【 摘 要 】

Work has progressed on both subsystems: the through-the-earth (TTE) system and the In-Mine Power Line (IMPL) system. After the Lab prototype of the IMPL system was perfected to function satisfactorily, the thrust of the work focused on building a first production prototype that can be installed and tested inside a mine. To obtain multi-channel voice communication through the TTE system, effort has proceeded to compress voice messages and make the format compatible with the power-line interface protocol.
