Mining operations refer to various mining and production activities carried out in mines or mining sites. Mining operations cover all aspects of mine exploration, development, mining, processing, transportation, etc., aiming to convert underground or surface ore, ore sand or minerals into useful mineral products.
The process of mining operations usually involves the following key steps:
Exploration: Through geological exploration activities, determine the geological conditions of mines, judge potential mineral resources and reserves, and formulate reasonable mining plans.
Pretreatment: Including activities such as geological survey, sampling analysis and testing to understand the nature and quality of ore, and provide necessary data and information for subsequent mining and processing.
Development: According to the exploration results, select appropriate mining methods and mining equipment, and carry out mine infrastructure construction, such as roads, tunnels, mines, drainage systems, etc., to prepare for subsequent mining operations.
Mining: According to the development plan, use appropriate mining equipment and technology to mine and transport ore. Mining methods can be divided into two types: underground mining and open-pit mining. The specific methods include
1. Underground mining refers to a mining method in which underground ores are obtained by digging mines underground. The ore is stored in the gangues and veins excavated underground, and the miners take the ore out of the ground by entering the underground for drilling, blasting, tunneling and other operations. The main feature of underground mining is that it needs to be operated in underground space, which requires high safety requirements for mines and related equipment, and at the same time needs to solve drainage, ventilation, safety and other issues.
2. Surface planing is a method of mining ore on the surface. This method is generally applicable to situations where ore reserves are large, widely distributed, and ore beds are shallow. In surface planing, the ore is located in the rock or soil at the surface, and the mining process is mainly to remove the ore from the rock or soil by mechanical planing or blasting. The advantage of this method is high mining efficiency and relatively low cost, but because it is carried out on the surface, problems such as earthwork and environmental protection need to be dealt with.
3. Open-pit blasting is a method of crushing and separating ore using explosives in open-pit mines. The ore is separated from the rock by blasting operations for subsequent mining and processing. The process of open-air blasting usually involves multiple links such as selecting appropriate explosives, arranging fuzes, controlling blasting force, and ensuring blasting safety. This method has the characteristics of high ore crushing efficiency and good production benefits, but it also needs to strengthen the monitoring and safety measures of the blasting process to avoid environmental pollution and safety accidents.
Although underground mining, surface planing and surface blasting are three different mining methods, they all have their own advantages and disadvantages. In practical application, according to the geological characteristics, reserves, economic benefits, environmental protection and other factors of the ore, the most suitable mining method is selected to achieve the maximum utilization and sustainable development of mineral resources.
Processing: Crushing, grinding, and beneficiation are performed on the mined ore to extract useful metals, minerals or ore, remove impurities, and obtain high-quality mineral products.
Transportation: Transport the processed mineral products to processing plants, end users or export by transportation equipment (such as conveyor belts, railways, trucks, etc.).
Environmental protection and safety: Mine operations must comply with relevant environmental protection regulations and safety standards, take measures to reduce the impact on the environment, and ensure the safety and health of workers.
Generally speaking, mine operation is a complex and multi-link process, involving knowledge and technology in many fields such as geology, engineering, machinery, environment, etc. It aims to realize efficient mining and processing of mineral resources and provide necessary mineral products.
