TİPİK BİR UZUNAYAK MADENİNDE TOPUK GERİLMELERİNİN SAYISAL SİMÜLASYONU

Coal is still the major resource to meet expanding energy demand and widely used in coal-fired thermal power plants taking advantage of rich reserves cost-effective production. Longwall mining a method that Türkiye, line with trend world, enables economical sustainable production underground coal resources mechanized equipment. Estimation stress distribution concentration zones excavation face roof critically important terms determining appropriate hydraulic support properties by longwall mining. Advancing wide along direction causes in-situ rock mass change stresses associated intensify. This may trigger potential instability events. study investigates relationship developed on pillars due pillar dimensions field loadings typical mine using numerical simulations. Parametric analysis was performed three-dimensional models Distinct Element Method. The simulation outputs characterize performance alternative designs under different loading conditions, will develop
