Dynamic impact experiment system and method of corrosion coal containing gas

The invention discloses a dynamic impact experiment system and method of corrosion coal containing gas. The system comprises an impact member system, an exhausting system, a gas feeding system and a corrosion working system, wherein the impact member system comprises an incidence rod, a transmission rod, a flexible patch, a coal sample, a steel cavity, a sealing washer, a fastening bolt, a nut, a YX-type sealing ring, a pressure sensor, a pressure gauge, a data acquisition instrument, tempered glass, an O-shaped sealing washer and a bolt; the exhausting system comprises an exhausting valve and a vacuum pump; the gas feeding system comprises a gas feeding valve, a solenoid valve, a decompression valve and a high-pressure gas bottle; and the corrosion working system comprises a solution box, a corrosion solution, a heater, a first brake valve, a first liquid pump, a first flow meter, a second brake valve, a third brake valve, a second liquid pump, a second flow meter and a fourth brake valve. According to the invention, response properties of the coal which is deeply influenced by environment temperatures and is corroded by underwater or a hydraulic measurement working solution can be researched after the coal is subjected to impact power, and the dynamic impact experiment system and method have theory and engineering practice meanings.
