Electromagnetic Jigger Method
Electromagnetic jigger method is a method of coal mining in which a large magnet is positioned over specific coal layers, either manually or mechanically, and the resulting jiggle of coal around the magnet is separated and collected. This method reduces the risk of occupational accidents, energy costs, production, and environmental impacts.
Using this method, the mining process is drastically improved by reducing mining costs, enhancing the safety of miners, and limiting both short- and long-term environmental impacts from extractions. In addition to being safer, electromagnetic jiggering is also more efficient than conventional method. The magnet can separate coal with a purity of up to 96%. During extraction, coal does not have to be tilted or lifted, which reduces the number of workers needed in the resource and improves the extraction process.
The first use of Electromagnetic Jigger method was in Australia in the early 1980s. Since then, the method has become increasingly popular due to its increased safety, efficiency and lessened environmental impacts.
The advantages of Electromagnetic Jigger method include an efficient extraction, minimal energy needs and almost zero waste. The separation process is relatively simple and less labor intensive, making it an attractive alternative to traditional mining methods. Additionally, the machines can be moved easily, making it easy and cost efficient to set up a mining operation.
The biggest disadvantage of the Electromagnetic Jigger method is the need for a high degree of supervision. The machines need constant attention and need to be monitored to ensure they are functioning properly. Furthermore, there is a risk of overloading the machines, leading to costly breakdowns.
In conclusion, electromagnetism jigger method is an effective, low-cost and efficient method for coal mining. When compared to traditional methods of mining, it offers a number of advantages such as higher purity, less energy consumption, fewer miners required, and less environmental impact. However, the method requires high supervision and the machines must be regularly maintained in order to prevent costly breakdowns.
