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.
