Abstract
This report deals with the results obtained in tests with the electrical resistivity method on the brown coalfields at Morwell and Traralgon, Victoria, in an attempt to develop a rapid method of determining the presence of the coal and its depth below the surface. These tests were carried out in the latter part of 1943 by the Geophysical Section of the Mineral Resources Survey at the request of the Victorian Electricity Commission. Thirty-four resistivity-electrode separation tests were made over a wide variety of geological sections in the parishes of Maryvale, Hazelwood and Loy Yang. These tests were preceded by a number of tests by specific resistivity made on various types of overburden and on coal exposed in the open cuts at Yallourn. This report discusses the results of these tests although verbal information concerning them has already been made available to the Commission's officers. It will be shown that under certain conditions, the predictions of the depth to coal are reliable within fairly narrow limits while under other conditions the predictions are misleading. It is proposed in the first instance to outline the method and apparatus used in these tests. In addition, it is considered advisable to outline the methods of interpretation employed in order that the conclusions reached will by fully appreciated. In addition to discussing the resistivity results, the report deals briefly with the possibility of using gravity methods on the same prospecting problem. Calculations have been made of gravity anomalies to be expected from certain coal sections and it is shown that under favourable conditions this might prove of value in determining the presence and position of the coal.
