Present status and prospects of coalbed methane development and utilization technology of coal mine area in China

The paper summarized the update progresses on the basic theory,technology and equipment, engineering demonstratior and others of the coalbed methane development and utilization in China coal mine area since the National 12 th Five Year Planning.The paper analyzed the present status and problems of the resource condit ion,gas drainage effect,uilization level and others in the coalbed methane development and utilization of China coal mine area.The paper pointed out that the coalbed met hane development and uilization in the coal mine should keep along a way of coordinative development,quality upgraded and production increased,tilization step by step. An integrated coordinative development of the coalbed methane and coal could be realized with the possible gas drainage operation and possible gas uilization.Therefore, the paper provided the technology and equipment requirements and development orientation in the enhanced gas drainage from the broken and soft seam,high efficient an d integrated transportation and utilization of the low concentration coalbed methane, special equipment of the coalbed methane development and utilization and others duri ng the National 13 th Five Year Planning.
