Seismic evaluation of the Carboniferous rock mass destruction in shallow mining regions
Języki publikacji
Abstrakty
Results of seismic investigations are presented in this paper. Investigation were carried out in regions of shallow coal exploitation. In those regions we can observe strongly disturbed zones. In such case seismic measurements show the strong velocity anomalies. Velocity of seismic P wave strongly depends on the cracks density. As a results of investigation a relationship between RQD (Rock Quality Designation), cracks density and P wave velocity is shown. Quality index QI is the best estimator of the real Carboniferous rock mass destruction. As a final result the seismic scale of the Carboniferous rocks evaluation is proposed.
