Researchers from the U.S. Bureau of Mines have installed low-cost, personal-computer-based data acquisition systems to monitor mining-induced seismicity and rock mass deformation at three underground hard-rock mines: the Homestake Mine, Lead, SD; the Sunshine Mine, Osburn, ID; and the Lucky Friday Mine, Mullan, ID. The basic components of the systems include geophones, amplifiers, signal-conditioning equipment, and data acquisition hardware and software. Each system is capable of automatically recording and storing full-waveform information from seismic events in the mine. By combining data from these systems with rock mechanics information from the mine, a modified excavation plan may minimize rock burst occurrences and may allow recovery of more resources from highly stressed ground. The process of selecting recording devices, designing system layout, and installing the equipment are described in detail. Examples from the systems at the three mines are included.
