Abstract: Aiming at the problems of large investment and difficult operation and maintenance in the construction of safety supervision information system of coal mine enterprises, a coal mine safety supervision platform with high availability, high concurrency and load balancing capability based on cloud services is built. This paper introduces the overall architecture and cloud service operation mode of the platform, and focuses on the technical systems in the platform design, such as edge layer data processing, cloud computing, data center construction, micro service architecture, multiple tenant systems, user request load balancing, etc. The coal mine safety supervision cloud service platform based on the micro service architecture realizes the access of coal mine safety production related system data and the transformation of business mode from selling products to selling services, reduces the initial investment and operation and maintenance costs of coal mining enterprises, and enhances the safety supervision ability of coal mines.
