Based on the Geostress to Research Slope Stability in the Deep Open Pit

Abstract

Further excavation is extraordinary significant to the sustainable development of mine. For the rock slope, three-dimensional geostress in the deep mining area are presented complex and high, which were caused by previous excavation. Also, it is important to obtain the accurate geostress in mining area, which is the necessary precondition for determining the remaining ore mining scheme and the slope stability. In this paper, based on the in-situ geostress monitoring date, a 3D numerical model alongside the physical dimensions was built in finite element software FLAC3D, to accept the constitutive parameter and monitoring data, to predict the 3D stress and displacement distributions and detail failure information, to estimate stability of mining area.
