⛏Longwall Coal Mining: Efficient Extraction Process Longwall coal mining is a highly productive method used to extract coal underground. It involves using advanced machinery to systematically extract large coal panels. Here's a brief overview: Process: Coal seams are divided into rectangular panels. Horizontal tunnels are driven into the seam for access. A longwall system is installed, including a shearer machine and roof supports. The shearer cuts the coal, which is then conveyed to the surface. Applicability: Longwall mining suits thick, continuous coal seams with limited complexities. It's used in economically viable underground mines. Advantages: High Productivity: Extracts a significant portion of coal within a panel, maximizing resource utilization. Improved Safety: Minimizes hazards for workers. Efficient Resource Extraction: Systematic and controlled extraction minimizes waste. Environmental Considerations: Subsidence control and advanced ventilation reduce impacts. Economic Viability: Cost-effective extraction of large coal reserves. Longwall coal mining offers efficient and safe coal extraction, making it attractive for large-scale operations. 🎥 Gregory Spiliotopoulos & RupertFX & Kikki’s Workshop YouTube Official Channel (YT) 🌎 Do you like it?

Thank you Sun Mining for facilitating last week's visit to Berau Coal. Main purpose was to observe the application of water gel in a coal mine and its potential for integration into our operations. I must admit, I'm thoroughly impressed. Here are a few standout benefits: 1. Water gel's have super low density (0.4-1) but it doesnt float in a wet hole. 2. With a 2.5 times increase in AN price over the past two years, water gel could serve as a cost-effective ANFO replacement. 3. Its adaptability for use in wet conditions. 4. High gas energy makes it particularly suitable for soft rock formations. 5.Low shock energy means we could reduce stemming length without risk of ejection Considering all these advantages, it's surprising to see limited usage if this product 🤔 To fellow blasting experts: I'm keen to hear your insights. What are the pros and cons of using Water Gel? Pak Beni Rasjid Thank you for showin me arouns too !! 😃

🚀 Enhancing Efficiency in Mineral Processing: The Key to Sustainable Mining 🚀 In today's world, the demand for metals is immense, driven by their necessity in household and industrial applications. To meet this demand, mineral processing, especially grinding and classification, is essential. Unfortunately, these processes are currently inefficient, leading to significant mineral wastage. Addressing this issue systematically is crucial for sustainable mineral processing. The Current Scenario: Global Mineral Demand: As global demand for minerals surges, processing remaining deposits becomes more challenging due to intricate mineralogy and the need to reduce energy consumption (Mudd, 2010; Calvo et al., 2022; Magdalena et al., 2023). Inefficiencies: Current grinding and classification processes are inefficient, resulting in substantial mineral wastage and energy consumption. Key Insights: Comminution and Flotation: Historically, these processes have been studied in isolation. Comminution focuses on achieving a specific grind size, while flotation aims to maximize grades and recovery. Enhanced Liberation: Shifting from achieving a target grind size to producing a size and liberation profile that maximizes flotation recovery is crucial. Poorly liberated minerals exhibit poor flotation performance, impacting the final concentrate grade. Role of Classification: Classification's Importance: Acts as a gatekeeper, redirecting coarse particles for further comminution while sending finer particles to the flotation circuit. Integrated Approach: Few studies have optimized the classification circuit to enhance flotation outcomes, despite the clear theoretical link between classification efficiency and flotation performance. The Way Forward: Operational Excellence: Leveraging advanced mathematical modeling and efficient design of grinding and classification systems can significantly improve recovery rates and reduce energy consumption. Sustainable Practices: Ensuring a sustainable and profitable mineral processing operation through optimized processes. By addressing these complexities, mineral processing engineers can significantly enhance the efficiency and sustainability of mining operations, ensuring that we meet the global demand for minerals responsibly. #MineralProcessing #SustainableMining #Comminution #Flotation #Grinding #Classification #EnergyEfficiency #MineralRecovery #MiningIndustry #InnovationInMining #AdvancedTechnologies #GreenMining #MiningEngineering #Sustainability #Metals #MiningCommunity Engage with this post and share your thoughts on how we can further enhance efficiency in mineral processing! ✨

Learn more about unlocking Tyrone's valuable minerals ⬇️ The third stage of modern mining is Rock Management. We've discussed the first two stages of mining in our previous posts. Be sure to give them a read! Our operations will mine two types of rock – ‘ore’, which contains metals, and ‘non-ore bearing rock’, which doesn’t. The project is designed to retain as much non-ore-bearing rock underground as possible. The remainder will be stored above ground in a Dry Stack Facility (DSF). Rock is first processed underground and transported to surface by an electric, covered conveyor for further processing. After further processing on surface, a concentrate containing the valuable metals will be produced and shipped overseas. The remaining rock from the processing is known as ‘tailings’. Over half of these tailings will be pumped back underground and mixed with cement to backfill cavities. The remaining tailings will have most of their water removed before being sent to the DSF. Traditionally, tailings would have been stored as a semi-liquid in ‘wet tailings dams’. By using the latest DSF technology, there will be no ‘wet tailings dams’ at Curraghinalt. Located in a natural hollow, the DSF is an engineered feature which will be progressively planted during operations, helping it blend into the surrounding area. Water draining from the DSF (typically rainwater) or any water which comes into contact with mine operations will be captured and either recycled within operations or treated in a state-of-the-art water treatment plant in line with strict regulatory standards before release. #ModernMining #StagesOfModernMining #Sperrins #DalradianOpportunities #EnvironmentalTechnology #BestPractice

The cleanup cost for British Columbia’s Elk Valley river, polluted by toxic materials from Teck Resources Limited’ coal mining activities, could amount to at least C$6.4 billion ($4.7 billion), as indicated by a report from the not-for-profit group Wildsight. The report commissioned by the Kootenay-based environmental organization underscores a substantial disparity between the $1.9 billion required by the province for Teck to reserve for emergency shutdowns and mine reclamation, and the projected expenses of the company’s initiatives to combat selenium pollution resulting from coal mining in B.C.’s Elk Valley. Selenium, a naturally occurring element toxic to fish in high concentrations, has been seeping for decades from waste rock piles surrounding Canadian miner Teck’s coal mines. #mining #coal #Canada

How do we Balance the Environmental & Social Impacts of the Development of Mineral Resources High grade iron ores will be required to enable a rapid transition to low carbon steelmaking in Electric Arc Furnaces using some iron produced by direct reduction with green hydrogen. Brazil Iron Ltd is a company registered in the UK that has plans to develop high grade iron ore in Brazil to produce green DRI. According to the company accounts for 2022 "The Total investments planned are in the order of 5 billion dollars, including the implementation of the mine, construction of the ore pipeline, ore terminal, pellet and iron briquette production plant. The study considered a production scale of 5 Mtpa of iron briquette for a period of 16 years. However the facilities are being designed to allow for future capacity expansion as well as an extension of the project's useful life. The start of the implementation of the project is scheduled for 2025." An article by Ione Wells, a South America Correspondent, Bahia, for the BBC outlines how some local residents oppose this development and that, "their fight against a UK-owned mining company is set to move to a top court in London." and that "There are 103 claimants now in the UK legal case, with claims spanning from 2011-2022." The BBC article reports that "Brazil Iron says by continuing it could create 27,000 jobs in its construction phase, 10,000 jobs permanently directly and indirectly, and save 2.35 million tonnes of carbon from being emitted every year in the steel industry supply chain." and that some local people support the development. The report suggests that "The key question, which is an issue playing out around the world, is whether such resources contributing to a greener future are hurting the environment and way of life locally." https://lnkd.in/edhCFAhu
