THERMAL REMOTE SENSING METHOD IN DETECT AND MONITORING SUBSURFACE COAL FIRE IN KHANH HOA COAL MINE, THAI NGUYEN PROVINCE
AbstractThe Khanh Hoa coal mine is a surface coal mine in the Thai Nguyen province, which is one of the largest deposits of coal in the Vietnam. In recent years due to many reasons such as backward mining techniques and unauthorized mining caused subsurface coal fire in this area. Coal fire is a dangerous phenomenon which affects the environment seriously by releasing toxic fumes which causes forest fires, and subsidence of infrastructure surface. This article presents study on the application of LANDSAT multi – temporal thermal infrared images, which help to detect coal fire. The results obtained in this study can be used to monitor fire zones so as to give warnings and solutions to prevent coal fire.
