Dust suppression systems for receiving bin of in-pit crushing and conveying plant at the Muruntau Mine

The article describes the method of dust suppression during unloading of dump trucks at in-pit crushing and conveying point No. 10 at the Muruntau Mine based on design developments. The bin, feeder and crushers are the main components of the IPCC point. Amount of dust generated in the bin of the IPCC point during unloading of rocks from dump trucks, dust size and velocity directly depend on the environmental conditions. Dust generated during unloading of rocks from dump trucks harms the environment. In this respect, for the dust suppression, along the bin and feeder, a closed system was designed, where pipes with water jets were installed. The jets required for the dust suppression were selected based on calculation, and the sizes of dust particles, their velocity and diameter were determined experimentally and from calculations. The developed method of dust suppression shows the dependence of dust suppression with water on concentration of dust, pressure of water, diameter of jets and size of dust particles in the bin and feeder. The economic efficiency of the closed water spraying method to suppress dust generated during unloading of dump trucks is calculated.
