Mathematic simulation for the rock mass destruction by blasting
(2021)
Modeling of rock mass destruction by explosion allowed to obtain mathematical models of the formation of crushing zones, intensive grinding and crack formation, which are formed around the charging cavity in the rock mass ...
Examination of density and detonation velocity of emulsion explosives
(2022)
Purpose. To develop a method for calculating the change in the density of emulsion explosives (EE) along the length of the charge column under the action of hydrostatic pressure at different angles of inclination of the ...
Using the methods to calculate parameters of drilling and blasting operations for emulsion explosives
(2023)
Mathematical modelling of rock mass breaking using blasting has been applied to obtain formulas for the calculation of crush zone radii, intensive fragmentation, and crack formation around the charging cavity in the ...
Environmental assessment of the use of emulsion explosives in underground iron ore mining
(2024)
The article provides a comprehensive analysis of using TNT-free explosives (E) in the iron ore mining sector in Ukraine. It delves into the development and application of a specific type of emulsion explosive known as ...
