The abrasive and rock properties have a significant impact on the performance and profitability of abrasive water jet (AWJ) cutting. In the relevant literature, there is no comprehensive study that investigates the effects of abrasive type on the AWJ cutting of rocks. As a result, in the current study, various abrasives (garnet, white fused alumina...
Abrasive waterjet (AWJ) has been widely used for the cutting of hard materials such as rocks. The AWJ cutting of rocks has been well documented in the relevant literature. In these studies, one-pass cutting is employed as the cutting mode. There is no study focusing on the two-pass AWJ cutting of rocks. Therefore, this study aims to fill this gap....

Doğaltaş sektöründeki üretim ve işleme faaliyetleri sonucunda kayda değer miktarlarda atık
oluşturulmaktadır. Bu atıklar, çeşitli çevresel problemlere (topografya değişikliği, yüzey/yeraltı
sularında bozulma, hava/görüntü kirliliği vb.) yol açmaktadırlar. Bu çalışmada, granit atıklarının (iri ve
ince boyutlu) aşındırıcılı sujeti ile (ASJ) doğaltaş...
Abrasives play a critical role in the erosion process of abrasive waterjet (AWJ). Therefore, they can significantly affect the performance and profitability of cutting. In the relevant literature, there is no comprehensive study investigating the effect of abrasive type on the rock cutting performance. The current study aims to fill this gap. Vario...

Bu çalışmada, Aşındırıcılı Su Jeti (ASJ) ile mermer kesmede farklı tip (garnet, zımpara tozu, cam küre) aşındırıcıların kesme performansları irdelenmiştir. Aşındırıcıların kesme performanslarının değerlendirilmesinde kesme derinliği referans alınmıştır. Kesme deneyleri süresince, kesme parametreleri sabit tutulmuş ve mermer örnekleri uzunlukları bo...
Aşındırıcı sujeti (ASJ) teknolojisi; çok yönlü kesim yapabilmesi, düşük kesme gücü gerektirmesi, malzeme kaybının düşük olması ve termal bozunma oluşturmaması gibi önemli üstünlükleri nedeniyle sert ve dayanıklı malzemelerin kesilmesinde/işlenilmesinde tercih edilen bir teknolojidir. ASJ teknolojisinin çeşitli sektörlerde tercih edilebilir olması,...
Dünya enerji talebi başlıca fosil enerji kaynakları tarafından karşılanmaktadır. Fosil yakıtların üretimi ve tüketimi süreçlerinde açığa çıkan çeşitli atıklar toprak ve su kirliliğine neden olmaktadır. Bunun yanında, fosil yakıtların yanma ürünü olarak atmosfere salınan sera gazları da küresel ısınmaya katkıda bulunmaktadır. Bu çalışmada, fosil yak...
Metan, kömürde oluşan en etkili gazlardan bir tanesidir. Bu gaz, kömür matrislerinde yüzeye adsorbe halde bulunabildiği gibi kömür ve çevreleyen kayaçlardaki boşluklarda serbest veya çözülmüş halde de bulunabilir. Kömür veya yan kayaçlarda bulunan metan, madencilik işlemleri sonucu oluşan kırıklar/çatlaklar aracılığı ile açığa çıkar. Uygun koşulard...
Kömür damarlarında bulunan metan, kömür üreten birçok ülkede madenler ve madenciler için tehlikeli olabilen bir gazdır. Tehlikeli olmasına rağmen kömür kökenli metan (KKM), doğal gazın başlıca bileşeni olması nedeniyle geleneksel olmayan bir enerji kaynağıdır. Hava kirliliği açısından değerlendirildiğinde KKM'nın üretimi temiz bir enerji kaynağı su...
Solid-cutting waste of granite is generated with considerable amounts during the machining processes. Utilization of this waste as an alternative material in various sectors such as construction and building would protect the environment and create a valuable source for the sectors. In this paper, an experimental study is carried out for the utiliz...
