Abstract
Proposed a method for optimizing the parameters of drilling and blasting operations, considering the physical and technical properties of rocks within the blasted block, in order to improve the quality of the blasting quarries with a complex geological structure. Described the ground-penetrating radar method is with the application of the "Oko-2" series of the development of the group of companies "LOGIS-GEOTECH" with antenna blocks AB-90 with a depth of sounding up to 16 m. and a resolution of 0.5 m. in depth and AB-150 with a sounding depth of 12 m. and resolving ability of 0.35 m. in depth. The results of laboratory experiments carried out on blasting blocks with various strength properties are presented, confirming the improvement in the quality of crushing of rock samples by explosion of charges with variable decelerations and location, depending on the strength properties of the samples, relative to charge explosions with unchanged parameters. This will ensure a better crushing of the blasted rock mass.
