Rock massif observation from underground coal gasification point of view

Abstract

The Underground coal gasification (UCG) of the coal seams is determined by suitable geological structure of the area. The assumption of the qualitative changes of the rock massif can be also enabled by application of geophysical methods (electric resisting methods and geoelectric tomography). This article shows the example of evaluating possibilities of realization of the underground coal gasification in the area of the Upper Nitra Coal Basin in Cíge¾ and Nováky deposits, and recommend the needs of cooperation among geological, geotechnical and geophysical researchers.
