In-depth analysis of the mining service industry
2022/10/31
In recent years, the total amount of useful minerals mined in the world has been about 20 billion t, with an annual increase rate of 4% to 5%. Among them, hard rock is about 5 billion t, and the amount of ore mined underground is more than 1 billion t, mainly bonanza and useful minerals of higher value.Non-ferrous metal underground mines in our country account for about 89% of the total number of metal mines; except for the Ural Gold Mine, Cangshang Gold Mine and Zijinshan Gold Mine, which are open-pit mines, the rest are underground mines; although China's underground iron ore production accounts for only about 18% of the country's total production, from the layout point of view, the mines of some mining companies and iron and steel joint enterprises are almost all underground mining.In short, underground mining of metal mines will still play an important role in recent mining.