As an alternative abrasive, utilization of Brown Fused Alumina (BFA) in abrasive waterjet (AWJ) cutting of marble is investigated in this study. The performance of the BFA is compared with the garnet which is widely used as an abrasive in the AWJ cutting applications. Marble samples are cut with the constant operating variables of the AWJ (traverse...
As an alternative abrasive, use of White Fused Alumina (WFA) in abrasive waterjet (AWJ) cutting of marble is investigated in this study. The performance of the WFA is compared with the garnet which is widely used as an abrasive in the AWJ cutting applications. Marble samples are cut with the constant operating variables of the AWJ (traverse speed,...
Bu çalışmada, Aşındırıcılı Su Jeti (ASJ) ile mermer kesmede aşındırıcı olarak silisyum karbür’ün (SiC) kullanılabilirliği araştırılmıştır. İlgili aşındırıcının kesme performansı, ASJ kesme uygulamalarında yaygın olarak kullanılan garnet ile karşılaştırılmıştır. Kesimler süresince, kesme parametreleri (kesme hızı, pompa basıncı, aşındırıcı besleme m...
Mining is reported as the most dangerous sector in many references. This is due to characteristic difficulties of mining and majority of the uncertainties despite the preliminary studies. Also, a continuous production result in a continuous change in the pit’s working conditions. In general terms, approximately 10% of the all occupational accidents...
Kömür madenciliğinde, birçok maden çalışanı metan ve beraberindeki tehlikeler sebebiyle yaşamını yitirmektedir. Trajik can kayıplarının yanı sıra, gerekli tedbirleri almayan bazı kömür işletmeleri bazı ekonomik sorunlarla da karşı karşıya kalmaktadırlar. Günümüz teknolojisiyle, metan kaynaklı risklerin ortadan kaldırılması/azaltılabilmesi ve çalışm...
History of mining is as old as human history. Therefore, mining has never lost its significance for human
race. Following the industrial revolution, demand for raw materials has been increased dramatically.
Increase in the demand has led the production rate in mining sector boost strikingly which is the only
resource of raw materials. The increase...
In this study, rock cutting performance of abrasive waterjet (AWJ) was investigated and modeled using artificial neural networks (ANNs). A pre-dimensioned granitic rock was sampled and subjected to cut by an AWJ. Cut depth (CD) was assessed as the cutting performance of the AWJ. Three operating variables including traverse speed, abrasive mass flow...
Coal is by far the most plentiful energy resource in Turkey. Domestically produced coal accounts for more than half of the country's total energy production. Coal has been consumed primarily for power generation, steel manufacturing, and cement production. Due to its importance in country's energy balance, modeling and forecasting of coal consumpti...
In this study, Turkey's primary energy consumption (PEC) is modeled by linear regression analysis (LRA) based on population (P). The derived models are validated through some statistical approaches such as the determination coefficient, t-test, F-test, and residual analysis. For the performance assessment of the proposed model, three performance me...
In this paper, regression analysis (RA) was applied for modeling the CO2 emissions of Turkey. Real gross domestic product (GDP), total and urban populations and energy consumption were considered as economic and demographic variables. The developed model was tested using a test data set which were not utilized during building of the model. Addition...
In the current modeling, trend analysis is used to model coal consumption (CC) and forecast the future coal demand in Turkey. The data is divided into two groups as the data for training the model (during the period 1970-2005) and the data for testing the model (during the period 2006-2013). The developed models are tested by the t-distribution, F-...
Kömür kökenli metan (KKM), kömür damarlarında doğal olarak oluşan ve az miktarlarda hidrokarbon ya da hidrokarbon olmayan gazları içeren bir gazdır. Kömürleşme ile oluşmaya başlayan bu gaz, kömür işletmeleri için büyük tehlike oluşturmaktadır. Son yıllarda yapılan araştırmalar ve geliştirilen yeni üretim teknikleri sayesinde kömür işletmeleri için...
