Estimation of ecological-economic investment of efficiency into new technologies of thermal coal preparation on modern heat power-stations

The factors defining efficiency of large-scale use of Kansk-Achinsk coals in power engineering of Russia are considered. Designed methods toolkit of a system estimation of ecological-economic efficiency estimate rational scales ofmultiplicating and defin priority regions for the technologies development of preliminary thermal preparation of Kansk-Achinsk coals for long-term prospecting.
