ABSTRACT

Methods for gas extraction are currently ranked among clean coal technology. Coal gas
is a normal part of coal deposits and its mining reduces methane emissions.
Underground coal gasification is a non-traditional mining method that also allows use of
coal deposits which are not possible to be mined by traditional methods. These
technologies bring both positive and negative aspects affecting the environment. This
contribution is covering the influence of gas extraction from coal deposits on the environment accompanied by particular examples of some of deposits around the world.

Keywords: coal gas, positive and negative aspects of the environment
