Abstract：With the development of coal mine modernization,information and intelligence,explosion-proof trackless rubber-tyred vehicles are more and more widely used in coal mine.The tail gas pollution caused by explosion-proof trackless rubber-tyred vehicles is serious during its operation,especially,carbon monoxide(CO),nitrogen oxide(NOx)and fine particulate matter(PM-RRB-in the tail gas seri-ously pollute the underground air and endanger the health of underground workers.Aiming at the present situation of the tail gas pro-duced in the operation of the explosion-proof trackless rubber-tyred vehicles in Shaanxi Guojiahe Coal Industry Co.,Ltd.,using en-hanced oxidation type catalyst(DOC-Z)technology and catalytic type particle trap(CDPF)technology to treat tail gas can effectively improve underground air quality by purifying harmful substances such as CO and PM in vehicle tail gas.
