The natural resources sector is fully dependent on the adoption of new technologies and closely integrated with the energy and utility sectors. As technology progresses, it brings with it a wide variety of alternative energy solutions (wind farms, solar cells power stations, hydroelectricity, geothermal energy or biofuel), while mineral and fossil natural resources are still fueling an energy-dependent economy.
Exploring new resource areas and developing new technologies are the most important drivers in the exploration, extraction, and industrial treatment of oil, gas, and minerals.
Looking at the manufacturing process for equipment and components, the natural resources industry is based on the same common workflows, from engineering to design, testing, production, and field installation. But the biggest differences can be found in the prototyping laboratory, where it is quite difficult to reproduce the real conditions from the field in testing. Just imagine how complicated the testing can be in real conditions for a high-volume mining excavation machine or a +10 km high deep drilling column.
The biggest and the heaviest mining machine in the world is the bucket wheel excavator from Bogatyr Mine, Kazakhstan . With a saw component with a 12-meter diameter and weighing in at 45,000 tons, this monster is capable of extracting more than 4,500 tons of coal per hour and needs to be operated by 27 miners.
The deepest drill hole in the world was located in the north of the Kola Peninsula . It reached 12km into the Earth’s crust during the 1980s. More recently, in 2011, Exxon Mobil recorded an even longer borehole at just over 12km in eastern Russia.
These are only two examples of incredible engineering performance in equipment. Any manufacturing process for extraction equipment should assimilate modern engineering and design solutions in order to reduce time, the risk of errors, and financial cost. Cloud-based CAD or CAE solutions allow real-time design corrections, dramatic cost reduction associated with physical testing of prototypes, and continuous improvement of product quality and performance.
By enabling companies to simulate extraction, transportation, and industrial process equipment, the SimScale simulation platform can play an important role in testing designs, making repeated changes, and increasing the overall efficiency. SimScale provides a full range of analyses, from structural mechanics and thermodynamics to fluid dynamics.
Mining equipment and heavy machinery, in general, are two areas where SimScale can make a real difference.

For centuries, we have been using the same exploitation processes for salt, coal, gold, and silver, or metallic minerals. The differences begin with mineral mass processing, which has specific extraction methodologies for each resource.
The US Bureau of Labor Statistics  divided the mining industry into five major segments: coal mining, gas, and oil extracting, metal ore mining, non-metal mineral mining and supporting activities, such as resource transportation. Each segment requires specific equipment, but there are several types of mining equipment that are used throughout the industry:
Real-time optimization for this mining equipment require specific analysis methods:
The SimScale Public Projects Library contains thousands of completed simulations for different applications which can be used as templates. Take a look at this wheel loader arm simulation, which is a static linear structural analysis. The results show the relative movement between the components and, at the same time, allow an assessment of the stress performance. Without any physical prototype, the design engineer can make improvements to the design early in the development process. Calculations were made to check which forces the hydraulic cylinders have generated to lift the applied load. The figure above shows the von Mises stress response of the analysis.
