Minimization of energy intensity of mechanized underground coal mining

S.A. Prokopenko

The article discusses the areas and promising solutions of power generation in underground mines based on alternative energy sources. The author describes the design of a roof support unit, which allows the conversion of caved rock energy into electric power. The design is proposed of a roof support unit with two power units providing broader use of the gravitational potential of moving rock materials.
