Abstract

The paper deals with a brief geological and historical introduction of Ostrava-Karvina coalfield (OKC), which is followed by details about the rocks tested; macroscopic and microscopic petro-graphic characterization, their physical and geophysical properties obtained from laboratory seismic measurement. The rock specimens used to test their geophysical properties were representative of all kinds of rock samples from borehole Darkov 265-01. To find out possible relations with geophysical and physical properties, and to discover the fatigue properties of the rock, all these rock specimens (37 in total) were tested under the same-identical dynamic cyclic loading conditions of 1 Hz frequency and 0.1 mm amplitude using ramp waveform. The findings and various relations obtained from laboratory investigations are reported.
