New trends of mineral deposits mining in the world consist of intensifying and concentration of mining operations. This is achieved with the help of new technical equipment that is more reliable, having greater service life and more available power. Consideration is given to quantity reduction of stopes and development workings together with their geometrical dimensions growth; also length increase of longwalls and extraction panels is examined. Innovative technologies helping to increase technical-economic indices, extraction volume, working efficiency and safety rules are presented in the...

In the last decades coal production capacity has increased rapidly and its quality, power and the reliability of equipment has steadily improved. Moreover, stability of production processes can be controlled better. In connection with that, unification of scientific schools focusing on "Mining of deposits" is an integral trend from the viewpoint of technical and technological policy.
This collection of papers represents the scientific and technical achievements with regard to mineral deposits mining intensification based on effective use of modern techniques and technologies. Also,...
