Conceptual distinction between ore fields and mine fields

The scope of all or part of the deposits that are classified by a mining enterprise, called the ore field. In a mining enterprise, it is classified into a group of mines or pits. According to the mine safety mining regulations, a mine must have at least two independent outlets. In addition to the main well responsible for ore upgrading, it is necessary to have responsible personnel and materials. The entire mine or part of the mine that is mined by the auxiliary well and the corresponding ventilation well is called the minefield. A field is sometimes equal to a mine field and sometimes includes several well fields.
According to this relationship, the minefield, minefield and mining area are divided into:
(1) An ore body classified as an open pit, called a well field;
(2) All deposits placed under a mining company mined ore field or part of call; (such as gold Ridge iron ore, gold and other Zhaoyuan)
(3) An ore body that is assigned to a company or mining bureau, called a mining area. (Northwest District, Central District, Southeast District) (such as Yangzhangzi Mining Bureau, Zhongtiaoshan Nonferrous Metals Company, etc.)
A mine field can include several well fields, and sometimes a mine field equals one well field.
