Land use land cover change analysis of Afşin Elbistan coal basin with two different classification methods

Arıcan, İlke
Surface coal mining is one of the most widespread energy and economic source for the communities and if implemented inappropriately, causes negative short and long term environmental, social and economic effects (such as loss of vegetation, migration, decreasing water resources, etc.). In order to detect, minimize and avoid all of these impacts, affected areas should be monitored and mapped, constantly. Monitoring surface mining activities by using land use land cover (LULC) maps is one of the effective methods for large areas. However, finding the suitable method for constructing LULC maps for monitoring has been a challenge. Remote Sensing (RS) and Geographical Information Systems (GIS) have been helpful for generation of LULC maps. In this study, two change detection methods, namely, the post-classification change detection based on Support Vector Machine (SVM) and Change-Detection-Driven Transfer Learning Approach (CDTL) are used to monitor change detection in LULC classes in the Afşin-Elbistan Coal Basin, which is one of the largest surface coal mines in Turkey. The Landsat imageries of Afşin-Elbistan Coal Basin for the years of between 1984 and 2014 are utilized for the analyses. The progressive change in the LULC classes since the beginning of the mining activities are obtained quantitavely. The LULC change detection maps reveal that the vegetation class increases by 3.2%, forest class increases by 55.9%, agriculture class decreases by 5.9%, settlement class decreases by 96.2%, water class increases by 608.1% and soil class decreases by 8.1% between the years 1984 and 2014. It is found that the most and the least effected classes are water and vegetation, respectively. The comparison of post classification change detection based on SVM and CDTL shows that difference in the results are not significantly high. Nevertheless, post classification change detection based on SVM results in higher accuracies than CDTL for each year.


A Sustainability assessment framework for evaluation of coal mining sector plans in afşin-elbistan coal basin with a special emphasis on land disturbance
Yaylacı, Evren Deniz; Düzgün, H. Şebnem; Department of Mining Engineering (2015)
The mining sector has negative and positive impacts on the environment, society and economy at the local and national levels. Mitigating and minimizing the negative impacts while maximizing the social and economic benefits of the mining sector are significantly important for contributing to sustainable development in practice. For this purpose, different assessment tools, which can be applied at different decision-making levels, are used in the mining sector and sustainability assessment (SA) is one of thes...
Soil contamination mapping for an abandoned coal mine site by using worldview 2 and aster imagery
Soydan, Hilal; Düzgün, H. Şebnem; Department of Mining Engineering (2013)
Being an indispensable economic and energy source, coal mining may be the cause of long term environmental damages like serious water and soil contamination due to inappropriate mining operations. In order to detect and avoid it, mapping the contamination levels related to mining industry has been a challenge for soil scientists to find the most appropriate and time and cost effective method for constructing soil contamination maps. So far, Remote Sensing (RS) and Geographical Information Systems (GIS) have...
A preliminary study on the use of reservoir simulation and coal mine ventilation methane measurements in determining coal reservoir properties
Erdoğan, Sinem Setenay; Okandan, Ender; Kracan, Cevat Özgen; Department of Petroleum and Natural Gas Engineering (2011)
This thesis investigates methane emissions and methane production potentials from abandoned longwall panels produced or emitted due to mining activities either from coal seam or any underlying or overlying formations. These emissions can increase greenhouse gas concentrations and also pose a danger to the underground working environment and to miners. In addition to the safety issues, recovery and utilization of this gas is an additional source of energy. In this study, methane concentrations measured from ...
Land use / land cover change detection and the impacts of territorial development plans on the change in muğla

Forests play a vital role in balancing atmospheric carbon dioxide and thereby diminish the pace of global climate change. Agriculture fights against extreme poverty and feeds a projected 9.7 billion people world population by 2050. Although these natural and agricultural lands are so important for now and the future, they have been shrinking all around the world, especially in developing countries. As in some other developing countries, many metropolitan cities face Land Use (LU)/Land Cover (LC) change in T...
Analysis and modelling for risk management for underground coal mines’ safety
Eratak, Özlem Deniz; Karpuz, Celal; Department of Mining Engineering (2014)
Safety in underground coal mining has become an important issue because of increasing number of accidents. There are many different hazards may cause these accidents and the most efficient method for coping with risks is the use of risk management techniques. In this thesis, accident data including workday losses, age of the injured, organ affected by accident, season, shift and reason of the accident was collected from TKI mines (ELI- Soma Eynez and GLI Tuncbilek) and TTK mines. Those variables were initia...
