mining equipments selection. This system is able to involve the expert knowledge in primary and secondary selection of equipment for surface coal mines [3]. In 1990, another expert system, in order to classify equipment, was planned in the open pit coal mine of Britain with the help of fuzzy logic.
MMME2104 Design and Selection of Mining Equipment Electrical Component Tutorial Sheet 3 Solutions 3Phase Induction Motors Question 1 (Problem 135 in the text) Why does the rotor of an induction motor turn slower than the revolving field? If the rotor turned at synchronous speed, then it would not experience a changing magnetic field hence there would be no current induced in the rotor

productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.
The design engineer should identify as many aspects that should be evaluated as possible, but only evaluate a dozen or fewer factors in equipment selection. Reviewing the big list frequently while limiting the number of parties involved provides good perspective on overall priorities, and many synergetic criteria are actually met by coincidence.
Mining operations and mobile equipment selection audit guide Page 4 of 22 1 Selection of equipment Selection of equipment Point Standard Guideline The mobile equipment is selected according to the limitations imposed by the site operating conditions. Intent: To ensure that new mobile equipment will be compatible with the site conditions.
#0183;#32;Design calculations establish minimum guidelines and requirements for generating electrical calculations on projects. Electrical calculations should be made for all projects that include electrical components and should be filed in the project notebook.

components; this knowledge leads the design engineer to consult numerous documents and technical catalogues. This electrical installation handbook, however, aims to supply, in a single document, tables for the quick definition of the main parameters of the components of an electrical plant and for the selection
#0183;#32;Component Selection process for costeffective and faster product design. Key points about the approach for choosing a particular component (electronic, electromechanical) by considering the operational specifications requirement in the least time have been mentioned in this article. Benefits of having a component database and rightly maintaining it helps to solve most of the product issues.
Mining machines continue to grow in sophistication and complexity. Regulatory requirements also have had to be incorporated into designs, which adds to the complexity of the machine. In many cases, little effort has been put into how the introduction of new technology to the machines affects the human operators of this equipment.

There are various basic electrical and electronic components that are commonly found in different circuits of peripherals. In many circuits, these components are used to build the circuit, which are classified into two categories such as active components and passive components.
In electrical and safety engineering, hazardous locations (HazLoc, pronounced haz#183;lk) are places where fire or explosion hazards may exist. Sources of such hazards include gases, vapors, dust, fibers, and flyings, which are combustible or flammable. Electrical equipment installed in such locations could provide an ignition source, due to electrical arcing, or high temperature.
Elimination of spark potential within components is accomplished by a combination of techniques starting with the electrical design and component selection. The most common method for protection is to limit electrical current by using multiple series resistors (assuming that resistors always fail open) and limit the voltage with multiple Zener diodes to ground (assuming diode always fail shorted).
Using electrical equipment on the job is always hazardous. According to a report prepared by the Fire Protection Research Foundation, there were 1,962 electricalrelated workplace deaths during the tenyear period ending in 200 of those occurred in mines. Compared with other industries, mining is among the most dangerous when it comes to working with electrical power.
