随着煤炭工业机械化水平不断提高,机械化掘进巷道的除尘问题已显得越来越重要和突出起来。在机械化掘进工作面中,粉尘浓度高达2000～3000毫克/米~3。粉尘对矿井安全生产和矿工身心健康的危害已日益严重。研究适于我国煤矿生产技术条件的除尘设备和综合除尘措施,在当前有着重大紧迫的意义。 With the continuous improvement of the mechanization of the coal industry, the problem of mechanized roadway dust removal has become more and more important and prominent. In mechanized heading face, dust concentration as high as 2000 ~ 3000 mg / m ~ 3. Dust on the mine safety and health hazards and miner health has become increasingly serious. It is of major and urgent significance to study dust removal equipment and comprehensive dust removal measures suitable for the technical conditions of coal mine production in China.
