New theory for the rock mass destruction by blasting

Purpose. To develop a new theory for the rocks destruction by blasting using description of formation processes zones with various mass state around charging cavity. Methods. The rock has been developed based on use well-known elasticity laws and main provisions quasi-static-wave hypothesis about mechanism solid medium under action. models crumpling, intensive fragmentation fracturing that arise cavity in during its destruction, depending physical mechanical pro-perties mass, energy characteristics explosives pressure impact, have technique mathematical modeling. Findings. Based modeling results action medium, fracturing, which are formed char-ging monolithic or fractured mass. Originality. is realized according to stepwise patterns forming takes into account properties impact. Practical implications. When calculation radii cavity, it possible determine rational distance between blasthole charges chart, as well calculate line least resistance designing huge blasts.
