Abstract

The general direction of development of mining works in the Muruntau open pit is to increase its development depth to 700 m and more with the expansion of the area of application of cyclic-flow technological schemes of development with the use of steep-slope conveyors, which significantly tightens the requirements to the size of the transported material. In view of this, the main concept of improving the technology of blasting in the quarry is the intensification of blasting processes and increasing the specific weight of the blasting method of crushing as the cheapest and most technologically advanced.
