In order to solve the problems of low efficiency, low safety, high labor intensity and high blasting cost of jinchuan long shou mine approach, the use of on-site mixed emulsified explosive blasting technology is proposed. Through theoretical calculation and testing, the relevant parameters of mixed emulsified explosives were determined, and the evaluation formula for the rationality of the design of blasting parameters was formulated, and the preliminary calculation and judgment of the parameter design were reasonable. Through on-site tests, comparative analysis shows that: the inlet recovery adopts the on-site mixed emulsified explosive blasting technology, the charging efficiency is increased by 35.5%, the service capacity is increased by 213,000 tons / year, the blasting input is increased by 0.23m / gun, the amount of collapse is doubled, the blasting unit consumption is saved by 258,000 / year, the management of blasting materials and manual operation safety are higher, and the labor intensity is lower.
