Özet: Drilling-blasting method is generally used in the excavation of industrial raw materials produced by open-pit mining method. Since tons of materials are loosened and crushed at the same time by blasting effect, drilling-blasting applications are considered as more economic production in open-pit mines. However, in the excavation of low-strength rocks, the mechanical excavation is able to be used as an alternative production method. Decreasing in the strength of rock formation to be excavated not only allows for easier excavation but also increase excavation performance. In addition, many operations following rock excavation such as loading and transportation can be carried out more economically in the mechanical excavation method. In this study, the usability of the mechanical excavation method instead of drilling-blasting method was investigated in the gypsum quarry of ABS firm in Ulukışla county of Niğde province. The cost of the drilling-blasting method was calculated for 5 different blasting operations, and the unit cost for each operation was determined. Unit cost values for the mechanical excavation method were also calculated theoretically. By taking into account for obtained results, these two excavation methods were compared in terms of their cost.
