Analysis the Concentrations of Toxic and Harmful Gases in Ventilation of Underground Caverns

Abstract:

For ventilation of underground cavern construction, analysis and research the state of motion of the gas in the ideal state and ventilation processes derived the formula of the concentration changes during the construction ventilation toxic and harmful gas diffusion reveals the variation of the diffusion of toxic gases, and engineering examples to verify the theoretical analysis. At the same time, simulation analysis the concentration changing curve of toxic and harmful gas, obtained the ventilation of cavern under different ventilation. The results show that ventilation mode of a constant amount has some shortages in energy efficiency.
