Coal Bed Methane, in short, well known as CBM, is actually methane (CH4) gas produced during formation of coal and is stored within coal beds – stratified sedimentary deposit consisting predominantly of hydrocarbon derived from plant debris of geological past through a process called coalification (details in) – occurring at considerable depth under sediment load pressure. In the past methane gas within coal was considered a hazardous one causing so many fire accidents while mining out coal from underground mines as it is highly combustible, and the miners used to adopt so many preventive measures to avoid fire accident for safe mining. In the recent past around the 1990s, a new technology is developed to extract methane gas from coal beds before mining out coal deposit. At the same time having significant heat value, methane gas, thus extracted, is utilized as a nonconventional energy resource which is otherwise very much eco-friendly. Thus the new technology played a dual purpose –...
