Methodical bases of the quality control and management of commodity ore in the process of breaking dipping ore bodies of low power
YU. P. GALCHENKO, A.S. Shuklin

The development of methods for effective monitoring and control of quality indicators for blasting ore is one of the main directions of modernization of mining technologies. Analysis of experience in the development of flat and inclined vein deposits showed that, as in the case of steeply dipping deposits, real prospects for improving the efficiency of mining operations are associated with a radical change in the principles of systems development. Made in this area of research allowed to recommend specific options geotechnologies for considered conditions, based on the use of wells of small diameter for breaking ore from sublevel horizontal workings with the gross elements and
selective vzryvozashchity repulsed the rock mass. It justifies a whole new feature the explosion for additional crushing of ore at the expense of the kinetic energy of its garbage in the extraction slit. Based on the goals of improving the qualitative indicators of development lived solved a number of scientific and methodical tasks, ensuring purposeful control the distribution of energy of the explosion in the array when breaking in terms of the clamp.
Keywords: methodology, gentle veins, election recess, blasting, selective excavation, cutting of the host rocks, garbage explosion, direction, additional energy, division, ore mass, species mass, vzryvsklady, cleaning ore development system.
