Optimal parameters of borehole charges

Experimental data on full-scale borehole-charge explosions are outlined, with a view to establishing the optimal relation between the basic sinkhole parameters and the charge elongation coefficient. It is shown that the results of full-scale explosion are in good agreement with laboratory data.Krasnodar. Translated from Fizika Goreniya i Vzryva, Vol. 28, No. 4, pp. 127–129, July–August, 1992.
