Based on the mechanical maintenance of Heavy Haul Railway Survey and field occupation hazards detection,we have basically grasped the type of occupation hazards in large maintenance machinery maintenance work and contact level. Track mechanized maintenance of occupation hazards to contact in the process of operation are: noise,dust,carbon monoxide,carbon dioxide,nitrogen oxides,sulfur dioxide. The monitoring results showed that dust exposure limit maximum ratio of 12. 7,the qualified rate of dust exposure was 81. 0%( Total Dust) and 98. 3%( Respirable Dust),the total dust qualified rate of cleaning operator of rail surface( 40%) and field commander( 33. 3%) is the lowest; noise field monitoring values up to 100. 5 dB( A),the qualified rate of noise was 48. 6%,among which the monitoring personnel of the tamping rail surface the lowest qualified rate was only 9. 1%; the qualified rate of exposure to chemical factors was87. 3%. The research presented China Shenhua track mechanized maintenance branch of enterprise standards,specification and suggestions,provided scientific,normative and specific practical scientific evidence for enterprises to control workplace occupation hazards and prevention of occupation disease.
