Summary: The communication needs for rescue operations of trapped miners has recently motivated the creation of throughthe- earth communication systems, which are also envisaged for enabling autonomous mining operations. Because of the large attenuation of radio frequency waves in this propagation medium, these systems usually employ transmission through magnetic induction using very low frequencies. In this paper we presente an overview of the possible applications but also of the technical hurdles faced in this type of communications system. We present a model of a TTE transmission system and discuss some modulation and digital transmission approaches for this medium.
