An assessment of mine methane mitigation and utilisation technologies

The existing and developing technologies for coal mine methane mitigation and utilisation are classified, with a discussion of the features of different technologies to identify potential technical issues for each technology when implemented at a mine site and to identify the best options for mine site applications. A technical assessment of these technologies for use at a Queensland coal mine is presented, with a preliminary economic assessment of some technologies that were determined to be technically feasible. The assessment is carried out on the basis of real mine methane emission data over about a 1-year time frame.
