The technology involved in coal mining around the world has advanced a great deal over the years, especially in terms of improving the health and safety of the miners. At the same time mining efficiency and production rates have also improved. These advancements have been made possible, in part, by the increasing use of high pressure pumping systems that power the critical roof support systems and allow the vast array of very expensive equipment to be recovered once a mine has been exhausted.
