Abstract:

With the development of Coal mining industry, much attention and effort has been paid to increase the utilization of gas. Baijigou coal mine, a high-gas coal mine, has taken advantage of gas since 1993. Being dewatered and pressured regulating by the pretreatment system, the extracted gas could be the material of Natural gas semi-reinforcing carbon black, on the other hand, it is able to support the need of heating and daily life of mining distraction. By the end of August 2011, the accumulated amount of used gas is 476 million m3, and the utilization rate of gas was 89.6%. The comprehensive utilization of gas at Baijigou coal mine not only protect the environment but also decrease the cost of resource, and at the same time, it could promote the developing of the step that gas transforms into a kind of new resource, which is of significant economic and social benefits. The success of gas utilization at Baijigou coal mine could be reference for other coal mines to take advantage of gas based on local conditions.

Key words: gas, comprehensive utilization, pretreatment system, carbon black
