In mining industry, waste storage is a very prominent issue; in this respect, safety of storage structures is one of the leading problems in the industry. Most of the tailings dams require remedial measures, throughout their lifespan to increase their reliability. The objective of the study is to investigate stability problems of formerly constructed but newly raised Eti Copper Mine tailings dam and alternative dam geometries for future raises. Plenty of methods were developed to analyze the reliability of structures; limit equilibrium methods, finite element methods and finite difference methods are among them. In this case, stability of the dam was analyzed with finite element method under static loading conditions. In order to determine input parameters properly, disturbed samples obtained at the field investigations were used. For this purpose, several laboratory experiments were conducted to determine natural moisture content, grain size distribution, specific gravity, Atterberg limits, maximum dry density and shear strength parameters of tailings and embankment material.

Stability investigation of Eti borax mine Hisarcık tailing dam using finite element analysis Mokhtari, Pozhhan; Düzgün, H. Şebnem; Department of Mining Engineering (2014) Today, with modern technological developments, the need for raw materials has also increased, which resulted in the development of mining industry. Therefore, there should be a plan for tailing storage and constructing a reliable tailing dam to store waste materials. In this study, the current and reckoning condition of the height rising in Hisarcik tailing dam is investigated for any potential stability problems. This tailing dam is one of the main tailing impoundments in Emet Borax mine, which is located ...
Risk assessment by fault tree analysis of methane explosions in Turkish hard coal enterprises underground mines Mevsim, Rıdvan; Demirel, Nuray; Department of Mining Engineering (2016) Mining is one of the most hazardous industries in the world. Among all mining professions, underground coal mining has the highest occupational accident and disease rates. Methane explosion appears as the major accident type which results in severe loss of life and property in underground coal mining. Including underground coal mines, preparing a practicable risk assessment is the primary step to sustain a safe workplace environment. The main objective of this study is to specify the root causes of methane ...
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...
Monitoring and statistical modelling of dust concentration of some Turkish lignites under laboratory conditions Karakaş, Ahmet; Güyagüler, Tevfik; Department of Mining Engineering (2010) Although technological developments enable maximum safety, high dust formation is still a crucial problem in coal mining sector. This study is aimed to investigate the relationship between amount of coal dust produced during cutting operation and some important coal properties together with cutting parameters for different particle size ranges in laboratory conditions. For this purpose, six Turkish lignite samples were used in the experiments. Two experiment sets were designed to generate coal dust by using...
Discrete event simulation of a shearer performance for a longwall operation Yılmaz, Enver; Karpuz, Celal; Erkayaoğlu, Mustafa; Department of Mining Engineering (2018) Coal is an essential part of energy generation worldwide and has a major role in sustainable development. The amount of coal that can be extracted by surface mining is getting less which makes efficient underground mining operations crucial for both local and global economy. Underground coal mining is considered as a risky industry with a requirement of high amount of equipment investment. The majority of the investment in underground coal mines is generally related with the capital cost of initial equipmen...
