— Use traffic control as a dust control technique Max exposure occurs within 4 15 seconds behind a haul truck Require trucks to maintain more than 20 seconds of separation May result in a 40% 50% reduction in respirable dust exposure to the following truck
WhatsApp
— Surfactant enhanced water spray technology one of the most economical and efficient dust suppression technologies is widely used for dust control in mining Unfortunately current research on this technology appears to be scattered and the results do not provide an effective approach for coal dust control
WhatsApp
— Among the existing dust control methods ventilation spray and dust suppressants were considered the most practical and common technical methods for dust control in metal mines [29] It is necessary to choose a single or multiple combination of dust removal methods based on the characteristics of different dust sources
WhatsApp
— A variety of dust control methods are often applied in coal mines among which the application of wet scrubbers has proven to be an efficient technology for the removal of dust in airstreams rather than diluting or confining the dust In this paper a wet scrubber design was developed Based on a self designed experimental test platform the
WhatsApp
— Water is the go to method for dust control It s cost effective and gets the job done Spray trucks can gently mist water on areas with dry loose dirt preventing dust from being kicked up and going airborne Just avoid using sprinkling systems that could create mud or flooding on public streets as this poses a safety hazard for drivers
WhatsApp
— The term dry fog is used for its resemblance with natural fog and does not make the material wet The dry fog is generated using the energy in the compressed air to shear the water particles of 1 50 μm size with a mean of 20 μm diameter Fig 1 The fog creates an impenetrable blanket over the dust source and the velocity of the compressed
— Since it is very difficult to control dust once it becomes airborne all measures should be aimed at suppressing it at the source A properly de signed water spray system can reduce respirable dust by 20 to 60 percent To effectively control dust a shearer must be equipped with two types of water spray sys tems internal drum sprays which
