What voltage does a coal mine use?

Equipment with a nominal voltage of 1140 V appears in coal mines. In the 00s - 10s. of the 21st century, most coal mines have a high level of automation, there are automated control systems that allow you to control the main technological processes from the surface.

What voltage is used in a mine supply system?

Different voltages are used for mine supply systems in different countries, e.g. 2, 3.3, 4.4 and 5 kV, and up to 11 kV in non-gassy pits. For mines with explosive atmospheres the most appropriate voltage will be 6 kV.

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.

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.

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.

What is the future power voltage for major mine loads?

Thus, it may be anticipated that the future power voltage for major mine loads will be 1000 V. This solution is also very suitable for the transition period, considering the availability of equipment with two parallel windings which, connected in series, may be connected to a 1000 V network.
