Annual funding

The annual production is the amount of useful mineral (good) extracted during a year in a mine , mining area , mining branch or country. The separate removal of mountains is not included in the annual production.

The annual funding is usually given in t . Every now and then the term “annual tons” is used.

Raw production

In the case of raw extraction , waste material, i.e. H. Contamination that is conveyed together with the goods is included. The calculation of conveyor systems, route cross-sections and processing systems of a mine are planned on the basis of the assumed raw production. ${\displaystyle F_{r}}$

Usable funding

The usable funding is the raw funding less the processing waste, the economically usable part of the total funding. It serves as a calculation basis for all economic matters. ${\displaystyle F_{v}=F_{r}-A_{a}g}$

Monthly and daily funding

The monthly and daily production of a mine are determined according to the same criteria as the annual production.
