Abstract |
Numerical analyses is using Phase 2.8 program performed study the effects of overburden properties and opening depth on the subsidence configurations under sub-critical condition. The computer simulation results indicate that the maximum subsidence decrease with increasing roof thickness. The maximum subsidence is constant if the roof thickness-to-opening width ratio are more than 0.4. The trough width decreases with increasing elastic moduli of overburden and decreasing opening depths. Keywords - Surface Subsidence, Trough, finite element, overburden stratum | |||||||||
