Open pit mining
A method of extracting minerals from the surface of the earth using open-air mines.
Main technological processes of open pit mining:
Preparation of rocks for excavation. It includes the separation of rocks from the massif and their loosening. In case of rocks, it is carried out using drilling and blasting operations.
Loading of rock mass into vehicles. It is carried out using various lifting and transport mechanisms: excavators, loaders, rotary complexes, etc.
Transportation of rock mass.
Dumping.
Placement of waste rocks in dumps, planning of dumps, their reclamation.
In this fashion, I presented what I could do. This is not a career in the understanding of the word, you have to do it. Such places of mining are available on the "deposit" of stone, and you decide what to extract there. Important!!!!!! You can build both stone and coal, iron or uranium. You decide. Of course, you will only mine ore, it needs to be taken for processing.
The productivity of 2.5 tons, less than the Quarry (made on its basis), but they can be put quite close, if you correctly arrange the productivity in general, it will be more than the mines (there is a zone around the mine where it is not possible to put a second one, refused this, and on the stone looks better in my opinion).
Visually, you can easily build a quarry, load ore to concentrating plants, and from there, through my Bulk Cargo Loading Station, redistribute both for sale and for the needs of your Republic.
