In TEM detection, there are often additional effects. the paper, from the theory and test, studied the effect of the addi- tional features and detecting characteristics of the curve, and on the basis of these characteristics, the actual engi- neering analysis and interpretation were carried out, drilling verified that mined-out area with water was well lo- calized. Key words: TEM; additional effects; mine water mined-out area ; detection
