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.
Because of the complex influencing factors, it is very difficulty to resolve the problem of large scale pillar extraction and goaf disposal in underground mine. Fortunately, with the rapid development of computational mechanics, numerical methods and computer technology, the feasibility of numerical simulation has become an important feature of the current rock mass mechanics. Accordingly, using the employment of numerical simulation techniques in the calculation and study on failure of single pillar, and even pillar group is undoubtedly a greatly feasible and effective means. In this paper, mining technical features of pillar group of No.92 orebody in Tongkeng Tin Mine of Huaxi Group was analyzed and stoping sequence in zoning of pillar group was designed. On the basis of modeling by using Surpac software, FLAC3D software was then used for numerical simulation. Combined with simulation results and field condition, the reasonable stoping sequence was determined. Also, the results provide scientific reference basis for the safety production of the mine.
