The equipment type in the same link should be as uniform as possible; 3 equipment parts supply and maintenance are reliable; 4 auxiliary equipment should be matched with main equipment; 5 personnel training is guaranteed; 6 equipment source is reliable. (3) The equipment can meet the production scale and the requirements for ore quality (selection and mining). (4) consider the sources of funding the purchase of equipment. (5) Consider environmental protection requirements. (6) Consider the economic and technical conditions around the mining area. Selection principle: (1) Technically feasible. (2) Economically reasonable. (3) Meet the mining scale and ore quality requirements.
