A large vertical finished (inside) shaft diameter of 9.75mis required for hoisting capacity in a planned high
Question:
A large vertical finished (inside) shaft diameter of 9.75mis required for hoisting capacity in a planned high volume underground oil shale mine. An aquifer is encountered at a depth of 387 m where the water pressure is 1.66 MPa.
(a) Determine the thickness of a concrete liner needed for a liner safety factor of 2.5 when the concrete compressive strength (Co) is 24.2 MPa, Young’s modulus is 38.62GPa Poisson’s ratio is 0.27. Explain, defend your answer.
(b) If changes in the inside diameter of the shaft are monitored for safety, what “reading” in cm would indicate impending failure of the liner?
