Development and State of the Art of Dust Control in International Mining and Tunnelling

The quest for safety for man and machine is becoming increasingly important in mining and tunnelling worldwide. Due to the mechanisation of sinking, tunnelling and extraction work in underground mining and processing, the amount of dust generated in the various work processes has steadily increased – in line with the increase in performance. Although the occupational disease silicosis, which is ...

Dust Control in a Novel Technology for the Construction of Shafts

In Belarus, potash mining has been carried out intensively for about 60 years, so far by the state-owned company Belaruskali in six mines. Since 2011, the privately financed Nezhinskiy mine has been planned in the deposit near Soligorsk, and construction of this greenfield mine started in 2016. The planning from 2011 initially envisaged the sinking of two shafts using the ...

Heat and Moisture Related Ventilation Problems for Dust Extraction Efficiency during Underground Roadheading Operations

Ventilation measurements and data from several days of underground monitoring were used to record the actual status of the mine climate and ventilation circuit at a rock salt mine. This provided the basis for identifying a number of critical parameters, including the problem of dust collection around boom-type heading machines. This information was then used to determine where potential improvements ...

Technical Aspects of Auxiliary Ventilation at Dust-Intensive Workplaces

Many different technical relationships and parameters have to be taken into account for the professional cleaning of dust-laden air. Filtering the dust load from the air requires a fan system to set the air in motion so that it can pass through the filters. In mechanised drivages and conventional tunnelling operations the technical ventilation methods being deployed have to be ...

Continuous Respirable Dust Monitoring with Localization

The U.S. Mine Safety and Health Administration (MSHA) mandates the use of continuous personal dust monitors (PDM) in underground mines to verify compliance with mandatory respirable dust standards. Regulation 30 CFR §70.100 establishes a limit of 1.5 mg/m3 averaged over an eight hour working shift. Miners who work in dusty conditions are required to wear the PDM for several shifts ...
