In a significant advancement for the mining industry, researchers have unveiled a groundbreaking approach to water conservation in coal mining, particularly in shallow-buried, water-rich areas. This innovative technology promises to address the pressing issue of water resource depletion, which has become a growing concern in regions rich in coal seams. The research, led by Wen Luo from Guoneng Shendong Coal Group Limited Liability Company, highlights the dual challenge of efficient coal extraction while safeguarding vital water resources.
The western region of China, known for its abundant coal deposits, faces unique challenges due to the high intensity of mining operations. Traditional methods often compromise the integrity of aquifers, leading to severe water shortages that threaten both ecological balance and economic stability. Luo emphasizes, “By controlling the movement of rock strata, we can maintain aquifer stability and promote sustainable mining practices.” This perspective underlines the importance of integrating water conservation into mining strategies, which is essential for long-term viability in resource-rich areas.
The research introduces a three-dimensional water conservation mining system that aims to harmonize the extraction of coal with the preservation of water resources. By remaking the bottom water-blocking layer of the quaternary loose water-rich layer before mining, the researchers propose a method that effectively isolates water from mining activities. This innovative approach not only protects natural topography and surface vegetation but also ensures that mining operations do not exacerbate water scarcity issues.
Another key aspect of this research is the development of a new dual-use support system. This design allows for flexible switching between filling and non-filling operations, enhancing equipment efficiency and reducing operational downtime. “Our goal is to improve the adaptability of mining equipment while ensuring that we meet environmental standards,” Luo stated. This innovation could lead to significant cost savings and improved productivity, making it a game-changer for construction and mining companies looking to optimize their operations.
The findings were illustrated through practical applications at the Jinjie coal mine, where the proposed strategies were put to the test. The results demonstrated the effectiveness of the water conservation mining plan, showcasing a model that could be replicated in similar conditions across the Ordos Basin and beyond. The implications of this research extend beyond environmental protection; they offer a pathway for the coal industry to embrace green mining practices that align with global sustainability goals.
Published in ‘Meitan kexue jishu’ (Journal of Coal Science and Technology), this study not only highlights the technological advancements in mining but also sets a precedent for future research and development in the field. As the industry grapples with the dual pressures of resource extraction and environmental stewardship, innovations like those presented by Luo and his team could pave the way for a more sustainable future in mining.
