[Objective] Coal is the main energy source in China. Coalbed methane is one of important and dangerous fountainheads of coal mine production process and also an important clean energy. The main component of coalbed methane is methane, the greenhouse effect of methane is 80-120 times as the same volume of carbon dioxide. Massive emission of methane will seriously affect the quality of environment. Through analyzing the coordinated exploration of coal and coalbed methane patterns and technologies in China, this paper proves the necessity and flexibility of the coordinated exploration of coal and coalbed methane. After that, new technical approach to the cooperative exploration of coal and coalbed methane in China was proposed. [Methods] Based on the relative documents and literature, This paper analyzes and discusses the energy supply and demand, current situation and development trend of theories and technologies for coal and coalbed methane co-mining in China. At last, the development and utilization of coal and coalbed methane were studied and judged. [Results] The necessity and feasibility of implementing the coordinated exploration and development of coal and coalbed methane were scientifically validated and the main bottlenecks of coordinated exploration and development of coal and coalbed methane in China were revealed. Then this paper has established coordinated exploration and development of coal and coalbed methane technique system. At last, the new development mode, key technologies and development proposals of coordinated exploration and development of coal and coalbed methane were put forward. [Conclusions] It is very necessary and urgent to implement the coordinated exploration and development of coal and coalbed methane. The features of coalbed methane reservoir (low permeability, low reservoir pressure, low gas saturation), complex geological conditions and mining technical determined that the exploration and development mode of coalbed methane in China is dominated by cooperative exploration and development of coal and coalbed methane, supplemented by surface pumping. Under the carbon peaking and carbon neutrality goals. It is necessary to deepen the research on the law of reservoir forming of coal and coalbed methane coupling mineralization and accumulation, and establish a technical system combing the key technologies of coal and coalbed methane cooperative exploration, development and utilization with CCUS technology.
