Abstract
The idea of selecting and justifying the technology options based on a rating approach to the analysis of determining factors for the safety and efficiency of mining operations is considered with regard to the class of mining systems with caving of ore and enclosing rocks. A formalized method of the scoring system has been developed, which makes it possible to quickly make decisions regarding the use of geotechnologies based on the predicted stability of mine workings, the amount of losses and dilution of ore, taking into account the value of recovered minerals. The domain of rational influence of sublevel and block caving in different mining, geological and geomechanical conditions has been determined.
