Abstract. The features of crushing of the blasted lumpy rock mass in cone crushers of large crushing were investigated. It was found that the size of distribution of the rock mass after mechanical crushing depends not only of the width of the outlet slit but also of the fractional composition of the blasted rock mass. It is possible to control and actively influence on the process of preparation of the grinding bodies for autogenous grinding mills by managing of the parameters of the explosive ore preparation. The transfer function of the crusher has been developed. Promoting efficiency of ore mining and processing redistribution is possible due to the complex account of granulometrycal composition of the blown up ore mass and technological properties of inside-open-cast crushers of the large crushing. Estimation of the modern state of bench breaking and results attained here is executed in work. It is set that grinding bodies appear during the mechanical blown ore crushing up by the largeness -400 +100 mm. Pieces larger 400 mm by a crusher is processed mainly in a class -100 mm, thus in an equal measure in «galyu» and change. The results of the industrial experiment in conditions of Gannivske open-pit of Northern GOK were given.
Keywords: Keywords: explosion, mechanism of destruction ore preparation, crusher.
