The mechanical properties of rock mass are dependent on the presence of the discontinuities network. Discontinuities of the nature rock mass play decisive role on the design process and efficiency of dimension stone quarries. A methodology has been developed in this paper to optimize the layout of mining process based on the orientation of the measured fracture sets existed in rock mass. For the development of an integrated computer-aided design and planning methodology for characterization of the dimension of quarries, a decision support system has developed based on a numerical modelling and mine planning software. This paper could help to recover the most stone blocks with the sizes and shape adapted to the market demands for marble quarries.
