Abstract: Due to the rise of price of world oil and gas resources and serious environment problems, people again need choice in primary energy. Compared to nuclear energy, water and other renewable energy, people have to consider to the use of clean coal.Underground coal gasification is a best choice. Now Australia,The United Kingdom, South African and so on have made quikly important developments. They put the technologies for UCG-IGCC-CCS, UCG-AFC-CCS, UCG-GTL-CCS together and realise the really emission reduction. The facts show that underground coal gasification (UCG) have the lower cost, higher effeciency and friendly environment. Especially the fuel cell power station of the scale 500 MW is being built and hydrogen as the fuel provided by UCG and finally achieved the zero emission. UCG is a golden key or a solution to ensure the security of country's energy, the reduction of CO2 emission and enviorment pollution, and the safety of mine workers body. So UCG  should be the main direction of the primary energy for our country in the future.
