In the medium-deep hole blasting, low-sensitivity explosives such as granular ammonium explosives should be detonated with a primer.
Initiation kits commonly used explosive rock roll # 2 packs of tied up, there is a the RDX and TNT or RDX explosive detonation kits like composition (or from bomb), the former is used for small and medium Mines, the latter are mostly used for deep hole blasting in large open pit mines.
When deep-hole blasting in open pit mines, the primer is generally placed at the bottom of the hole, and the detonation wave is detonated in the opposite direction to the hole at the bottom of the hole. When the blasthole passes through several different rock formations, the primer should be placed in the rock layer that is most difficult to blast. In the specific case of using low-sensitivity slurry explosives, a common detonating tube is used to detonate, and in order to prevent the explosive from being crushed, the detonation kit should be placed on the top to detonate.
In deep-hole blasting in open pit mines, double-packs are sometimes used to detonate, that is, a drug pack is placed at the top and bottom, which is beneficial to improve the blasting quality of the rock.
