The invention discloses a mining user identification method, system and device and a medium, and the method comprises the steps: obtaining the monthly average power consumption of a plurality of target users, and selecting the target user with the monthly average power consumption greater than a preset power consumption threshold value as a suspected mining user; and collecting a current signal at the head end of the feeder line at the suspected mining user side and a voltage signal at the accessed common coupling point. Harmonic signal extraction is carried out by adopting the voltage signal and the current signal to generate a first harmonic signal and a higher harmonic signal; and performing feature extraction by using the first harmonic signal and the higher harmonic signal to obtain a higher harmonic feature. And finally, performing feature matching by adopting higher harmonic features, thereby screening out mining users from the suspected mining users. Compared with a method for detecting ...
