High and Steep Slope Stability Analysis Induced by Goaf Based on 3D Fast Lagrangian Analysis of Continua
Contraposing a lead-zinc ore in yunnan province, Adopting FLAC3D which is a three-dimensional finite differential method to analyse the slope stability induced by goaf, The results indicated:the movement of surrounding rock had been being more intense, meanwhile the slope was instability,It might cause collapse and land slide of slope rock if no using filling method to treat timely.The sizeof plastic zone in slope rock reduced greatly after filling the goaf, that greatly improved slope stability. Results of simulation were in line with practical producing, validating that FLAC3D was an effective way of slope stability analysis induced by goaf.
