SUBSTANTIATION OF RATIONAL PARAMETERS OF THE EXPLOSIVE BREAKOUT TECHNOLOGY IN A STRUCTURAL BLOCK ARRAY

English abstract

The idea of this work is to choose a technological scheme of drilling and blast-ing, which provides spacer pinching of the separateness released along the natural surfaces of the weakening of the ore massif and thereby increases the duration and efficiency of explosive crushing of the structural block array as a whole, the object of research of which is the technological process of drilling and blasting of ore dur-ing underground mining of powerful and medium-capacity deposits represented by strong ores. The authors in this robot investigated the parameters of fracturing and structural blockiness of the ore-containing massif of the Yubileynoye deposit and conducted experimental work to establish the quality of breaking of the fractured structural block ore array, and also developed recommendations for choosing a rational scheme and calculating the parameters of drilling and blasting operations in a struc-turally heterogeneous array.
