Connecting Surveys and Orientation Measurements in Čsa 2 and Mír 5 Shafts

Original language description

Connecting surveys and orientation measurements in the ČSA 2 and Mír 5 shafts were carried out in order to determine their positions in relation to each other and the positions of these two underground mining works in relation to structures situated on the surface. The measurements were carried out during the completion of the connecting underground crosscut between the Karviná and Darkov Mines, with an anticipated length of 3,100 metres. This is a very complex issue involving the most precise measurement and calculation techniques in mine surveying, especially as to achieving the necessary accuracy, which is mostly defined by the longitudinal and transverse deviations of the ?cut-through? or ?breakthrough?. The project engineer determined the requiredaccuracy as a maximum deviation (longitudinal, transverse) of 0.250 metres for all cut-through options (special accuracy). The entire measurement process included surface measurements, depth measurements of both connected horizons (Mír 5
