Mining in the engineering discipline is the extraction of minerals from underneath, above or on the ground. Mining engineering is associated with many other disciplines, such as mineral processing, exploration, excavation, geology, and metallurgy, geotechnical engineering and mining engineer may manage any phase of mining operations,from exploration and discovery of the mineral
Mining Fleet Achieves 100,000 Hours and Beyond. FreeportMcMoRan Copper and Golds Sierrita openpit mine is a lowgrade copper operation located in southern Arizona, USA, some 48 kilometers (30 miles) north of the Mexican border.
Equipment lifecycle cost analysis (LCCA) is typically used as one component of the equipment fleet management process and allows the fleet manager to make repair,equipment replacement, and retention decisions on the basis of a given piece of equipments economic life.
Custom designed gear units extend service life of mining equipment Renold Gears has recently worked closely with a major manufacturer of mining equipment to design heavyduty custom gear units that will provide longer service life for its customers and significantly reduce the cost of ownership by cutting downtime and maintenance.
This chapter presents various important aspects of mining equipment reliability including reasons for improving mining equipment reliability, open pit system reliability analysis, programmable electronic mining system failures, fault tree analysis of shovel machine, and dumper tyre reliability and factors affecting their reliability.
Over ten recent years the NNTs Gornoe Delo OOO has studied mining machinery and equipment operation practices of the largest mining companies in Russia and the CIS: SUEK OAO, UGMK OAO, Technique of equipment optimal service life estimation for
rate on an hourly basis over the life of the machine. Generally measured in hours, the MARC contract in an underground environment can run from hours. A guaranteed hourly rate enables the customer to track cash flows on mechanized equipment (often a significant contributor to overall mining operational costs) over the equipment life.
A product''s service life is its period of use in service. It is mostly used in nontechnical context, and has no scientific support or meaning. Several other terms more accurately describe a product''s life, from the point of manufacture, storage, and distribution, and eventual use.
#0183;#32;Effectiveness of the mining equipment is mainly influenced by the availability, reliability and maintainability of the system, and its capability to perform as expected. Reliability analysis techniques have been gradually accepted as standard tools for the planning and operation of automatic and complex mining systems since the mid1980s.

The global mining equipment market size was valued at USD billion in 2019 and is expected to grow at a compound annual growth rate (CAGR) of % from 2020 to 2027. Ongoing digital mine innovation is expected to transform the key aspects of mining over the next few years
for mining equipments due to following reasons: Mining is a serial operation of drillingblasting, loading, hauling and dumping. Therefore, the production of equipments used in each step depends on the production of previous equipment. That means utilization of each equipment affects the others. The capacity of mining equipment is huge.
Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to fill the gaps on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
Lifeofmine capital expenditure, inclusive of preproduction costs, mining capital development and sustaining property, plant and equipment (PPamp;E), but excluding closure costs, is estimated to be 235M (Table 6). The estimated annual capital expenditure profile is shown in Figure 5. Costs are as at September 2017.
Our Equipment Cost Guide is the most reliable source of equipment costs available to the mining industry. Estimators now have access to a convenient source of hourly operating costs as well as capital costs for virtually every piece of equipment listed in our previous guides.
The article describes the main points of the technique for the estimation of the economically feasible service life of equipment for surface mining operations. A case study is provided of the Tugnuisky opencast coal mine. Mining Industry Journal 1 2012,
Service life is based on a firm''s operational experience in supporting products. For example, a firm that has deployed solar panels for 20+ years gains an understanding of how long they last in the field in a variety of climates.
