The authors identified the sources of dust formation in quarries and risk of dust effect on staff health. This article presents dust properties depending on its fractional
composition and possible ways of use of dust in the production: the use as target products; return to the production that generates this type of dust; recycling in another production with obtaining of commercial products; recycling for construction purposes; agricultural use etc. The authors consider possibility of using pulverized coal as a new fuel. According to studies of granulometric composition of fragmented by explosion rocks of various hardness, for each kilogram of explosives during mass explosions gaseous cloud obtains from 80 to 320 g of particulate fraction of up to 20 microns. One can see a presented dust properties, depending on the particle size, and the dependence by definition of the dust and gas atmospheric pollution in the production of massive explosions. The authors also propose a new all-terrain vehicle with the air bag for collection and transportation of dust-raising bulk materials in the conditions of obstruction on the land, such as in quarries after blasting, excavation, works on movement of the rock mass, and others. This article contains the description and operating principle of the new vehicle, and the main parameters of speed airflow depending on the fractional composition of dust. Authors suggest dependences for differential pressure to create an airbag and the suction line, as well as in the flexible suction conduit, in the intake nozzle, in the filter and expenditure of transported air in the suction line.
Keywords: career; dangerous and harmful manufacturing processes; raw materials dust; dust removal; vehicle; labor safety; airbag; compressed air; differential
pressure; vacuum.
