The Xinjie-Taigemiao Coal mine area, situated on the northeastern margin of the Mu Us sandy land, is affected by both climatic variations and human interventions. This region contends with water scarcity, and its ecological carrying capacity is approaching its saturation point. Notably, a considerable volume of coal mine drainage remains challenging to harness effectively. This study underscores the imperative of equitable water resource distribution in semi-arid regions where blue and green spaces coexist. It incorporates an understanding of the area's geological historical evolution, present natural geographical conditions, and potential subsidence due to mining operations. A foundational framework for delineating regional blue and green spaces is proposed. Employing comprehensive research techniques such as remote sensing image analysis and yearbook statistical data, this paper offers a systematic assessment of the components and characteristics of blue and green spaces within the regional sandy land-lake-grassland landscape. Special attention is directed towards the volume and quality metrics of mine water and its prospective comprehensive utilization. The study suggests strategies to ensure a balance between blue and green space supply and demand, bolster ecosystem resilience, and offers recommendations for refining spatial patterns. The overarching goal is to facilitate the conservation and judicious use of natural resources, enhance urban and rural habitats, and fortify regional ecological consistency. In doing so, we aim to pioneer a novel paradigm for ecological holistic management and resource utilization in semi-arid coal mining zones, fostering a harmonious relationship between mining and land development.
