摘　　要：罗卜岭铜钼矿位于福建省上杭县紫金山矿区的正东侧,主矿体上部及部分矿体内部广泛分布着厚大的破碎带(Ⅴ/Ⅳ类岩组,RQD<50%)。本次研究工作着重利用3Dmine三维地质软件,借鉴三维建模及矿体品位估值的原理,用RQD值代替矿体品位对罗卜岭铜钼矿进行了RQD三维工程地质建模,量化了矿体及围岩任意位置的破碎情况,对后期的矿体开采和井巷建设具有较好的指导意义:明确了破碎带与矿体空间位置关系并指明150~100m标高适宜作为首采中段。Luoboling Cu-Mo deposit is located in the east of Zijinshan copper mine.Thick crush zones（Type V/IV rock groups,RQD50%）are widely distributed in the upper part of the main orebody and inside some other orebodies.By applying geological software 3 Dmine,based on principles of the three-dimensional modeling and orebody grade estimation,this paper used RQD values in the RQD 3 Dengineering geological modelling instead of orebody grade,and quantified the crush situation at any location of orebody and wall rock.The results provided guidance for exploitation of orebody and construction of laneway.The spatial relation between crush zones and orebodies was thus determined,and the elevation of 150-100 m was verified as the initial mining level.
