Özet:

Transportation cost is an important item in total operating cost of an open pit mining operations. In some projects, the transportation cost may reach to 60 % of total operating cost. Turkish Coal Enterprises (TKİ) delivers the demanded coal to all cities of Turkey within the context of Prime Ministry Social Solidarity and Aid Fund. The project duration, demanded coal amount whether the coal is needed as packed or unpacked form are determined by local governors. In this study, a model is developed through software, called NAKMAL for the estimation of TKİ’s coal transportation cost. Transportation cost model is coded using Visual Studio.NET 2005. This model is designed in modular structure and composed of 19 modules. Excavation and transportation in a mine is an important part of the model. Model considers all the highway, railway and transportation by ship alternatives, as well as the packing operation. This model is being used in evaluation of bids by the decision of TKİ’s board of executive committee.
