Sandvik longhole drill rigs for underground drilling and bolting are engineered to minimize ore loss and dilution by drilling straight and accurate holes up to 54 meters 177 feet in length. We offer a comprehensive range of boom types, hydraulic rock drills, carrier size classes and tool selections to ensure optimum hole quality every time.
It has been adopted for drilling upto a depth of 3000 m and hole diameter upto 200 mm. Drilling upto such large depths is not required in coal mining areas where the maximum drilling depth is upto 1000 m, as coal mines are rarely deeper than that.
The type of rock drill used in mining drilling is generally determined by the hole diameter required and the mechanical properties, principally hardness, of the rock. A top hammer is commonly employed for drilling of holes less than 125 mm in diameter in all but the hardest rock, although a rotary cutting method may instead be used for soft rock.
