Basic requirements for mining

I. Requirements for mining

(1) Ensuring the safety of mining work and good working conditions

Safe production and good working conditions are one of the important criteria for running a social enterprise. It is a prerequisite for normal production, especially for mining companies. It is produced under complicated and difficult conditions, thus ensuring the work of mining personnel. Safety and good working conditions are very important. This is one of the basic principles for evaluating the quality of mining methods.

(2) High labor productivity

Due to the complexity and cumbersomeness of mining production, the current labor consumption per ton of ore produced is large. It is even more important to adopt high-efficiency mining methods, use advanced technologies and processes as much as possible, continuously improve the level of mechanization, and fully mobilize the socialist enthusiasm of mining personnel to increase labor productivity.

(3) Large mining intensity

It refers to the mining speed of mineral deposits, well fields, stages and mining areas. Increase the intensity of exploitation, conducive to the completion and over-production tasks, reducing maintenance costs and production overhead roadway ensure that meet the needs of ore metallurgical industry growing. At the same time, speeding up mining is also an important measure to ensure safety.

(4) The loss and depletion of ore should be small

The loss of ore, that is, when mining metal deposits, some industrial reserves have not been produced due to various reasons, or the ore collected has not been transported to the surface and lost. The reasons for the loss of ore are as follows:

(1) Due to geological structural damage and hydrogeological conditions, the burial conditions of the ore body are complex and difficult to produce under current technical conditions;

(2) caused by the protection of the safety pillars left in important wells, rivers, etc. in the wellbore or on the ground;

(3) caused by the mining process;

(4) caused by the process of loading, transportation and unloading.

The depletion of ore is that the grade of the ore produced is lower than that of the original ore and becomes poor. The cause of depletion is due to the incorporation of waste rock, the loss of high grade ore and the leaching of certain metals. Depletion causes qualitative changes in the composition of the ore, resulting in significant economic losses.

If you only pay attention to the completion of the ore quantity, and neglect or even ignore the completion of the ore quality task, it may happen that the enterprise has completed the ore mining plan and failed to complete the concentrate or metal amount plan. Therefore, reducing depletion is also of great significance.

The basic way to reduce the depletion and loss of ore is to correctly select the development methods and mining methods suitable for the specific deposit conditions and their parameters and processes, correctly determine the mining sequence and reasonable process system, and at the same time, strengthen the production prospecting work. To accurately guide mine production.

(5) Reduce the cost of ore

Cost is a comprehensive performance of various work and is a comprehensive indicator for evaluating mining work. In mining production, reducing labor consumption, improving the quality of mined ore, increasing labor productivity, and reducing material and power consumption are the main ways to reduce costs.
