Model of environmental life cycle assessment for coal
Significant negative environmental aspects of hard coal mining include methane emissions into the atmosphere mining waste and drainage water (Kugiel 2010). The methane hazard is one of natural hazards accompanying underground operations in the Polish hard coal mining industry (Krause and Krzemień 2013 Krause and Smoliński 2013).

Oil Shale Deposits Maps Geology Resources
Oil shales range widely in organic content and oil yield. Commercial grades of oil shale as determined by their yield of shale oil ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands.
