Essay

The mechanism of interaction of detonation products in detonatoin front and bottom tamping by denotation in the blast-hole was discribed in this thesis. Mathematic model of interaction of detonation products with bottom tamping was developed here. Analytic dependence for definition of bowing length of bottom tamping with detonation products and dependedce between bowing length of bottom tamping with detonation products and length of influence hydroblow in zone "tamping - bottom ob blast-hole" was received here. Methodics of calculation of effective parameters of bottom tamping was developed in this thesis.
