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.
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.
