The distributions of air temperature is similar to that of moisture content in the locally ventilated working face, and the variations in sensible heat and latent heat from the surface of the roadway into the working face with time and wetness factors were analyzed, with the increase of wetness factor, latent heat flux increases, sensible heat flux decreases, and the total heat flux increases. The 3-dimensional k-ε turbulent flow model was used to simulate heat-and mass-transfer in a heading face with forcing auxiliary ventilation system. Based on the results of the research, assessment of the impact of heat emission from coal on the air temperature within longwall faces developing steep seams is given. There is also a new approach for recognition of heat transferring surfaces from a coal seam and developed space as for faces using pneumatic hammer and combining technologies of coal extraction. Besides, there are engineering methods for calculation of heat emission from coal within faces under border condition of first and third types. ![]() There is a mathematical model for convective heat exchange between air and fossil in faces that develop steep coal seams, which includes a number of simplifying assumptions as well. At the same time, in face with steep occurrence of seams, where delivering of material is affected by gravity force, one should consider convective heat exchange of coal fraction within the air stream. In faces with flat and sloping occurrence of seams the coal on conveying unit is considered a half-closed body, the surface of which provides convective heat exchange with air. In the present work we have determined difference of heat-exchange processes between fossils and air within faces during development of steep flat and sloping coal seams. The biggest error in prediction of temperature conditions is revealed in calculations of air temperature in faces developing steep coal seams, which is related to the peculiarities of technological processes taking place in excavation of coal. The paper shows the need for increasing accuracy of heat calculations in choosing chilling equipment for normalization of temperature conditions in working faces.
