| 摘 要： | 煤田火灾问题存在由来已久且不仅仅局限于中国，如何利用遥感技术进行煤田火灾监测正引起广泛关注．早期的研究主要是利用白天的Landsat TM6波段的热红外信息进行煤火的监测．本利用多时相的白天和夜晚热红外遥感数据，对煤田火灾进行动态监测．以宁夏汝箕沟煤田为研究区，对煤田的火灾范围及其动态变化过程进行了分析．据此对地下煤火的变化类型进行判断，确定煤火是新产生的还是相对稳定的。从而为煤田灭火提供必要的决策支持。

| Abstract: | The problem of coal fires has existed for a long time and is not only limited in China. Therefore, great concern has been caused by the regular monitoring of these fires based on remotely sensed data. Some researchers have used day-time thermal images from Landsat TM band 6 to monitor coal fires. In this paper, Rujigou coalfield in Nixia has been selected as study area. Multi-temporal day-time and night-time thermal images of coal fields were used to provide an overview of the changes in spatial location and scope of fires with time. Judge accordingly for the change type of underground coal fire, determine coal fire was a newly produced or a relatively stable one, and also can make decision support for coalfield fire extinguish. |
