会东矿西边坡岩石力学试验研究

为了评价露天西边坡的稳定性,进行了大量的室内与现场岩石力学试验,主要有岩体和岩体结构面的抗剪强度、岩体弹性模数、岩体应力与应变等试验。综合分析试验结果表明,黑色破碎岩体和软弱结构面是决定西边坡稳定性的主要因素;而处于黑色破碎岩体中的硅质白云岩相对来说完整性较好,它对围岩及边坡稳定性能起一定的控制作用。

EXPERIMENTAL STUDY ON ROCK MECHANICS IN WEST-SLOPE OF THE HUIDONG SURFACE MINE

In order to appraise the west-slope stability at the Huidong Surface Mine, a considerable number of rock mechanics experiments both in laboratory and situ have been taken.The experiments include those on shear strength of rockmass and rock structure planes, rockmass elastic modulus, rockmass stress and strain, etc.The results from the tests and the comprehensive analyses indicate that the black fracture rockmass and weak structure planes are the main influence factors on the westslope stability at the mine, however, the siliceous dolomite zone in the black fracture rockmass has relatively better integrity and can play a certain control function for stability of the wallrocks and slope.
