Chinacoal Xinji Energy Company Innovatively Applied the Technology of Fast Excavation of Coalbed Methane into Production
 

Chinacoal Xinji Energy Company innovatively applied the technology of fast excavation of into production. Through drilling holes at laneways and pumping high-pressured nitrogen into coalbed, the gas circulation pace in coalbed was fastened, and the gas in the coalbed was driven out, thus the gas content inside the coalbed was decreased, and the fast excavation of was effectively realized. The application of the technology provides safe and reliable assurance for the excavation of gas at coal mines, and which is very important to the prevention of coal mine gas hazards(Chinacoal Xinji Energy Company).
