Abstract: In view of the problems of lacking technical standards and imperfect standard system in China's CBM industry, the investigation and sorting of the status of CBM technical standards comprehensively are carried out in the paper. There are 87 current CBM standards (16 national standards and 71 industry standards), which are mainly management standards, followed by method standards, less basic and product standards. The framework of CBM factual standards system is determined. Based on the current situation of CBM industry and the demand of technical development at home and abroad, the standard system of CBM in China is constructed for the first time. The main specialties of the standard system are CBM geology and resource exploration, CBM drilling engineering, CBM hydraulic fracturing engineering, CBM drainage engineering, CBM surface gathering and utilization, and CBM surface extraction in coal mine area. According to the classification design of each specialty, 59 standards (13 national standards and 46 industry standards) are planned. The standard system and planning direction of CBM constructed in this paper highlight the key fields and technical status of CBM industry, which has certain scientificity, applicability and operability. It can provide reference for the standardization of CBM at home and abroad in the future, and has important research significance.
