Abstract

China has the largest coal resources in theworld but these are seriously endangered by coal fires. Though the problem of coal R res is long standing and not only limited to China, little has been done for regular monitoring of these fires. This Letter proposes the use of multi-temporal night-time thermal images acquired from Landsat Thematic Mapper band 6 for establishing a coal fire monitoring system for a coalfield in north-west China. Other images and map data are fused with the thermal images to provide a comprehensive picture of the fires through the years. Finally the fires are classified into di€ erent categories based on multi-temporal changes.
