Abstract:

Noise and abnormal superposition effect usually contained in IP anomaly data，how to effectively isolate the exception information，improve the IP anomaly indoor processing efficiency and the level of explanation，is an important link of IP anomaly interpretation.In data processing method，the wavelet transform is a new mathematical theory and methods developed in the mid-1980s，it has a good nature of  local analysis in the space domain and frequency domain at the same time，the signal can be broken down into a variety of different frequency or scale ingredients，using the above characteristics of wavelet transform，we can get a variety of abnormal in the sense of scales based on the IP anomaly classification.The application of wavelet analysis method in a mining area of Henan Province in ladder IP anomaly data processing，to distinguish noise and surface shallow geological interference anomaly，deep source or larger scale geological background abnormalities，highlighting the ore anomaly information，finally obtain better data processing effect.
