Abstract: Large-scale and high-efficiency development of coal-rock gas (CRG) is not only an important technological subject concerned in the unconventional natural gas area but also a challenging bottleneck for production business. Based on the deep coalbed methane production conditions both at home and abroad, this article makes a systematic analysis of the domestic CRG development demonstrative projects and draws three conclusions-high-efficiency development dominated by technological progress, management creation serving as the method and policy support acting as propelling power. From the three dimensions of geology, technology and economy, it also analyzes the main factors restricting high-efficiency CRG development, pointing out that the complicated geological conditions of CRG reservoirs lead to high development cost which is the bottleneck facing highefficiency development while the current production technology has certain limitations. Based on the five areas of technological progress, cost control, policy support, management improvement and joint venture and cooperation, the article comes up with 16 countermeasures for high-efficiency CRG development to promote sustainable CRG industrial development.
