Introduction to the classification of mining methods

Mondo Social Updated on 2024-01-30

Classification of Mining MethodsMining method classification is an important concept in mining science, which divides mining methods into three categories according to the different ground pressure management methods during ore block mining: empty field mining method, caving mining method and fill mining method.

The open-field mining method is one of the most commonly used methods in mining, which uses an open field to contain the mined ore and uses certain technical means to transport the ore out of the stope. According to the different stope structures, the empty field mining method can be divided into several types, such as the comprehensive mining method, the room-and-pillar mining method, the reserved mining method, the sectional mining method and the stage mining method.

The caving mining method is a mining method that uses caving surrounding rock to achieve ground pressure management. It is suitable for ore bodies where caving is allowed on the surface, and the ore value is low and the dilution rate is not required. According to the different ways of caving surrounding rock, caving mining methods can be divided into single-layer caving method, layered caving method and segmented caving method.

The classification of mining methods is one of the basic theories of mining, and different mining methods have different scope and characteristics. In practical application, the appropriate mining method should be selected according to the geological conditions of the mine, the value of the ore, the mining scale and other factors. At the same time, with the continuous development of science and technology, new mining methods and equipment are also emerging, providing more options and possibilities for mining. Therefore, we should continue to learn and master new technologies and methods to improve the efficiency and safety of mining, and achieve both economic and social benefits.
