地下煤气化技术的发展与应用

The Development and Application of Underground Coal Gasification

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。

The reserve volume of deep coal seams is huge, but the development and application is affected by some factors, such as the high water pressure, the high crustal stress, the high gas and the high earth temperature. Therefore, the research and experiment of efficient coal technologies is irreplaceable important and significant. The advantages, economic evaluation and product application of UCG are analyzed and summed up. It draws a conclusion that UCG are both economically and environmentally attractive. It will be an important research topic and the development directions in the field of clean coal technology.
