Transportation cost is the dominant cost and accounts for almost half of the total mining cost in surface mining. Therefore, determining transportation cost is critically important for the economic feasibility of mining projects. Turkey produces around 85 million tons of lignite per annum. The biggest state-owned company, Turkish Coal Enterprises (TKI), accounts for 43 per cent of the country's total lignite production. Around 85 per cent of the produced lignite is used in power plants for electricity generation and 15 per cent is used for domestic heating in cities and urban areas. On behalf of the Turkish government, TKI distributes around 2 Mt of lignite annually, at no cost to poor needy families countrywide in accordance with Social Assistance and Solidarity Funding aid. Subcontractors are utilized for lignite transportation, and conflicts arise due to the different transportation cost calculations at different mines. A robust model that provides unbiased cost estimations is therefore of paramount importance. This paper presents the transportation cost estimation software, NAKMAL, that has been developed for estimating the transportation cost of lignite from the mine face, including excavation and loading, to various final destination points through five different transportation scenarios. NAKMAL was designed using Visual Studio.NET, validated using field data and some case studies, and it is currently being used by TKI for calculation of transportation cost country-wide.

Developing a coal transportation cost estimation model for Turkish coal enterprises Demir, Ebru; Karpuz, Celal; Department of Mining Engineering (2009) 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 s...
Development of a dynamic maintenance algorithm with multiple scenarios: a case study for surface mining Ölmez Turan, Merv; Gölbaşı, Onur; Department of Mining Engineering (2019) Surface mining operations such as ore extraction and overburden stripping activities highly depend on machine performance. These machines’ operational plan aims to handle required amount of material within a specific period with the lowest maintenance cost and the highest availability. In order to achieve these objectives, the machines should be adapted to the production schedule properly. On this basis, maintenance policies play crucial roles in the sustainability of operations. A maintenance policy is bas...
Microscopic fuel consumption modelling for haulage trucks using discrete-event simulation Kına, Elif; Gölbaşı, Onur; Department of Mining Engineering (2021-2-5) Mining is one of the machine-intensive sectors, and a vast amount of energy is consumed in many stages of mining operations. Among these operations, haulage systems hold a significant share in energy consumption. At this point, diesel fuel, a form of fossil fuel, is frequently used for haul trucks such that fuel-induced cost becomes a major contributor to the operating cost, especially in surface mining. Fuel consumption also leads to greenhouse gas emissions, in addition to its financial burden. Therefore,...
Evaluation of rail freight transportation in Turkey prior to deregulation Cebeci, Alper; Tüydeş Yaman, Hediye; Department of Civil Engineering (2019-3-16) Rail freight is a major component of industrial development in a country, as it provides very cheap transportation opportunities for raw materials, such as coal, ores, etc. However, due to its stop-to-stop nature, it always requires a first- and last-mile connection with another mode, thus, has relatively longer total travel times. As a results, it can hardly earn the revenues necessary for its operations and has been heavily subsized by govermnets in many coun...
Development of a Dust Violation Control Tool from Plant Data Erkayaoğlu, Mustafa (null; 2018-11-22) Mining is an equipment-intensive industry that utilizes machinery both in production and mineral processing. As an essential part of sustainable development, mining is subject to environmental management from many aspects. The decision-making process integrated into all stages of mining has to be based on reliable data. Available technology enables to track and monitor the production stages in mining by using various sensors and systems. Data related to mining and mineral processing activities have differen...
