Coppers are an important metal mineral usually found in volcanic, metamorphic rocks, occasionally in sedimentary rocks. They occur in the fault zone, rock contact zone and mineralized zone in veined and layered shape.

Drilling is an important process of copper mining. The pictures show our JK810 drilling rig that features high drilling efficiency, deep drilling depth and high-quality holes. The borehole diameters range from 90 to 165 mm and the maximum depth can reach 28 m, which meets the requirements of blasthole drilling.
