Slope Stability of Deep Mining in Open Pit Based on FLAC3D
In order to study the stability of the overall slope of deep mining in open-pit mines with complex geolog-ical conditions,according to the on-site drilling data and geological survey,the complex three-dimensional geolog-ical body model was established by the rhinoceros software,the model was meshed by the griddle software,and the FLAC3D three-dimensional numerical analysis software was imported for calculation,and finally the stress size,dis-placement,plastic zone distribution,shear strain increment and minimum safety factor value of the open-pit slope of the mine were obtained.Through the analysis of the calculation results of the three-dimensional software,the stabil-ity of the deep mining slope of the open-pit mine is obtained,which provides a theoretical basis and technical sup-port for the monitoring and division of key areas of the deep mining slope of the mine and the safety production of the mine.
