Abstract

Systems for dust extraction in roadway workings subjected to suction or forced ventilation are a combination of dust collecting equipment and facilities designed for ventilating the working. Such a combination of suitable equipment provides safe and effective dust removal and ventilation of a roadway working as well as is determinant of proper cooperation of the equipment a system is composed of. The development of effective dust collectors of wet type which provide safe operation under conditions of great exposure to coal dust and methane explosion hazards as well as of vortex ventubes allowing methane accumulations under the roof to be removed makes it possible to apply regularly the designed systems. The efficiency of dust collecting equipment ranges from 99o/o to 99.8%. Measurements of the efficiency are carried out on a measuring stand in conformity with polish standards and when applying the dust of grain size as established by the standards.
