Experimental Study of the Tunnel Thermal Environment Adjustment
2012
Abstract. The purpose of the paper is study the tunnel air environment adjustment. We built a set-up according to the similarity law. Temperature, air flow velocity, and the humidity in the model tunnel were measured using a measurement system. Experimental data were obtained under the ventilation duct at the top of the tunnel. The results show that adjusting velocity and humidity of the supply air flow can satisfy the Safety Regulation for Metal and No-metal Mines.
