Abstract
The main factors have been examined and methodical approaches in estimation of technical productivity of quarry screw malling shearers are proposed. The results of simulation of technical productivity of a shearer according to proposed technique and equation have been presented on the example of development of Dzheroy-Dardar'yinskoe deposit of phosphorites using this Shearer.
