Issue Date: | 2002 | Source: | 岩石力学与工程学报 (Chinese journal of rock mechanics and engineering), Aug. 2002, v. 21, no. 8, p. 1130-1135 | Abstract: | 用离散单元法对金山店矿山进行了二维模拟研究,得到了其围岩变形规律,且计算结果为圈定地表的移动和陷落范围提供了可靠的依据;同时,对离散元方法的应用,特别是参数选取进行了有益的探讨。 By using discrete element method,the simulation on an underground excavation iron mine is carried out and the displacement characteristic of the surrounding rockmass is obtained. Meanwhile a new way to determine the contacting parameters for discrete element analysis is presented. |
