How is granite mined from the mine?
Generally, the granite products we can see do not have colored stripes, only colored spotted patterns.
Many famous mountains in China, Gulangyu in Fujian, Luofu Mountain in Guangdong, such as Huangshan in Anhui, Lushan in Jiangxi, Taishan in Shandong, Taibai in Shaanxi, Keshiketeng Stone Forest in Inner Mongolia, Lushan in Liaoning, and Hengshan in Hunan, The appearance of granite landforms can be seen in Luhuitou in Hainan, Putuo Mountain, Mogan Mountain, Tiantai Mountain in Zhejiang, Gongga Mountain in Sichuan, Helan Mountain in Ningxia, and the Daxingan Mountains and Qilian Mountains.
The vast majority of deposits are mined by ordinary mechanized methods. Mechanized mining is further divided into open-pit mining (including ore and placer) and underground mining.
Open-pit mining strips the overlying rock layers of the ore body, and then the ore body is mined sequentially from top to bottom.
Open-pit mines can use large-scale mining machinery, with safer operations, less ore loss, low dilution rate, large production capacity, and low mining costs. This method is often used for large-scale poor iron deposits and building material deposits. Large-diameter granite saw blades and rubber wire saws match.
When the depth of the ore body is large, the thickness of the ore body is small, the stripping workload is large, and its economic benefit is lower than that of underground mining or the surface and landscape need to be protected, the underground mining method is used.
The mining process is roughly as follows: ore testing-ore separation-obtaining certificates-determining the beneficiation method-checking the site conditions-providing the beneficiation process flow chart-configuring the beneficiation equipment-site foundation treatment-equipment installation and debugging-normal production after trial operation-finished product sales .
Nature is always creating surprises and miracles for mankind. It may be just a piece of unremarkable appearance. With the country's permission, how do we mine and cut stone?
Granite is distributed in the continental crust, and basalt is distributed in the oceanic crust. The density of granite is significantly lower than that of basalt.
It is the extraordinary craftsmanship of nature that creates all the forms of granite.
When the sawing machine cuts it open, what suddenly appears in front of people is a strange texture like a landscape painting.
