Whitehaven Coal orders Caterpillar EL3000 Longwall Shearer
Press release--Whitehaven Coal’s Narrabri North mine set new production records last year and subsequently ordered a second Cat® EL3000 Longwall Shearer and a second Cat BSLPF6 Stage Loader for delivery in August this year. The mine, located in the Gunnedah Basin of New South Wales, Australia, set a weekly production record of 257,000 tons in June and a new quarterly production record in the final quarter of the year. The mine produced a total of 5.659 million tons in the year.
A Whitehaven production report summarized the longwall performance: “The longwall has been consistently producing coal at above the original design levels since production commenced in the second panel.” Full commercial production from the longwall started in October 2012, and production has increased steadily from that time. The EL3000 Shearer features a unique one-piece mainframe engineered to optimize productivity while ensuring reliability and durability. Ranging arms feature cast hinge points designed to handle higher cutting and haulage forces, such as 860-kW (1,380-hp) cutting forces with haulage capable of 32 m/min (105 ft/min) while cutting.
The new shearer and stage loader are scheduled to go into operation in Narrabri’s longwall block number 5, which is about 300 meters wide and will have an extraction height of 4.2 meters. Seam height is 8 to 10 meters, but Whitehaven determined that extending the longwall face—to as wide as 400 meters—will be more cost effective than would mining shorter face widths with longwall top coal caving techniques.
Both the first EL3000 Shearer and the new one are equipped with the Cat PMC Evo-S control system and advanced automation package. In 2014, Narrabri implemented full shearer automation, which boosted longwall productivity and horizon control. Utilization of full shearer automation—with no input from operators—is now exceeding 94 percent on average and is 95 to 100 percent except near gate ends.
Cat Advanced Automation Control uses state-based automation, which enables the shearer to operate precisely to the mining company’s defined production process, including direction of travel, speeds, arm height and ranging arm control modes. As many as 200 states are defined and specific actions and conditions must be met before the system enters the next state. The system is available as shearer automation only or as integrated longwall automation. The latter offers improved face alignment and horizon control, as experienced at Narrabri.
The greatest benefit to operators on the longwall face is the ability to stand clear of moving machinery and away from dust generation sources. The cutting process is consistent in speed and distance the shearer travels in and out of snakes—with no need to slow down to straighten or align the face as personnel control shields manually. Also, automatic horizon control delivers coal with less dilution from roof and floor material.
The new stage loader features Cat PF6 line pans, 42 mm power chain and a tensionable drive frame. Cat Slacktronic, the electronic chain slack sensor and control system, helps ensure reliable operation and long chain life.
WesTrac, the Cat dealer in the region, provides sales and product support services for Narrabri’s longwall operations.
Net zero benefits the mining industry and the environment
How do we get the world to net-zero faster?
Emitwise’s founders, Mauro Cozzi, Eduardo Gómez and Ben Peddie, approached a network of more than 100 of the world's largest enterprises and asked their CEOs, CFOs, and sustainability managers the big question: How do we get the world to net-zero faster? The challenge many shared was the lack of timely and accurate emissions data to enable strategic decisions. Companies often relied on annual audits of their carbon footprint for carbon accounting purposes. However, static yearly results were outdated upon publishing.
Emitwise saves companies an average of 260 working days a year by automating their scope 1, 2 and 3 emissions data. With the added benefits of clean audit trails and auto-populated accounting reports in line with GHG Protocol, all at the click of a button. Their easy to use solution enables businesses to quickly identify the carbon hotspots to target, and the precise real-time data empowers teams to remain agile and respond effectively, making achieving those goals possible.
Unique AI Technology
Emitwise’s unique AI technology empowers businesses to automatically measure, report and reduce their carbon footprint across their operations and supply chain, future-proofing companies for a zero-carbon world. It is the only solution that enables companies to fully automate their carbon accounting across all business units and suppliers, therefore liberating them from the drudgery of collecting and processing emissions data.
By using artificial intelligence to precisely measure emissions in real-time, businesses can identify and tackle carbon hotspots swiftly, enabling them to devise a trackable roadmap to net-zero carbon. At the same time, accurate audit trails and auto-populated annual reports ensure that companies comply with international reporting requirements, and align businesses with global climate targets to mitigate risk across their operations and supply chain.
The Oren Marketplace
Environmental management, social license to operate, safety, renewable energy to lower emissions and operational efficiency for mining can be supported by a range of digital solutions enabling dynamic operations. To address these issues, Shell and IBM joined forces to create the Oren Marketplace – the first B2B solutions platform for the mining sector.
With the adoption of many of the digital solutions offered through Oren, mining companies can adapt in real-time to risks or adjust plans ahead of a problem occurring. The goal is a shift towards proactive management as the optimal outcome for all stakeholders – community, shareholders, and employees.
Emitwise was founded with the goal of helping industries across all sectors reduce their carbon footprint. Similarly, Shell aims to become a net-zero emissions energy business by 2050, or sooner, in step with society and its customers. And Oren is focused on offering innovative products and services that can help mining companies track and reduce their emissions.
“Oren is the starting point for how we help our mining customers to de-carbonise,” explains Carol Chen, Global Lubricants Marketing, Vice President, Shell. “It’s our ambition to work with sectors like mining to help them find their own pathway to net-zero emissions through collaboration. The Oren marketplace offers a great opportunity for collaboration between the miners and technology companies that are joining this digital marketplace.”
Emitwise will be showcasing its vision for a net-zero future live from Lisbon at this year’s Web Summit. Bringing together the people and companies redefining the global tech industry, the online event welcomes 100,000+ attendees from around the world to hear from more than 800 speakers and view offerings from 2,500 startups covering a vast range of topics from Data Science and Climate Change to AI and Machine Learning.
