| Abstract: | A logic fault tree of mine spontaneous combustion of sulphide ores was built by the fault tree analysis (FTA) based on a lot of mechanism investigation of sulphide ore spontaneous combustion in more than ten mines and review of a great amount of relevant literature. The fault tree is composed of 17 key contributory factors. After making a qualitative analysis of the fault tree, the minimum relevant factors for assessment of inherent self-heating potential and the optimal pathes for controlling fire were put forward. A mathematical model based on the heat transfer and diffusion theory is recommended to pre-estimate quantitatively the fire risk in field. |
