Question:
Suppose rock bolt load is 16,400 pounds and bolts are spaced on 5 ft centers in a square pattern. Find the bolting “pressure” pb. What layer thickness is this bolting pressure equivalent to assuming a single layer roof beam sagging under self-weight alone with simply supported ends. Note: Specific weight of the roof layer is approximately 158pcf.
