Status and Development Orientation of Coal Bed Methane Exploration and Development Technology in China

The paper introduced the connotation of the coal bed methane exploration and development system and analyzed the present status and problems of th e coal bed methane exploration and development technology in China,including the coal bed methane resources exploration technology,the production improvement tec hnology of the coal bed methane surface well, the gas drainage technology of coal bed methane surface well,the mine coal bed methane drainage,coal and gas jointly m ining technology.According to the technical requirements of the coal bed methane exploration and development,the paper provided the study proposals on the coal bed methane exploration and the optimum technology of the favorable zone and block,the coal bed methane production improvement technology of the mediumhigh rank co al area mainly based on the Qinshui and Erdos basins,the coal bed methane well production improvement and the scale development technology of the low rank coal ar ea,the coal bed methane surface well development technology of multi seam and structure coal area,the short-term,medium-term and long-term planning of the coal an d coal bed methane joint mining technology.
