The Rise of Mining Technology

To propose an optimal schedule to foremen, the instrument needs many working parameters from mobile machines. It is noted that there are normally travelling speeds and operating rates recommended by manufacturers for underground mining. It is ideal to obtain the working parameters by statistical analysis from historic data. In practice, it is also important to estimate working parameters by experienced operators. Mining technology equipment performance can be a function of mining conditions, moderated by availability and productivity considerations, or simply read from a table of measured performance. Mining technology consists of the tools, methods, and knowledge used to locate, extract, and process mineral and metal deposits in the earth. The methods used to locate ore bodies range from on-the-ground reconnaissance by prospectors to remote sensing techniques such as satellite imagery. Mine excavations take place either on the surface or underground.

Underground mining took place in both hard rock and placer deposits and used excavation, support, hoisting, ventilation, and drainage technologies. Early miners dug shallow shafts to reach the ore body, which they then followed to create "rat hole" or unplanned underground workings. Engineer-designed or planned underground workings became more typical by the end of the nineteenth century. Early excavations used hand drills and black powder. The late 1860s saw the invention of dynamite and the mechanical rock drill. They supported underground workings with wooden timbers, the best known of which is the "square-set timbering" invented in 1860, and unexcavated rock pillars or the "shrinkage" system by the beginning of the twentieth century. Early miners hand carried ore or used simple machines such as windlasses, whims, or small steam engines.

Ore processing technologies extract economically valuable minerals and metals. They include the collection of naturally occurring metals and minerals  (placer gold or lode silver), crushing and grinding ores, mechanical concentration of ores containing metals and minerals, and breaking down the ores with chemical, heat, and electrical processes. "Free milling" ores require the simplest processing technologies. Most metallic ore deposits are formed through the interaction of an aqueous fluid and host rocks. At some point along the fluid flow pathway through the Earth’s crust, the fluids encounter changes in physical or chemical conditions that cause the dissolved metals to precipitate. In research on ore deposits, the focus has traditionally been on the location of metal depositions, that is, the ore deposit itself. Interactive mining technology is aided by visual cues such as shadings by grade/quality ratio; current face positions highlighted within the 3D surveyed mine image and any other output, such as contours and 3D wireframes of the design. Face strings are automatically updated as mining progresses. Alternatively, batch scheduling and targeting using predefined sequences of mining may be used to quickly rank a choice of mining scenarios.

Mining companies are shifting their strategies and adopting new business and operating model than ever before. A combination of new mining technology, market volatility, changing global demand, radically different input economics, new locations in search of more reserves, a focus on a longer asset lifecycle and a commitment to operational excellence as well as policy shifts around the globe are all contributing to a seismic shift in the industry. To seize the opportunity, mining companies must leverage digital tools and capabilities to reach new levels of performance across the mining value chain. Digital mining technology allows today’s mining operations to reach new levels of performance from mine to market, across the whole mining value chain.
