• Description:
  In this study, we tested the ability of ground penetrating radar (GPR) to resolve ground conditions in two underground limestone mines. The objective of our work was to determine if GPR signals could be received from distant fractures in the limestone unit. At site A, located in western Pennsylvania, a large fracture penetrated and crossed the mine workings and created mine roof problems. GPR was used to evaluate the mine roof areas along the projection of the fracture. At site B, located in central Pennsylvania, fracturing of the host limestone provided difficult water problems at the mine face. GPR was used at this site to evaluate the conditions ahead of the mine face to determine if a significant joint-based solution channel system existed that would signal a continuation of the water problems. We conclude that, at both sites, it was possible to use GPR to delineate potentially dangerous ground conditions. [Description provided by NIOSH]
