Research and construction of coal mine equipment standard system

The research on the standard system of coal mine equipment is based on the top-level design of the standard system. Through in-depth review and analysis of the national and industry standards approved and published, the deficiency of the existing coal mine equipment standardization work is analyzed, focusing on the common characteristics of the European Union, the United States, Russia's coal mine equipment standards. In view of the existing deficiencies and the analysis of foreign standard systems for reference, the construction principles, construction dimensions and overall framework of the standard system were proposed. A standard system including basic standards of coal mine equipment, 12 sub-systems of professional equipment standards and 973 standards was established, and suggestions for standardization under the new system were put forward.
