A system for transmitting telemetry data between an underground structure and a location above the underground structure includes a network of receiving devices within the underground structure which gathers telemetry data from a data transmitter located within the underground structure. An underground broadcasting station in communication with the network of receiving devices includes an underground processing device for converting the telemetry data into an encoded impactor signal and a seismic generator in contact with the underground structure and driven by the encoded impactor signal to broadcast an encoded seismic signal through an adjacent earthen formation. The system includes a receiving station having a seismic sensor and a processing device. The seismic sensor is in contact with the earthen formation at a remote location substantially above the underground structure. The processing device is in communication with seismic sensor and can convert the received encoded seismic signal into telemetry data.
