Research Paper (postgraduate) from the year 1990 in the subject Physics - Other, grade: 1,0, Technical University of Clausthal, course: Geophysik, language: English, abstract: With the increasing automation of mining, the underground mining forecourt mining is becoming increasingly important. In order to determine the tectonic content of the apron, a weather-protected measuring system was developed, which detects the position of disturbances by seismic channel waves.
There are two methods for mapping:
1. The Through-Transmission Measurement provides information about a fault in the seam
2. The reflection measurement provides information about the situation.
A great sense of accuracy can be achieved with combined use of both methods. The analysis of 111 measurements shows that geological conditions made the accuracy of the measurements very good, while in geologically complex structures the location of the disturbance proved to be very difficult.
The loss of resolution associated with envelope formation prevents the detection of clutter. To remedy this situation, the reflected Flözwellenzug must be attributed to a needle pulse. Theoretical investigations confirm this approach.
Since flute waves are subject to absorption - the higher the frequency, the stronger the absorption - and the loss of energy in reflection occurs, research in this area still needs to be done in order to use the insights gained in data processing. Remedies cause a spatial distribution of energy and thus complicate the indication of a possible disorder. This shows that complex geological structures have to be further investigated by model seismic investigations. This requirement is underlined by the high costs of underground measurement, which depending on the length of the track to be measured amount to 50,000 DM to 150,000 DM
