(1) Ensuring the safety of mining operations and good working conditions
Since mining production is carried out under complicated and difficult conditions, it is important to ensure the safety of workers' equipment, facilities and the entire mine. Ensuring a good working environment is an important principle for evaluating the quality of mining methods.
(2) Labor productivity requirements
Due to the complexity and heavyness of mine production, the current labor consumption per ton of ore is relatively large. Therefore, it is very important to adopt high-efficiency mining methods, adopt advanced technology and technology, continuously improve the mechanization level of mine production, and strengthen the scientific management of enterprises to improve labor productivity.
(3) Continuously increase the mining intensity
Increasing the mining intensity is conducive to completing and over-compensating the country's production tasks, reducing the maintenance costs and production management costs of the roadway. It is also one of the important measures to ensure the safety of work.
(4) Depletion requirements for ore loss
Loss of ore is a waste of national resources and increases the cost of ore. Two ore will increase transportation costs, improve costs, the real yield beneficiation and final product costs, enable enterprises to reduce production of the metal.
(5) Lowering the cost of mines
The main ways to reduce the cost of ore are to reduce labor consumption, increase the quality of ore produced, increase labor productivity, and reduce material and labor consumption.
