Coal is a nonrenewable fossil fuel that is combusted and used to generate electricity. Mining techniques and combustion are both dangerous to miners and hazardous to the environment; however, coal accounts for about half of the electricity generation in the United States.

Coal mining Coal mining Choosing a mining method: The various methods of mining a coal seam can be classified under two headings, surface mining and underground mining. Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods, and the choice of which method to use in extracting a coal seam depends on many

The latest technology trends in mining indicate a compelling industry shift towards sustainability. Digital technology works harder than ever to deliver a truly modern, safe, and productive mine that addresses the increased demand for mined materials, while at the same time exceeding customer expectations and global sustainability initiatives.

CHAPTER 11 Mining Technology The Federal Coal Leasing Amendments Act of 1976 charged OTA to assess the feasibility of the use of deep-mining technology on leased areas. With the passage of the Sur-face Mining Control and Reclamation Act of 1977 congressional interest in the study of deep underground mining technology shifted
