深层煤炭储量巨大,但由于高水压、高地应力、高瓦斯与高地温等原因严重地影响这部分煤炭资源的开发和利用。为此,新的煤炭利用技术的探讨和试验凸显出其重要性和意义。文章通过对地下煤气化技术(UCG技术)的优势、经济性评价、实际产品应用的分析和总结,得出煤炭地下气化技术具有较好的经济效益和环境效益,是我国洁净煤技术的重要研究和发展方向。 Deep coal reserves are huge, but due to high water pressure, high ground stress, high gas and high ground temperature and other factors seriously affect the development and utilization of this part of the coal resources. For this reason, the exploration and experiment of new coal utilization technologies highlight their importance and significance. Through the analysis of the advantages of UCG technology, economic evaluation and practical product application, the article concludes that coal underground gasification technology has good economic and environmental benefits, and is an important technology of clean coal in China. Research and development direction.
