Full Description
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, specific attention is paid to progressive and innovational technologies in the coal industry of leading countries.
Widening the range of mining-geological conditions under which drivage and maintenance of mining activities are carried out, requires application of new constructive decisions. Hence, this collection of papers is focusing on the following topics: results of new equipment introduction; experiments on mutual interaction of roof support elements, protective construction and near-the-contour rock massif; analytical and calculation methods of geomechanical tasks solution; development of gas hydrates and technologies of underground coal gasification; studies on environment protection; economic aspects; management and marketing in mining production, and other important aspects of mineral deposits exploitation.
