Question #2 - Rocko Solid mining company has just acquired underground limestone, underground flourspar, underground coal and surface iron operations as part of their attempt to become a vertically integrated steel supplier. In all of their mining operations the rock strata immediately over-lying the "ore zone", coal seam, or stratagraphic unit being mined is a massive limestone. In all cases the massive limestone is strong, unfractured, and not prone to slabbing or scaling.

Unless the mine manager can show and satisfy the MSHA officials that their roof conditions do not require it, what is the maximum roofbolt pattern spacing that the regulations require for each of Rocko Solid’s mines (provide citation support for your claim)

For the Iron Mine _____ X ______

For the Flourspar Mine ____ X ____
