一前言 煤矿采掘、运输等生产过程中,不可避免地要产生粉尘。它们既污染作业环境,又危害煤矿工人的身体健康。特别是有爆炸危险的煤尘,会给煤矿的安全生产带来极大的危害。 工业粉尘对人体的最大危害是粉尘进入肺部后能引起各种尘肺,其中以矽肺最为普遍,危害也最大。矽肺的发生和发展与吸入肺部粉尘的性质、浓度和粒度等都有密切的关系。粉尘中游离二氧化矽的含量越高,矽肺的发病率也越高。粉尘的粒度不同,进入 A preface Coal mining, transportation and other production processes, inevitably have to produce dust. They not only pollute the working environment, but also endanger the health of coal miners. In particular, the explosion of coal dust, coal mine safety will bring great harm. Industrial dust on the human body's greatest danger is that dust can cause a variety of pneumoconiosis after entering the lungs, of which the most common silicosis, the most harmful. The occurrence and development of silicosis and inhalation of lung dust nature, concentration and size are closely related. The higher the content of free silica in the dust, the higher the incidence of silicosis. Dust particle size is different, enter
