In order to explore the distribution pattern of smoke in mine roadway fire disasters caused by internal and external factors in inclined roadways,and to address the serious threat of high-temperature toxic smoke to underground personnel's disaster avoidance and rescue work during mine fires,the Fluent numerical simulation was used to construct a 1:1 inclined roadway model.By adding a fine water mist system,the smoke movement and temperature changes in inclined roadways under 7 slopes and 2 fire source powers were studied.The results showed that under the condition of inclined roadway without fine water mist,the downstream roof temperature contin-uously increases with the increase of roadway slope,and the highest temperature reaches 265 ℃ when the roadway slope is 20°.The in-clined roadway condition with the addition of fine water mist results in a continuous decrease in downstream roof temperature with the increase of roadway slope.As the slope increases,the cooling effect of fine water mist becomes more pronounced.
