title: [Analyses of 1003 death cases of pneumoconiosis from Xuzhou coal mines].
abstract: In order to investigate the general rules concerning attack, development and death of pneumoconiosis for providing scientific evidences for preventing, 1003 death cases of pneumoconiosis from Xuzhou coal mine factory were analyzed. Results showed that: (1) The death causes was in the sequence of pneumoconiosis, lung tuberculosis, chronic cor pulmonale, pulmonary carcinoma, etc., and changed into pneumoconiosis, chronic cor pulmonale, pulmonary carcinoma, cerebrovascular accident, etc. since 1990s. Lung tuberculosis would no longer be the main death cause of pneumoconiosis; (2) The accumulative death percentage of the death cases about pneumoconiosis was correlated to the length of dust exposure. The accumulative death percentage increased rapidly in a beeline within 5 to 20 years; (3) The length of service of episode and mean life of digging or mining workers were significantly shorter than that of others (P < 0.01); (4) The mean life and the course of diseases became more and more longer than ever since 1970s. Therefore, it can be concluded that the key for preventing and controlling pneumoconiosis was to decrease the concentration of dust in workplace and to limit the length of service of dust exposure.
