In mine construction, the mining project is the key link to realizing resource transformation, directly affecting the subsequent beneficiation efficiency and the overall profitability of the enterprise. However, the industry faces persistent challenges such as a severe shortage of proven reserves for mineable minerals, high dilution and ore loss rates, and the continuous rise in labor and equipment costs. These issues restrict production capacity and lead to delays in project timelines and uncontrolled operational expenses.
The keys to overcoming these difficulties lie in scientific design and precision project control, deploying professional teams and advanced equipment, and integrating mining construction with long-term resource planning.

01Industry Challenges: Ore Reserve Gaps and Operational Inefficiencies
Despite significant total reserves, many mining projects suffer from an imbalance between mineable and prepared reserves: the primary reserves (proven mineable quantity) and secondary reserves (prepared ore quantity) are not effectively connected. This often results in production interruptions during development due to reserve gaps.
At the same time, due to the absence of professional engineering teams or standardized construction management, the mining process suffers from high dilution and ore loss rates and excessive water usage during drilling and blasting, directly impacting mineral processing efficiency and project profitability.
Additionally, challenging topographies and deep-level mining conditions demand more advanced organizational capacity, equipment configuration, and geological adaptability. Mining service providers must offer multidisciplinary expertise and full-project lifecycle capabilities to address these challenges.

Ming Construction Teams: Each construction crew typically consists of over 100 personnel. A dedicated team of 60–70 workers is deployed for shaft sinking alone. All personnel in specialized roles—such as electricians, high-altitude workers, and certified blasters—are fully licensed and trained.
04Xinhai Mining Engineering Contracting and Operations: Case Studies
1. Jiangxi Province 500,000 t/a Silica Sand Mining Project
Xinhai Mining was awarded the contract for a 500,000 t/a silica sand project in Jiangxi Province, officially signed in 2024. The project spans a three-year contractual period with a total value approaching 100 million yuan. As the primary contractor, Xinhai is responsible for production mining operations and associated auxiliary engineering works at the site.
This project adopts a unit price-based contracting model, with pricing determined per ton of ore, enabling effective cost control and streamlined project management. Upon mobilization, Xinhai immediately commenced production mining operations while concurrently planning the development of new production drifts and tunnels—ensuring a smooth balance between current output and future expansion.
2. Hebei Province 4,000 t/d Molybdenum Mine EPC Project
Xinhai is currently engaged in an EPC (Engineering, Procurement, and Construction) contract for a molybdenum mining project in Hebei Province, featuring a designed processing capacity of 4,000 t/d. The operation involves a combined underground and open-pit mining process. The mining method utilizes medium to deep-hole bench blasting, providing high productivity and efficiency.
We conduct mining construction using engineering drawings from design institutes. Initially, it focuses on key infrastructure like shafts and ramps, with development lasting over a year before transitioning into full-scale mining.
In both projects, Xinhai fully leverages its professional capabilities in mine engineering, drawing upon extensive project management experience and efficient construction teams to ensure the coordinated advancement of mining and infrastructure works. This guarantees a seamless transition from construction to production, securing timeline adherence and quality assurance.
