Study on infrared detecting technology of the spontaneous fire position at the coal road on mines

摘要

To reduce and remove the coal spontaneous fire accident at coal road, it is of importance to study the detecting technology of the spontaneous fire position. In this paper, the main detecting means, such as magnetic, resistivity, niton, index gas, infrared (IR) and temperature detection means, and so on, are given. i nthese means, the IR detecting means has apparent advantages compared with the other means, its detecting properties and theory have been put forward, and the application example is presented.
