摘要

U.S. coal reserves unfortunately exist below gas or petroleum product distribution and transmission pipelines. This scenario is problematic as underground mining of coal reserves results in exposure of the pipeline to ground movement (subsidence) as a result of the mining. Coalfields present across the mainlands of the U.S. are shown in Figure 1. These coal reserves are present from tens to thousands of feet below the ground surface over flat to mountainous terrain.
