About the mining process

The process of underground mine mining is as follows:
1). Exploration stage: Determine the existence and reserves of mineral resources. Geologists and exploration engineers use a variety of technical methods, such as geological surveys, geophysical surveys, and geochemical analyses, to investigate and evaluate potential mineral deposits.
2). Mining preparation stage: After determining the existence and reserves of mineral deposits, the mining preparation stage is entered. Mining companies will conduct detailed mine planning and design work, taking into account the geological conditions of the mineral deposit, the nature of the ore, mining technology and economic factors, etc., to determine the best mining method and mine layout. At the same time, environmental assessment and safety assessment are also required to ensure environmental protection and safe production during the mining process.
3). Mine development stage: Carry out mine development according to the mine design plan. It mainly includes excavation, blasting, support, ventilation, hydraulic and other projects. Excavation refers to the mining of ore bodies, which can be done in two ways: manual excavation and mechanical excavation. Blasting refers to the use of explosives to destroy ore bodies to facilitate extraction. Support refers to the support and reinforcement of ore bodies during mining to prevent mine collapse. Ventilation refers to ventilating the mine to ensure the safety of miners and the normal operation of the mine. Hydraulic refers to the hydraulic control of the mine to ensure the normal drainage and water supply of the mine.

4). Mine production stage: Mine production refers to the process of mining, beneficiation, smelting and other processes of ore to produce usable mineral products. Mining and dressing refers to collecting and separating ores to obtain ores containing target minerals.
The underground mine exploration stage requires a variety of equipment, including but not limited to the following categories:
1). Drilling equipment: including drilling rigs, drill pipes, drill bits, etc., used to drill holes in rock and soil layers to obtain geological samples and information.
2). Sampling equipment: including core samplers, rock cutting machines, etc., used to collect samples from underground rock and soil layers for subsequent geological analysis and evaluation.
3). Measuring equipment: including total stations, levels, theodolite, etc., used to measure surface topography, slope, altitude, etc., as well as the spatial distribution and shape of underground rock and soil layers.
4). Remote sensing equipment: Such as satellite remote sensing, aerial remote sensing equipment, etc., which can obtain large-scale, high-precision surface information for regional surveys of geological exploration.
5). Chemical analysis equipment: such as flame photometers, spectrometers, etc., used to analyze the content of elements and compounds in geological samples.
6). Geological radar: Measures underground structures through electromagnetic wave propagation and is used to explore underground hydrogeological conditions and rock and soil layer characteristics.
7). Rock and ore analysis equipment: such as rock ore chemical analyzers, microscopes, etc., used in laboratories to analyze the composition and properties of rock and ore samples.
The equipment required in the mine development stage includes various crushing equipment, mining equipment, transportation equipment and some auxiliary equipment.
Among them, common crushing equipment includes hammer crushers, impact crushers, cone crushers, jaw crushers, roller crushers, grinding machines, abrasive mills, etc. These equipment are suitable for crushing ores with different hardness and requirements.
Mining equipment includes rock drilling rigs, loaders and single-bucket excavators. These equipment are used for excavation and loading operations in mine pits.
Transportation equipment includes mining trucks, mining dump trucks, and conveyors, etc., used to transport excavated ore out of the mine pit.
Auxiliary equipment includes ventilation equipment (such as ventilators, hair dryers, etc.), drainage equipment (such as water pumps, water pipes, etc.), power supply equipment (such as transformers, generators, etc.) and safety equipment (such as helmets, safety belts, emergency lights, etc.). These equipment are critical to ensuring the safety and normal operation of mines.
In addition, in the mine development stage, the demand and application of automated intelligent equipment are becoming more and more extensive, such as automatic measurement and control systems for heavy media process parameters, CCS-type production centralized control systems and intelligent unmanned loading systems. These equipment can greatly improve production efficiency, reduce labor costs, and improve the safety and stability of mines.
