If events at an underground mining operation trap a miner or group of miners, the Mine Safety and Health Administration (MSHA) can deploy the Trapped Miner Seismic Location System to help determine the underground location(s) of the trapped miners(s). The system can utilize miner-generated seismic signals as a means to communicate proof-of-life and location to surface operations. The system is comprised of multiple surface arrays. Each array includes a set of geophones, radio telemetry, digitizer, GPS antenna and a power supply. The arrays communicate digitized seismic data to remote computers for processing. Processing removes interference to facilitate detection and origin of the miner-generated seismic signals.
