The data refer to the period between 1978 and 1990 when most intensive and systematic exploration took place. In more than 225 years of activity, the brown coal mine Laško had many longer or shorter interruptions and oscillations of coal production. The coal from the Laško brown coal mine has always been known to be of the highest quality among the Slovenian brown coals, mostly due to its high calorific value (ARB) and low sulphur content. Because of its quality, coal sales on the domestic market were never poor. Because of the energy crisis at the beginning of the 1970-ies, the decision was made to close the mine. The mine closure took a long period in spite of the mine company plans and activities forits restructure, so that the brown coal from Laško was mined until the middle of 1992. The ultimate mine closure reasons were technical and economic conditions of underground mining. After the final decision for closing the mine was made, the production was suspended, and extended underground mine closure and surface reclamation works were carried out. ER -
