Technological aspects of selective breaking and mining thin ore bodies in the mines of "PPGHO"
Downward recess horizontal layers with goaf, used in mines Streltsovsky ore field, allowing work on the structure of complex ore bodies. However, with increasing depth of mining thickness of ore bodies decreases. In developing the thin ore bodies using wide- dilution technique increases chipped and reduced quality of salable ore. To improve the efficiency of selective mining thin ore bodies, reduce dilution indicators needed improvement and rationalization of elements of sewage extraction and commissioning uzkozahvatnyh Scooptrams. Depending on the conditions of working thin ore bodies proposed complexes cleaning selective mining mechanization, providing several options for combination drilling and LHD equipment. Their comparison to the minimum possible width condition generation, performance and cost of the equipment. The results of technical and economic calculations. Shows the change in the cost of 1 kg of uranium, depending on its content in geological reserves, power orebodies applied systems development and recommended equipment.
