Abstract
The paper presents the design of a combined mining system that ensures favourable mining conditions for the development of ore reserves in conditions of unstable host rocks. The technology provides targeted transformation of the rock mass structure through the use of various technological solutions, which contribute to increasing the productivity of stoping, creation of a enclosing layer with increased strength to enable application of the high-performance room-and-pillar mining system. This approach allows efficient extraction of reserves located within an unstable host rock mass. Application of the developed option of the combined room-and-pillar system results in improved mining conditions and enhanced efficiency of stoping. The idea that when each subsequent section of the deposit located in ever more challenging conditions and having ever lower ore grades is introduced into mining, it is necessary to carry out a targeted technogenic transformation of the rock mass, i.e. to create favourable mining, geological, engineering and geomechanical conditions of its operation, is an important scientific and practical task of mining technology
