Zusammenfassung:	The utility model relates to a mine gas monitoring pre-pumping and sampling device, which comprises a device body. A bus-bar is arranged on the left side of the device body and is connected to a solenoid valve through a pipeline; the solenoid valve is connected to a sampling pump; and a flow sensor is arranged on the pipeline which is connected to the solenoid valve and the sampling pump. The utility model has the advantages that the mine gas monitoring device can sample the gas and perform the infrared analysis on the on-site sampled mine gas so as to realize the real-time monitoring for the mine gas and the real-time monitoring for the mine firing tube of flux and automatically control. The device is convenient to assemble and use, the pumping efficiency is high, the reliability is high, the service life is long and the device is free from maintenance.
