2.Main content
（1）Mine construction: including geological exploration, mine design, planning, design and construction of systems such as roadway excavation, mine ventilation, drainage, power supply, hoisting and transportation.
（2）Mining operations: According to the occurrence conditions of ore bodies and mining technologies, appropriate mining methods are selected, such as filling mining method and caving mining method for underground mining, as well as stripping works and mining-stripping works for open-pit mining.
Gold mining and smelting
（3）Construction of surface engineering in mining areas: It involves the construction of surface facilities such as ore dressing plants, tailings ponds, mining area roads, railways, transmission lines, and communication facilities.
（4）Mine safety and environmental protection: including mine safety management, disaster prevention and control (such as gas, water damage, fire, etc.), and environmental protection (such as wastewater treatment, waste residue treatment, ecological restoration, etc.).
3.Application Fields
（1）Energy mineral development: The mining of energy minerals such as coal, oil, and natural gas is an important application field of mine engineering. For example, coal is one of the main energy sources in China. The continuous progress of underground and open-pit mining technologies has improved the recovery rate and mining efficiency of coal resources.

（2）Metal mineral development: The mining of metal minerals such as iron ore, copper ore, and bauxite provides raw materials for industries like steel and non-ferrous metals. Underground mining technologies such as the filling mining method and caving mining method are widely applied in metal mineral extraction. Meanwhile, open-pit mining technologies continue to evolve, enhancing the mining efficiency and resource recovery rate of metal minerals.
（3）Non-metallic mineral development: The mining of non-metallic minerals such as limestone, quartzite, and fluorite provides raw materials for industries like building materials and chemical engineering. In the mining of non-metallic minerals, mine engineering focuses on optimizing mining processes and comprehensively utilizing resources to enhance the added value of non-metallic minerals.
4.Safety Management
（1）Establish and improve the safety management system: Formulate safety management systems, clarify the safety responsibilities of management personnel at all levels, and establish a safety responsibility system. Carry out regular work safety inspections, set up a special safety management department, and allocate professional personnel to be responsible for safety management work.
（2）Strengthen safety training for employees: Regularly carry out safety training and drills to enhance employees' safety awareness and emergency response capabilities. The training content should include safety operation procedures, precautions for equipment use, emergency rescue knowledge, etc.

（3）Improve the risk assessment and early warning mechanism: Before mining, organize expert teams to conduct comprehensive risk assessments, identify potential safety hazards, and formulate targeted preventive measures. Establish a monitoring system to carry out real-time monitoring of hazardous areas and provide timely warnings.
（4）Strengthen equipment maintenance and management: Formulate equipment maintenance plans, conduct regular inspections and maintenance of equipment, promptly replace old components, and avoid safety accidents caused by equipment failures. At the same time, establish an equipment operation record system to ensure that operators strictly follow operating procedures.
Mineral Exploration
（5）Optimize the ventilation and dust control system: During mine operations, rationally design the ventilation system to ensure air circulation in the working environment. Equip professional dust control equipment to reduce dust concentration and protect the health of employees. Regularly detect the air quality in the mine to ensure compliance with safety standards.
（6）Improve emergency response plans and drills: Formulate detailed emergency response plans covering countermeasures for various sudden accidents. Regularly organize emergency drills to enhance the emergency response capabilities and collaborative combat capabilities of all employees. After the drills, summarize and analyze existing problems, and promptly revise the emergency response plans.
5.Technical Progress
（1）Intelligent and automated technologies: Through 3D modeling (such as Dimine, Surpac), the Internet of Things, big data, artificial intelligence, and automation technologies, remote monitoring, automated mining, and intelligent scheduling of "smart mines" are realized. For example, the application of 5G communication technology makes the communication between mining equipment more stable and efficient, and the use of equipment such as driverless mining trucks and intelligent mining robots improves the production efficiency and safety of mines.
Open-pit mineral mining
（2）Green mine construction technologies: Adopt environment-friendly mining technologies, closed conveying systems, tailings management and land reclamation plans to reduce environmental impacts. For example, filling mining technology can minimize surface subsidence and tailings discharge, wastewater recycling technology can conserve water resources, and ecological restoration technology can restore the ecological environment of mines.
（3）Deep mining technology: With the gradual depletion of shallow mineral resources, deep mining has become an important development direction of mine engineering. Deep mining is faced with challenges such as high ground stress, high temperature, and high osmotic pressure, requiring the research and development of new support technologies, ventilation technologies, cooling technologies, and mining processes to ensure the safety and efficiency of deep mining.
（4）New energy development: Mining technologies for strategic minerals such as lithium, cobalt, and rare earths.
