Analysis of the self-similarity of single particle impact breakage distributions of cement clinker particles
(TMMOB Maden Muhendisleri Odasi, 2017)This study analysis how the impact breakage pattern changes at different specific comminution energy levels. Impact breakage patterns of two different cement clinker samples were investigated by plotting size-normalized ... -
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 ... -
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 ... -
Coagulation/flocculation process of marble wastewater: A preliminary (quadratic) statistical model
(TMMOB Maden Muhendisleri Odasi, 2017)In the scope of this preliminary work, the turbidity removal of an aqueous marble waste was investigated. The effect of the Fe-coagulation and PEO-flocculation on the supernatant turbidity was statistically modelled. The ... -
Effect of operational conditions on energy efficiencies of air-swept ball mill and classification circuits in cement raw material production
(Baski, 2019)Operational performance and energy efficiencies of cement raw material grinding air-swept ball mill and classification circuits were analysed and discussed in this study. Extensive sampling surveys were performed around ... -
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 ... -
Investigation of chromite preconcentration by comminution
(Baski, 2019)Chromite is the main source of chromium. It is widely used in metallurgical, refractory and chemical engineering applications. Chromite occurs in earth crust generally with serpentine minerals as associated gangue. Serpentine ... -
Performance evaluation of a conventional closed circuit process at different cement productions
(TMMOB Maden Muhendisleri Odasi, 2017)Performance of a conventional Polysius® two-compartment ball mill and a OSepa® high efficiency dynamic air classifier (FLSmidth) closed circuit process was investigated at the steady state conditions at CEM II type Portland ... -
Quartz bleaching by oxalic acid: Relationship between rejection rate of impurities and color response
(Baski, 2019)Quartz beneficiation has been applied to meet market requirements by physical and/or chemical methods. Chemical beneficiation has long been investigated by inorganic (e.g. sulfuric acid) and organic (e.g. oxalic acid) ... -
A rational comparison of groove deepening to relief cutting in terms of tool spacing with drag tools
(TMMOB Maden Muhendisleri Odasi, 2017)This paper mentions a rational comparison between relief cutting and groove deepening for tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. The comparison ... -
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, ... -
