| Abstract: | Starting from the dangers of coal mining goaf and the practical significance of de- tection, this paper introduces the principle of TEM detection and the application status of detecting coal mining goals. According to the sorts of goals which are found in the produc tion and general electrical abnormalities, we categorize the coal mining goals, and summa- rize the general methods of goal positioning interpretation. We also offer examples to prove practicality and effectiveness of the methods. The paper is aimed at providing guidance for detecting coal mining goals in future. |
