Mine Rescue for the Future Underground
Smart mining allows the industry to meet current and future challenges. The corresponding solutions include digital networking, automation and robotics. Mine rescue also benefits from this development – as well as from the further developments in functionality and ergonomics of established solutions such as closed-circuit breathing apparatus. Author/Autor: Peter Thomas,…

Innovation on Suspended Monorail Locomotives for Underground Coal Mine Applications – a Project Overview
Suspended monorail locomotives are an important mining equipment for the transport of personnel and material in underground coal mines in Europe. A wide variety of diesel-driven or battery-electric locomotives are available. The EU-funded research projects BUSDUCT and HEET II conceptualized two alternative methods of electric power supply for suspended monorail…

Emerging Global Trends in the Extractive Industry – International Potential and Future Roles of Remediation Expertise from Germany
Never in history were more mineral resources extracted than at present. In the past 20 years alone global metal ore extraction doubled. If current growth rates continue, more metals will be mined by 2028 than from the beginning of humankind to 2013. This exploding demand is set to rise even…

Suspend Coal Phase-Out – Keep Existing Plants in Operation and Reactivate Available Capacities, Give Transition More Time
While there are no fundamental doubts about the direction of the energy transition in Germany – much less the goal of achieving sustainability – the changes in the general circumstances dictating energy policy that have occurred in 2022 give rise to sound arguments in favour of suspending the coal phase-out…

Securing an Air Shaft in Witten, Taking into Account an Overburdened Mine Water Level
At the beginning of March 2020, the Arnsberg District Government, Department of Mining and Energy in NRW, Dortmund/Germany, was notified of a repeated significant inflow of water in the area of a residential building in Witten. In view of the damage that had already occurred to the building and according…

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…

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…

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.…

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…

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…
