The "Proceedings of the third workshop on surface subsidence due to underground mining" focuses on understanding surface sinking caused by digging underground for coal. In this workshop, experts discussed the impact of coal mining on land in the Northern Appalachian region and Northern West Virginia. They explored how mining practices, particularly in longwall mines, affect the environment. The research shared during the workshop revealed new insights about the ways mining can lead to land sinking, showing the importance of careful planning and monitoring to minimize these effects.
