TO THE CONCEPT OF ENVIRONMENTALLY RATIONAL EXPLOSIVE DESTRUCTION OF ROCKS DURING OPEN DEVELOPMENT OF DEPOSITS
Analyzing methods of blasting schemes and means of their initiation in the flooded massifs of Krivorozhsky deposits is carried out. The concept of detonation processes during explosion in flooded conditions is formulated. Drilling and blasting methods are detailed by streamlining blast network switching schemes. Recommendations are given on reducing the specific consumption of explosives in case of compact rock mass collapse ensuring a given crushing quality. An increase in the efficiency of drilling and blasting operations during the open development of irrigated deposits is ensured by improving the blasting rates by improving the design of well charges and the methods for initiating them.
