The Flow Study During The Fire In Mining Laneway

Basing on the fundamental theories of the combustion, the hydrodynamics and the heat-transfer, the author of the paper establish the mathematics model, which could describe the fume flow during the mine fire. By the means of theory analysis, numerical calculation and model experiment , the variational character of different parameters of high-temperature fume flow such as the temperature, the consistency and so on is discussed when the fire happen out in the mining tunnel. Under certain hypothesises and simplifications, the original and boundary condition may be confirmed according to the variational character and practical state in high-temperature fume flow. On the basis of this, the 2-Dimention field model and the 1-Dimention field model for fume movement is solved by using the SIMPLE numerical calculation, and the computer code for which was compiled. Then, the simulative result is compared with the experimental result. It is proved that the field model, the computer program and the simulative result are all correct in the thesis. At the same time, the variational characters of the temperature and consistency of the fume which flows along the mining laneway in different conditions are analyzed.
