Bridging Soft Coal Fines for Tailings Storage Closure – Australia Tailing dams store saturated mining by-products, resulting in a soft subgrade that poses challenges for construction machinery and personnel. Each of the three zones requires geotextiles with specific long-term design strengths (LTDS). Additionally, the materials supplied for each section need to be customized to cover the entire area to be capped. -Solmax https://lnkd.in/gYETSFBj #Tailings  #tailingsdam #tailingsstoragefacility #TSF

Did you know? Around 90-110 billion tons of material are excavated globally every year, with construction and mining at the top of the pile. The construction industry alone moves about 40-50 billion tons annually -think soil, gravel, and other materials moved to build roads, bridges, tunnels, and foundations for our cities and infrastructure. Meanwhile, mining digs up 50-60 billion tons, a big chunk of which is made up of construction aggregates like sand, gravel, and crushed stone (you know, the stuff we need to build things in the first place). Together, construction and mining account for 80% of the excavation industry. That’s a lot of dirt, and we’re moving it one ton at a time!

Surface Mining – Material to go As the name suggests, these beasts were initially utilised in the mining industry but from a civil construction perspective, these units make perfect sense in so many applications. A major advantage being utilised is the ability to effectively undertake excavation and crushing in a single pass with one machine. This eliminates the need for multiple pieces of plant, the requirement for a substantial footprint and lower CO2 emissions. Whilst it depends on the type of material being cut, the excavated material produced by the surface mining process can often be used as a fill or aggregate material for use on other areas of the site or transported offsite for any number of uses without further processing. There are a multitude of examples of excavated material from surface miners being used as the base or sub-base course on other road or civil projects where the material can be carted from one site to another, ready to be immediately used. #surfaceminer #terrainleveler #excavation #rockexcavation #benching #haulroad #rampexcavation #basementexcavation #declineexcavation #aggregate #cuttofill ACCIONA AU & NZ CPB Contractors CPBJH JV John Holland Bouygues Construction Australia Symal Group Ghella ANZ The Lane Construction Corporation

Crushing hammer has many functions, mining: mountain opening, mining, secondary crushing, grid sieve crushing; metallurgy: ladle, slag cleaning, furnace disintegration, equipment foundation demolition; construction: old building demolition, reinforced concrete crushing; highway: highway repair, cement pavement crushing, foundation excavation; railway: mountain opening, tunnel excavation, bridge section demolition, roadbed tamping; ship repair: hull declamping, derusting; other: ice breaking, permafrost, sand vibration tamping and other fields

Today, I had a visit to a limestone mine pit. This firsthand observation provided a deeper understanding of the large scale operations involved in limestone extraction. The well maintained tiered benches, the efficient deployment of heavy machinery, and the impressive capacity of the dump trucks were particularly noteworthy. One interesting observation was the disparity in perceived size of the dump trucks. While their height was truly significant when viewed at close proximity, they appeared much smaller from a distance. This highlights the vast scale of the mining operation. The visit provided a comprehensive view of the limestone mining process, fostering a greater appreciation for the complex yet essential work undertaken to procure this vital material. __________________________________________ First time seeing my posts?

Classifications for squeezing potential in civil tunnels and mines: The ground support strategies for squeezing rock conditions between civil tunnels and mining excavations are different. In civil tunnels we could manage large ground deformation during and after the construction phase of tunneling by installation effective and usually costly support systems such as steel arches or ductile tunnel linings with yielding elements incorporated into the shotcrete segments while applying such expensive support systems in mining are restricted and tend to considerable delays in mine development and production rate. Geometrically, compared to civil tunnels, mining tunnels are often small and in close proximity to other excavations. Mining typically occurs at greater depth than civil tunnels. therefore, complex and sometimes extreme, mining-induced stresses must be accommodated by the tunnel and its support system. Other important differences include the life time of excavations and convergence tolerance limits. In civil tunnels, the tolerance for deformation is low and strain greater than 10% considered as extreme squeezing problem, while in mining excavations, large deformation can occur and closure greater than 2m (40% strain) categorized as heavy squeezing ground.

Heavy excavators are incredible machines that represent the power of engineering and technology. They can move tons of earth with precision, reshaping landscapes for construction, mining, and infrastructure development. These machines are vital to modern industry, combining strength with versatility, as they can dig, lift, and transport materials in environments where manual labor would be inefficient or impossible. that is to show that our mine is well equipped for our gold mining

Wall Control Blasting: Enhancing Stability and Efficiency in Mining Operations Moss and Kaiser (2022) mentioned that wall control blasting is a specialized technique in open-pit and underground mining that aims to protect the stability of pit walls and other critical geological structures while ensuring optimal fragmentation. Singh et al. (2014) explained that this method involves carefully planned blast designs and sequencing to reduce over-break, minimize damage to surrounding rock, and prevent instability in mining walls. It’s especially critical in maintaining safety and extending the life of mine operations by reducing the risk of wall collapse or hazardous rock fall events. Key Advantages of Wall Control Blasting Enhanced Slope Stability: Regarding safety, minimizing excessive vibration and avoiding over-breaking, wall control blasting helps maintain the integrity of pit walls, preserving the slope's stability. This is essential for operational safety and prevents costly interruptions due to wall failures. Reduced Dilution and Ore Loss: Effective wall control reduces the mixing of waste and ore, which is crucial for maintaining high-grade ore purity and increasing the efficiency of subsequent ore processing steps. Improved Safety for Personnel and Equipment: Controlling fly rock and blast-induced fractures enhances the safety of personnel and equipment working near pit walls, reducing the risk of accidents. Extended Mine Life and Cost Efficiency: By preserving wall stability and reducing the need for additional ground support or rehabilitation, wall control blasting contributes to the mine’s economic sustainability, lowering operational costs over time. Environmental Benefits: Reduced ground vibration and fly rock protect nearby structures, ecosystems, and communities from blast-induced impacts, ensuring compliance with environmental regulations and social responsibility. Using WipFrag for Fragmentation Assessment in Wall Control Blasting To fully leverage the benefits of wall control blasting, it is essential to assess and monitor fragmentation accurately. WipFrag software, with its image analysis capabilities, provides a reliable solution for real-time fragmentation analysis. With tools like the specification envelope, WipFrag enables precise control over particle size distribution, allowing engineers to make data-driven adjustments to blast designs. This continuous feedback loop helps optimize blast results, ensuring that fragmentation goals are met while supporting wall stability and minimizing operational risks.
