摘　　要：为了探究南屯煤矿33_(下)06运顺掘进巷道的热环境分布情况、完善通风措施,对该巷道进行了热环境分布探究现场实验与数值模拟。研究结果表明:现阶段的通风参数可满足安全生产需要;在进行通风降温时,越靠近掘进面与风筒出口区域,降温效果越好;在通风一段时间后,巷道内温度呈现出四周高、中间低的分布特征;在同一横断面内,温度呈现下侧低、上侧高的分布特征。In order to investigate the distribution situation of thermal environment in the 33_(down)06 transportation channel excavation roadway of Nantun Coal Mine and improve ventilation measures,on-site experiments and numerical simulations are conducted to investigate the distribution of thermal environment in the roadway.The research results indicate that the current stage ventilation parameters can meet the needs of safety production;When conducting ventilation and cooling,the closer the excavation face and the outlet area of the air duct,the better the cooling effect;After a period of ventilation,the temperature inside the roadway exhibits a distribution characteristic of high around and low in the center;Within the same cross section,the temperature exhibits a distribution characteristic of low on the lower side and high on the upper side.
