Limestone is surface mined through open pit quarries or hillside cuts or horizontally by tunneling under the overlaying surface rock. Limestone is generally blasted with dynamite in an open pit mines hauled by large trucks to processing machines. There is very little waste that is produced during the extraction of limestone waste would contains carbon monoxide and other pollution from machines exhaust, along with used tires. Drilling and blasting to shatter rocks onto the truck.
