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...
A Quantitative risk assessment methodology for occupational accidents in underground coal mines: a case of Turkish hard coal enterprises
Erdoğan, Hasan Hüseyin; Düzgün, H. Şebnem; Kestel, Sevtap Ayşe; Department of Mining Engineering (2016)
Underground coal mining is one of the most dangerous occupations throughout the world. The incidence of injuries and the days lost due to accidents in underground coal mines are much greater than industrial average. In general, the reasons behind an underground occupational accident are too complex to analyze. The risk analysis and assessment is the most suitable method to cope with these type of issues. This study proposes a quantitative methodology for the analysis and assessment of risks associated with ...
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 ...

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...
