  • WORKPLAN GUIDANCE DOCUMENT FOR MINING BELOW

    AT LIMESTONE QUARRIES Currently, mining operators are required to complete a detailed hydrogeological investigation to evaluate the potential for sinkhole development or ground surface subsidence from dewatering when excavating below the water table at limestone quarries. The term “limestone” applies to any carbonate formation where the
