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.
