Abstract
The stability of the slopes is of the utmost importance during the exploitation works in surface mines and during the opening of roads, because this directly affects the results of the works and safety. Achieving the highest possible stability of the slopes is done using contour blastings, to make the cutting of the massive that is mined. But in order to achieve the best results in cutting the massive that is being mined, milliseconds delays should be used, in order to create free face before each subsequent blasthole, in this case the impact of drillings of the preliminary rows on behind them will reduced. With the application of milliseconds delays 17 [ms] between drillings in the row and 67 [ms] between rows, the impact of blastholes of the front rows will be very small or no impact at all on behind them, making it possible to form benches and slopes safe and without cracks. This enables us to have safe mining work and safe driving on the road.
