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, ...
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 ...
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 ...
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 ...
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) ...
Predicting the relationships between brittleness and mechanical properties (UCS, TS and SH) of rocks
(Academic Journals, 2010)
This paper presents the evaluation of uniaxial compressive strength (UCS) predicted from Shore hardness (SH) tests and to correlate brittleness concepts, which are derived from UCS, tensile strength (TS) and Shore hardness ...
Relations between some quantitative petrographic characteristics and mechanical strength properties of granitic building stones
(Pergamon-Elsevier Science Ltd, 2011)
[No abstract available]
Grinding and classification performance evaluation and modelling of an industrial-scale horizontal roller mill process
(Bauverlag Bv Gmbh, 2016)
Cement is conventionally produced in multi-compartment type ball mills which is a energy intensive process [3]. Typical energy consumption of the grinding stage of cement production is about 40 kWh/t in a cement plant [4, ...
