Mine Master made self-propelled drilling and bolting rigs designed for underground mining

Abstract

Underground exploitation (mining) of useful minerals consists of three main stages, with the entire process starting with winning through loading and finishing with construction of the lining. Minerals are mined using explosives or mechanically by machines which are called combined cutter-loaders (cutting and loading).When rocks are hard to mine or they are abrasive, now only methods using explosives can be used as a factor destroying rock cohesion, and room or room-pillar or gallery technology may be applied as well. The application of explosives requires holes to be drilled of various length and diameter oriented spatially, manually, or mechanically. Then, self-propelled drilling rigs, loaders, self-propelled bolting rigs and haulage vehicles are applied most often in these circumstances. A set of these machines constitutes a complex for the exploitation of mined- -hard and abrasive minerals, though the machines may be used with other types of rock as well. One such example are the machines made by Mine Master Sp. z o.o. designed for mining metal ores like copper, zinc, nickel ores, also rock-salts and potassium salts and bituminous shale.
