Coalbed Methane Reserves in China.

Journal of Geography (Chigaku Zasshi), 2000
Coalbed Methane (CBM), a clean natural gas, has been expected to be utilized as one of the new domestic supply energy sources in China. The development of CBM in China has entered into a new phase, namely the execution of feasibility studies on exploration and production in particular areas, following the first phase of a general survey of CBM reserves.
