Countermeasure Research And Distribution Law About Pneumoconiosis Of Coal Mine Peasant-worker In ChongQing

To provide scientific measures for the reduction of pneumoconiosis, we investigated the distribution status and occurrence regularity of pneumoconiosis disease in C hongqing C ity. In total of 20 coal mines pneumoconiosis present situation include towns, private and state-owned had been investigated in C hong Q ing, and the basic situation of mines, pneumoconiosis patient data and extract the migrant workers of coal mine were registered one by one and united coding, then imported into pneumoconiosis database. SPSS and excel software were used in statistical processing, frequency analysis and X² test.Data of investigation show that the average of migrant workers pneumoconiosis accumulative detection rate is 2.76±2.83. Pneumoconiosis patients began to dust exposure in the average age of 36.52 years, the youngest age is 16.92, the biggest age is 52.25.The average length of exposure to dust of the Patients is 11.1 years, at least 2 years, up to 31 years. The most number of the patients are between 5-15 years to exposure to dust. The average age of onset is 46.57 years. The youngest age is 34 years old and the biggest age is 59 years old. The influence of the prevalence of pneumoconiosis of different age began to exposure to dust, dust length of service and age of onset are significantly?p < 0.001?.About 85% of pneumoconiosis patients are mixed industry, main faceman and pure faceman. There are great effect on different work types of pneumoconiosis prevalence?X²= 53.871, p < 0.001?. The mean of free SiO₂ content is anthracite > bituminous coal > lignite. Under the assumption that the coal mine dust prevention measures, individual protective measures and so on are consistent, Morbidity from high to low is anthracite, bituminous coal and lignite, and the difference are significant?P < 0.001?. Migrant workers with an average age of 44, and less of them received high school or above education, more family population and less labor. Family per capita income is far less than C hina's migrant workers in 2014 per capita level. Family burden and rights protection is still tough after sick.The mechanisms and systems about pneumoconiosis' prevention and treatment are comprehensive. Measures of dust prevention are implementation in most coal mines, but a few also need to strengthen. Improved mine monitoring and evaluation of occupational hazard factors and shorten the examination cycle in posts. Prevalence of pneumoconiosis was associated with age began to pick up dust, length of exposure to dust, type of jobs, coal type and et al. M ix job, main coal job and pure of coal job should be the main prevention and treating population in miners. The relevant departments of unity and cooperation should take measures to prevent pneumoconiosis from the source.
