In this paper the results of sedimentological analysis of coal in 2010 at the lokality Petka (western coal basin Kostolac). Are presented variations of petrographic composition of coal matter (lithotypes, microlithotypes and macerals), mineral admixtures (clay, aleurite and marl) and locally occurring epigenetic mineralizations. The Kostolac Neogene Basin (Figure 1), cont aining three tick lignite beds of Pontian age[1] is one of important energetic resources of Serbia and is the bases for operating two lignite-fi...

The aim of this paper is to show the possi bilities, how effective use GIS for modelling of mineral deposits, for example of brown coal deposit Nováky. The work results - seam base model and seam thickness model, ash content and heat value of coal presented in the ArcGIS are an example of a modern appr oach to the processing of geological data. The form of presentation offered by GIS allows much more efficient deposit data processing and provides greater op portunities for planning and optimization mining activiti...

The presented paper describes artesian aquifer collector which is situated in the area of interest of the J. Sverma and Vrsany open pit mines. The area of interest is situated at the southern border of the central part of the Most Basin (previously North Bohemian Brown Coal Basin). The occurrence of severa l saturated collectors, which were created in this area in different geological peri ods (especially in the Upper Cretaceous and Miocene Period), is obstacle to the continuous extraction of coal from the beginni...

The submitted paper describes th e issues of interdeposit sa nd collector in the central part of the Most Basin in the area of J. Sverma and Vrsany open pit mines. Interdeposit sands are hydrogeologically significant collector and both mines come into contact with this collector during the coal mining. Collector of interdeposit sands is deposited between the upper bench and the main bench of coal seam. Sands create large and powerful complex of irregular layers. There are frequent changes of thickness and permeabi...
