BACKGROUND Majan Mining Company is involved in the quarrying of Limestone in the Uyun Mountain range, west of Teetam, near Salalah in the Dhofar region of Southern Oman. The company produces crushedprocess. The structural aspects of overburden and floor material play a significant role in the predictive behavior of rock masses in response to the mining operations, especially of highwall stability and the formation of spoil dumps (1), and therefore, the choice of mining parameters. These parameters include bench width, height, and slope angle.
