In order to solve the problems of poor sharing, weak transparency, and poor management of coal machinery equipment information resources, a whole life cycle information resource management method for coal machinery equipment incorporating the Internet of things and block-chain technology was proposed. Firstly, the key technologies of data acquisition, remote transmission and data processing in the environment of internet of things are studied to realize the information acquisition, transmission and storage of coal machinery equipment. Then, based on the decentralized, traceable and non tamperable characteristics of block-chain technology and the existing step-by-step intelligent production network in the research and development, production and use of coal machinery equipment, a block-chain model for the whole life cycle of coal machinery equipment is established, and the data of each link is equally connected according to the smart contract paradigm on the chain, so as to realize the data connection and sharing of the whole industrial chain and the complementary innovation technology of the industrial chain. Finally, the coupling model of the Internet of things and block-chain is established, and the challenges in the application of the coupling model in the coal machinery equipment's whole life cycle information resource management are analyzed and summarized. This study can strengthen the supervision of coal mining enterprises, realize the large-scale sharing of coal machine design and manufacturing resources, and protect the information security of data.
