Abstract: Aiming at the problems of regulatory duplication, information island and lack of trust mechanism in coal mine safety supervision and inspection, a multi-coordinated coal mine safety supervision model based on blockchain technology is proposed. Based on the decentrization characteristics of blockchain, the model effectively connects the supervision and inspection institutions, coal mining enterprises, coal miners and social organizations, so that any node can directly interact with the point-to-point information, and realizes the information sharing and co-management among the multi-subjects of supervision. Taking advantage of the characteristics of blockchain, such as open and transparent, traceable, and information can not be tampered with, a multi-collaborative coal mine safety supervision information platform based on blockchain technology is designed to ensure information authenticity, multi-party participation, intelligent supervision, and accurate accountability. This model innovates the way of coal mine safety supervision and inspection, explores the applicability and superiority of blockchain technology in coal mine safety supervision and supervision, and provides a new idea for the application of blockchain technology in coal mine supervision and other fields.
