Design of weak rock slope at BLI open pit lignite mine in Turkey

In this study, critical considerations and the results of a slope stability analysis of Sagirlar Sector (SA-5 panel) of Orhaneli open pit lignite mine, which belongs to Bursa Lignite Establishment of the Turkish Coal Enterprises (TKI) are presented. The stability analyses were carried out in four different directions of the proposed pit both to decrease the stripping amount and to protect the probable damage to the adjesent Altıntaş village. Numerical modeling with 2D limit equilibrium analysis was employed to find maximum safe slope angles in different parts of the SA-5 panel. In numerical analysis, both circular failure and non-circular failure options were considered. The southern and southwestern slopes which bounded by the basin border and contact zone of the seam were appear to be critical in the region. Thus a failure with a composite surface may occur and southern slopes may be safe with a safety berm and overall slope angle of 22 degree. The southwestern slopes of the panel adjacent to the Altintas Village should be safe with an overall slope angle of 24 degree and and should be extended to the fault. The northern slopes were appear to be less critical than the southern slopes. However, the heights of them were much more than those in the southern part.


Assessment of rock slope stability along the proposed Ankara-Pozanti autoroad in Turkey
Avci, Km; Akgün, Haluk; Doyuran, Vedat (1999-01-01)
The main objective of this study is the determination of the slope stability and excavatability category of discontinuous rock exposed between 53 + 000 and 58 + 000 km of the proposed Ankara-Pozanti autoroad in Turkey to provide secure access. The-study area is mostly in the outcrops of highly jointed sandstone with minor layers of marl. This Maastrichtian-Eocene Group also contains conglomerate and limestone bands of flysch character called the Pasadag Group. Quaternary alluvial deposits occur throughout t...
Stability analyses of the dump site culvert in Tınaz surface mine
Özcan, Ömer Can; Ünal, Erdal; Department of Mining Engineering (2003)
In this thesis, studies associated with the stability analyses of the box-shaped dump-site culvert constructed in Tınaz Surface Mine of Turkish Coal Enterprises (TKİ) are presented. In addition, stability conditions of other culvert alternatives are evaluated. Existence of creeks in a surface mining area is a significant factor to be considered in selection of dump-site location. Since, the dumped overburden material on the valley acts as a barrier and behaves like a dam causing flood problem behind the dum...
Numerical simulation of the Çınarcık dam failure on the Orhaneli River
Bağ, Fırat; Bozkuş, Zafer; Department of Civil Engineering (2005)
This thesis analyzes the probable outcome of the fictitious failure of a dam under a set of pre-defined scenarios, within the framework of a case study, the case subject being the Cinarcik Dam located within Bursa Province of Turkey. The failure of the dam is not analyzed neither structural nor hydraulic-wise but is assumed to be triggered when certain critical criteria are exceeded. Hence, the analyses focus on the aftermath of the failure and strive to anticipate the level of inundation downstream of the ...
Europeanisation of the Turkish energy sector
Ünal, Serhan; Tanrısever, Oktay Fırat; Department of International Relations (2013)
This thesis analyses Europeanisation process of the Turkish energy sector by comparing and contrasting the current situation of the sector with the European standards and by using the Turkish electricity market as a case study. In order to do this, it first focuses on the meaning of Europeanisation in energy sector and reveals the fundamentals of it by moving from several European energy strategy documents and 15 Turkey progress reports. The three pillars of Europeanisation in the energy sector are identifi...
Two and three dimensional analysis of a slope failure in a lignite mine
Tutluoğlu, Levend; Karpuz, Celal (2011-02-01)
With about 9.3 billion tons of reserve, lignite is a major source for energy production in Turkey. The Afsin-Elbistan lignite basin, containing 47% of the overall lignite reserve in Turkey, lies in the Afsin and Elbistan districts as a part of Kahramanmaras. The new Collolar opencast mine is in the Afsin-Elbistan lignite basin, and this mine will be the second mining activity in the basin after the active Kislakoy opencast mine. The new mine will meet the coal consumption of the Elbistan B power plant. Inpu...
