Research on the Slope Sliding Mechanism of Excavation of Steeply Inclined Mine from Open-Pit to Underground

Abstract:

The stress of slope is in dynamic changes from open-pit to underground of the mining excavation . In this article, based on the relationship of space corresponding through the two mining methods, and two types of mining influence dominated overprint and containing characteristics, it can find out its regularity according to the numerical simulation, and also can reveal the induced with mutual interference between two excavation system mechanism, deformation of foundation and its numerical size out of dangerous area from the mining effect of interaction and mutual superposition characteristics; On this basis, it also analyzes its influence on the stability of the slope characteristics and deformation law, and puts forward to the control methods which provide the decisions basis for the mining safety production.
