What are the types of mines and what are their functions?
Mine refers to a certain mining boundary of natural resources, collection, independent production of business units. There are countless mining resources in the world, large and small. Mines can be divided into energy minerals, metal minerals, non-metallic minerals and water vapor minerals according to different form resources.
Energy mineral resources
In general, energy minerals can be divided into coal, oil, natural gas and geothermal resources. These energy minerals can provide different economic values for human society, such as coal, oil, natural gas can provide power for human production and life. Geothermal resources can be further processed and transformed into tourist attractions such as hot springs, providing economic value by hosting tourists. These energy minerals are an indispensable part, but these resources are non-renewable, if dried up, human production and life will be not a small impact, many industrial production will be stagnant, efficiency decline, people's travel will become difficult. In addition, if the unscrupulous use of these resources, will also harm the earth's environment, such as the destruction of the ozone layer and global warming, these hazards are irreversible. This is why many countries and regions are promoting green renewable energy.

Metal mineral
Some of the metals we are familiar with, such as iron, copper, aluminum, gold, silver and other metals, are obtained by mining metal minerals to obtain raw ore, and then the raw ore is smelted and processed to obtain high-purity metal. And turn these metals into tools that we use in our everyday lives. Most of the world's metal minerals are distributed in Australia, the United States and Africa and other countries, these metal minerals mining, promote national economic development, so some countries are more strict management of mine production, and introduced perfect laws and regulations. Moreover, with the development of science and technology, the difficulty of mining has been greatly reduced, and the efficiency has been continuously improved. At the same time, because of the improvement of laws and regulations, the owners of mines also pay more attention to the safety of workers.
Nonmetallic mineral
Non-metallic minerals refer to economically useful non-metallic elements, or a series of mineral resources that can be directly used. And the variety of non-metallic minerals, widely distributed. They are used for decoration or as additives to produce other products. Such as diamond, also known as diamond, its role is basically as a gemstone on the wedding ring, can also be made into a "glass knife", used as a tool.
The gems we commonly see in museums also belong to non-metallic mineral resources, which have a unique direct value in human society, but mainly play a decorative role.

Water vapor resources
Water vapor resources refer to the mineral resources existing on the earth in the form of liquid and gas, which is a very important economic precious resource with a very high value and can meet the needs of human society for resources. They are roughly divided into water resources and atmospheric resources, which can be exploited and used in the process of continuous emergence and formation, and play a role in human production and life all the time. The most common, such as water, is not only the source of human life, but also an indispensable part of production. Not only for most production, they can also be used to generate electricity, and contain rich minerals, such as calcium, magnesium, sodium, sulfur, chlorine, iron, potassium, phosphorus, etc., can be refined for other purposes. The atmospheric resources can be regarded as the air resources on the earth, the air contains 78% nitrogen, 21% oxygen and 0.9% other rare gases, of which the highest content of nitrogen has fertilizer value, has far-reaching significance for our production and life.
In short, any mineral resources are of great significance, and their discovery and utilization are conducive to the needs of human life and promote the economic and technological development of human society. However, the use of mineral resources also needs to comply with various safety measures, in the process of mining and use also need to pay attention to environmental protection. After all, the Earth is our home, and if the "home" is destroyed, what good is the discovery of more minerals?
