Abstract
Fire is one of the major hazards in coal mines. After the fire broke out.the primary task of disaster rescue is to judge the location of fire and it is the prerequisite of analyzing the combustion state, the base of fire prediction. In this paper, the method of tunnel fire location judgment combining with qualitative and quantitative analysis is used, it includes the qualitative analysis basing on sets theory and quantitative analysis on fuzzy clustering. The potential location can be conversely reasoned by the warning sensors and the scope can be narrowed down widely. On this basis, the distance and similarity between the veritable time difference and the numerical simulation difference are calculated and by the value we can know the site of the fire.
