Description:
A new measurements methodology has been developed which allows the rapid and efficient measurement of methane (CH4) emissions from surface coal mines. An initial field trial of this methodology has been completed, and results from the field trial revealed that emissions from one surface coal mine in the U.S. are estimated to be 1,735,000 m3/year. The results provide some evidence that CH4 concentrations determined by the FTIR may be low by 20 to 75 percent but the overall effect of this potential bias on the mine emissions estimate cannot be adequately quantified. The initial trial demonstrated that the methodology is an applicable and feasible approach for measuring CH4 emissions from very large surface coal mines. It also highlighted several uncertainties and methodology questions which if resolved could further improve the performance and reliability of the methodology.
