Analysis of Drift Convergence Phenomena from G-Tunnel Welded Tuff Mining Evaluations

摘要

This paper discusses the results of vertical and horizontal drift convergence measurements taken during the mining of a respository-sized drift in welded tuff in G-Tunnel on the Nevada Test Site. Results are quantified in terms of drift convergence magnitudes and rates that relate to drift stability. 10 refs., 4 figs. (ERA citation 12:028415)
