The need for the on-site knowledge of large geological discontinuities ahead of rapid excavation is very desirable so that hazardous or difficult formations ahead of an excavation face can be avoided or prepared for. Such information could result in fewer machine breakdowns, proper preparation for entry into zones where special precautions must be taken, and considerable savings in cost and human resources. 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 ahead of excavation surfaces. The principle geologic medium of interest is hard or crystalline rock.
