     since decades rockbolts are widely used as a support measure in mining and civil engineering. a procedure for anchor design based on numerical simulations is proposed for tabas coal mines, which includes the following steps: determination of rock mechanical parameters, transformation of rock mechanical parameters into rock mass parameters by using rock mass classification schemes, set-up of numerical model including the real geological situation, simulation of excavation without anchorage and investigation of model response (determination of stability/instability, deformations, etc.), incorporation of anchors into the modelling and investigation of model response, especially in respect to the reinforcement effect. a detailed evaluation of the model response in form of the displacements, stresses, deformations, plastifications and anchor forces was performed. the developed methodology and software routines are a sound basis for future anchor optimization and safety improvement in tabas coal mines.
