This article examines the impact of electric and electromagnetic fields on the accuracy of GNSS technology, particularly in environments with overhead high-voltage and power lines. Although this factor is often overlooked, it can significantly affect the quality of received signals and, consequently, the accuracy of measurements. Electromagnetic interference caused by the presence of power lines can lead to signal distortions, reduced positioning reliability, and, in some cases, complete signal loss. The study foc...

As a result of mining activity on the earth?s surface the phenomena that have negative effect on the objects in area of influence of extracted area exist. Depending on geomechanical qualities of hanging wall and surrounding rocks, geological conditions of depositing, seam and depth of position of deposit, critical angle of influence, way and time course of mining and other parameters the horizontal and vertical movements always appear to a greater or lesser extent. They can be described by inclination, proportiona...

In the opencast coal mining we face the excavation, transport and the storage of a substantial volume of materials. One of the main and regular tasks for surface mines are therefore the calculations of volumes and the monitoring the progress of extraction. The main objective of the measurement is to determine the geographic position of bucket-wheel excavators and lay down their basic geometric parameters, which define their position within three-dimensional space. This way we can monitor, plan and manage mining pr...

This paper has been written in conjunction with a public contract for the restoration of the partially lost and destroyed building documentation of the Church of the Assumption of the Virgin Mary at Hlu?пїЅn-Darkovi?ky in the territory of the Czech Republic, the contracting authority of which was the Roman Catholic Church. The requirement was the complete provision of measurement in the field and the collection of data, their subsequent processing and the interpretation of the results with the subsequent developme...

With the advance of mining to greater depths, the fully protecting safety pillar of shafts is progressively diminishing. Thus a certain part of the mineshaft and of the protected area on the surface is influenced by undermining. In such a case, it is necessary to assess the expected effect of mining on the mineshaft and the surface objects in relation to the preservation of their stability. Subsequently, it is necessary to carry out direct measurements of movements, and, if the case may be, deformations both in th...
