不稳固矿岩振动出矿崩落法的试验研究

AN EXPERIMENTAL STUDY ON BLOCK CAVING WITH VIBRATING ORE REMOVAL IN UNSTABLE ORE AND ROCK

南京九华山铜矿主矿体由于矿岩不稳固，不能采用设计的留矿法开采，长沙矿山研究院根据矿山的实际条件，经反复研究，综合国内行之有效的实用技术，提出了振动出矿崩落法方案，经试验研究取得成功。本文介绍了振动出矿崩落法采矿工艺试验研究情况。

Due to unstable ore and rock of main orebody in Jiuhuashan copper mine inNanjing,the designed shrinkage stoping can not be used.According to the practical condi-tions of the mine, technicians from Changsha lnstitute of Mining Research conducted re-peat studies,and established the scheme of the block caving with vibrating ore removalcombined with effective and practicaI techniques in China,with success in the experimentalstudy.This paper presents the experimental study of this technology.
