Rippability Assessment in Surface Coal Mining



Rippability assessment studies at Tuncbilek Coal Mine: A case study
BASARIR, H; Karpuz, Celal; BOZDAG, T (2000-11-09)
This paper presents the results of research on rock rippabilities at Tuncbilek Coal Mine. First, direct ripping runs were carried out at four different panels of Turkish Coal Enterprise's (TKI) Tuncbilek Coal Mine by using Komatsu D155 and Caterpillar D8N type dozers. During direct ripping runs, the length of each run, depth of tyne, the change of ripping depth during run, average width between runs, ripping time, and maneuvering time were all measured and recorded to calculate the hourly production. Then, ...

Shear strength of municipal solid waste for stability analyses
Stark, Timothy D.; Huvaj Sarıhan, Nejan; Li, Guocheng (Springer Science and Business Media LLC, 2009-06-01)
This paper investigates the shear strength of municipal solid waste (MSW) using the back analysis of failed waste slopes as well as field and laboratory test results. Shear strength of MSW is a function of many factors such as waste type, composition, compaction, daily cover, moisture conditions, age, decomposition, overburden pressure, etc. These factors together with non-standardized sampling methods, insufficient sample size to be representative of in situ conditions, and limited shear displacement or ax...

Stress Scaling Factors for Seismic Soil Liquefaction Engineering Problems: A Performance-Based Approach
Çetin, Kemal Önder; Bilge, Habib Tolga (2013-06-19)
Most of the widely used seismic soil liquefaction triggering methods propose cyclic resistance ratio (CRR) values valid at the reference normal effective stress (sigma(v,0)') of one atmosphere and zero static shear stress (tau(st,0)) states. Then, a series of correction factors are applied on this reference CRR, for the purpose of assessing the variability due to normal effective and static shear stress states (i.e. K-sigma and K-alpha corrections) acting on the horizontal plane. In the literature, a number...
