Coal mining generates dust via coal cutting transport crushing and milling Exposure to coal dust is preventable through administrative controls and engineering controls Recognised Standard 2020 is a legislation based administrative control for the safety and health of coal mine workers.Laboratory crushing experiments were conducted in a wind tunnel with a roll crusher to identify relationships among crushing parameters product size coal rank properties and airborne dust.
The coal processed varies from dry dusty coal to wet cohesive coal that can often block sections of the transfer chute The air generation can often be significant in the stilling chamber on the out going conveyor due to the large drop height making it a formidable task to design a reliable dust.The coal dust problem are being pursued continually Coal dust explosions are still occurring however and many unsolved problems on this subject still remain ' This is due in part to thelr complexity and to the many parameters that affect the ignition sensitivity and the explosibility of coal dust.
Using Dry Fog at Coal Crushers to replace dust collection and chemical spray systems has yielded excellent results In addition to increased dust control plants report that the costs of O M can be up to 4 times lower than collection.Control systems permit the plant's generating units to convert 24 000 tons of coal into 56 million kilowatt hours of electricity daily in a clean and acceptable way In 1981 Pennsylvania Power Company installed a dust collection system on its primary crushing system to collect dust fines generated at the crushers and conveyor transfer points.
