Abstract:
The results of existing studies of explosive methods for preparing rock for excavation allow only an approximate determination of the size of the rock pieces during the explosion, as well as the specific consumption of explosives. The research is aimed at developing a methodology for calculating the technological parameters of blasting operations, accessible to the technical personnel of the quarry. To achieve this goal, the expediency of using a triangular grid of wells is justified, which makes it possible to reduce areas of undisturbed rock compared with a rectangular grid. When studying the stress state of the rock during an explosion, dynamic strength is taken into account. The complexity of determining the rupture area makes it difficult to determine the specific consumption of explosives. A hyperbolic law has been established for changing the fracture area of a rock depending on the size of an individual piece of rock. A method for determining the energy consumption for the formation of an explosion in one well is proposed, taking into account the dynamic tensile strength, as well as the hyperbolic pattern of changes in the fracture area of rock pieces. The developed method for determining energy consumption allows mining engineers to more reasonably approach the purpose of the specific consumption of explosives. The method takes into account the size of a piece of rock corresponding to the involvement of the working body of the excavation equipment that is available at the quarry under consideration.
