3D modelling of coal seams for optimization of extraction

Underground coal mining was finished in the north-eastern region of Hungary after its operation more than two centuries, as a result economic, technical, environmental and political reasons. A fairly significant part reserve is still available to extract. With different perspective mining, considering ways utilization (such chemistry, etc.) extraction material can be cost effective. In past few years, several studies were conducted regarding possible reserve. The properties are highly mutable, therefore, comprehensive knowledge about geology indispensable. Two three-dimensional modelling seam discussed this paper, with optimal face height, expected quality products taken into consideration. Applying method presented, production fulfil desired properties, coal.
