| 中文摘要: |
| 山西省煤炭资源丰富，年煤炭产量占全国产量的近1/4，煤炭资源开采形成大量的采空地下空间。随着碳中和目标的提出和山西风电、光伏发电的大力发展，如何合理利用煤矿采空地下空间，尤其是将地下空间与新能源结合将成为煤炭产业低碳发展的关键。本次研究运用比例系数法和采空地下空间守恒定律，测算出2022年山西省开采煤矿井巷可利用空间为1.54亿m3，“十五”到“十三五”期间关闭/退出煤矿的井巷可利用空间为1.05亿m3，估算1949至2021年山西省煤矿因工作面开采形成的采空地下空间约38.98亿m3，预测到2030年山西省煤矿工作面开采还可形成采空地下空间约19.56亿m3。根据山西省能源低碳发展需求提出了山西省煤矿采空地下空间未来可利用的四种模式：煤矿地下旅游或地下仓储、煤矿地下抽水蓄能、煤矿地下压缩空气储能和煤矿地下封存二氧化碳等。 |

| Shanxi Province contains abundant coal resources, with its annual coal output occupying nearly 1/4 of the national output, and has formed a large amount of underground space due to coal mining. With the proposal of the goal of carbon neutrality and the vigorous development of wind power and photovoltaic power generation in Shanxi, it is critical to make rational use of the underground space, especially the combination of underground space and new energy for the low-carbon development of coal industry. This work used the proportional coefficient method and the law of conservation of underground mining space, estimated the available space of coal mines in Shanxi Province of 2022 to be 154 million m3, and the space of those closed coal mines from the 10th to 13th Five-Year Plan was 105 million m3. Also, the underground space formed by mining working faces in coal mines of Shanxi Province from 1949 to 2021 was estimated to be 3.898 billion m3, and the space of mining working faces in coal mines will be about 1.956 billion m3 by 2030. According to the demand of low-carbon energy development in Shanxi Province, four modes of underground space utilization in coal mines were put forward, i.e., underground tourism or underground storage, underground pumped energy storage, underground compressed air storage and underground carbon dioxide storage. |
