Mathematical Model to the Calculation of the Parameters of Vertical Ejection Charges
There are discussed the models of calculation parameters of vertical cylindrical ejection charges. These include vertical cylindrical and slotted charges. In both cases, for calculation of the charge, the hydroimpulsive explosion model in soft soil is used. Particular attention is given to slotted charges. There is shown the possibility of practical realization of such a form of charges with the help of the system of deep-hole charges. For this case also received design formula that unites the entire set of parameters of drilling and blasting.
