EBolt is made of smooth round bar with paddle configuration. It is an effective rock reinforcement system for underground roof support. If there is rock mass deformation, the paddle part will be worked as anchor points to bear the load and smooth section will absorb energy to prevent rock fall.
Rock bolts are big business. A medium size Swedish mine could consume 100,000 bolts per year and the global market could be as high as 100,000,000 per year. They are mounted using powerful rock drills that also inject the high pressure concrete. Rock bolts are "mission critical". If one or several bolts in a tunnel fail, a cavein could be ...
This type of mining is best suited for tabular narrow vein orebodies, with enough dip to allow for gravityled ore flow. Experience has shown that raises from 75 to 150 metres length are the most economical. Results are even more favourable when the ore boundaries can be interpolated between adjacent raises, allowing drill design to be adjusted as required. Raise Climber Mining Method Details ...
