3-D Numerical Modeling and Study of Mine Tremors Associated with Coal Mining in the Vicinity of Major Faults (An extended abstract)

摘要

The objective of the paper is to discuss the results of geomechanical research into rock mass behaviour, where multi-seam coal extraction is conducted in the vicinity of major faults. The research was undertaken to verify the hypothesis of such faults being a possible source of intense rock mass tremors which in turn lead to rockbursts. The investigation was occasioned by the tragic consequences of the rockburst that occurred at 13:57 on September 11, 1995, in the vicinity of Fault III in Nowy Wirek Colliery (in the autumn of 1995 Nowy Wirek Colliery merged with Polska Colliery, henceforth became known as Polska-Wirek Colliery), the Upper Silesia Coal Basin, Poland.
