• Environmental Hazards of Limestone Mining | Education

    Limestone mining can affect ground water conditions Limestone deposits often occur in association with karst, a topography where limestone slowly dissolves away underground The deposits result in sinkholes, caves and areas of rock fractures that form underground drainage areas When mining occurs in karst, disruption to natural aquifers, or flows of underground water, can result Often
