Data from TM images from the years1986,1993, 2000 and 2006 around Shenfu coalmine area were used to exbract normalized difference vegetatio n index by the software ERDAS firstly, then using spatial modeler of ERDAS compute vegetation fr action and classify through unsuperˉ vised classification.Finally,we get vegetation fraction mapping of c oalmine within 1986～2006.It clearly inˉ dicate that the coalmine vegetation fraction increase in whole but d ecrease in some colemine district.
