The integrity loss of physicomechanical properties of building stones when subjected to recurrent cycles of freeze-thaw (F-T) process
(Springer, 2006)
In this study, a total of nearly 900 samples were obtained from 7 different rock types, also recognised as marbles of sedimentary and metamorphic origin and commercially used in the building of various monuments, art works ...
Authors' Reply to Discussion by R. Goktan on "ISRM Suggested Method for determining the Shore Hardness value for rocks" by R. Altindag, A. Guney, International Journal of Rock Mechanics and Mining Sciences, 2006; 43 : 19-22
(Pergamon-Elsevier Science Ltd, 2006)
The authors appreciate the Discussion comments by Dr. Göktan and his interest in the new ISRM Suggested Method. As is known, the Shore Hardness (SH), as one of the physical properties of rocks, is widely employed to describe ...
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 ...
Coagulation/flocculation process for marble processing plant effluent: Modelling and optimization through response surface methodology
(Wiley, 2019)
In this study, the coagulation-flocculation of a wastewater discharged from a marble processing plant was statistically analyzed and optimized. To make a systematic investigation on the coagulation-flocculation of the ...
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 ...
Chemical injection to prevent building damage induced by ground water drainage from shallow tunnels
(Pergamon-Elsevier Science Ltd, 2009)
Progressive developments in the application of chemical injection have been acquired through out the centuries, starting from the ancient Romans. The method of silica based injection has been employed for a long time and ...
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 ...
SEDİMANTER ZAYIF KAYA KÜTLESINDE REÇİNELİ HALAT SAPLAMALARIN UYGULAMA PARAMETRELERİNİN ÇEKME DAYANIMINA ETKİSİ
(Baski, 2019)
Cable bolts which are efficiently used in mining operations, have become widespread in local underground coal mines. Presentation of information about the cable bolt performance in sedimentary units encountered in local ...
Rejection of iron coloring impurities of quartz ore by sulfuric acid bleaching
(Baski, 2019)
Quartz purification by bleaching methods has taken great interest for several decades both for conventional and high technology applications like production of optical fibers, construction of silicon cells and semiconductors, ...
