Characteristics of Airborne Dust in the Return Airways of the Mechanized Longwall Face
In this paper the results of a research study on the characterisation of airborne dust in the return airway of the mechanized longwall face at Middle Anatolian Lignite Mine, OAL are presented. Dust, temperature, moisture and air velocity measurements were carried out in the return airways of the fully mechanized longwalls. Then the analyses of results on real-time concentration data, mass concentration data, effect of moisture, heat and air velocity on dust concentration are made. It has been found that amount of dust in return airway is directly related to the face activities and to the amount of settled dust on the return airway. Moreover, the relationship between dust deposition rate and distance was studied. Another objective of this study is to determine the reliability of different dust samplers used in sampling. Comparison of results showed that for the lower dust concentration, there is not any significant differences between the measurements of samplers. But as the dust concentration exceeds 15 mg/m3, the difference in measurements becomes significant

Uncertainty Assessment of Well Placement Optimization
Determining the best location for new wells is a complex problem that depends on reservoir and fluid properties, well and surface equipment specifications, and economic criteria. Numerical simulation is often the most appropriate tool to evaluate the feasibility of well configurations. However, since the data used to establish numerical models have uncertainty, so do the model forecasts. The uncertainties in the model reflect themselves in uncertainties of the outcomes of well configuration decisions
Systematical and Radical Precautions in the Prevention of Mine Accidents and Professional Diseases
The increasing demand for energy raw materials and various industrial minerals increased the importance of mining. It is obvious that this demand will be rising in the near future. Mining, due to the risks it involves, requires specific knowledge, experience and continuous technical inspection
