It allows mining, haulage and conveying systems to work at their most efficient rates to maximize mine production. The basic elements of each feeder-breaker are similar in design, following field-proven philosophies perfected over the years. Each machine begins with robust, all welded frame construction.
That history and independence combined with flexibility in engine design, a diversified product line up to 620 kW, options for cooling systems (air, oil, water) and customised engineering all mean that Deutz is a leading supplier to underground mining and a company that both small and large underground equipment OEMs can turn to.
coal quality up to 1761 kcal/kg using a production strategy based on maximum coal supply to the market10. Once a decision was made for quality improvement upon high selective excavation at the enterprise, it was then important to select suitable machinery/equipment and production methods that will result in the required coal quality improvement.
advanced countries very large equipment work round the clock. In India, the general tendency is to work for 16 hours a day and six days a week. In the mine under consideration, the equipment are planned to work for two shifts of six hours each. So the scheduled shift hours are 12 hours per day. 2.3. Machine Available Hours (MAH)

Mar 23, 2012· – Longwall mining is a special mining method with high productivity and smooth operation and the drum shearer is known as the most important component in longwall mines due to its direct role in the coal cutting and production process. Therefore, its reliability is important in keeping the mine production at a desired level. Hence, reliability analysis is essential in identifying and ...
SGS mining equipment maintenance (MEM) services help you reduce equipment downtime. This, of course, enables you to meet cost objectives and optimize profits in your oil sands mining operation. SGS is the trusted industry leader in oil sands mining equipment inspection and maintenance, fire suppression (FS) systems and HVAC (heating ...
Quintin O'Reilly, Equipment Sales Representative for Babcock, says that Atlantis Mining's recently purchased eight new R60D rigid haulers are the first to be sold in South Africa, and will be put to the test in rugged opencast coal mining conditions.
This approach is based on a system of mining and geometrical calculations, allowing carrying out an accurate selection of equipment and technology to adapt the use of hydraulic backhoes to ...
The traditional approach to maintaining mobile equipment - based on fixed interval component replacements and overhauls - is rapidly dying. In its place is a new framework for maintaining this equipment using Condition Based Maintenance approaches, and which focuses strongly on the consequences of failure.
The reliability analysis of the coal mining vehicle is expounded by the application of Reliability Centered Maintenance (RCM). According to RCM, maintenance mode and service period of the equipment are determined after a logical judgment and effective analysis of equipment reliability and malfunction results. Corresponding maintenance strategies are established.
however, for large-scale open pit mining in particular, the truck and loader" material movement practice is the preferred method of materials handling (Czaplicki, 1992; Ta et al., 2005). Throughout this paper, we consider a loader" to be any type of high productivity excavating equipment, which may include a mining loader, shovel or excavator.
Apr 01, 2008· To improve the reliability of mining machines, the most important measures requiring immediate attention are to grasp and remove the factors causing problems in all steps of the life cycle, such as planning, design, construction and maintenance, and to evaluate quantitatively the reliability model based on the failure history data.
Eickhoff mining machinery is well known for its reliability and robust design. Based on more than a century of experience in manufacturing mining equipment, gearboxes and steel castings, our Continuous Miners have proven their outstanding capabilities under the toughest conditions in coal mining.
study based on machine design and reliability characteristics is essential for improving. ... "Monitoring the reliability of coal face equipment", The Mining Engineer, Vol. 143, Z64, pp. 105 ...
Since mining is a very capital-intensive industry, it is more appreciate to use calendar time-based approach to estimate OEE. OEE for mining equipment OEE applications in mining industry differ from manufacturing industry. Therefore, it is necessary to develop equipment's own classification framework for the losses, which should be associated ...
