| Summary: | A number of coal gasification technologies are currently available or under various stages of development. One technology “Underground coal gasification (UCG)” is receiving renewed interest around the world. In this paper is provided the analysis of relevant processes during UCG. The laboratory equipment is described. Since experiments have long time response, partial automation has been realised. The structure of monitoring and control system is shown. Analysed are some results of measured data for oxidizing by air. Also, the influence of temperature on the structure of syngas is analysed. In light of the experimental results, potential performance of UCG in Slovak coal seam conditions is discussed.
