Seismic Determination of Geological Discontinuities Ahead of Rapid Excavation
The need for the on-site knowledge of large geological discontinuities ahead of rapid excavation is very desirable for avoiding hazardous or difficult formations ahead of excavation surfaces and for expediting the rate of excavation. The objective of this program is to study the feasibility of using ultrasonic acoustic signals and seismic impulses to rapidly predict the presence of large geological discontinuities or other potential sources of danger, such as old mine workings filled with water or gas, lying within a reasonable working range (a few feet to a few tens-of-feet) ahead of excavation surfaces. The principal geologic medium of interest is 'hard' or crystalline rock. (Author)
