NEW METHOD OF BLASTING IN FIELD DEVELOPMENT WITH APPLICATION OF PHYSICAL-CHEMICAL GEOTECHNOLOGIES

In the article the method of underground directional shaking of blasting with the aim of increasing the efficiency of leaching in systems development using physico-chemical Geotechnology. The possibility of formation of charge of any diameter and energy through play and the use of the directional effect of the explosion of the beam at the same time blow up of closely spaced borehole charges. Thus in the array there is a significant disclosure and the formation of new microcracks. In practical terms, this makes possible the use of regular drilling equipment in mine drilling normal, that is, in straitened conditions of underground mining new technological implementation of drilling and blasting.

Keywords

Blast, explosive, structure of rock, charge design, camouflet-shaking blasting, bundles of closely spaced horizontal wells, leaching.
