Periodically, dust and gas impurities accumulate in the atmosphere of the quarry space, the concentration of which in some cases is so high that the production process in the quarry stops for a long time and the company suffers huge losses. Significant expenses are needed to normalize the purity of the atmosphere at the moments of its stable states.

The use of cyclones is one of the main directions in solving the problem of improving the atmosphere at the workplaces of drillers. Dust separation in these apparatuses occurs due to centrifugal force, which is received by dust particles when the air stream is fed at high speed tangentially into the cylindrical casing of the cyclone ...

The intensity of fracture product yield during rock drilling is in direct dependence on the drilling speed. The total yield of fracture products is taken into account when calculating dust removal systems and devices for accumulation of drill cuttings. However, it is known that the drilled fines have a complex fractional composition. The most dangerous for human health are particles smaller than 10 microns. These particles are able to stay in suspension for a long time and, accordingly, to spread to distant distances. Therefore, when evaluating the intensity of dust source from the point of view of its danger, it is necessary to be guided by the content of the smallest fractions in the drilling fines taken out of the well ...

Улучшение условий труда на открытых работах зависит от примене­ния надежных средств пылеулавливания для станков ударно-вращатель­ного и шарошечного бурения, работающих с продувкой скважины сжа­тым воздухом. Пылеобразование. при таком бурении настолько велико, что при неблагоприятных условиях буровые станки могут запылить карьер на больших площадях ...
