| Abstract: | The model test investigations of directed fracture blasting have been carried out by using the super dynamic measuring system and the 3-dimensional laser holographic dynamic photoelastic instrument. The dynamic stress field and the mechanism of the directed fracture blasting are analyzed. The practical directed fracture blasting method and the corresponding technology are optimized. Working practices in rock drifts show that the selected slit-charge directed fracture blasting method is feasible,it opens up broad prospects for improving the existing smooth blasting technique. |
