Communication

Summary: Summary By the method of experimental mining with linear increased burden, it will be determined optimum kind of explosive and optimum parameters for definite kind of rock. In the manner it will be incrased effect of mining accompanied with smaller drilling and specific charge of explosive. Getting material and making of underground areas will be less expensive. On the base of measurments of frequency of the ground cuased by mining it will be determined the safe quantity of exsplosive charge near settlement.

Keywords: Optimal blasting magnitudes, underground blasting, ground oscillation velocity, allowed charge quantity

Research goals: Intention of the suggested examinations is to determine optimum kind of the explosive and optimum parameters for mining in definite kind of rock. In the case of mining with optimum parameters it is incrased effect of mining and decreased drilling and specific charge of the exsplosive and accompanied with optimum distribution of particle size blasted rock. The cost of mining is less. That is great contribution to the science of crushing with explosive energy.
