Abstract

With the application of contour blasting’s, we manage to make the cutting of the rock mass in the designed line, forming safe benches and slopes, which can resist for a very long time without collapsing and changing their shape. The choice of optimal parameters of the geometry of contour drillings and production drillings enables very good cutting of the rock mass and enables us to have a very good fragmentation of the rock mass, which enables us to make loading and haulage of the rock without any problems. As the optimal parameters of contour drillings and production drillings, for our case are ac= 0.75 [m], bc = 2.8 [m], dhc= 76 [mm], a=2.8 [m], b = 2.8 [m], W = 2.8 [m] dhe dh = 89 [mm].
