In this paper, we report the dynamic observation and analysis of 351 silicosis patients in 351 operations of veterans who work in tunnels. The prevalence rate is 18.23%. The occurrence and development of late silicosis is similar to that of common silicosis, which is closely related to the type of work and length of service. This article suggests that the length of service in the incidence of 2.5 to 10.0 years, late onset of a long time, the combined prevalence of tuberculosis is low, a small percentage of promotion, a long promotion, and the clinical manifestations of the respiratory system, the typical x-ray tunnel operations for the military Late silicosis characteristics.
