Analysis of coal quality in a function of selection level for mining at the open pit Gacko

Abstract

This work analyzes the quality of coal in the function level selection for exploitation. A detailed analysis was carried out for the main coal seam, the first floor seam, the second floor seam and the overlying coal series of the coal deposit Gacko of 0.5 and 1 m. The analysis was carried out within the Strategy of mining-technological opening, development, optimization and maintenance the continuity of coal production with development the Feasibility Study of introducing a dry separation method in order to determine the amount and quality of coal for TPP Gacko. The analysis included the effects of natural and technological factors on participation the seam overburden in the run-of-mine coal as well as a degree of overburden impact on the quality of run-of-mine coal.
