The general purpose of seismic acquisition is to give the research-worker knowledge about the various strata beneath the earth’s surface. The seismic exploration is based on the recording of reflected seismic waves generated from vibrators and deployed directly onto the ground via hydromechanic pads, mounted for the vibrators. The vibrator vibrates through predetermined points, known as “source” points. The registration of the reflected waves is commited also at predetermined positions, known as “receiverв...

The application of precise geodetic measurements in industrial surveying is very important in defining the axes or planes in which individual parts of equipment are installed in the process of their assembling. Apart from that, it is necessary to control the whole or some parts of equipment after assembling and putting it into operation for the purpose of obtaining high quality operational procedure. This paper describes the procedure of applying precise geodetic measurements and measuring data processing on speci...

The “Pecine” Tunnel is located on the Croatian national road D404 which connects the centre of city Rijeka and Su\vsak port with the Rijeka Bypass. Because of many specificities, namely, three-lane and four-lane sections, two connections, tunnel’s location near the residential area and railway, it was required special approach to its construction. In this paper geodetic procedure and the results of stake out supervising of some tunnel elements, cross profile surveying, as well as verification and adjustment ...

The calibration of the geodetic apparatus is nowadays viewed as common. It is recommended to test it as soon as the new apparatus has been purchased, as it is necessary to find out whether the apparatus meets the parameters declared by the manufacturer. It is also necessary to test it at regular intervals (during the period of two or three years), after it has been repaired, or if any deviation has been found during the process of surveying. The testing of geodetics apparatus are preceded in such a way they corres...

One of the major concerns in all underground mine excavations is the stability of the stopes, the empty spaces which are created throughout the excavation process. Typically, the mining engineer supports or reinforces the stopes when needed, by means of rockbolts, wire meshes and steel sets. At the same time, a monitoring system based on geotechnical or geodetic measurements can provide against tiny displacements of control targets. This paper presents the application of artificial intelligence techniques, namely,...
