| Abstract: | Shizhuyuan ploymetallic ore deposit was mining by open stope method for more 10 years. It has left about 2 millions mined-outareas with 8000 m2 of the maximum continued exposed face of roof, and some pillars were slabbing. For some reasons, the mined-outareas could not fill. So based on the mining status, many mining schemes were modeling by the 3D elastoplastic finite element method and the discrete element method. The results of numerical modeling were directed to the determination of mining scheme. |
