Analysis of Three-Dimensional Numerical Simulationin on Overlying Strata’s Stress Field and Displacement Field in Thick Seam Mining

Abstract:

It takes the typical coal of mining in S₂S₉ face of Daping mine, using the 3-D numerical simulation to reveal on its face with the vertical characteristics of the stress field and displacement field .The study showed that the overburden strata migration features during the mining process in in thick seam mining of Daping mine.This research can be a reference for safety and high efficient coal mining of other parts of the soft overburden in extra- thick seam mining technology.
