摘要：

山东玲珑金矿九曲分矿在回采中遇到中厚矿体时，采用传统浅孔留矿采矿法存在一些问题，即采场顶板暴露面积过大，安全得不到保证，矿石回收率低。通过采用浅孔留矿采矿法结合中深孔爆破，能保障作业人员的安全，提高矿石回收率，缩短矿块回采周期，是传统浅孔留矿采矿法回采中厚矿体的一种新的尝试。

Abstract:

Jiuqu gold mine encounter mid-thick orebody in the mining,there are some problems while using traditional shallow hole shrinkage method,the exposed ares of stope roof is too large,security can not be guaranteed,the recovery rate of ore is low.Though select shallow hole shrinkage method combined with mid-deep hole blasting,it can protect worker’s safety,improve the recovery of ore,and shorten mining cycle of ore block.it is a new try to mining mid-thick orebody.

Key words: Mid-thick orebody, Shallow hole shrinkage method, Mid-deep blasting, Recovery of ore, Linglong gold mine
