Study on the Law of the Movement and Damage to Slope with the Combination of Underground Mining and Open-Pit Mining

Abstract

Under circumstances in which both underground mining and open-pitmining are employed, the mining effects of two approaches will besuperposed and the mining slope will receive several induced stressfields, which makes the sliding mechanism and deformation law of sloperock, mass more complicated. This paper, targeting at the east slope ofAntaibao Mine with the joint employment of underground mining andopen-pit mining, aims to study the moving law of the slope rock massand the damage mechanism to the overburden of the goaf by numericalsimulation. It is supposed that models of possible damage to the slopecould be explored for guidance to safety-production of the mine.
