| Abstract | Energy is fundamental to the social, economic and environmental aims at sustainable human development. Bangladesh is a developing country where the demand of energy is increasing rapidly. The country using natural gas as a major source of energy although, it has a decent reserve of coal which can play the significant role in the energy sector. Jamalganj coal field is the largest coal deposit of an area of 30 km2 and more than one billion tonnes of high volatile bituminous coals of Gondwana formation. Coal seams lies at very depth and difficult to exploitation by conventional mining technique. As a result, there is a necessity for identifying sustainable exploitation and utilization technologies. Surface and underground are mostly using coal mining technique through the world and also can be applied at Jamalganj coal field. Surface mining involves maximum extraction of coal resources but it has several long term environmental impacts. Very less percentage of coal can be extracted by underground mining but this also has several long term environmental impacts. Only operating coal field at Barapukuria, Bangladesh using underground mining and the experience is quite unfavorable. Coal Bed Methane and Underground Coal Gasification are the two coal utilization technology may also apply at Jamalganj coal field. Jamalganj field is somewhat ideal for Coal Bed Methane development because of high depth of coal seams, high coal seam thickness, symptom of gas during drilling and other geological and hydrological data. Although in Coal Bed Methane development the recovery of gas is very less compared to total coal reserve. The major environmental impact of Coal Bed Methane is water from coal seam but proper treatment before discharge can reduce the impact. Though, Underground Coal Gasification still in a developing stage and environmental impacts like water contamination is the big issue but Jamalganj coal field is favorable for Underground Coal Gasification where 35-75% in situ coal reserve can be utilized. Experience from several commercial Underground Coal Gasification projects showed Underground Coal Gasification has less environmental impacts compared to conventional mining. There is no single coal utilization technology has who does not have any impacts. But those mining technique has fewer impacts consider to others and sustainable should be select for coal utilization. |
