BlastHole Drilling Introduction
Jun 04, 2019 · The optimum pull down depends on rock strength and bit size. For example, in a typical coal mine with a rock strength of 10 000 psi (69 MPa), the optimum pull down is about 67 kN (15 000 lb ). The compressor output should be matched with the drill pipe and bit to give an uphole air velocity of 3040 m/s ( ft/min).
Noncoal/Industrial Minerals Mining
Noncoal/Industrial Minerals Mining. 'Noncoal' is any mined commodity that isn't coal or peat. These minerals are also referred to as "nonfuel minerals" or "industrial minerals". The most common noncoal mines in Pennsylvania produce "aggregate" (hard granular material used in concrete, mortar, plaster, blacktop).
