Optimum design and experimental analysis of air curtain system at the cabin door of refuge chamber
Abstract：To solve the closed performance problem of air curtain flow field at the cabin door of a coal mine refuge chamber,a two-dimensional chamber air curtain model was established with numerical simulation technology.The air curtain flow field with air curtain outlet width,air velocity and air flow angle was numerically simulated through changing amount parameters of the mathematical simulation model,and the air curtain system under limited air source was proposed.With experimental data and numerical simulated result analyzed and compared,the reasonable design technical parameters were obtained.At present,the air curtain system under limited air source of coal a mine refuge chamber was used successfully in several actual projects of KJYY-12/96 coal mine refuge chamber.
