Surface mining machines problems of maintenance and modernization

The economics of ground control and reliability analysis have not been fully integrated into traditional mine production management This paper demonstrates how an approach using a maintenance methodology can be applied to assess the reliability of underground mining excavations The approach is also applicable to surface mining excavations

Implementation of experimental method of determining modal characteristics of surface mining machinery in the modernization of the excavating unit Autorzy Rusinski, E

Glencore Mine Takes Maintenance to a New Level Because of these conditions, underground maintenance and repair shops often are not held to the same standards as surface mines But one underground mine decided to change this perception, building a worldclass maintenance shop underground and following best practices for contamination control As

In an up market or a down cycle, one things for certain: the worlds continued appetite for the products of surface mining Were there through every market fluctuation, mitted to bringing you the products, services, technologies and expertise that help you do more while spending less

hydraulically driven but a certain number of drills used in mining operations remain pnmatically driven for various reasons Handheld rock drills and DTHs are almost invariably pnmatic Current factors impeding a plete conversion to hydraulic drilling include the remaining lifetimes of ex isting equipment, maintenance issues, initial

EFFECTIVE MAINTENANCE PRACTICES FOR MINING EQUIPMENTS DrDPTripathy Department of Mining Engineering NIT, Rourkela769008 Abstract: Maintenance represents a significant proportion of the overall operating costs in the mining industry Despite the large cost of maintenance, management has only given passing attention to the optimization of the

Jul 31, 2019 The typical surface mine quarry has lots of specialized equipment, and each piece has a name that new miners may not be familiar with To help you get up to speed fast, weve provided a list of mon surface mining equipment, along with images and

machine or its element should be in operation before being replaced or renovated During overhaul, key elements of the machine, which are not scheduled for replacement or repair, are often inspected If defects, excessive wear, etc are found, a decision is made to perform corrective actions

Power and mining industry characterizes with mon use of the machines and installations that size and mass exceeds the machinery and equipment used in majority of industries Due to the scale of those objects, the objects dynamics and external loads characteristics prises with low frequency, low cycle loads of large energy

Getting on and off of machines and equipment, and machine maintenance and repair tasks were also among the most hazardous activities reported Getting on and off of machines and equipment often led to falls injuring the knees or ankles, likely as a result

The details of this approach with respect to measurement techniques and methods of data analysis are demonstrated on the example of the modernization of excavating units of SchRs 4600 wheel excavators The SchRs 460050 Fig 1 and SchRs 460030 Fig 2 bucket wheel excavators are used in

Machinelearning algorithms can be coded into fixed plant control systems eg DCS and PLC and mobile fleet edge processing solutions, such as iVolvesMaintenance Manager, which is capable of running machinelearning algorithms on the machine or using cloud processing
