广应用是成功的 。
This paper expounds mining method of north edge orebody.The sublevel shrinkage with post mining filling is evaluated,and it is affirmed that using long cable to support unstable corcovadite on orebody upper plate.Total tailing single line cementing filling is used successfly in Fengshan Copper Mine,and good economic benefit is obtained.
