Coal Production - an overview | ScienceDirect Topics

Much of the coal production from 2007 to 2011 is from surface coal mines, which has grown 10–12% in contrast to underground coal mines, which has grown only about 2% during the same period (USEIA, 2012). And there are currently a limited number of coal mine gas recovery and CMM-to-power projects in existence or planned coal mines.Introduction to Coal Mine Drainage - GARDGuide,Introduction to Coal Mine Drainage C2.1 Introduction C2.2.

After the coal is mined the machine is dismantled and relocated to another section of the mine allowing the roof to collapse behind. Advances in technology have led to the introduction of automated longwall mining systems.
