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