Excavation Seismology
Abstract
The objective of the program is to develop seismic techniques and equipment which can be used in a hard-rock rapid-excavation system to provide indication of potentially hazardous or changing geologic conditions ahead of the working face. The seismic reflection method is considered the most suitable one for the application. The principal technical problem is identification of reflections superimposed on other source-produced coherent interference. Signal processing techniques such as cross-correlation and velocity filtering or beamforming using an array of receiving sensors are being investigated for enhancement of reflections. The initial part of the program emphasized the development of a seismic source/receiver combination which produces a simple, repeatable transmitted seismic pulse.
