Creep Behaviour of a Polymer-based Underground Support Liner

Creep behaviour analysis of thin spray-on liners Güner, Doğukan; Öztürk, Hasan; Department of Mining Engineering (2020) Thin Spray-on Liner (TSL) is a relatively thin (2–5 mm) and fast-setting liner material used by spraying onto rock surfaces to support underground excavations. Areal support materials that are sprayed onto the rock, such as shotcrete or liners, are able to generate support resistance at small rock deformations and can prevent underground rockfalls from happening in the first place. However, where large ground convergence occurs, the more flexible TSLs may provide superior support over the full range of rock...
Implementation of software GPS receiver Günaydın, Ezgi; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2005) A software GPS receiver is a functional GPS receiver in software. It has several advantages compared to its hardware counterparts. For instance, improvements in receiver architecture as well as GPS system structure can be easily adapted to it. Furthermore, interaction between nearby sensors can be coordinated easily. In this thesis, a SGR (software GPS receiver) is presented from a practical point of view. Major components of the SGR are implemented in Matlab environment. Furthermore, some alternative algor...
Generic creep behavior and creep modeling of an aged surface support liner under tension Guner, D.; Gölbaşı, Onur; Öztürk, Hasan (2022-04-01) Polymer-based materials have been motivated to be an alternative support system element in the mining/tunneling industry due to their logistic and geotechnical benefits. Thin spray-on liner (TSL), a term to define the application of the material on the rock surface with a layer ranging from 2 mm to 10 mm in thickness, shows some promising results. TSLs are mainly composed of plastic, polymer, or cement-based ingredients to a certain proportion. This study intends to reveal the time-dependent response of TSL...
Creep modelling study of a surface support liner Güner, Doğukan; Öztürk, Hasan (2018-06-24) Surface supports are widely used in underground excavations. Since conventional surface support liners have inherently-brittle characteristics and require longer curing period, an alternative support system using polymer based surface support liner, thin spray-on liners (TSLs), has been observed to have a promising ductile and fast-curing potential for underground operations. TSLs can exhibit a good performance for highly-stressed, deep, rock bursting conditions as well when used together with rock bolts an...
Status of the VERITAS Observatory Holder, J.; Acciari, V. A.; Aliu, E.; Arlen, T.; Beilicke, M.; Benbow, W.; Bradbury, S. M.; Buckley, J. H.; Bugaev, V.; Butt, Y.; Byrum, K. L.; Cannon, A.; Celik, O.; Cesarini, A.; Ciupik, L.; Chow, Y. C. K.; Cogan, P.; Colin, P.; Cui, W.; et.al. (2009-01-01) VERITAS, an Imaging Atmospheric Cherenkov Telescope (IACT) system for gammma-ray astronomy in the GeV-TeV range, has recently completed its first season of observations with a full array of four telescopes. A number of astrophysical gamma-ray sources have been detected, both galactic and extragalactic, including sources previously unknown at TeV energies. We describe the status of the array and some highlight results, and assess the technical performance, sensitivity and shower reconstruction capabilities.
