- W2349231734 abstract "Using simulation software Midas/GTS,a numerical simulation model is set up.The simulation of take every other one recovery process of an underground metal mine is carried out.At first,the condition of stress,displacement,plastic zone of the 56-7# pillar are revealed when the 56-6# stope is mined;and then,the changes of stress,displacement,plastic zone of the 56-7# pillar and surrounding rock are revealed in pace with the 56-8# stope mining step by step.Also,the possible destructive positions of pillar and surrounding rock during mining are analyzed and forecasted.Using 3D laser detection(CMS) technology and 3D modeling technique,3D shape of goaf and pillar are obtained rapidly and accurately.It verifies visually numerical simulation results of the destructive position of pillar and surrounding rock during mining of take every other one.Practice has proved that the above methods open up a new way for the analysis and prediction of the destructive position of pillar and surrounding rock during mining in similar deep well.It is of an important practical significance for the guiding of the next blast design and the safe and efficient exploitation of mines." @default.
