The global requirement for skilled and experienced engineers to carry out independent validation of mining companies' compliance with the Global Industry Standard on Tailings management (GISTM) and other equivalent standards such as MAC TSM is growing, and the skills gap will only worsen when the new Global Tailings Management Institute (GTMI) comes into operation later this year, placing greater pressure on all mining companies to comply with the standards. However, technology can help here. The use of trusted, automated monitoring data management solutions can reduce the burden of calculation and compilation that is placed on engineers, freeing them up to carry out their more important role of engineering interpretation and guidance. #GISTM #GTMI #EngineerOfRecord #tailingsmanagement #digitaltransformation

𝐑𝐞𝐝𝐮𝐜𝐢𝐧𝐠 𝐅𝐥𝐲𝐫𝐨𝐜𝐤 𝐈𝐧𝐜𝐢𝐝𝐞𝐧𝐭𝐬 𝐢𝐧 𝐌𝐢𝐧𝐞 𝐁𝐥𝐚𝐬𝐭𝐢𝐧𝐠 𝐎𝐩𝐞𝐫𝐚𝐭𝐢𝐨𝐧𝐬 Mining operations are inherently hazardous, with various risks that can lead to severe accidents. One such risk is flyrock during blasting operations. Flyrock refers to rock fragments that are propelled beyond the designated blast area, posing significant dangers to personnel, equipment, and the surrounding environment. Ensuring safety in mining operations necessitates reducing flyrock incidents through meticulous planning, advanced techniques, and stringent safety measures.

Significant 107% Increase of Mineral Resource Ounces at Laverton Project. Magnetic Resources NL ASX:MAU, MD George Sakalidis “The Lady Julie North 4 Resource has been the prime drilling focus as reported in periodic releases to the ASX. It has multiple stacked lodes with a number of thick intersections that have not been closed off at depth. The initial deeper drilling started on the 25 January 2023 and has expanded in subsequent months to a 95-hole RC program for 16,356m. Drilling is continuing, with holes in excess of 400m depth, which is expected to increase the current resource at LJN4 of 13.1Mt at 2.02g/t for 852,000oz at a 0.5g/t cut off (Table 2). This LJN4 deposit sits within a regional structure called the Chatterbox Shear Zone that extends over a 12km length within the Magnetic tenements. This shear extends southwards of LJN4 and has had initial AC and RC drilling completed and some anomalous intersections that will be followed up with some shallow RC drilling for the purpose of finding further gold deposits. Drilling in the last 6 months included diamond drill holes for geotechnical evaluation of proposed pits, and for hydrology analysis. Project environmental, heritage and technical background studies are close to completion – optimisation and pit design has commenced on LJC and the expanded LJN4 – the aim is to prepare and submit a Mining Proposal in early 2024. Other strategic opportunities are also being investigated”.

