Abstract

Explosive block blasting is one of the key operations in the technology of extraction of granite blocks in the production of natural stone facing materials. It provides both acceptable economic expenses at extraction of blocks, and the corresponding productivity of the extracting enterprise. The main requirement for such operations is to minimize the impact of blasting on cracking in the granite block.
