Last week’s question and answer to Trivia Quiz #1 was:
The topheading from both the east and the west is being excavated now,  and that work will be followed by the bench, or bottom portion.
Q: Why is the top section of the tunnel being excavated first?
A: By excavating the top section of the tunnel first the miners maintain better control of the surrounding rock, which allows more efficient tunneling.
