RESULTS OF GEOLOGICAL STUDIES ON BLACK COAL DEPOSITS IN THE CENTRAL COAL REGION, LUBLIN COAL BASIN

Summary
The studies carried out by Polish geologists for over forty years in the eastern Lublin region resulted in discovery and documentation of a new coal basin, called as Lublin Coal Basin. The Central Coal Region, representing central part of this basin, is best known from geological point of view. The Lublin Beds, the major productive series in this area, are dated at the Westphalian. Tectonic structure of the Central Coal Region is shown in the form of a structural model, constructed on the basis of borehole data and results of geophysical surveys. An asymmetric basin with NW - SE oriented axis is the major structural element of this area. North-eastern limb of the syncline appears very flat, with strata dipping at the angle of 2-4° to south-west. The south-western limb is steeper, with angle of dip of strata up to 20°. This simple structural image is complicated by numerous faults marked throughout the area. Two structural models of the deposit may be differentiated. One of them (Fig. 2) originated at the stage of recognition of the deposit in the category C2, and the other (Fig. 3) - after the end of recognition of the deposit in the category C1.
