目的为了解某矿务局井下接尘人员煤工尘肺发病情况,探讨尘肺发病特点和规律,制定有效防治方案提供依据。方法对该矿务局2 135名井下接尘人员进行高千伏胸部X线摄片检查,经市职业病诊断组集体阅片诊断,对诊断结果进行统计分析。结果井下接尘人员煤工尘肺发病率为1.08%,患病年龄多在45~55岁之间,工龄多在20~29 a之间。结论应加强井下接尘人员的健康监护及作业场所粉尘治理工作,以降低煤工尘肺发病率。
Objective To understand the incidence of coal miners’ pneumoconiosis in dust collectors in a mine bureau, explore the characteristics and rules of pneumoconiosis and provide basis for effective prevention and control measures. Methods A total of 2 135 underground miners in the mine bureau were examined by high kV chest radiography and diagnosed by collective occupational disease diagnosis group. The diagnostic results were statistically analyzed. Results The incidence of coal miners and pneumoconiosis was 1.08% in underground miners, the prevalence was 45-55 years old and the length of service was more than 20-29 years. Conclusion We should strengthen the health guardianship of underground dust collectors and dust control in workplaces so as to reduce the incidence of coal worker’s pneumoconiosis.
