Abstract：The basic characteristics of coal mine blasting and explosives performance requirementswere analyzed, and the blasting effect of existing mine permissible explosiveswere summarized.The detonationperformance of high-power coal mine permissible water gel explosiveswere comparedwith the existing grade 2 and grade 3coal mine permissible water gel explosives and the results showed that the detonationperformance and the blastingeffects in rock driving blasting of coal mine of high power coal mine water gel explosives were higher than that of the existinggrade 3coal mine permissible water gel explosives, and equivalentto that of the grade 2.The safety degree of flammable gaswas higher than that of the existing grade 2 and reached to the grade 3standard, whichis suit to the requirements of coal mine safety production.
