Abstract: It was pointed out that cloud computation and platform technology was core of system of mine Internet of things. Technical objectives and main functions of the cloud computation platform of mine Internet of things were introduced. Key technologies of the cloud computation platform of mine Internet of things were expounded including platform architecture based on cloud interaction data pipeline, intelligent resource management and control model and load balancing algorithm, task scheduling and resource dispatching scheme, real-time and heterogeneous data exchange of mine, quick coding and sending in the batch of control command, quick data extraction and packing in the batch, and mine application oriented pushing. Research method and technical route of each technology were given. The paper lays a technical foundation for building a complete, advanced and universal cloud computation platform of mine Internet of things.
