Zusammenfassung:	The utility model relates to a mining multi-hole pore plate flow guide pipe which comprises an air inlet pipe and an air outlet pipe which are connected into a whole, an integrated multi-hole pore plate is fixed at the connecting position of the air inlet pipe and the air outlet pipe, and a plurality of air outlet holes are formed in the multi-hole pore plate. A concentration air inlet sampling nozzle, a concentration air outlet sampling nozzle, a differential pressure dynamic pressure sampling nozzle and a differential pressure static pressure sampling nozzle are fixed at the transition position of the air inlet pipe and the air outlet pipe, the differential pressure dynamic pressure sampling nozzle is fixed at the air inlet pipe section, the differential pressure static pressure sampling nozzle is fixed at the air outlet pipe section, and a sealing protection cover is fixed on the outer side of the transition position of the air inlet pipe and the air outlet pipe. And sealing plugs matched with the sampling
