説明
A heading face is usually ventilated by forcing auxiliary ventilation system with duct and local fan, because heat, gases and dust particles by blasting or machines are liberated in the heading place rather than in other working places. A number of studies about ventilation at a heading face have been reported, but most of the results are based on assumptions due to difficulties in measurement of experiments and in theoretical analysis.<BR>However, as environmental problems arise from accelerated mechanization of heading operations, detailed investigations of air flow at a heading face is increasingly important for effective ventilation control.<BR>From this point of view, a theoretical study on the profile of ventilation air flow at a heading place has been performed. The 3D unsteady turbulance flow code which are solved by SIMPLER algorithm based on the finite different method was used in this study. It is shown in this paper that the results of simulation coincide with the actual phenomena and can be available to estimate of air flow of ventilation at the working places.
