Abstract Anti-interference measures must be adopted in coalfield where noise level is heavy to guarantee the quality of data collected. The evaluation of parameters is necessary for understanding the effectiveness of the measures. TEM S/N and its calculation method are given in this paper to evaluate the effectiveness of the anti-interference measures. The TEM S/N data were statistically analyzed by using field data processed with different measures, and the result shows that the S/N parameter can display the effectiveness reasonably and the calculation is easy.
