- Abstract
The economical impact ant the worldwide population increase is moderated by the decrease of the demand of electric energy, as an effect of the structural changes of the economy, the technical progress and the increase of the price of energy. The global market for energy shall be dominated by combustible fuels, their proportion being considered to reach almost 80% of the demand in 2030. Oil, natural and schist gases shall remain the main energetic resource, representing approximately 35% of the demand, the percentage of coal being 30%. By 2030, almost two thirds of the increase of coal supplies will be brought from Asia. As the single and most important player on the energy production market by burning black coal, Hunedoara Energetic Complex - HEC, through its Mining Branch, has the task of increasing the efficiency and improve the underground coal extraction technology, in order to situate the render the complex coal extraction process economically efficient considering the characteristics and rules of a free market, as well as the requirements demanded by labour safety conditions and ore protection. The paper brings forward, considering the undermined front coal exploitation method the proportion of which reaches 65% for the realisation of the total production on the entire coal basin, some of the technical mechanisation solutions of the main operations which define a complete coal face cycle.
