Abstract:
It is known that short-delay detonation should help reduce the cost of explosives, reduce the seismic impact on objects, minimize destruction deep into the massif, as well as the formation of rock mass collapse. The purpose of the article is to develop a methodology for determining the explosion energy based on integrating the dynamic tensile strength of the rock over the depth of the well. To achieve this goal, a calculation scheme has been developed for determining the energy consumption for destruction without deceleration and pre-destruction, as well as with pre-destruction and deceleration for a rectangular grid consisting of four wells. The causes of incomplete crushing of the rock during a rectangular grid and a massive explosion are revealed, and the main provisions for eliminating this disadvantage due to pre-destruction during deceleration are indicated. The size of the savings of explosives due to pre-destruction during short-range detonation has been determined. The developed technique allows a more reasonable approach to the purpose of the specific consumption of explosives. The methodology takes into account the effect of the fracture area of a piece of rock on the energy consumption of blasting operations. The technique has been positively tested at the Kekura gold deposit in the Chukotka Autonomous Region.
