The invention discloses a satellite ephemeris injection method for mine satellite navigation and positioning, belongs to the technical field of wireless communication, and is mainly applied to surface mines and ports. According to the satellite ephemeris injection method for mine satellite navigation and positioning, the technical problem of long terminal cold start positioning time caused by satellite signal full-sky satellite searching is solved. The satellite ephemeris injection method comprises the following steps: pre-evaluating a first terminal downloading link, a GNSS downloading link and an IGS downloading link in a first terminal so as to screen out downloading links meeting a preset standard; downloading and verifying the broadcast ephemeris data in a first preset time period based on the screened and determined downloading link, and determining effective broadcast ephemeris data based on a verification result; preprocessing the effective broadcast ephemeris data to screen out healthy satellite broa
