ABSTRACT

Coal, Oil and Natural gas account for 30%, 31% and 2% respectively of the
world’s total energy. In India, coal based energy is the main source of energy and
its energy demand is increasing at the rate of 9% per year. The supply on the other
hand is lagging behind. If this trend continuous, it is estimated that by the year
2022, India would be required to spend Rs. 860 billion per year to meet its energy
demand.
World attention has recently started shifting towards methane, which can be
exploited from the coal bed. Coal mining accounts for an estimated 10% of all
methane emissions. Methane, a potent Green House gas (GHG) is released into the
atmosphere during and after mining of coal, contributing to climatic changes. The
effects of air pollution due to GHGs have recently sparked a new wave of
consciousness from the international arena. Climatic change is one of the most
notable effects that are being felt today. The impact of climate change could have
far-reaching and unpredictable environment, social and economic consequences.
Indeed the climate change problem and the related changes it may bring about are
among the most serious of the environmental issues that we face today. For
example, these climatic changes encourage the movement of tropical diseases such
as malaria northwards, where populations have little or no immunity. The soil
fertility also changes and the agricultural productivity goes down as it shifts from
more fertile to less fertile regions.
Technologies are now available to recover methane trapped in coal seams by
drilling prior to and after coal mining. Recovery and use of this otherwise wasted
source of energy both reduces methane emissions to the atmosphere for the
protection of Global Environment and increases coal mine safety by eliminating
this flammable gas from work area.
