Description
Verfahren zur Ermittlung des Aufbaues von Gebirgsschichten. Die Erfindung betrifft eine weitere Ausbildung des Verfahrens zur Ermittlung des Aufbaues von Gebirgsschichten gemäß Patent 371963, bei welcher die in dem Untersuchungsgebiet künstlich erzeugten elastischen Wellen von einem Mikrophon aufgenommen «-erden, (las diese unter Vermittlung des elektrischen Stromes in einem Telephon o. dgl. Gerät hörbar macht: dabei «erden aus der Tonhöhe und aus bezeichnenden Nebenger5uschen die erforderlichen Rückschlüsse auf den Aufbau der Schichten des Untersuchungsgebietes gemacht. Diese Einrichtung eignet sich auf Grund ihrer Einfachheit besonders für die Nachprüfung der nach dein Hauptpatent an-r_ustelletiden Untersuchungen bzw. zu vorläufigen Untersuchungen, um den erforderlichen Oberblick für die sich anschließenden Einzeluntersuchungen mit Hilfe der Arbeits«-eise nach dein Hauptpatent zu gewinnen.Procedure for determining the structure of mountain strata. The invention relates to a further development of the method for determining the structure of Mountain strata according to patent 371963, in which the in the investigation area artificially generated elastic waves picked up by a microphone (read this with the help of the electric current in a telephone or the like. The device makes audible: in the process, grounding from the pitch and from significant background noises the necessary conclusions about the structure of the strata of the study area made. Due to its simplicity, this facility is particularly suitable for the re-examination of the investigations or to preliminary investigations in order to obtain the necessary overview for the subsequent To win individual examinations with the help of the working «way to get your main patent.
Die ini Mikrophon erzeugten Stromschwankungen können auch mittels eines Oszillographen oder ähnlichen Cerätes photographisch aufgezeichnet wer('en, während das Telephon nur zum Abhören dient.The current fluctuations generated in the microphone can also be controlled by means of an oscilloscope or similar device recorded photographically who ('s, while the telephone is only used for eavesdropping.
Die Verwendung eines 1Uikrophons gestattet auch gleichzeitig die Feststellung des Zeitpunktes der künstlichen Erschütterungen, der z. B. aus den durch die Luft übertragenen Schallwellen errechnet wird. Verwendet man -nämlich ein Mikrophon, das sowohl auf den Bodenschall als*auf den Luftschall anspricht, so erhält man nacheinander-zwei Einsätze in der aufgezeichneten Kurve. aus der sich der Zeitpunkt leicht errechnen läßt. Es können natürlich auch zwei Mikrophone, das eine für den Bodenschall, das andere für den Luftschall, an den Oszillogräphen bzw. die Aufschreibevorrichtung angeschlossen werden. -Mit Hilfe dieser Einrichtung erhält man eine bezüglich der Genauigkeit der :Messungen dem Verfahren des Patentes 371963 gleichwertige Arbeitsweise, während aber die hierfür gerauchte Einrichtung noch einfacher und leichter ausfällt.The use of a 1U microphone also allows determination at the same time the time of the artificial vibrations, the z. B. from the through the air transmitted sound waves is calculated. If you use a microphone, that responds to both floor and airborne noise, then you get-two in succession Inserts in the recorded curve. from which the point in time can easily be calculated leaves. Of course, two microphones can also be used, one for the floor noise, that others for airborne sound, on the oscillograph or the writing device be connected. -With the help of this facility, you can get one regarding the Accuracy of: Measurements equivalent to the method of patent 371963, while the facility smoked for this purpose is even simpler and lighter.
