Numerical modelling and microseismic monitoring to improve strata behaviour

Conference Paper


Abstract


  • Numerical models have been developed for an UK based colliery to study the strata behaviour around a longwall face. The modelling indicated that the failure of the roof strata would become more extensive and periodic as the face advances, with vertical shear mechanisms being the dominant form. The failure zones would propagate through the overlying the Sandstones, and well into the strata above, allowing water ingress into the workings. A good correlation has been observed between the numerical results and microseismic monitoring data.
