Mining is one of the biggest heavy engineering industries to which many industries are dependent on. Be it the simplest utensils or the luxurious cars in one way or the other they are using metals that are mined.
People who are in the mining industry and its related industries will know a lot of details about mining. The common man will not have any idea about mining or its related things. For them to know more in this article, we will see some of the different kinds of mining.
Open pit mining
Open pit mining is one of the very common mining methods that are used for mining minerals or the ore that are present on the surface of the earth. The open-pit mining quarries can be 1000 meters deep. This kind of mining does not require any kind of tunneling. In this entire mining process, it is considered to be one of the simplest methods. The largest open pit mines are Fimiston Open pit and Newmont Boddington Gold Mine. Both of them almost measure 3.5km long and 1.5 km wide. Both are located in Western Australia.
Surface mining utilizes the massive strength of the Bucket Wheel Excavators that are capable of moving 12000 cubic meters of the earth in one hour. Surface mining is the process that is followed to mine the coals and the ore from the lands. In this process, the unwanted soil and other materials are removed completely. This is one of the problematic methods of mining because of the land decimation that occurs during the mining process. Surface mining results in infertile land and waste rocks. More than 70% of the mined land cannot be used for anything.
Underground mining is also called as the subsurface mining. It involves the digging of tunnels and shafts for executing the mining procedure properly. When compared to most of the mining methods, the impact that it has on the environment and the ecosystem is very less. To retrieve valuable materials, the underground mining professionals use shoves, axes and carts. It is a very risky job that needs a lot of training and concentration. The spot for underground mining is found the engineers and the geologists. Using the modern techniques, the levels of oxygen, toxicity levels and a lot of other things are found before starting the mining process.
In-suit mining is used to mine minerals. It is also called as the solution mining. It is a process that is used to pump some solutions into the ore body. The solution dissolves the ore and then it is extracted by pumping it out. This method is commonly used for the mining uranium. The solution that is pumped changes the Ph and oxidation levels of the ore. Now the ore breaks down which makes it easy for mining.
