Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Accurate three-dimensional geological and numerical computing model were established by the mining engineering software 3DMINE and finite element analysis code MIDAS/GTS, and the excavation process was simulated completely according to the pre-designed mining sequence of panel stope. The results showed that the stability of stope structure with the size increasing of ore pillar of reconstructed mining environment had some rules as follow: 1) The maximum value of tensile stress and vertical displacement of roof structure decreased gradually, and stress conditions had been improved. 2) Most part of the four size ore pillars´s von mises equivalent stress value was less than the ore-rock uniaxial compressive strength. 3) When the size changed within a certain range, it was not too much significance to reduce the tensile stress area and vertical displacement of roof by increasing its size. Thus, as for ore pillar, from the perspective of mechanics, there is a reasonable size range in which stability of the re-constructed mining environment is in an ideal state.
