The level of dust pollution appearing during the dump of cars loaded with crushed limestone is defined. The data on the composition of the dust particles dispersed into the air in the working area during the cars loaded with rubble dump is obtained. The scheme of experimental-industrial dedusting ventilation and the results of its tests are described.
