Description

Die; Erfindung betrifft ein, Verfahren zum Auffinden und zur Lagebestimmung von bodenschätzen, insbesondere von erzgängen, Kohleflözen und anderen Lagerstätten von geringer Mächtigkeit und Ausdehnung durch Ermittlung und Lagebestimmung von Grenzflächen in; Gebirgsschichten mittels künstlicher, elastischer Bodenwellen. The; The invention relates to a method for locating and determining the position of mineral resources, especially of ore veins, coal seams and other deposits of small thickness and extent by determining and determining the position of Interfaces in; Mountain layers by means of artificial, elastic bumps.

Bekanntlich werden künstluche, clastische Bodenwellen, die von einem Schlußpunkt ausgehen, beim Durchgang durch eine Grenzfläche zweier Medien von verschiedener Fortpflanzungsgegschwindigkeit in longitudinale und transversale Wellen aufgespalten. Jede dieser Wellen pflanzt sich mit der ihr in, dem betreffenden Medium eigenen Geschwindigkeit fort Es. ist auch bekannt, die aufgespaltenen Wellen mit Hilfe von mehreren für longitudinale und transversale Wellen empfindlichen Seismographen, die auf der Rückseite der Grenzfläche in radialer Richtung vom Schlußpunkt hintereinander aufgestellt sind, aufzuzeichnen. Bei Kenntnis mindestens einer Fortpflanzungsgeschwindigkeit der Bodenwellen läßt sich auf diese Weise die Lage der Grenzfläche ermitteln. It is well known that artificial, clastic bumps caused by a Exit point when passing through an interface between two media of different Propagation speed split into longitudinal and transverse waves. Each of these waves is planted with its own in the medium in question Speed on it. is also known to use the split waves several seismographs sensitive to longitudinal and transverse waves, those on the back of the interface in the radial direction from the end point one behind the other are set up to record. If at least one speed of propagation is known of the bumps can be determined in this way the position of the interface.

Hier setzt die Erfindung ein mit dem Vorschlag, die sich mit der Entfernung von der Grenzfläche vergrößernden, aus den Einsätzen der longitudinalen und transversalen Wellenfranten sich ergebenden Laufzeitdifferenzen zwischen, den longitudinalen un.d transversalen Bodenwellen zu registrieren un.d auszuwerten. Verbindet man n.ämlich die Einsatzzeiten durch eine Gerade, so liegt der Schnittpunkt der Laufzeitkurven an der Stelle der Grenzfläche. Ohne Kenntnis einer Fortpflanzungsgeschwin.digkeit führt somit das erfindungsge.mäße Verfahren zur Lösung der gestellten Aufgabe. This is where the invention begins with the proposal that deals with the Enlarging distance from the interface, from the inserts of the longitudinal and transversal wave fringes resulting time differences between, the to register and evaluate longitudinal and transverse bumps. If you connect the operating times with a straight line, the point of intersection lies of the transit time curves at the point of the interface. Without knowledge of a reproductive speed thus leads the method according to the invention to solve the problem.

An, Hand der Abb. 1 und. 2 wird d.as erfin.dungsgemäße Verfahren näher erläutert. In der Abb. I gehen von einem Schußpunkt Wellen aus, die beim Durchgang durch die Grenzflöche p in longitudinale und transversale Wellen aufgesolittert werden. Die in radialer Richtung vom Schlußpunkt auf der Rückseite der Grenzfläche p aufgestellten Seismographen werden zuerst von der Wellen front der Longitudinalwellen un.d sodann. von. der Wellenfront der Trausversalwellen getroffen. Der Zeitpunkt de!s Eintreffens der Wellen wird von den Seismographen. registriert, und die Einsatzzeiten werden als Funktion. des Ortes in einer Laufzeitkurve aufgetragen (Abb. 2). Velrbindet man die Einsatzzeiten durch Gerade, sol schneiden sich die Geraden im Punkt p1, der dem Punkt p entspricht, an dem die Verlängerung der Seismographenlinie die gesuchte: Gnenzfläche schneidet. An, hand of Fig. 1 and. 2 is the method according to the invention explained in more detail. In Fig. I, waves emanate from a shot point, which when passing through separated into longitudinal and transverse waves by the boundary surface p will. The one in the radial direction from the end point on the back of the interface p installed seismographs are first of the wave front of the longitudinal waves and then. from. hit the wave front of the Trausversalwellen. Point of time de! s arrival of the waves is indicated by the seismograph. registered, and the operating times are as a function. of the location plotted in a transit time curve (Fig. 2). Velrbindet the operating times by straight line, so the straight lines intersect at point p1, which corresponds to the point p at which the extension of the seismograph line is the one you are looking for: Surface intersects.

Für die: Anwendung des Verfahrens gemäß der Erfindung ist es ohne Bedeutung, welche Lage im Ranm die Meßstrecke einnimmt. For: Application of the method according to the invention is without Meaning which position in the Ranm the measuring section assumes.
