CLASSSFICATION OF COAL RESERVES AT THE TYAGLIV AND LYUBELYA FIELDS OF THE SOUTH-WESTERN COAL-BEARING REGION OF THE LVIV-VOLYN BASIN BASED ON THE MAIN NATURAL INDICATORS

A geological-statistic analysis of commercial resources and the predictive coal-bearing potential fields South-Western coal region, principal promising part Lviv-Volyn Coal Basin, has been carried out. Based on detailed systematization data from prospecting exploratory-assessment works regarding depth occurrence thickness seams, ash content, sulphur content grade composition coal, Tyagliv Lyubelya re-evaluated. These characteristics have studied by discrete intervals. Re-evaluation their classification were out for every seam, mine field, region whole. In total, was performed 24 seams. By seams majority reserves at belong to group 600-900 m. The within field (6.6%) falls 900-1200 According most balance overbalance is attributed groups 0.61-0.80; 0.81-1.00 m, 0.81-1.00; 1.01-1.20; 1,21-1.50 over 1.5 Within are contained in value 50 % related medium-ash coal. At (66.4%) also corresponds — (43.1%) (53.1%) mass fraction sulphur, high-sulphur prevail, with amount low-sulphur medium-sulphur being equal ratios. prevail almost Regarding resources, prevails field. differ analogous ones industrial basin higher area distribution. increases 15-300 quality least content. brand technologic gas gas-fat fat (according Ukrainian classification) It proved that suitable coking. fat, coke-fat coke prevail. Сoke comprises a half reserves. estimated be two billion tons, which exceeds times residual basin. raw material base fields, estimation evaluation great importance developing working-out feasibility study development.
