在煤矿的生产作业过程中，如机采、综采、炮采、回采、锚喷、装运、选煤等工序，均可产生大量的粉尘，工人长期在高煤尘浓度的环境中作业，吸入呼吸性煤尘可引起尘肺，严重危害着煤矿工人的身体健康。因而，必须采取有效措施加以控制。 一、国外煤尘控制技术介绍 在国外，煤矿 In the process of coal mine production, such as mining, fully mechanized mining, blast mining, mining, anchor spraying, shipping, coal preparation and other processes, can produce a large amount of dust, workers in the long-term high dust concentration environment work, inhalation Respiratory dust can cause pneumoconiosis, seriously endangering the health of coal miners. Therefore, we must take effective measures to control. First, foreign coal dust control technology introduced in foreign countries, coal mines
