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.

The news comes barely a day after the miner announced it was scrapping the sale of its Nickel West division.

Alberta, which derives a quarter of its economy from the oil sands and other energy resources, is poised to grow at the slowest pace in five years as crude prices slump.

Mining companies today face a complexity of problems: spiraling costs, government intervention, deepening pits, lower ore grades, lack of community trust, and declining productivity are just some of the issues.

Chinese steel mills restart production but ore demand remains modest.

Sandvik Fire Suppression has announced the launch of Eclipse™, a world-first environmentally friendly fluorine-free fire suppression foam for mobile equipment, and which rapidly biodegrades – unlike conventional foams that can persist in the environment for thousands of years after discharge.

Kyrgyz government moves to revoke Stans Energy's licence for rare earth mine and plant that was the main global source of heavy REEs during the Soviet era.
