By lab and field experiments, the heat insulation of blasting material, the reliability of priming network and the control of blasting shock and vibration had been emphatically researched for the controlling blasting of high temperature coagulation.The paper suggests the new heat insulation materials and charge structures used under different temperatures condition of blasting objects, and presents the methods to avoid miss-fire and the measure to control the blasting shock and vibration damages to protected objects such as furnace lining, furnace body and back-up bearing.
