Development of a computer-based risk assessment tool for underground coal mines
Başayar Büyükkara, Fatma Nur; Karpuz, Celal; Department of Mining Engineering (2016)
Underground coal mining remains one of the world’s most hazardous occupations. There are numerous hazards in a mine, such as gas, dust, noise, temperature, and high humidity. Besides, increasing number of occupational accidents in underground coal mines shows the importance of occupational health and safety in these workplaces. By means of Occupational Health and Safety Law No 6331, attention to health and safety in the workplace has grown in recent years in Turkey. In addition, conducting an occupational h...
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...
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...
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 ...
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...
