How Mining Has Evolved Over the Years Rackers

Mining has changed drastically and somewhat remained the same over the years, due to ever-changing technology. Mining was pretty much the same from its inception, through the 1980s. A large majority of the work was done by manual excavation, which means that men used hand-held equipment and pressurized air and water to extract coal.
