The whole process preparation and staffing of mines from infrastructure construction to commencement

Mine development is a complex system project. It needs to go through multiple stages from preliminary preparation to formal commencement, involving geological exploration, planning and design, administrative approval, infrastructure construction, equipment procurement and installation, and personnel organization and deployment. Scientific and reasonable preparation and perfect staffing are the key to ensure the smooth commissioning and efficient operation of mines. This article will systematically introduce the whole process preparation and staffing plan of mines from infrastructure construction to commencement.

I. Preliminary preparations

1. Geological exploration and resource assessment

- Preliminary exploration: regional geological surveys through satellite remote sensing, geological mapping, etc.

- Detailed exploration: use drilling, trenching, geophysical exploration and other means to determine the ore body shape, scale and grade

- Resource reserve estimation: calculate inferred resource volume and proven reserves according to international or national standards

- Ore selectivity test: conduct laboratory scale and small-scale continuous tests to determine the mineral processing process

2. Feasibility study and project approval

- Technical feasibility analysis: evaluate mining methods, mineral processing technology, equipment selection and other technical solutions

- Economic feasibility analysis: calculate economic indicators such as return on investment and net present value

- Environmental impact assessment: prepare an environmental impact assessment report, predict the impact of the project on the environment and preventive measures

- Safety pre-evaluation: identify potential safety risks and propose preventive control measures

- Project approval: submit an application to the Development and Reform Commission and other departments to obtain project approval

3. Administrative approval and license processing

- Mining rights application: apply to the natural resources department to demarcate the mining area and apply for a mining license

- Land use approval: apply for construction land planning permission and land use right certificate

- Safety permit: apply for a safety production license from the emergency management department

- Environmental protection approval: obtain environmental impact assessment approval and sewage discharge permit

- Other permits: including water extraction permit, explosive material use permit, etc.

II. Design and construction preparation stage

1. Preliminary design and construction drawing design

- Overall mine design: determine key parameters such as development system, mining method, production capacity, etc.

- Ore dressing plant design: including process design such as crushing, grinding, selection, dehydration, etc.

- Tailings pond design: determine storage capacity, dam type, anti-seepage and flood discharge system

- Auxiliary facilities design: including water supply, power supply, ventilation, mechanical repair and other system design

- Construction drawing design: provide detailed construction drawings and technical specifications

2. Construction preparation and infrastructure construction

- Site leveling: carry out earthwork to create conditions for subsequent construction

- Temporary facilities construction: build temporary office area, living area, material storage yard, etc.

- Road construction: Construction of internal roads and external connecting roads in the mining area

- Water and electricity access: Set up temporary power supply lines to solve the water problem for construction

- Communication system: Establish a temporary communication network to ensure construction communication

3. Equipment procurement and installation preparation

- Selection of major equipment: Determine the models and quantities of key equipment such as mining, transportation, and mineral processing

- Procurement bidding: Prepare bidding documents and organize equipment procurement bidding

- Equipment supervision: Supervise the manufacturing process and quality inspection of important equipment

- Installation plan: Develop large-scale equipment installation plans and safety measures

- Spare parts preparation: Purchase necessary spare parts and consumable parts

III. Staffing plan

1. Management team configuration

- Senior management: 1 mine manager/general manager, 1 deputy mine manager in charge of production, safety, and technology

- Middle management: Including heads of departments such as production scheduling, equipment management, and safety management

- Grassroots management: On-site management personnel such as workshop directors and team leaders

2. Professional technical team

- Geological team: 2-3 geological engineers, responsible for resource management and production exploration

- Mining team: 3-5 mining engineers, responsible for mining design and production planning

- Mineral processing team: 2-3 mineral processing engineers, responsible for process control and optimization of the processing plant

- Electromechanical team: 2 mechanical engineers and 2 electrical engineers, responsible for equipment maintenance and management

- Surveying team: 1-2 surveying engineers, responsible for mine surveying

3. Production operators

- Mining operators: including drillers, blasters, shovelers, transport drivers, etc.

- Mineral processing operators: crushers, grinders, flotation operators, dehydrators, etc.

- Auxiliary operators: maintenance workers, electricians, welders, laboratory technicians, etc.

- Special operators: personnel who need to hold certificates for crane operation and pressure vessel operation

4. Support and guarantee personnel

- Safety and environmental protection personnel: full-time safety officers, environmental protection managers

- Administrative and logistics personnel: personnel in personnel, finance, procurement, warehousing and other functions

- Medical and health personnel: equipped with necessary medical staff and emergency facilities

IV. Preparation and acceptance before construction

1. System debugging and trial operation

- Single machine debugging: no-load and load test runs of main equipment

- Linkage test runs: test the coordinated operation of various systems

- Trial run with materials: full process test using actual ore

- Process parameter optimization: adjust operating parameters to achieve design indicators

2. Safety facility acceptance

- "Three Simultaneous" acceptance of safety facilities: ensure that safety facilities and main projects are designed, constructed and put into production at the same time

- Fire acceptance: check whether the fire protection system is complete and effective

- Occupational health acceptance: evaluate the control of occupational disease hazards in the workplace

3. Personnel training and assessment

- Pre-job training: including safety knowledge, operating procedures, emergency response, etc.

- Special operation training: special training and assessment for personnel who need to hold certificates

- Simulation drills: organize accident emergency drills to improve emergency response capabilities

- Assessment and posting: only after passing the assessment can you officially start work

4. Start-up conditions inspection

- Data preparation: organize various technical data, operating procedures and management systems

- Material preparation: check whether the raw materials and spare parts required for production are in place

- System inspection: confirm that each production system has the conditions for normal operation

- Construction approval: submit a construction report to the regulatory department and officially start production after approval

From infrastructure to construction, the mine is a systematic project that requires scientific planning, careful organization and strict management. Only through perfect preliminary preparation, reasonable design and construction, and sufficient staffing can the mine be smoothly put into production and achieve safe and efficient operation. With technological progress and management innovation, the mine construction process is moving towards a more intelligent and green direction, which puts higher requirements on project preparation and personnel quality. Mining companies should continuously optimize the construction process, improve the professional level of personnel, and lay a solid foundation for the long-term and stable operation of mines.
