Abstract

Groundwater level changes caused by influence of mining tremors – case study from the Rydu³towy Mine Area (Poland).A b s t r a c t. In 2018, as part of the implementation of a European project: European Plate Observing System (EPOS-PL), a hydrological monitoring system was installed in a Rybnik test site. The system is configured to measure changes of groundwater level caused by seismic events which were induced by mining exploitation. The piezometers were drilled within an active mining area, in close vicinity to mining longwalls of the Rydułtowy Coal Mine, an industrial partner in the project. The paper presents the state of knowledge on the phenomena of co-seismicity in hydrology, a description of installed measuring system, and the first hydrographs registered for mining tremors with a local magnitude from 2.7 to 3.1, which occurred up to 3 km away from the location of piezometers.
