This project addresses two serious environmental issues that occur worldwide. Firstly, it aims to develop strategies to combat underground coal fires which are a serious environmental problem. It has been estimated that underground coal fires in China alone contribute 2 to 3 per cent of the total world output of carbon dioxide (CO2) from burning fossil fuel. Concentrations of CO2 and CO (carbon monoxide) of up to 2200 ppm and 1000 ppm, respectively, have been measured in gases produced by underground coal fires. Secondly, the project is a proof of concept to validate the feasibility of production of geothermal energy from burning coal seams. This aspect has the potential to harvest large amounts of geothermal energy which is currently wasted.

该项目解决了全世界发生的两个严重环境问题。首先，它旨在制定战略来打击地下煤炭大火，这是一个严重的环境问题。据估计，仅中国的地下煤炭火灾就贡献了燃烧化石燃料的二氧化碳总产量（CO2）的2％至3％。二氧化碳和CO（一氧化碳）的浓度分别为2200 ppm和1000 ppm，已在地下煤火产生的气体中测量。其次，该项目是验证燃烧煤接缝生产地热能的可行性的概念证明。这一方面有可能收集当前浪费的大量地热能。
