摘要：

In general, tunneling workings are located in deep underground isolated from the main ventilation networks. Workers in tunneling faces are exposed to the air contaminated mainly by the contaminants from diesel exhaust or after-gas of explosives. To tackle with this matter, it is essential to figure out the exact phenomenon of gas movement in the concerned spaces. This paper presents the trend of gas movement in the dead-end workings using diesel equipments to provide informations for designing adequate ventilation system. For analyzing of gas movement, a newly developed software(3D-Flow) for 3-dimensional flow movement was used which is based on computerized fluid dynamics.
