Justification of new opportunities for the use of the gravitational energy of the earth in underground ore mining with convergent geotechnologies

The paper describes R&D project results on justification of a new approach to the induced caving ore using convergent geotechnologies. In this case, optimized conditions are created for self-caving in block-structure rock mass based evaluated limiting exposed span using, among other things, Mathews–Potvin stability graph. design solutions include formation density discontinuity form vertical slit mass, as well different inclinations sides manmade separation and outlining backfill frames. authors calculate potential gravitational energy Earth, which is accumulated within dome natural equilibrium generated course mining.The appreciate participation Senior Lecturer from NUST MISIS’ College Mining N.
