Summary: With the rapid development of China's economy, the extensive mode of growth supported by coal has caused great damage to resources and the environment. Problems such as gas drainage, coal gangue dumping, water resources destruction, and surface subsidence during the coal mining process have directly led to severe damage to the environment in the mining area to ensure the survival and development of the coal industry, and to achieve sustainable development, we must actively promote the "optimized layout, intensive development, green mining, safe production, and clean use." This paper proposes the multimedia communications model and green low‐carbon development mechanism in coal industry with cloud Internet of Things (IoT) to deal with this challenge. In a distributed computing scenario, the communication bandwidth between different nodes is very limited and heterogeneous, and some different computing nodes support a wide range of computing capabilities. Decentralized computing connects devices with computing power to the network, and the nodes communicate directly or indirectly will deal with this challenge effectively. The multimedia transmission is also applied to guarantee the visualized model. The experiment compared with the other state‐of‐the‐art methodologies has proven that the proposed model has the higher transmission efficiency and robustness. [ABSTRACT FROM AUTHOR]
