Abstract

The study will show quantitative features of the latest researches performed on samples of coal from the site Negotino. In the area of the coal deposit Negotino coal quality was assessed by making more types of chemical analysis like: basic analysis, analysis of chemical composition and melting of the ash, performing petrographic analysis, grinding level of coal etc.. In order to show the results of technical analyzes of coals in more picturesque way, in the section that follows are given medium calculated values for each category of stocks, groups of categories of reserves in the entire site, using certain methods which involves the cumulative amounts of coal as well. Quality is homogeneous, petrographical determined as kutikulin - duren. Macerals are presented with xylene and poluxylene with presence of resin parts in it. Based on the values of qualitative parameters of coal it could be concluded that this is soft brown coal (lignite)
