A pick force calculation method suggested for tool lacing of mechanical excavators employing drag tools
(Taylor & Francis Ltd, 2018)
This paper deals with tool lacing design of partial-face cutting machines employed for mechanical excavations of rocks, coal and stones. A rational comparison between relief cutting and groove deepening was made by simulating ...
Performance Prediction of Circular Diamond Saws by Artificial Neural Networks and Regression Method Based on Surface Hardness Values of Mugla Marbles, Turkey
(Pleiades Publishing Inc, 2019)
Sawing of natural stones with diamond-impregnated circular saws is extensively implemented in stone processing plants in variety of applications that include sawing, cutting, splitting and trimming. Hence, the cost of ...
An investigation on single-particle impact breakage functions of a gold ore by drop-weight technique
(General Directorate of Mineral Research and Exploration (MTA), 2017)
Impact breakage functions for a gold ore from Bergama region (Turkey) was estimated based on the single-particle impact breakage distributions of particles obtained from drop weight tests. For this purpose, a modified ...
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 ...
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 ...
