Abstract:
In this research,taking Jurassic Datong coal mining area as an experiment area,Landsat TM images on July 5,2010 as a data source,and the mono-window algorithm was chosen to retrieve Land Surface Temperature (LST).Combined with the known coal fire location information to extract the coal spontaneous combustion hazard zone in the study area.By correcting the extraction field verification results of research results and the problems were discussed.Result of the extraction was revised by field check and also discussed the problems about the research achievements in this paper.At the same time,given a combined three-dimensional display of coal spontaneous combustion zone and remote sensing image.The results showed that the number of coal spontaneous combustion hazard zone in the study area was 12 in 2010,and the fire area totaled 7.61km
2,accounting for 1.2% of the total area.Simultaneously,the accuracy for information extraction was 83.33%.To a certain degree,it provided a technical reference for the extracting coal spontaneous combustion by remote sensing.
