苏联和欧美各国普遍把除尘器除尘作为掘进工作面和其它局部产尘点的降尘措施,使掘进工作面的粉尘浓度大大降低。据介绍,1975年,英国1430个煤巷掘进工作面中,粉尘浓度达到10mg/m~3的有1414个,在1044个岩巷工作面中,有411个达到2 mg/m~3的标准。最近,国外一方面在采煤机上试验除尘器除尘,另一方面,还继续开展研制其它机理的除尘器,以进一步扩大其使用范围和提高使用效果,使其更小型化、简单化。据各国实践经验和研究表明,
The Soviet Union and Europe and the United States generally put the dust collector dust removal as a driving face and other local dust production dust control measures to reduce the concentration of dust on the heading face greatly reduced. According to reports, in 1975, the United Kingdom 1430 coal heading face, the dust concentration reached 10mg / m ~ 3 of 1414, 1044 rock face work face, 411 reached 2 mg / m ~ 3 standard . Recently, on the one hand, foreign countries have been experimenting with dedusting dust collector on shearer. On the other hand, they have also continued to develop dust remover for other mechanisms to further expand their range of use and enhance the effect of use, making them more compact and simpler. According to various countries’ practical experience and research,
