Abstract

Based on damage mechanics theory, a mechanical model for rock blasting was established considering of the rock heterogeneity, in which rock blasting was considered as two consecutive stages: the dynamic stage caused by the stress wave and the static stage caused by explosion gas pressure. The cracks evolution of cutting seam cartridge blasting under different in-situ stress conditions was numerically simulated. The numerical results indicate that the blasting cracks mainly initiate around the cutting seam and propagate along the cutting seam direction. For different in-situ stress fields, the crack propagation will be suppressed when the maximum in-situ stress direction is perpendicular to the cutting seam direction, while promoted when the maximum in-situ stress direction is parallel to the cutting seam direction. The crack direction is controlled by the direction of cutting seam and maximum in-situ stress, while the crack propagation is suppressed by the in-situ stress field.
