Hongshan Copper Blasting Parameters Optimized

Since the second stage production of Dahongshan copper, the effect of blasting operations is not satisfactory, a high rate of bulker output, low-productivity areas, a long production cycle, the waste rock roof falling, mixing stope, panel losses depleted the economic benefits be affected. Second stage need production; Should production, the key is to improve the effect of blasting, lower bulker of output, the overall production capacity of mining.Mine is the mining method used in bedding, fissures in the rock blasting of the passage of this issue, to optimize the deep hole network parameters and blasting program, by eliminating hole detonating cords, a bottom initiation, the staggered opening charge means lower bulker production rate, effectively raising panel production capacity. Panel increase production capacity to effectively shorten the cycle and timely mine filling solution mining, filling contradictions, as mine production safety to create conditions.
