A Note on Physical Modeling Approach for Assessment of Excavation Techniques
With the growing interest in utilizing underground space, the need for quantitative and qualitative assessment of excavation techniques to dictate the best choice for mining is now becoming...
1992: When Things Began to Move at Yucca Mountain
This paper examines progress made on the Yucca Mountain Site Characterization Project (YMP) during 1992 and continuing into 1993. In addition, it discusses and describes design work on...
Mine Support, Radiation and Ventilation Control with Spray-on Barriers
The use of spray-on liner agents to provide localized excavation support in place of traditional techniques such as shotcrete or bolts-and-screen has been the subject of extensive investigation....
Cycletime Simulation of Shield-Tunneling Operation
Computer simulation...
Design of Pre-excavated Scour Hole Below Flip Bucket Spillways
A number of tests were performed on a model-scale flip bucket spillway with a gravel-bed plunge pool in order to develop equations to describe the geometry of the scour hole created by...
Microtunneling: Overview and Case Study
Microtunneling is defined in the United States as a remotely controlled, laser guided pipe jacking process, which does not require personnel entry. This paper describes the components...
Designing Reinforced Rock
The reinforced rock arch design method has been used to stabilize coal mine excavations for 40 years, but so far has been applied to only a few tunnels. The use of rock reinforcement develops...
Mobile Continuous Lunar Excavation
The purpose of this paper is to explore the two main problems regarding current approaches to lunar mining and to recommend three candidate solutions which will be shown to have potentially...
Transfer of Terrestrial Technology for Lunar Mining
Terrestrial mining equipment was evaluated for development of concepts and their application to lunar-based mining operations. The major operational differences between terrestrial and...
Principles of Control for Robotic Excavation
Excavation can be considered one of the most unstructured problems in the construction environment. On one hand, many technologies have been developed in the past to build shelters using...
Excavation and Support for the Urban Infrastructure
This proceedings,
In Too Deep
Urban excavation is fraught with risks and potential liability for engineers and contractors. Environmental issues (such as Superfund regulations and environmental impact statements),...
Mining for Building Expansion
Engineers adapted mining techniques to tunnel under a vibration sensitive manufacturing operation to create new working space below. IBM workers needed more working space at their Vermont...
Building Beneath Boston
Up/down construction is a method in which a project's substructure and superstructure are simultaneously built. The substructure's wall, column and foundation...
Mechanical Excavator Performance in Yucca Mountain Tuffs
A research effort of four phases is in progress at the Colorado School of Mines. The overall program will evaluate the cutability of welded tuff and other lithologies likely to be excavated...
The Adoption of Mechanized Excavation Techniques for the Superconducting Super Collider
The Superconducting Super Collider (SSC) is the latest and largest in a line of high-energy physics accelerator projects. The five increasingly energetic accelerators which make up the...
The Shaft Excavation Effect Experiment
The Shaft Excavation Effect (SEE) experiment has been carried out by Power Reactor and Nuclear Fuel Development Corporation (PNC). Corresponding to this experiment, an evaluation system...
Modelling of Excavation, Thermal Loading and Bentonite Swelling Pressure for a Waste Repository
For the performance assessment of a future nuclear waste repository, the excavation of the tunnel and deposition hole, thermal loading from waste heat release and the swelling pressure...
Archaeological Program for the Yucca Mountain Site
Archaeological surveys, limited surface collections and selected test excavations in the Yucca Mountain Project Area have revealed four distinct aboriginal hunting and gathering adaptive...
The Technical Challenge of Mechanized Excavation for Nuclear Waste Repositories
The requirements of mechanized tunnelling and shafting techniques within this newly developing field, namely the excavation of Nuclear Waste Repositories, will challenge the designers...
