全死因调查是研究人群健康状况的重要方法,用它来探讨煤矿工人的死亡水平、死因构成及其变化规律;可以从死亡的角度反映煤矿工人的健康水平,和各种职业危害因素及有关疾病死亡对煤矿工人生命威胁的严重程度和发展趋势。对象和方法基本情况:漳平煤矿建于1958年,岩尘游离二氧化硅含量20.55～83.34%((?)=47.70%);煤尘游离二氧化硅在1.16～9.15%((?)=4.79%)。建矿和生产初期,使用干钻凿岩,粉尘浓度曾超标数百
All-cause investigation is an important method to study population health status. It can be used to explore the level of death of coal miners, the cause of death and its variation. It can reflect the health status of coal miners and various occupational hazards and related diseases from the perspective of death The severity and trend of death threats to the lives of coal miners. Objects and Methods The basic situation: Zhangping Coal Mine was built in 1958, with dust free silica content of 20.55-83.34% (? = 47.70%); coal dust free silica at 1.16-9.15% (?) = 4.79%). In the early stage of construction and production, the use of dry drilling rock drilling, dust concentration exceeded hundreds
