Historically, limestone was mined using manual methods such as hand tools and basic machinery for drilling and blasting. As technology advanced, mechanized techniques like continuous miners and drilling rigs became common, allowing for more efficient extraction. Presently, modern technologies such as remotely operated equipment, GPS-guided systems, and automated quarrying machinery are used to enhance safety and productivity while minimizing environmental impact. Additionally, digital technologies like data analytics and drones are increasingly employed for exploration and monitoring.
