Caterpillar has for many years used telemetry as a key component in the data acquisition and analysis systems used to test and develop heavy equipment. The testing of construction and mining equipment at Caterpillar presents several unique challenges, such as the operating environment of the test machine, the large number of models in the product line, the need to change test machines on a dail...

Purpose. To develop methods for spatial control over ultrasonic cleaning by using phased array of radiators. simulate the process developed to prove their effectiveness. Methodology. Application as a basic radiator enables redistribution intensity in bath increasing it most contaminated zones cleaned object. Geometric and physical laws provide analytically defined parameters beam. Findings. The...

There is a strong push within the mining sector to automate equipment such as large excavators. A challenging problem is the control of motion on high inertia degrees of freedom where the actuators are constrained in the power they can deliver to and extract from the system and the machine’s underlying control system sits between the automation system and the actuators. The swing motion of an e...

This paper reviews the 100-year history of federal electrical safety research in the U.S mining industry, originally by the US Bureau of Mines, and as carried on today by NIOSH. First, there is a brief historical review of the use of electrical power in mining and an examination of the associated shock, fire, and explosion hazards. These hazards were the impetus for government intervention to i...

A key factor enabling the achievement of the required capacity by longwall mining systems is to obtain a satisfactory service life for individual components of such systems. Such components include right-angle planetary gearboxes for armoured face conveyors. An increase in the service life of such equipment can be achieved by ensuring adequacy in terms of design, materials and organization. As ...

To ensure the production/output and customer satisfaction in mining sector the estimation of Remaining Useful Life of mining machineries is a prime. In this paper we used the reliability analysis in order to estimate an optimal mining equipment repair/replacement policy by estimating their remaining useful life. The proportional hazard model was used in reliability analysis to be realistic and ...

Considering the unfortunate skill of English teaching posts, this paper advances plan strategy for postcapability assessment framework in light data mining, further develops equipment arrangement, upgrades activity cycle and capability programming, builds postability framework. At long last, it is affirmed by tests. The view mining has high practicability during time spent down to earth applica...

Accident databases (NRC, RMP, and others) contain records of incidents (e.g., releases and spills) that have occurred in the USA chemical plants during recent years. For various chemical industries, [Kleindorfer, P. R., Belke, J. C., Elliott, M. R., Lee, K., Lowe, R. A., & Feldman, H. I. (2003). Accident epidemiology and the US chemical industry: Accident history and worst-case data from RMP*In...
