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

Environmental Hazards of Limestone Mining Sciencing

In humid climates, limestone dissolves quickly and is carried away by water. This creates caves which can become weak and collapse. Underground mining of limestone can cause a cascading environmental impact. Mining in the karst can lower the water table, which removes the support of rock that overlies water-filled caverns, which can create
