The design features of support systems for longwall panel roadways and of coal pillars are discussed in detail. The main support design methods such as empirical, numerical, and analytical methods are described. Ground-reaction curve approach for main gallery design is also presented. The widely used numerical modeling methods are presented. Monitoring techniques used to evaluate the performance of the designed support systems are given. Finally, the general guidelines for safe and economical support system and pillar design for underground coal mining are drawn.

Permanent support design for an existing drainage tunnel at ELİ mine in Turkey
Karpuz, Celal (null; 2007-12-11)
In this study, the results of a new permanent support system design for the re-use of an existing mine drainage tunnel driven through marl rock unit is presented. The tunnel which is 1050 meters long was driven by drilling and blasting and temporarily supported by I section steel sets about two years ago. It is now planned by the mine management to be used as a transportation tunnel for many years. Along the tunnel route, two different rock mass units which were named as marl and graywacke units were en...
Deformation analysis of concrete faced Aydın Karacasu dam and comparison of theoretical results with measurements
Tosun Tütüncübaşı, Tuğçe; Özkan, Yener Mehmet; Yıldız, Saadet Gülru; Çokça, Erdal (2019-01-01)
The improvement in design technologies has enhanced the use of different fill materials in construction of the embankment dams. Rockfill is one of the most preferred fill materials for embankment dam. Also, use of different fill material such as sand-gravel has been preferred in recent years. Previous studies on concrete faced sand-gravel fill dam (CFSGD), results of the laboratory experiments and in-situ testing analysis display that using sand-gravel as a fill material is not only cost-effective but also ...

Failure analysis of thin spray-on liner coated rock cores
Öztürk, Hasan (2017-09-01)
Thin spray-on liners (TSLs) are surface support materials used in mining and civil engineering projects since 1990s with a wide ranging area of application from bolt/mesh support replacement to pillar reinforcement systems. This study presents the investigation of pillar reinforcement capacity of the TSL coated andesite rock core by compression test to mimic pillar reinforcement effect. The uniaxial compressive strength (UCS), modulus of elasticity (E), and energy absorbance capacity of uncoated and 5 mm co...
Towards more reliable and cost effective superconducting generators for wind turbines
Keysan, Ozan; Burchell, J.; Mueller, M.A. (2014-01-01)
For large(~10 MW) wind turbines, direct-drive superconducting generators are proposed to reduce the tower head mass, which help to reduce the installation costs. Most of the existing designs has a very similar topology: a synchronous machine with a rotating superconducting field winding. However, this topology may not be the most suitable design for harsh offshore conditions. A novel transverse flux design is presented in this paper. The design has stationary and modular superconducting field windings combi...
