长壁工作面粉尘的危害长期以来一直是采煤工业期待解决的一个大问题。据美国矿山安全和健康管理局(MSHA)的调查证明,长壁工作面的滚筒式采煤机司机受呼吸粉尘的危害程度通常比工作面其它设备的操作人员严重。据MSHA的有关人员说,被调查的许多滚筒式采煤机司机的工作地点空气中的粉尘含量都超过了联帮管理局规定的2mg/m~3的标准。尤其是使用双滚筒式采煤机的工作面。 针对这个问题、矿业局匹兹堡研究中心与美用伊利诺斯州的韦斯特蒙特国际有限公
The hazards of dust on longwall faces have long been a big issue that the coal mining industry is looking to address. According to a survey by the United States Mine Safety and Health Administration (MSHA), drum shearer drivers with longwall faces are generally more damaging to breathing dust than operators of other equipment on the work surface. According to MSHA officials, the dust levels in the air of many drum shearer drivers surveyed exceeded the 2 mg / m 3 standard set by the Association. Especially the use of double drum shearer face. In response to this problem, the Pittsburgh Mining Research Center and the United States Westmont International Limited Illinois
