How has mining changed since the middle 1800?

Since the mid-1800s, mining has evolved significantly due to advancements in technology, regulation, and environmental awareness. Mechanization and automation have replaced much of the manual labor, increasing efficiency and safety in operations. Additionally, modern mining practices emphasize sustainability, with stricter regulations to minimize environmental impact and promote responsible resource extraction. These changes reflect a shift from the labor-intensive, often hazardous methods of the past to more sophisticated and regulated approaches.
