This collection is dedicated to the 120 th anniversary of the national mining university (dnipro, ukraine) and designed for researchers and practitioners, students, postgraduates and university lecturers, as well as for anyone, who interested in energy conservation issues. In the case of coal fuels, as one of the main energy source, effective technologies for maintaining mining operations under difficult conditions are substantiated. The energy efficiency of coal gasification with the use of mining waste has been estimated, technical and technological means, as well as conditions for the introduction of the gas generator are proposed. In the aspect of the normalization of working conditions of miners, protective effectiveness of respiratory devices is established, taking into account the requirements of the european standard en 529: 2006. The possibility of significant energy savings is demonstrated by the introduction of electric drives with group power from a conventional dc device with storage capacity.
