Abstract: In order to improving the power of JWL-type III high temperature sensitive emulsion explosive,the flowing measures are adopted,they are adding pipeline premixer,adjusting the content of sodium nitrate and water of the formula,adjusting the technical parameters of oil-water phase temperature,using integration of complex oil phase material.The engineering blasting results show that the power of JWL-type III high temperature sensitive emulsion explosive is improved effectively,the explosive consumption and blasting cost are reduced.

Key words: JWL-type III high temperature sensitive emulsion explosive, Formula adjustment, Blasting cost
