Systematic Quantification Of Ventilation Air Methane And Its Evaluation As An Energy Source

Production of methane is an inevitable consequence of mining coal. Although the number of mines practicing recovery of methane prior to, or during, coal mining is increasing, ventilation air methane (VAM) is still a significant source of methane addition in to atmosphere. Recent studies have shown that there are ways to recover the VAM energy, while simultaneously reducing the methane emission in to atmosphere. This paper discusses a case study, currently underway, to develop a technique to quantify the VAM emission from a mine. It also presents the different VAM utilization techniques and the suitability of one for the mine being studied. Finally, the paper summarizes the research issues that require further investigation.
