MINEXPO PREVIEW
reduces fuel consumption compared with competitor ’ s fans on the market , and Horton ’ s decades-long tradition of producing reliable , durable products ensures longevity of the entire cooling system , it said .
Both models – the RCV2000 and the RCV1000 – will be shown on the company ’ s booth .
Celebrating its 10th anniversary with new solutions to deliver worker safety and productivity improvements underground , while reducing energy and greenhouse gas ( GHG ) emissions , Maestro Digital Mine will have a range of products on show at its MINExpo booth .
The company manufactures IIoT devices and last mile digital networks for underground mines tackling many of the industry ’ s ventilation , communications and maintenance challenges in the process .
Some of Maestro ’ s digital solutions to be featured on the booth include : n The Vigilante AQS™ : an air quality station that accurately measures airflow and direction , wet and dry bulb temperature , gas and air particulates ; reducing downtime and enabling miners to carry out a quicker and safe return to the working face while providing higher productivity . The modular design provides extremely flexible integration to any SCADA , PLC , DCS , PLS or HMI system , according to the company ; n The Zephyr AQS™ air quality station , which is a compact and low-cost monitoring tool . This solution monitors real-time environmental conditions and reports back to surface via Ethernet or an analogue connection to the network . This monitoring allows safer and quicker re-entry times after blasting , delivering worker safety and productivity improvements while reducing energy and GHG footprints ; n The MaestroFlex™ automated regulators . These regulators automatically adjust airflow from surface , as required , enabling manual or ventilation on demand software control . Controlling and directing air to the areas that require it – and reducing it to the areas without miners or operating equipment – also reduces energy costs and GHG emissions ; n The ModuDrive™ IIoT Ethernet actuator provides full feedback , health conditions and real-time diagnostics to allow troubleshooting from surface for maximum uptime and safety . A live demonstration of air flow control with the MaestroFlex regulator working with a ModuDrive actuator will be shown on the booth ; n Maestro ’ s network-based software platform , MaestroLink™ Server , will also be on show . This monitors equipment underground , providing real-time measurements and trending functions . The software manages the IIoT devices in the field using advanced edge-based diagnostic data , thereby reducing on-going calibration and maintenance operating costs ; n The SuperBrite™ Marquee Station . The world ' s only “ fail-safe ” LED display , Maestro says , displays real-time data or messages , providing underground operations with the air quality , equipment or personnel data they need on each level of the mine ; and n The Plexus PowerNet™ gigabit communication network , which provides data and power over a single coaxial cable . The Plexus will be delivering a high speed , low latency digital communication network providing PoE + power to the IP Maestro devices found on the company ’ s booth . The company also plans to reveal some “ exciting news ” on its product offering at the event .
Master Builders Solutions , a leader in providing reliable , customer- and applicationoriented chemical solutions focused and tailored to mining customer needs , plans to showcase several of its application-oriented solutions at its MINExpo 2021 booth .
This includes products and systems for rock bolting and anchoring , strata control , water control , chemical solutions for mine backfill , as well as the effective use and application of sprayed concrete in a virtual mine setting .
The company says it has a comprehensive range of products for early- and long-term strength in ground support , all tailored to suit specific site requirements and offer compatibility to local cements and “ excellent long-term durability ”.
“ Moreover , our innovations in alkali-free accelerators are a safe and essential part of modern sprayed concrete ,” Jim Lindsay , Head of Underground Construction , North America , Master Builders Solutions , said .
In addition to the availability of experts at its booth , Master Builders Solutions will allow MINExpo attendees to spray concrete via the Edvirt ® VR Shotcrete Simulator™ .
When it comes to injection solutions , Master Builders Solutions focuses on pre-injection to diminish unexpected water ingress and poor ground conditions . It uses micro cements and colloidal silica , as well as polyurethanes and polyurea silicates , to combat
water ingress quickly , and effectively consolidate ground .
“ With decades of experience in these chemical technologies , our injection experts will be at MINExpo to offer ideas and solutions for your toughest applications , including crack sealing , rehabilitation , ground consolidation , water stopping and water sealing ,” Lindsay said .
Master Builders Solutions intends to demonstrate the “ unique ” thixotropic behaviour of its MasterRoc ® RBA 380 product series for resin grouted bolting systems at the booth .
This fast-reacting , two-component polyurea silicate injection resin is used for rock bolt installations . With varying conditions underground – where rock temperatures range from -5 ° C up to 60 ° C – reacting resins cure at different speeds . Different pumping lengths require different set times .
The MasterRoc RBA 380 ’ s thixotropic behaviour allows for overhead applications without additional sealing , able to fill even the smallest cracks ( ≥0.14 mm ) over distances of up to 30 m .
“ The system is designed for higher mine efficiency , more efficient use of equipment , increased development rate and keeping miners safe during bolting operations due to its fast curing and strength development ,” Lindsay said .
Master Builders Solutions will , lastly , display its mine backfill solutions in Las Vegas .
Mine backfill is becoming increasingly important as mines go deeper , miners look to optimise ore recovery , as well as water recovery , while improving the mine cycle , optimising production and decreasing both the environmental impact and overall costs .
“ Master Builders Solutions takes a scientific approach to this challenge that can help mining companies understand and run backfill operations at lower risks and costs ,” Lindsay said . “ With over 30 years of experience in backfill , Master Builders Solutions has been a
