This research took place at the Nelson Tunnel/Commodore Waste Rock Pile Superfund site in Creede, Colorado. The Nelson Tunnel was constructed to dewater the underground mines along the highly productive Amethyst vein. The collapsed tunnel portal is located on the west side of West Willow Creek about one mile north of the Town of ...
Project Description The behavior, during excavation, of a shallow tunnel cutting densely fractured limestones and dolomites raised concerns. The tunnel is called "Drumanar tunnel‘ and located in Louisville, in Southern Indiana. ...
Abstract A case study of tunnelling in heterogeneous ground conditions has been analysed. The case involves a tunnel excavated in mixed-face conditions, where the main host material was rock, but for a distance of about 30 m, the tunnel had to be driven through a thick layer of soil, primarily moraine and sandy soil materials.During ...
CODEL’s tunnel monitoring products simplify the challenge of sourcing, installing and maintaining a highly accurate and reliable tunnel monitoring solution. ...
Key product features for transportation applications include the following: Wide operating temperature range is suitable for outdoor installation in remote locations. Rugged designs allow operation in locations with high electrical interference. ...

The latest rail line comprises five stretches of tunnel, totaling 33 kilometers (20 miles) of tunnel; it requires approximately 400 workers and relies on equipment such as a tunnel boring machine (TBM) to drill out the tunnel. ...
The performance and size of the tunnel determine amongst other parameters the producible wind strengths. As our wind tunnel reaches its limits with regard to the ultrasonic wind sensor, we needed something bigger to confirm the VENTUS measurement range… WindGuard tunnel in Bremerhaven – basic information In Bremerhaven one of the ...

Designed and performed "piggybacked" gravity traverses above and within the Department of Defense's experimental tunnel at Idaho Springs, Colorado. This graduate school project (Colorado School of Mines) was an attempt to determine the apparent density of the tunnel overburden. Location and elevation surveying was performed at all stations, in ...
Scope This project was conducted to determine the treatability and feasibility of using water flowing from the Spiro Tunnel for municipal supply. The Spiro Tunnel is located to the east of Thaynes Canyon and above Three Kings Drive, adjacent to the Park City Municipal Corporation’s Golf Course Maintenance Facility. Water flowing from the ...
Different modification options were evaluated which include mounting location alteration, mounting damping change and material revision. Results from experimental modal analysis and sound pressure spectrum measurement in a wind tunnel indicate the direction of design modification for reduction of the roof rack noise and vibration. The modal analysis and physical ...
The Etruscan tunnel called Ponte Coperto is located NW of Rome, near the town of Cerveteri. ...
This Roadlog directs you to the meeting location for the first day of the field trip, followed by a description of the route and a short summary of each major stop. ...
LHC is the biggest and the most complex scientific instrument that has been ever made and the particle accelerator of the highest energy all over the world. The accelerator is located into a tunnel at 100 m depth under French and Swiss territory. ...
