Investigation of design parameters of a failed soil slope by back analysis
(Pergamon-Elsevier Science Ltd, 2017)
A soil slope instability occurred at the surface facility area of a mine site, which was successfully managed from occupational health and safety point of view, and no human or material loss was encountered. Three different ...
Determination of deformation modulus in a weak rock mass by using menard pressuremeter
(Pergamon-Elsevier Science Ltd, 2018)
The deformation modulus of heavily jointed andesitic rock mass was investigated by using 41 Menard pressuremeter test results and geotechnical information obtained from seven geotechnical boreholes. The geotechnical borehole ...
Prediction of Top Coal Cavability Character of a Deep Coal Mine by Empirical and Numerical Methods
(Pleiades Publishing Inc, 2018)
Longwall top coal caving mining provides high productivity where thick coal seams exist. The study aims to predict the cavability character of the top coal for deep and thick coal seam in Soma lignite basin located at ...
ASIRI BASKILI SINIFTA BIR KAYA KÜTLESINDE AÇILAN DERIN YERALTI AÇIKLIKLARINDA TAHKIMAT SISTEMLERININ DAVRANISI
(Baski, 2019)
Large-scale and persistent deformations can be observed when the ratio of the stresses around the underground opening to the strength of the rock mass is unfavourably disturbed. Such ground behaviour is called squeezing ...
SOMA KÖMÜR HAVZASINDA BIR YERALTI İŞLETMESİNDE ALT TABAN YOLU DESTEK SİSTEMİNİN İYİLEŞTİRİLMESİ
(Baski, 2019)
Maingate and tailgate entries bearing paramount importance for the underground coal mines where the longwall method is employed, cause many down-times when they are exposed to excessive deformation. In order to reduce the ...
Regression Analysis and Neural Network Fitting of Rock Mass Classification Systems
(2018)
Commonly used rock mass classification systems, Rock Mass Rating (RMR), Q-System, and Geological Strength Index (GSI) were used as input for simple regression and Neural-Network fitting. The relationship between the ...
Assessing Rock Mass Permeability Using Discontinuity Properties
(Elsevier Science Bv, 2017)
Field measurement of rock mass permeability is essential that numerous factors influence its directional magnitude. Lugeon test is a popularly conducted field instrument in order to measure hydraulic conductivity of a rock ...
AŞIRI DEFORMASYONA MARUZ KALAN GALERİDE ÇOK KATMANLI TAHKİMAT SİSTEMİNİN UYGULANMASI
(Baski, 2019)
Underground mine openings are driven by installation of light supports as possible as engineering norms dictate. It is possible to ensure adequate advance rates and cost by employing such light support systems. If the ...
