Coal deep drilling while-drilling data real-time wireless receiving method and system

The invention provides a coal deep drilling while-drilling data real-time wireless receiving method and system. The coal deep drilling while-drilling data real-time wireless receiving method mainly adopts the following steps to process received electromagnetic signals that S1, a high-pass filter is adopted to suppress natural potential and magnetotelluric signals with frequency 0.1 Hz or below; S2, the amplitude of a power frequency interference signal is reduced to be a millivolt level or below by adopting a first-stage low-pass filter; S3, the power frequency interference signal is suppressed by using a secondary low-pass filter; S4, a power supply noise signal is suppressed by adopting a three-stage low-pass filter; and S5, a digital filter is used for suppressing out-of-band noise. According to the coal deep drilling while-drilling data real-time wireless receiving method and system, interference noise signals can be effectively suppressed, so that useful electromagnetic communication signals are extracte
