Using the rock mechanics and blasting parameters in a certain field engineering, the numerical calculation model of cylindrical charge and segmented blasting was built, and the stress features and velocity laws in the shallow-hole blasting were researched. The factors of gravity for the medium and sub-blasting effect were considered. The results show that the effective stresses of geometry shape diversification are maximum, and the maximum principal stresses of the nearest station from the explosion source are maximum. The computation velocit...
