Abstract: As a pillar industry of the national economy, the coal sector has long been challenged by high energy consumption and inefficient extensive development models. Under the "Dual Carbon" strategy, there is an urgent need to achieve green transformation through systematic management tools. This study employs the Total Energy Management (TEM) theory as a framework, combined with practical exploration at the Shandong Sanhekou company, to systematically demonstrate the implementation strategies of energy lean management in coal mining enterprises. By integrating lean management principles with energy flow analysis methods, the research constructs a collaborative optimization model encompassing strategic planning, process control, and digital empowerment, focusing on addressing issues such as energy waste in production processes, equipment inefficiency, and fragmented management. Case studies reveal that TEM theory significantly enhances energy utilization efficiency, reduces hidden losses, and improves cross-departmental collaboration through full lifecycle equipment management, process synergy optimization, and digital platform development. The study identifies critical bottlenecks in the energy management of the case enterprise, including weakened environmental protection functions, disconnection in policy implementation, and insufficient equipment coordination. Accordingly, a department-specific refinement plan is proposed, clarifying collaborative responsibilities across functional units in material supply, production scheduling, and equipment maintenance. Future research should expand the lifecycle perspective and explore synergies between carbon sequestration technologies and lean management to advance coal mining enterprises from singular emission reduction to systematic carbon neutrality.
