This paper investigates impacts of rock mass properties on dragline performance. Performances of two draglines operated in different rock formations in Tuncbilek Coal mines were analyzed using modified geological strengths index (GSI). Results showed that draglines' performance change with the rock mass properties. Based on the available data, an empirical relationship was generated to estimate dragline production capacity. The estimated excavation amount by the proposed model was found to be consistent with the excavation amount obtained from the field data.

Effect of fly ash on swell pressure of an expansive soil Çokça, Erdal (1999-12-01) This paper discusses the effect of Fly ash on the engineering properties of expansive soils. As reviewed in literature, many previous investigations have shown promising results for improvement of expansive soil after stabilization with Fly ash. Laboratory tests have been conducted on expansive soils obtained from three different regions in Khartoum state. Various percentages of Fly ash such as 0%, 10%, 20%, 25%, and 30% by weight of soil were added to the three soils and their inf...
Analysis of the influences of rock mass properties on the blasting performance in open cast mines Kaçar, Gökhan; Özgenoğlu, Abdurrahim; Department of Mining Engineering (2002) This study has aimed to investigate the influences of rock mass properties on the blasting performance in open cast mines. To this end, discontinuity spacings and discontinuity orientations have been measured and full scale blasts with various designs have been observed in open cast mines of Aegean Lignite(ELI) and Bursa Lignite(BLI) Establishments belonging to Turkish Coal Enterprises (TKI). Influences of the above mentioned rock mass properties on fragmentation and blasting cost have been investigated. Fr...
Effects of stopper rod movement on mold fluid flow at Arcelormittal Dofasco's No. 1 Continuous Caster Lui, Rui; Sengupta, Joydeep; Crosbie, Donald; Yavuz, Mehmet Metin; Thomas, Brian (null; 2011-05-05) Effects of stopper rod movement on transient flow phenomena in the mold and formation of sliver defects are investigated via plant measurements and numerical simulations. First, sliver locations are correlated with stopper rod position and level fluctuation histories in the mold by analyzing images of slivers and process data recorded at ArcelorMittal Dofasco's No.1 Continuous Caster. Then, 3D transient CFD models are developed, validated with plant measurements, and applied to simulate transient flow, part...
Effect of particle size and heating rate on the combustion of Silopi asphaltite Altun, Naci Emre; Kök, Mustafa Verşan (2002-05-01) In this study, the effects of particle size and heating rate on the combustion properties of Silopi asphaltite were investigated. Nonisothermal thermogravimetry experiments were carried out at three different size fractions and five different heating rates. The TG/DTG experiments were carried out from ambient to 900 degreesC in air. The data obtained were analyzed for the determination of the combustion characteristics of the sample. Also an Arrhenius type kinetic model complemented with the weighed mean ac...
