| 摘 要： | 煤层自燃是一个动态变化的过程,随着自燃向不同方向扩大或缩小,其热场随着燃烧过程而发生空间变化。本文在研究煤田煤层自燃现象及其火区灾害特征的基础上,基于宁夏汝箕沟地区的四层空间遥感探测试验,总结了不同平台遥感方法的探测效果,提出了利用遥感方法实现地下煤田火区监测的有效方法。 |
| 关 键 词： | 煤层自燃 地下火区 四层空间 遥感探测 热导成像 |

| Abstract: | Coal fire is a dynamic process caused by spontaneous combustion of the coal layer in various directions, accompanied by the sensible thermal field variation both in time and in space. Using appropriate assemblies and sensors in different layers for effective identification, this paper has studied the technology for detection of underground coal fire. The test was carried out in Rujigou coal fire area of northern Ningxia on the basis of investigating coal fires and related physical features sensible to thermal detection. On such a basis, the effective and economical methods are proposed for the monitoring of underground coal fire. |
| Keywords: | Spontaneous combustion of coal layer Underground coal fire Four-layer layout Remote sensing detection Thermal source imaging |
