Abstract
This report describes a 1-year program of exploratory research to determine the feasibility of radar exploration in advance of coal mining. Advance detection of obstructions including faults, clay veins, abandoned wells, and pyrite concretions would improve the safety and efficiency of mining. Using a proprietary, experimental, VHF short-pulse "mining radar" system, two cycles of field testing and equipment improvement were completed. Measurements were made in three bituminous coal mines, a quarry, and a salt mine. Comparisons were made with ground-penetrating radar equipment previously developed for salt dome exploration and for military tunnel detection. The proprietary mining radar equipment and techniques used were found to be the most effective known for coal exploration. However, further improvements were needed. The results and experience gained during the project affirmed the feasibility of the method.
