To solve the problem that the safety data in the process of coal mine production are easy to be maliciously tampered with and deleted, a mine consortium blockchain data security monitoring system is proposed. The coal mine consortium blockchain includes supervision department, builds favourable centralized and decentralized production mode, and improves PBFT (Practical Byzantine Fault Tolerance) consensus mechanism to implement practical coal mine safety production. The evaluation shows that the architecture we proposed is more appropriate and efficient for the mine Internet of Things than the traditional blockchain architecture. The Hyperledger Fabric platform is used to build the mine consortium blockchain system to achieve the sensor data reliability, node consensus, safe operation automation management, and major equipment traceability.

矿山联合体区块链：基于区块链的煤矿安全生产应用研究

为解决煤矿生产过程中的安全数据容易被恶意篡改和删除的问题，提出了矿工联盟区块链数据安全监控系统。煤矿联盟区块链包括监管部门，构建有利的中心化和去中心化的生产模式，完善PBFT（实用拜占庭容错）共识机制，实现煤矿安全生产的实际应用。评估表明，我们提出的架构比传统的区块链架构更适用于矿场物联网，效率更高。利用Hyperledger Fabric平台构建矿工联盟区块链系统，实现传感器数据可靠性、节点共识、安全运行自动化管理、重大设备追溯。
