In the arid landscapes of Xinjiang, where water resources are scarce and climate conditions are harsh, a groundbreaking study is paving the way for sustainable coal mining practices. Led by MENG Fanlin from Kuqa Kexing Coal Industry Co., Ltd., the research focuses on the hydrogeological structure of shallow-buried coal seams in wind erosion landform areas, with a particular emphasis on innovative water-retaining coal mining methods.
The Yushuquan Coal Mine served as the study’s focal point, where researchers meticulously examined the intricate water circulation patterns and hydrogeological structures unique to this region. MENG noted, “Understanding the hydrogeological dynamics is crucial for minimizing the environmental impact of mining activities. Our findings aim to protect vital water resources while allowing for responsible coal extraction.”
A key aspect of the research was the calculation of the height of the water-conducting fracture zone within the coal seam. This data enabled the identification of direct water-filled aquifers and facilitated the mapping of water-rich zones. The team also analyzed the hydraulic connections between various water bodies in the mining area, utilizing hydrological observation hole data to assess potential impacts caused by mining operations. The aquifers located above the coal seam and within the burnt rock formations have been identified as critical areas for protection.
To address the challenges posed by mining disturbances, MENG and his team divided the study area into three distinct regions, each requiring tailored water-retaining coal mining measures. Strategies such as retaining coal pillars and implementing limited mining heights were proposed to safeguard water resources. Furthermore, the study introduced a sewage purification reuse scheme aimed at enhancing water conservation efforts in the mining area.
The implications of this research extend beyond environmental protection; they also hold significant commercial potential for the construction sector. By adopting water-retaining methods, mining companies can mitigate water hazards and enhance the sustainability of their operations, ultimately leading to more efficient resource management. MENG emphasized, “The integration of sustainable practices in coal mining not only protects our environment but also ensures the long-term viability of the industry in regions like Xinjiang.”
As the construction sector increasingly prioritizes sustainability, the findings from this study, published in the Journal of Mining Science (矿业科学学报), may serve as a blueprint for future mining operations across arid regions. The innovative approaches outlined in this research could inspire similar studies and practices worldwide, promoting a balance between resource extraction and environmental stewardship.
