About: Principles of Room & Pillar Mining

Holy shit is minning cool.
Nice video sir.
All our equipment was from Joy .
Great product
sir ,helpful for mining student and miners also....
It's going to take a helluva machine and technology to compete with Joy, The industry standard!
Not surprisingly,coal miners still have to fight daily for a safe workplace. To hear how miners who make safety complaints today are treated by non-union coal operators, check out Raymond Crooke's song "Big Coal Don't Like This Man At All" on YouTube. It tells the true story of Kentucky coal miner Charles Scott Howard, who stood up for safety at an underground mine operated by Arch Coal and was fired as a result. He filed a whistleblower case, won his job back and is working in the mines again!
Nice equipment jus wonder if it will compare to joy
