This report describes results of a one-and-half year investigation toward the definition of the microseismic data detection and acquisition system, and the data processing procedures for application to Abandoned Mined Lands stability problems. The investigation on natural phenomena using surface and/or underground arrays was conducted at the Southfield Mine near Florence, and in the Foidel Creek Mine near Oak Creek, both in Colorado. The surface monitoring of impact sources in an underground tunnel as conducted in the Otay Mesa Tunnel Site near San Diego, California. Many of the observations and conclusions are applicable to stability control in active mines, underground storage reservoirs, waste repositories, dams, embankments, bridges, and foundations.
