Early detection of mine fire in underground by using smell detectors
- Hokkaido Univ., Sapporo (Japan)
In our laboratory, a new detection system using smell detectors was developed to detect the spontaneous combustion of coal and the combustion of other materials used underground. Laboratory experiments were carried out on several kinds of coals, including South African coals, and machine oil, wood and rubber used in belt conveyers. The following results were obtained: (1) Spontaneous combustion of coal can be detected earlier by smell detectors than by conventional CO detection methods. (2) There were no differences in the results using different kinds of coal. (3) Combustion d other materials can also be detected earlier by this system than by conventional detectors for gas and smoke. (4) Use of this detection system enables one to discern the source of the combustion gases, whether it be coal, wood, oil or rubber.
