Use of coal mine methane in coal dryers, and Using coal mine methane to heat mine ventilation air. Based on the principle/mechanism for end-use of coal mine methane, most of these technical options can be categorised into: (1) methane oxidation (combustion), and (2) chemical feedstocks.
released during coal mining. As part of the President’s Climate Change Action Plan, established in 1993, coal-mine oper-ators are being encouraged to recover and use coal-bed methane for energy. Methane Migration In some areas, methane migration may have contaminated ground-water sources, and methane may have migrated into residential neighborhoods.
