Protection Of Pipelines Affected By Surface Subsidence (ace40ef2-89c0-46f6-93fe-b47ae8d105e7)

Surface subsidence process due to underground coal mining often has the potential to cause problems to buried pipelines. In this paper, a technique for assessing the stress level on a subsidence-affected pipeline is introduced. The main contributors for the stresses on the pipelines are identified. Mitigation techniques for reducing the stress on the pipeline have been proposed and successfully tested.
