Abstract: A system and method for communications in a mine provides for seismic wave generation through mine strata which may include specific location identification within the mine can be used in emergency situations by trapped miners. A seismic transmitting transducer may impart seismic waves onto a rod embedded into the strata, which is tunable by use of a slideable manifold that couple the transducer to a rod. Likewise, a receiving transducer which may also be coupled to a rod via a manifold may be configured to receive the seismic wave. The seismic wave may be modulated to produce a message or portion of a message that may be decoded at the receiving location. The transducers may be configured to utilize frequency hopping spread spectrum techniques. A geophone may be used as the receiving transducer.
