dc.description.abstract | The methods for the determination of stress state in rock mass using the energy of explosion are substantiated. The industrial tests are performed with a view to sizing zones of squeezing and radial fracturing in mines of Priargunsky Mining and Chemical Works. It is found that the fracturing zone radius decreases and the squeezing zone diameter increases with the grater depth of mining operations. The theoretical formulas for calculating stresses depending on sizes of squeezing and fracturing zones, physical and mechanical properties of rocks and detonation characteristics of explosives are obtained | ru |
