A Pile Top RCD fitted with a 2-metre diameter drill bit is estimated to be capable of “mining” about 7 tonnes of Ore per hour. The Pile Top RCD is capable of drilling holes with inclinations from 90 o (vertical) to 72 o. The working deck has variable geometry to keep it level.
[pdf] Surface drilling rigs are hydraulic drill rigs typically designed for small to medium-scale quarries and small-sized open pit mines, suitable for rock drilling applications where rock hardness exceeds F10 in aggregate quarrying, civil engineering, road construction, open pit mining, hydropower plant construction and other blasthole drilling projects.
[pdf] In hard rock mining and quarrying, this is achieved through a controlled process of drilling and blasting. A blast hole drill rig is a specialised piece of equipment that creates a series of holes in a specific pattern, depth, and diameter across a section of rock known as a “bench.”
