Tens of billion crowns were investigated after the 2^nd world war in prospecting, exploration and exploitation of Czech lignites. During this period an immense quantity of infromation was collected but not systematically evaluated. It is reality that hitherto synoptic evaluation of geological, mining, deposit and coal preparation is on the one hand non-systematic and on the other hand itsscope is rather limited. The aim of proposed project is systematic valuation of all results according to uniform criteria which would lead to obtaining of general synopsis of all lignite basins of the Czech republic both in view of their structure and development and from the viewpoints of depositis and mining. The obtained results can be applied by state administration bodies and institutions administred by them for assessing of coal resources. They can be applied also for solving of ecological problem connected with mining activity.
