Description

At least in the first phase, there is a direct connection between the introduction of the caustic soda solution into the mine and the appearance of microseismic events. One can also see that with a nearly constant rate of flooding during the months of May to September 1984, the number of activities occurring daily decreases constantly. Due to measurements in a cavern, there was a stop of flooding in the first half of October. The backfilling at a nearly constant rate again led to a more active phase, compared with the previous period, but not on the scale of the measurements at the start. (orig./PW)

Abstract (German)

Es besteht, zumindest in der ersten Phase, ein unmittelbarer deutlicher Zusammenhang zwischen dem Einleiten der Lauge in die Abbaue des Bergwerks und dem massiven Auftreten von mikroseismischen Ereignissen. Weiterhin laesst sich erkennen, dass bei fast konstanter Flutungsrate, in den Monaten Mai bis September 1984, die Anzahl der taeglich auftretenden Aktivitaeten konstant abnimmt. Aufgrund einer Kavernenvermessung kam es in der ersten Oktoberhaelfte zu einem Flutungsstop. Das Wiedereinsetzen der Befuellung mit annaehernd konstanten Raten fuehrte gegenueber dem vorherigen Zeitraum zwar erneut zu einer deutlich aktiveren Phase, jedoch nicht im Massstab der zu Beginn der Messungen gemachten Beobachtungen. (orig./PW)
