How does Xinhai conduct ore mining research?

Xinhai Company is committed to providing one-stop mining engineering contracting + operation services (EPCM+O) for large, medium and small ferrous metallurgical mines, non-ferrous metallurgical mines, gold mines (including gold smelting), building materials and non-metallic mines, integrating geological exploration and consulting, design scheme customization (feasibility study report, preliminary design, and construction drawing design), equipment procurement and manufacturing, engineering construction and installation, mining engineering operation and management and other integrated services.

We have a professional mining research institute and mining design institute, which can provide consulting, research and design services for open-pit mining, underground mining, open-pit to underground mining, "three-down" mining, sand mining, and other mining needs, including industrial indicator demonstration, project proposal, feasibility study report, preliminary design, safety facility design, construction drawing design, rock mechanics experiment, and filling experiment.

Also, the company can design according to Chinese standards, Australian JORC standards, Valmin specifications and Canadian NI43-101 standards. It can also formulate preliminary prospecting or mining plans based on the geological exploration data of the mining area, and issue feasibility study reports, preliminary designs and construction designs. So How does Xinhai conduct ore mining research?

Xinhai Company conducted comprehensive geological exploration at the beginning of the project, including drilling sampling, geological mapping and geophysical exploration, to accurately grasp the distribution, scale and physical and chemical properties of the ore body, and provide data support for mining design and mineral processing technology. The company also tested the physical and mechanical properties of the filling materials and the mechanical indicators of the rock through laboratory experiments, such as filling experiments and rock mechanics experiments. It recommended engineering structure parameters and construction process parameters that are suitable for site conditions, while ensuring the safety and stability of the mining process and maintaining high construction efficiency, reducing the cost of engineering construction. On-site tests can also be carried out to optimize mining process parameters, ventilation systems and safety measures to better serve the safe and civilized production of mines.

1. Geological Exploration and Ore Analysis

Geological exploration covers geophysical exploration, geochemical exploration, survey, detailed investigation and exploration, including the construction of exploration projects and interpretation of results. The main work stages include prospecting exploration, geological prospecting, infrastructure and production prospecting, reserve verification and report writing. At the same time, it involves the exploration of sand mines (including tailings), engineering cataloging, sample collection, chemical analysis and results submission, providing comprehensive and detailed data support and technical basis for mine development.

At the same time, geological exploration work also includes drilling sampling and geological mapping to accurately grasp the distribution, scale and physical and chemical properties of the ore body. The grade analysis, mineral composition identification and selectivity test of the ore provide basic data for mining design and mineral processing technology.

2. Laboratory Test

2.1 Filling Test

Filling test is a process of changing the proportion of filling materials and testing their physical and mechanical properties to determine the best proportion of filling materials.

2.2 Rock Mechanics Experiment

Measure the physical and mechanical parameters of mining rocks, such as compressive strength, tensile strength, elastic modulus and Poisson's ratio, cohesion, internal friction angle, rheological and creep performance indicators of rocks, etc.

Through FLAC3D and other software, combined with test measurement indicators, stability analysis and prediction are carried out to formulate the optimal support structure and process parameters. Carry out ground pressure monitoring and stability analysis, providing a basis for tunnel support and mining field structure design.

3. Field test

3.1 Mining Method Experiment

Plan and design typical ore blocks, guide production on site, record the corresponding equipment, materials, electricity and energy, labor consumption and on-site loss rate, depletion rate, material unit consumption, work efficiency, safety performance, etc. in detail, provide data support for process comparison and priority, conduct simulation experiments of mining methods in laboratories or small test sites, and study the effects of different mining process parameters on ore recovery rate, depletion rate and stope stability. Optimize mining process flow and operating parameters, providing reliable technical support for industrial production.

3.2 Ventilation and Safety Experiment

According to the distribution of projects on site, use ventilation software such as VENTISIM or 3DVENT to perform three-dimensional modeling and network solution, simulate the mine ventilation system, and study ventilation resistance, air volume distribution and ventilation effect. Conduct experimental research on safety hazards such as fire, explosion and gas, formulate corresponding prevention and control measures, and ensure safe production in mines.

In the mining industry, accurate decision-making and scientific planning are the key to project success. Xinhai mining consulting services focus on providing customers with professional, detailed and forward-looking project proposals and feasibility study reports to help customers make wise choices in a complex mining environment.

When formulating the long-term development strategy and overall layout plan of the mine, it is necessary to comprehensively consider factors such as geological conditions, resource reserves, and market demand. Through a comprehensive analysis of the ore body, determine the reasonable mining scale, mining sequence and service life to ensure the sustainable use of resources and maximize the economic benefits of the mine. At the same time, optimize the mining technology and production process to adapt to market changes and technological progress to ensure the long-term and stable development of the mine.
