THE USE OF MODERN INITIATION WAYS AND HOLE CHARGES DESIGN FOR THE ROCKS GRINDING QUALITY INCREASE

V.I. Komaschenko

The resource – saving methods of the step breaking using the complex detonation processes of the hole charges and the explosive composition: the universal channel striker construction which combines the detonative charge with the hollow cavity and new charges construction with the longitude cavities were elaborated. The most effective explosion schemes are suggested the typical hole charge construction with the universal channel striker is presented. The technological parameters of the iron quartzite explosive breaking providing the minimal output of the mobile dust particles being performed in stages help to achieve the aim. The hole charge constructions with the air in the form of the chains from cushions the synthetic polyethylene capacities in the polyethylene hose dm 200mm being mounted in the hole on the step bottom level are developed.
