Empowering Mining Engineering: Xinhai Builds Green, Smart Mines

As the cornerstone of the mining industry chain, mining engineering is the prerequisite for subsequent links such as mineral processing and smelting. It covers the entire process from geological exploration to ore mining, serving as the core link in resource development.

In recent years, driven by the continuous guidance of national policies and profound changes in the market environment, the mining industry has stood at a new historical starting point. To promote the standardized development of the industry and realize the efficient and sustainable utilization of resources, countries around the world have successively introduced a series of policies, actively guiding the mining industry towards greening, intensification, and digital intelligence.

01Comprehensive EPC+M+O Mining Engineering Services

Xinhai Mining’s engineering services provide one-stop EPC+M+O mining contracting and operation services for large, medium, and small-sized ferrous metallurgical, non-ferrous, gold, building materials, and non-metallic mines.

By integrating geological exploration, customized design solutions (feasibility study reports, preliminary designs, construction drawings, etc.), equipment procurement and manufacturing, construction and installation, and mining operation management, Xinhai ensures smooth transitions between each process, reduces conversion costs, and improves overall mine efficiency.

02E - Mining Research and Design

Xinhai Mining has a professional Mining Research Institute and Mining Design Institute, which provide engineering consultation, experimental research, and design services for open-pit mining, underground mining, open-pit to underground mining, "Three-under" mining (under buildings, railways, and water bodies), and placer mining.

★ Mining Research

At the initial project stage, Xinhai conducts geological exploration and ore analysis, including drilling, sampling, surveying, geophysical and geochemical exploration, and detailed surveys.
These studies provide accurate data on ore body distribution, scale, and properties. Ore grade analysis, mineral composition identification, and beneficiability tests further support mining design and mineral processing solutions.

★ Mining Design

Xinhai’s Design Institute has a multidisciplinary team specializing in geology, mining, machinery, shaft construction, electrical engineering, civil structure, automation, and technical economy. With over 20 years of average experience, the team has completed design and consulting work for 300+ mining projects worldwide.

✦ Feasibility Study

Comprehensive assessment of resource reserves, ore processing performance, mining technical conditions, construction feasibility, and market prospects. Through technical and economic comparison of schemes, Xinhai provides optimized design plans and investment estimates that are advanced, economical, and safe.

✦ Mining Scheme

Design of development, preparation, and stoping systems based on ore body conditions. Supporting documents cover hoisting, ventilation, transportation, drainage, compressed air, filling, and power supply systems.

✦ Preliminary Mining Design

Based on the feasibility report, refine process configurations and technical schemes, and prepare a preliminary design report—a key document for engineering construction, equipment orders, and funding arrangements.

✦ Design of Mining Safety Facilities

Formulate safety systems, management structures, personnel assignments, supervision mechanisms, and emergency plans to ensure the project’s inherent safety.

✦ Construction Drawing Design

Provide construction drawings that comply with international standards across civil, electrical, water, and steel structure disciplines, ensuring engineering work can be executed directly based on these documents.

03P - Complete Set of Equipment Manufacturing and Procurement

Xinhai’s intelligent equipment manufacturing plant covers 110,000 m², integrating R&D, production, and quality control. It maintains a digital supply chain and mature supplier management system to ensure quality, quantity, and on-time delivery.

The company can supply complete sets of mining equipment for wellhead operations, hoisting, rock drilling, loading, transportation, drainage, ventilation, underground crushing, filling, and other major systems—along with spare parts and consumables.

04C - Mining Engineering Construction and Installation

Xinhai holds a Grade A qualification for general mine engineering contracting. Its team includes geological, surveying, shaft, mechanical, electrical, and safety engineers, along with architects and technicians. Equipped with advanced machinery, Xinhai is capable of executing large-scale and complex mine projects worldwide.

Construction personnel hold nationally recognized project management and safety certifications, as well as legal blasting licenses. With over 25 years of experience, the team provides:

✦ Mine Tunnel and Roadway Construction

Execution of shaft, roadway, and chamber excavation, support, and lining with advanced technology and equipment.

✦ Stope Development and Mining Operations

Implementation of stope mining tasks, including rock drilling, blasting, ore extraction, and roof management.

✦ Equipment Installation and Commissioning

Installation of mine hoists, pumping systems, main ventilation fans, underground crushers, electrical systems, pipelines, and cables—followed by operator training to ensure efficient operation.

✦ Construction Supervision and Quality Assurance

Establishment of robust management and quality assurance systems, progress tracking, and technical oversight. Regular technical briefings ensure full understanding of design standards and efficient execution.

05M + O - Mining Engineering Management and Operation

Xinhai provides comprehensive mine project management, covering construction, safety, and production phases.
Its experienced operation team offers services including mine operation management, production control, technical optimization, equipment maintenance, safety, and environmental management.

By combining geological data with mineral processing needs, the team formulates scientific mining plans to maintain the balance among three ore production levels, stabilize ore supply and quality, and control dilution, loss, and costs—achieving safe, efficient, and sustainable operations.

Building the Mines of the Future

Xinhai Mining leverages its professional expertise in mine engineering, currently managing projects such as the 4,000 t/d molybdenum mine in Hebei and the 500,000 t/a wollastonite mine in Jiangxi, delivering safe, stable, and sustainable operation guarantees.

Driven by the global shift toward green mining, Xinhai will continue to strengthen its technical innovation and full-industry-chain capabilities, helping global partners build efficient, environmentally friendly, and intelligent modern mines.
