PARAMETER OPTIMIZATION OF DEEP-HOLE BLASTING WITH FIELD-MIXED EMULSION EXPLOSIVES

In Jinduicheng Open Pit, adjustment and optimization of original blasting parameters were carried out after a field mixed explosive was used. The optimization of blasting parameters such as blasting patterns, specific charge, in hole primer system and millisecond delay interval was introduced in this paper. In addition, the blasting vibration monitoring was discussed and the economical benefits produced after using the field mixed explosive and optimizing blasting parameters were calculated.
