It has the advantages of low production cost, high production efficiency, and good safety. Underground mining was mainly underground mining. A few Kuangqu were open pit mining or open pit mining first, and then underground mining. Underground mining methods included vertical shaft, flat hole, joint development, and inclined shaft development. The specific mining method to be adopted depended on the topography of the deposit, the occurrence of the ore body, the scale, and the depth of burial.

The mining methods included underground mining and open-pit mining. Underground mining was the process of extracting ore from the ore blocks in the underground deposit. It was achieved through the mining, cutting, and extraction of the ore blocks. Underground mining methods included natural support mining method, artificial support mining method, and collapse mining method. Open pit mining was a mining method that gradually stripped the rocks and extracted useful minerals from the hillside or depression under open conditions. Compared to underground mining, open-pit mining had the advantages of faster construction speed, higher labor productivity, lower cost, better working conditions, safety, and higher ore recovery rate.
Open pit mining methods and methods
The mining methods of open-pit mines included mechanized mining methods and non-mechanized mining methods.
