Coal-bed methane (CBM) is composed primarily of gas and it is a clean and efficient energy of high value. Based on the theory of gas geology, usually there will be an anomaly of land surface temperature at the area where the density of CBM under the coalmine is high. Land surface temperature at coal mine district is retrieved by using ASTER band 13 (10.7 mum) and band 14 (11.3 mum) combined with split-window algorithm. The atmosphere transmittance is simulated through MODTRAN 4 and land surface emissivity is calculated from NDVI. The temperature anomaly areas in the result image are suspect high CBM density areas and the causes of the temperature anomaly are discussed at the end.
