Underground Mining Discussing the underground mining process, machines used, and unique safety protocols in noisy environments. Moving from installing glass to working in the mines. Amount of physical labor involved in mining. Underground mining process. Running a continuous miner, and the extreme temperatures the operator can face. When wearing extra hearing protection can enhance your awareness. The machines and steps used to move product from underground to surface. Atmospheric pressure change when going 3460 feet underground. How spacious it is underground. Ground control process using dywidags, epoxy, and cross bars. How safety measures have improved. Calming your emotions in emergencies. Tempered Glass Glass heated to 700°C then quickly cooled. Increases strength by 5 times. Glass cannot be cut or altered after the tempering process. Glass Shatters safely into small fragments. Able to withstand temperature shifts up to 250°C. Continuous Miner 180 tonnes, 11'6" high, 18' wide. 2 x 500 to 700hp engines. Advances at 1.5 feet per minute. Product is moved onto load car then to robotic tram. Robotic Tram Automatic machine that follows the continuous miner. Deposits product onto room belt from various directions. 16 sections, 340 feet long. Scoop Tram Used for smoothing out fines, moving material, and scaling. Scaling Removal of loose material from walls and ceiling of mine. Dywidag Steel threaded bar used for stabilizing ground overhead. Held in place with epoxy. Name a combination of Dyckerhoff & Widmann AG Brattice Makes a partition for directing air ventilation.
