Abstract

Sposób analizy struktury geologicznej i względnych zmian naprężeń w warstwach usytuowanych nad wyrobiskami górniczymi kopalni głębinowej polegający na tym, że do stacjonarnego centrum przetwarzania (1) przekazywane są dane z mobilnego rejestratora danych pomiarowych (3) oraz z centralnej stacji kopalnianego systemu sejsmicznego (10) uzyskiwane w wyniku ściśle skorelowanej czasowo rejestracji niskoczęstotliwościowych szumów sejsmicznych (Dn.cz.) z systemu powierzchniowego oraz wstrząsów sejsmicznych generowanych eksploatacją górniczą (Dw.cz.). Następnie zarejestrowane dane pomiarowe w oknach czasowych, korzystnie 30 sekundowych, w postaci trójskładowych rejestracji niskoczęstotliwościowych szumów sejsmicznych (Dn.cz.) i wstrząsów sejsmicznych generowanych eksploatacją górniczą (Dw.cz.) podlegają przetwarzaniu z zastosowaniem metody interferometrii sejsmicznej dla zapisów szumowych oraz tomografii pasywnej prędkościowej i/lub tłumieniowej dla zapisów wstrząsów kopalnianych. Następnie na tej podstawie wyznaczane są dla badanego obszaru górotworu (7) izolinie prędkości fali poprzecznej oraz izolinie prędkości i/lub tłumienia fali podłużnej w metodzie tomografii pasywnej prędkościowej i/lub tłumieniowej, które w efekcie końcowym odwzorowują uśredniony stan względnych zmian naprężeń w warstwach usytuowanych nad wyrobiskami górniczymi (B). Przy czym, w momencie wystąpienia wstrząsu górniczego (W) następuje korelacja parametrów lokalizacji współrzędnych (X, Y i Z) i wyliczonego czasu (To) wystąpienia tego w ognisku, z czasami pierwszych wejść fali podłużnej generowanej przez niego w zapisach niskoczęstotliwościowych trójskładowych stacji pomiarowych (5) rejestrowanych na powierzchni kopalni oraz odpowiadających im czasów narastania sygnału od pierwszego wejścia fali podłużnej do chwili osiągnięcia przez rejestrowany sygnał zapisu wstrząsu (W) pierwszego maksimum w każdej stacji pomiarowej (5). W układzie stacjonarne centrum przetwarzania (1) połączone jest z jednej strony, korzystnie poprzez modem łączności GSM (2) z mobilnym rejestratorem danych pomiarowych (3), a z drugiej strony z centralną stacją kopalnianego systemu sejsmicznego (10), która połączona jest z zegarem (GPS) i z modułem wizualno - sygnalizacyjnym (11) oraz poprzez układ iskrobezpiecznej transmisji cyfrowej (12) i kopalnianą sieć teletransmisyjną (13) z dołowymi stacjami sejsmometrycznymi i/lub z sejsmicznymi stacjami geofonowymi.The method of analyzing the geological structure and relative changes in stress in the layers located above the mining excavations of the underground mine consists in the fact that data from the mobile measurement data recorder (3) and from the central station of the mine seismic system (10) obtained to the stationary processing center (1) as a result of closely time-correlated registration of low-frequency seismic noise (Dn.) from the surface system and seismic shocks generated by mining operations (Dw.cz.). Then recorded measurement data in time windows, preferably 30 seconds, in the form of three-component recording of low-frequency seismic noise (Dn) and seismic shocks generated by mining operations (BW) are processed using the seismic interferometry method for noise recording and passive tomography velocity and / or damping for mine tremor records. Then, on this basis, the isoline of the transverse wave velocity as well as the isoline of velocity and / or suppression of the longitudinal wave in the passive tomography and / or attenuation tomography method are determined for the studied rock mass (7), which in the end reflect the average state of relative stress changes in the layers located above mining excavations (B). At the same time, when the mining shock (W) occurs, the parameters of coordinate location (X, Y and Z) and the calculated time (To) of this occurrence in the focus correlate with the times of the first longitudinal wave inputs generated by him in the records of low-frequency three-component measuring stations ( 5) recorded on the surface of the mine and the corresponding signal rise times from the first longitudinal wave input until the recorded shock recording signal (W) reaches the first maximum at each measuring station (5). In the system, the stationary processing center (1) is connected on one side, preferably via a GSM communication modem (2) with a mobile measurement data recorder (3), and on the other with a central mine seismic system station (10), which is connected to a clock ( GPS) and with the visual-signaling module (11) and through the intrinsically safe digital transmission system (12) and the mine teletransmission network (13) with underground seismometric stations and / or with seismic geophone stations.
