Taylor, F.J., 1971. L099 Moura Coalfield seismic reflection survey, QLD, 1970. Record  . Geoscience Australia, Canberra.

Abstract

Some experimental geophysical work was undertaken by the Bureau of Mineral Resources at the Moura Coalfield in Queensland in order to investigate the structure of coal seams which lie within 1000 feet of the surface. The aim of the survey was to evaluate the use of geophysical techniques for locating faults of small displacement. Most of the effort was concentrated on shallow seismic reflection techniques but additional techniques (magnetic, gravity, resistivity, electromagnetic and induced polarization) were used. The whole area of the survey was covered with a close-spaced grid of gravity and magnetic stations. A lesser effort was devoted to resistivity, electromagnetic, and induced polarization methods, the object being to take advantage of the opportunity to tryout these relatively inexpensive methods in the hope that they might give some indications of fault locations. These methods will be evaluated in a separate Record; this one deals- with the results of the seismic work. Encouraging results were obtained from seismic reflection work. The uppermost economic coal seam was mapped to within 300 feet of the surface and areas of faulting could be deduced from time differences and lack of continuity in reflections.

Lineage

The Moura coal district is situated 100-miles west of Gladstone in Queensland. It is a part of the Bowen Coal Basin and has extensive reserves of coal available for both open-cut and underground mining. The Queensland Mines Department issued a contract in 1968 for a seismic reflection survey around Moura with one aim being the location of faults in coal seams; The results of the survey, were disappointing in this regard. It was thought that part of the failure rested with the techniques applied in so far as conventional reflection methods, used for deep petroleum exploration, were applied to regions where the reflecting horizon of interest is less than 1000 feet below ground level. Essentially the contract survey suffered from a lack of concentration on the problems associated with shallow seismic reflection work. As a result the Bureau of Mineral Resources agreed to undertake some experimental work in seismic reflection and also to investigate the possibility of using other geophysical techniques in order to locate faults. The program was carried out in March, April, and May 1970 by officers from the Geophysical Branch of BMR.
