Introduction
The mining industry is one of the most important and vital industries to any economy. Regardless of the country, minerals and rocks extracted from the earth can be processed and given value, allowing the economy to benefit and expand. For any mining site, there is one necessary component that simply cannot be done without, and that is reliable electrical energy.
Without a reliable power source capable of meeting the needs of a mining site, the operations can suffer greatly. Thankfully, we are in a modern era, with different electrical supply options and power sources available. One of the most common and nearly ubiquitous electrical principle and solution used in mines all over the world is the mine power distribution system.
Background on Mine Power Distribution Systems
Mines look very different from one site to the next, but there are some underlying constants that are shared between all mine sites. Perhaps the most important and shared element of all mines is the need for a reliable power distribution system. Many modern mine sites and operations require large amounts of electrical energy, and a power distribution system is needed to supply that energy.
The need for electricity to power machines and electrical processes is not limited to the mine site. There are many auxiliary locations that need to access power, including mobile equipment, shafts, workshops, and offices. All of these locations need to be able to access an electrical power source and have it provide the necessary electrical current required by those machines and locations.
The Need for Reliability
Physical and electrical conditions for a power distribution system in a mine can vary significantly, but the need for reliable electricity remains the same. Many modern mines are travelling deeper into the ground for extraction of minerals and rocks. As these mines go deeper, the conditions become harsher. The electricity must be able to travel and provide service to all of the appropriate locations, regardless of these environmental conditions.
Power distribution systems for mine sites must be able to handle extreme weather conditions, including high temperatures, High humidity, and severe electrical disturbances, such as lightning strikes. This means that all of the components used in the distribution system must be of the highest quality, and be able to withstand these conditions. The power must also be able to travel safely and securely, so that the electrical current will not harm the personnel and machines being supplied with the power.
Unique Requirements of a Mining Power Distribution System
There are several unique requirements of a mining power distribution system, as compared to other industry power distribution systems. First and foremost, there is the need to run electrical lines and cabling through tunnels, caves, and shafts, which presents a challenge for any power distribution system. This must be done without compromising the safety of personnel and equipment.
Another challenge that is posed is the need for power to be sent over relatively long distances, underground. This often requires the use of special cables that are capable of transmitting power over the long distances, without deteriorating or losing power over time. As the mines get deeper, the power cables must go deeper as well, and this can present challenges for the design and maintenance of a power distribution system.
Conclusion
The mining industry is a vital industry in many countries around the world. It provides much needed resources and materials, and can be a powerful economic force. For any mine operation to run smoothly, it needs access to reliable electricity, and this is where the power distribution system of a mine site comes in to play.
In order to meet the unique requirements of a mine power distribution system, components and cables must be chosen and installed that are capable of withstanding harsh conditions and transmitting power over long distances. With the right power distribution system in place, mines can be supplied with the power they need to operate efficiently, and provide the necessary materials and resources for any economy.
