A Management Specification for Big Data Sharing in Smart Mine

With the rapid advancement of the informatization process of the coal industry, applications based on the Internet of Things and intelligent processing technologies for smart mines have sprung up. The sharing and aggregation of various colliery automation system data is the core foundation for the realization of intelligent mine applications. The resolution of integrity and real-time issues in data sharing determines the availability of upper-level intelligent applications. This paper proposes a set of smart mine specifications. It regulates coal mine data sharing behavior from three perspectives: data collection, data transmission, and data storage. The data source specification specifies the protocol for data collection and transmission. The evaluation indicators and governance methods are described in the data quality specification. It sets data reliability sharing standards based on the characteristics of each business system. The labels defined in the data storage specification model realize the efficient management of data indexing which can be used by professional and non-professional users in the coal industry. We constructed an experimental system based on real measured data from a certain colliery. The system can collect, manage and store the data from various automation systems following the specifications.
