In 2025, China's mining sector is demonstrating significant progress in green technology, achieving a harmonious balance between resource development and environmental protection through innovations in intelligent equipment, ecosystem restoration, and low-carbon operations.
? Intelligent Equipment Enhances Efficiency and Safety
The push for innovation has led to the development of intelligent equipment that makes mining operations safer, cleaner, and more efficient. Below are some of the recently recognized advancements:
Equipment / Technology Key Features / Applications
矿用多功能运载机器人 (Multi-purpose Mine Transport Robot) Developed by 华电煤业集团数智技术有限公司; aims to improve haulage efficiency and safety.
矿用单轨吊智能驾驶与调度一体化装备 (Intelligent Monorail Crane System) Developed by 尤洛卡（山东）矿业科技有限公司 and 淮南矿业; integrates smart dispatch and operation.
Full-process Intelligent Mining System Showcased by 中信重工; features unmanned transport and processing, increasing efficiency by ~50%.
Digital Twin Management Platform Used by 山东鑫海矿业; enables remote monitoring and control of entire mining and beneficiation process.
Major national research initiatives are also focused on creating integrated solutions. A key national project led by 紫金矿业 is developing "full-process, integrated, and optimized technology" for underground metal mines. This project aims to create a cohesive system from intelligent ore body detection and optimized blasting to smart rock transport and hazard prevention.
? Ecosystem Restoration and "Whole-Life-Cycle" Environmental Care
Moving beyond traditional "end-of-pipe" treatment, China is now emphasizing restoration throughout a mine's entire life cycle.
"Restoration While Mining": This approach, a new requirement under the revised 矿产资源法 (Mineral Resources Law), calls for同步 (synchronization) and 耦合 (coupling) of extraction and rehabilitation activities. As advocated by Professor Hu Zhenqi, this method can recover over 30% more land and significantly lower overall costs compared to post-mining cleanup.
Monitoring for Healthy Ecosystems: The focus of restoration is shifting from simple revegetation to ensuring the ecosystem is healthy and self-sustaining. Researchers are building advanced monitoring systems that use a combination of remote sensing, ground surveys, and intelligent platforms to track the long-term health and functionality of restored mining areas.
Diverse Models for Success: The Ministry of Natural Resources has promoted 30典型案例 (typical cases) that showcase innovative restoration models:
Anhui Huaibei Mining invested 13.6 billion yuan to transform subsidence land, turning "collapsed land into productive urban space.".
Xinjiang Koktokay repurposed historical mining relics into a global geopark, creating a model for tourism and education.
Zhejiang Huzhou used microorganisms to treat acid waste in abandoned mines, achieving ecological regeneration through "using waste to treat waste".
Specialized technologies are also being deployed for challenging environments. The China Coal Geological Administration has developed tailored solutions for the Yellow River Basin, including water-preserved mining tech and an integrated system for injecting waste into mining spaces to prevent ground subsidence and dispose of solid waste.
? Low-Carbon and Negative-Carbon Pathways
The industry is actively exploring technologies to reduce and even reverse its carbon footprint.
Clean Energy Transition: Companies are rapidly adopting clean energy. For instance, Zijin Mining has introduced electric mining trucks at its Xinjiang Wuqia mine, which now make up over 85% of its fleet. These trucks, powered by supporting photovoltaic projects, have reduced energy costs to about one-third of traditional diesel trucks, helping to create a "zero-carbon mine and low-carbon smelting" demonstration site.
Pioneering "Negative-Carbon Backfill Mining": A groundbreaking concept proposed by Academician Xie Heping's team at China University of Mining and Technology involves using a mixture of CO₂ and gangue (mining waste) to create a "negative-carbon" backfill material. This innovation not only safely stores CO₂ underground but also reduces the need for other filling materials, turning the mining process itself into a carbon sink. This technology is supported by 19 patent applications and is expected to be demonstrated in a project within three years.
? Global Impact and Future Outlook
China's green mining technologies are now providing viable "Chinese Solutions" for the global mining industry. Companies like Xinhai Mining and China Minmetals have exported their integrated intelligent solutions and digital platforms to over 100 countries and regions, including major projects in Zimbabwe and Peru.
The future direction is clear: continued integration of innovation, environmental stewardship, and global cooperation. With a strategic focus on intelligent equipment, full-life-cycle restoration, and breakthrough carbon-negative technologies, China is committed to a path of high-quality, sustainable mining development.
