6 FAQs about [Uninterruptible power supply for coal mine hoisting system]
What is a power supply for a mining operation?
The concept of power supply for a mining operation, therefore, is one which provides for a reliable supply to the main distribution point in a mine, from which power is then distributed to all the key loads in the operation.
Does the extraction area of a coal mine have a high power supply?
The data show that the extraction area of a coal mine has a high power supply per production unit. At the same time, even at the rated load of the equipment, the consumption of reactive power is very significant.
Do you need a skid for a mines substation?
If it needs to be moved frequently over short distances, skids are preferred, especially if the 32 Electrical equipment and power supply systems for mines substation serves a continuously advancing face.
How to protect a mine from touch voltage?
In such systems some protection from touch voltage was achieved by means of neutral earthing. 54 Electrical equipment and power supply systems for mines However, even this voltage was not sufficient or economical for complete lighting systems, especially for roadways. Insulated network systems of 230 V were therefore introduced.
Should a 6 kV system be used in a mining operation?
The general conclusion is that, in a typical mining operation, a 6 kV system will cover practically all the immediate requirements of the major loads and of the pit supply network, for which, moreover, standard equipment is readily available.
How to reduce the cost of coal mining?
The power supply per mining equipment and the technological features of coal extraction significantly affect the cost of production. Therefore, it is necessary to pay special attention to the extraction area when developing energy efficiency measures to reduce the cost of coal mining.
