    Analiza odpowiedzi sejsmicznej modelu spągu warstw cechsztynu i paleowydm czerwonego spągowca w celu określenia parametrów rejestracji, przetwarzania i kryteriów interpretacyjnych dla potrzeb kopalni miedzi Polkowice-Sieroszowice

    In the LGOM area were observed Rotliegend dunes, which made difficult to effective minning. In order to solve of the stated problem in the paper, marked out profile of a length of 800 [m] in the drift PS-0 in the copper mine Polkowice-Sieroszowice. Collected geological data from wells Ra20-G34, Jm16-G36, Jm16-G35 and physical properties of rocks from the borehole S-241a were used to construct models. Acquisition parameters were determined to common midpoint stacking method. Simulation of seismic recording obtained in a result of the finite difference method modeling. The obtained synthetic records form the basis of seismic processing. During subsequent processing procedures have been removed direct waves and derived from them noise. In ?-p domain applied predictive deconvolution to attenuate multiple waves. Then the interactive velocity analysis was performed using the constant velocity stack method. The final step at this stage was the summing of records and processing after stack. The results were synthetic sections, which for criteria of the interpretation determined from specific geological structures.
