Estimating methane emissions from coal mines

FormulaGas ContentEmissions Factor CoefficientIPCC MethodologiesGlobal Coal Mine TrackerAbandoned Mine MethaneThe CH4emissions for a coal mine can be calculated with the following formula: Annual CH4(in million cubic meters) = Production * Gas content at mining depth * Emission factor coefficient Example for a deep, underground bituminous coal mine, with a depth of 465m: 1. Production: 5 million tonnes per annum 2. Gas content at mining depth: 13.4 m3/tonn...
