Geomechanical Substantiation of Ore-Block Breaking Schemes Taking into Account Static Stress Field Redistribution under the Short-Delay Blasting

The features of the static stress field redistribution in a rock mass are established for schemes of blasting that form a sinusoid-shaped ore block without a free surface on the contact with caving zone. The influence exerted by caved rocks on the dimensions and location of tension zones in a broken block is estimated.