Hexagon rolls out CAS at Oyu Tolgoi open pit Hexagon Mining has announced a partnership with Rio Tinto to deploy over 200 Hexagon AB #CollisionAvoidance Systems (#CAS) at the Oyu Tolgoi LLC / Оюу толгой ХХК #copper-#gold open pit mine in #Mongolia, including on the 30-strong 290 t class Komatsu Mining 930E-4SE haul trucks fleet as well as the loading tools which include two Caterpillar Inc. 7495HR rope shovels as well as Cat 6060 and Liebherr Mining R 9400 hydraulic shovels, plus a range of smaller class Komatsu and Caterpillar haul trucks, and in addition a wide range of ancillary machines. It is the first major CAS deployment in Mongolia, and Hexagon says its technology is now transforming safety and productivity at one of the largest known copper and gold deposits in the world. “The integrity of Hexagon’s product development is why we chose to build a partnership,” said Khorolsuren Ganzorig, Superintendent, Mine Support, #OyuTolgoi mine. “Since deploying CAS in our operation, I have noticed a drastic change in our operators’ driving behaviour. This will help to fulfil Rio Tinto’s and Oyu Tolgoi’s strong ambition to keep people safe in our mining operations.” Hexagon says it is dedicated to supporting the future of mining in Mongolia and is establishing a permanent presence there, adding: “This will allow us to fulfil a commitment to providing localised support for a growing partnership with Oyu Tolgoi and the broader mining industry in Mongolia.” Simon Stone, Hexagon’s Mining division VP APAC: “Any industrial operation faces challenges. Safety and productivity need to come together and be effectively managed. I’m sure that you can appreciate that in a world where’s 10,000 people working in the one facility, in the open pit and in the underground, 24 hours a day, 7 days a week – that is a challenge – the management and the leadership of the Oyu Tolgoi mine are very diligent in identifying risks and mitigating them. Hexagon is proud to be a partner.” He also referenced the fact that this is just the latest development in an already long term partnership between Hexagon and OT: “We have had our mine planning technology here for a long time; we have our particle size distribution cameras; we have our survey equipment [IDS GeoRadar] #GeoRadars – with the collision avoidance system rollout we are taking that safety proposition to a new level, making sure people go home safe at night to their families.” Munkhsukh Bayar, Project Manager, Oyu Tolgoi Mine gave some more details on the deployment: “Currently we have deployed the system at Level 7 and 8…we have installed the collision avoidance system on over 200 equipment units as well as training over 1,000 people since we started deployment. We have also started receiving some positive feedback from the operators…we see the support in how it is helping them do their work even more safely.” #futureofmining #mineofthefuture #minesafety

5222024 - Great meeting with Josef Bourgeois from HNTB, and Nicole from #CDC_NIOSH, also Steven Ulrich, PMP from #AAM -- setting out a plan for the inaugural meeting of the : ) - CDC/NIOSH enabled Forum on Mine Slope and Subsidence Monitoring - coming in #JUNE_12_2024. Join the NIOSH Mining Program (https://lnkd.in/drWgAX3r) for the first meeting of the Mine Slope and Subsidence Monitoring Partnership. This partnership investigates the use of existing stability/subsidence monitoring technologies in the mining industry and evaluates the potential for early instability detection design. NIOSH aims to create a space where industry, academia, and government collaborators can come together and discuss their successes, gaps, and needs within this area of study to facilitate safety benefits for mining and civil applications nationwide. https://lnkd.in/drWgAX3r For more information: CDC - Mining - Mine Slope and Subsidence Monitoring Partnership - NIOSH #monitoring_instrumentation #geomatics #landslides #geohazards #slope_stability.

Today we will talk about one of the most important underground mining methods Block caving method Described as the deep mining method of the future, the caving method is an underground mass mining method that allows the extraction of large quantities of relatively low-grade, vertically oriented large ore deposits. Advantages Fairly high productivity (range 14-36 tons/employee shift; maximum 36-45 tons/employee shift) The mining cost is fairly low, and it is the lowest underground method (relative cost 20%, such as longwall mining) Highest production rate for underground roads; Extensive method High recovery (90-125%), but dilution may be high (10-20%) The rock fracturing in production occurs entirely by caving, caused by undermining; No drilling and blasting cost (except secondary fracture) Suitable for gravity pulling or fully mechanical material handling: repeatable and uniform operations Ventilation is usually very satisfactory; Good health and safety (except undermining and some painting) Disadvantages Cave-ins and subsidence occur on a large scale with extensive damage to the surface Drag control is critical to the success of the method Development is slow, large-scale and expensive Maintenance of manifolds in production areas is significant and expensive if shafts are overloaded Rigid and inflexible method Hazardous work due to work stoppages in the gray and slush sub-levels and at intake points, with some risk of air blast throughout the mine. Possibility of spontaneous combustion in arc or rock during caving if withdrawal is slow or delayed (risk increases if sulfide content is greater than 45%) You can watch the video to get some additional useful information I hope you like this post thanks for this video Epiroc💛 #mining #miningengineering #mining #miningindustry #miningsolutions #undergroundmining #australia #canada #egypt #miningworldcup #blockcavingmethode #bhp #maaden #barrike
