Coal Mining
The environmental aspects of mining have received little analysis. U.S. coals vary in moisture content (2 to 40%), sulfur content (0.2 to 8%) and ash content (5 to 40%). The energy content varies from lignite to sub-bituminous to bituminous coal. The ORNL-RFF study looks at two levels of sulfur content (0.7% and 2.1%).

Smart mining: Extracting the power of AI
Smart mining: Extracting the power of AI. With one-third of its underground land mass covered with coal deposits, coal mining is the lifeblood of China's Shanxi province, providing half of its revenue and 1 in 20 jobs. However, the industry is traditionally dirty, dangerous, and inefficient. Now that's starting to change with the AI-powered ...
