description The invention relates to the technical field of coal mine ventilation, in particular to a coal mine underground operation ventilation device and a ventilation method thereof.The coal mine underground operation ventilation device comprises a transfer cylinder, and a switching mechanism is movably arranged on the periphery of the transfer cylinder. The switching mechanism drives the refrigeration end of the semiconductor refrigeration sheet to extend into the transfer cylinder, so that the semiconductor refrigeration sheet is utilized to refrigerate and cool air in the transfer cylinder, air conveyed to the coal mine ventilation pipe is cooled, the coal mine is cooled, the situation that miners suffer from heatstroke due to the high temperature in the coal mine is avoided, and the safety of the miners is improved. And meanwhile, the state of a semiconductor chilling plate is adjusted through a switching mechanism, the heating end of the adjusted semiconductor chilling plate extends into the transfer cylinder, a
