Some of the problems were existed in coal mining such as high cost, destroyed mining ecological environment and coal resource loosed. The power generation by using underground coal gasification technology can provide marked economic benefit and social benefit through demonstration project practice. It's a green environment industry model based on the technology and practice.

Methanol is similar with petrol in combustion and power properties. However, its emission is obviously lower than petroleum. The methanol synthesis technology has been very ripe and low-pressure process is more advance than traditional. Development direction of cool pipe tower, pipe shell tower, mix tower and combination tower is to enlarge their capacities on the world. Development the large capacity coal based synthesis methanol possesses very important realism significance in China for guarantee energy safety supply.

A kind of briquette was developed by using the Changzhi Ciilingshan meager coal and local production meager lean coal as raw material and two kind without drying binders and one drying type binder in laboratory. The briquette possesses high cold strength, good water proof and suitable for gasification process demand. About 300 t briquettes were production under industrial condition and it will put into industry gasification experiment for demonstration its characters.

A kind of activated carbon were made by using the different metamorphic grade Shanxi Datong coal, Ningxia Taixi coal and Inner Mongolia coal as raw material. The pore structure of them is analyzed by using N_2 and CO_2 on the full automatic absorption apparatus Autosorb-1C. N_2 isothermal absorption data was treated by BET equation and to calculate the special surface area. CO_2 isothermal absorption data was treated by DFT equation and to analyze the micro porous. The medium pore diameter distribution was calculated by BJH method. The result is shown that, micro pore and special surface area increasing, super micro pore and medium pore volume decreasing and average pore diameter tend to narrow in pace with metamorphic grade increasing of raw material coal. Obviously, the main effect factor on activated carbon pore structure is the raw material coal property.
