OPTIMIZATION OF TRANSPORT AT DEEP COAL MINES

Optimization of underground mining transport enables the growth of productivity, profitability and others economic parameters of mine company production. It enables also save electric energy, materials and to improve machinery service life. The main aim of the run transport operative control is then ensuring the greatest continuity of the haulage as possible with minimization of idle time, especially the non-technological ones, and minimization of cost. The paper presents basic principles of these profits, namely the rationalization of belt conveyer automated control systems and the system of coal valorization in a way of selective haulage and homogenisation
