摘要

摘要: 地熱作為一種清潔環保的綠色能源，其有效利用是我國實現雙碳目標的重要方向之一。但在礦產資源開采，尤其是地下礦山向深部開發過程中，由于受地溫梯度影響，導致礦井溫度過高，成為制約礦山生產的重要因素，為維持正常生產，礦山多采取加強通風或人工降溫的方式進行處理。如何在礦山開發過程中將地熱資源變害為寶，實現資源開發利用的雙贏，是值得探討的難題。膠東是我國最大的黃金生產基地，也是我國東部地熱資源最為豐富的地區之一。該區地熱和礦產資源具有相似的動力來源和運輸通道，使二者在空間分布上具有高度重合性，諸多大型礦山不僅礦產資源儲量大，地熱資源也相當豐富，是最有望實現地熱與礦產資源共采的地區。在分析膠東地區地熱和礦產資源分布成因的基礎上，梳理了我國低溫地熱資源利用的現狀，認為膠東地區金礦資源埋藏和開采深度較大，建議對三山島、金青頂、新城、玲瓏金礦等利用相對成熟的低溫地熱供暖技術，治理礦山熱害的同時實現礦產與地熱資源的共采。

Abstract: Geothermal resources are renewable new energy sources. They have the characteristics of large reserves, wide distribution, good stability, and recyclability and are clean and environmentally friendly. Using geothermal energy represents a new direction for China’s sustainable development through achieving green, clean, low-carbon, and sustainable energy. After more than forty years of development, China’s geothermal industry, including power generation and heating, has made remarkable achievements and played an essential role in helping defend the blue sky and achieve carbon peaking and carbon neutrality goals. Metal mines, especially those with large mining depths, often contain plenty of geothermal resources. These deep mines often have a large amount of high-temperature rock mass or geothermal water. These resources have great mining and utilization values. However, during the mining process of mineral resources, especially in the process of deep development of underground mines, the mine temperature is too high due to factors such as geothermal gradients. The high temperature has become an important factor restricting mine production. To maintain daily production, mines often adopt enhanced ventilation or artificial cooling. How to turn geothermal energy into a usable resource in the process of mine development and achieve a win-win situation in resource development and utilization is a difficult problem worth exploring. The Jiaodong Peninsula is located on the continental margin where the Pacific plate subducts beneath the Eurasian plate. The Jiaodong Peninsula is the largest gold production area in China. Because of the preferable geodynamic setting, the Jiaodong Peninsula is also one of the regions with the most abundant geothermal resources in eastern China. The geothermal and mineral resources in the Jiaodong Peninsula share similar geodynamic settings. Therefore, the spatial distribution of geothermal and mineral resources is highly overlapping. Many large metal mines have large reserves of mineral resources and abundant geothermal resources. However, geothermal resources are often considered detrimental to underground mining activities. This paper analyzed the spatial distribution of geothermal and mineral resources in the Jiaodong Peninsula and summarized the current low-temperature geothermal resource utilization in China. The burial depth and mining of gold resources in the Jiaodong Peninsula are relatively large. Accordingly, it is recommended to use mature low-temperature geothermal heating technology to control the heat damage of mines and realize the co-mining of mineral and geothermal resources at gold mines such as the Sanshandao, Jinqingding, Xincheng, and Linglong gold deposits.
