APPLICATION OF HOLE BY HOLE INITIATION TECHNIQUE FOR DEEP HOLES BLASTING IN JINDUICHENG OPEN-PIT MINE

Mining blasting inevitably produces endangerment of earthquake wave, air strict wave, flying stones etc, which can endanger persons, equipments, buildings nearby or stope-boundary, therefore take effective measures to ensure safety in blasting. Through provide application of hole by hole initiation for deep holes blasting and blasting domain planning, blasting effect is being analyzed, it is effective that Orica's high-accuracy detonators are in achieving hole by hole initiation, improving blasting quality and reduction in blasting vibration. Economic benefits are apparent.
