ABSTRACT
Coal industry is considered the top priority in
the economy of Ukraine, specifically in forming the index of the gross domestic product. Vertically integrated company DFEC (Donetsk Fuel and Energy Company) is the power engineering leader in Donetsk and Pridneprovs’k region. Heavy investments have been made in the modernization of mining and energy equipment to improve the efficiency of coal mining since the corporation of coal mines "Pavlogradugol" has joined DFEC. The electric drive with frequency response has become more widely used at powerful electricity generating plants (main mine fans (MMF), all types of hoisting units, belt haulage).
