CONTROL AND APPLICATION OF FRAGMENTAL RADIUS AFTER GRANITE''S DRILING BLASTING UNDER WATER
花岗岩体水下钻孔爆破碎径的控制与应用

In order to solve the practical problems in cngineering blasting,based on the physico-mechanicsmeaning of similar parameters in granite blasting and the principle of energy criterion,the fragmentingproperties of drilling blasting in granite under water are studied, and the parameters of engineering blasting are designed and selected in this paper.Further more,the successful practical application in engineering is obtained.
