An underground storage cavern is solution mined in a thick salt bed where Co = 13,200 psi
Question:
An underground storage cavern is solution mined in a thick salt bed where
Co = 13,200 psi To = 1,230 psi
γ = 144pcf E = 5.0 × 106 psi
G = 2.0 × 106 psi
and depth to the cavern center is 1,450 ft. The cavern has a spherical shape and is 150 ft in diameter. The premining stress is hydrostatic. Estimate the wall safety factor.
