Mine seals are used in underground coal mines throughout the United States to isolate abandoned mining areas from the active mine workings. The objective of adding inert gas to a sealed mine area is to quickly reduce the oxygen concentration in the sealed area to a level that will not support combustion. Under a program created by the Mine Improvement and New Emergency Response Act of 2006 (MINER Act), the National Institute for Occupational Safety and Health awarded a contract to Connecticut firm On Site Gas Systems to design and construct a novel nitrogen generation plant that operates in the underground environment. The purpose was to create a reliable in-mine mobile plant that would extract N2 gas from the mine atmosphere and use the gas to create and maintain a safe sealed mine area.
