Coal is an energy source that is still an option in the industry and is obtained through mining activities. Mining management and planning if not done properly will have an impact on the environment. The purpose of this study is to identify and analyze the potential environmental impacts of the coal production process. Life cycle assessment (LCA) is a method used to analyze the environmental impact caused by the procurement of raw materials, production processes and product usage. LCA consists of four stages, namely goal and scope definition, inventory analysis, impact assessment and life cycle interpretation. The LCA study, in this case, used the scope of cradle to gate problems carried out at the processing coal mining. The study results show that the potential for global warming is the biggest impact with a total value of 923,284,331 kg CO2 eq followed by 6,935,573 kg SO2 eq and eutrophication of 1,615,406 kg PO4 eq in the second and third positions, respectively. The potential for reducing emissions can be done by developing technology by replacing fuel sources and using effective coal extraction equipment.
