试析中深孔高分段空场法开采急倾斜薄矿体

Analysis of High Sublevel deep inclined thin ore mining law

针对浅孔留矿法在急倾斜薄矿体中的应用局限,立足于实践经验,分析急倾斜薄矿体采矿过程中存在的主要问题,并以邱村金矿矿区开采作业工程为例,从矿块布置及采切工程布置、开采范围确定、爆破参数的确定、落矿处理、空区处理等方面介绍中深孔高分段空场法在急倾斜薄矿体中的应用,解决采矿效率、安全性低等问题。

For shallow hole Shrinkage Method confined inclined thin ore body, based on practical experience, analysis steeply inclined thin ore mining major problems exist in the process, and Qiu village gold mine of mining operations engineering, for example, from nugget layout and cut mining engineering arrangement of mining OK, OK, blasting parameters, aspects falling ore processing, presentation Gob processing applicatxons deep high Sublevel in steep inclined thin ore body, mining efficiency to solve, and low security.
