The preparation work before mining mainly refers to the ore body development project, the stripping project and the advancement project of mining excavation and trench preparation.
 
These three projects are generally carried out in sequence. Only with the conditions of synchronous progress can construction be carried out at the same time and the progress of the project can be accelerated.
 
Stone open-pit mine mine diamond wire saw development refers to the project of excavating the transportation road between the ground and each horizontal layer in a certain way, and establishing a transportation system connecting the quarry and the transportation ground.


 
According to the natural conditions of the ore body, stone mines mined by wire saws are generally developed by road transportation, development without cutting trenches, and joint development.
 
The stripping project mainly refers to the removal of the upper covering layer of the ore body and the surrounding surrounding rock, so that the bedrock is exposed and the formal mining is carried out.
