ABSTRACT

Many In-Situ AE monitoring projects in rock salt in the past were focused on monitoring of seismicity induced through work processes such as backfilling (Spies et al. 2005, Becker et. al. 2010), excavation (Eisenblätter et al. 1998), or gas/fluid injection (Manthei et al. 2012). Many processes monitored and analyzed were limited to small rock volumes.
