Design, measurement and analysis of gyro-azimuths influence on the results of aligning the underground control network

Abstract: The article discusses the impact of additionally measured gyroazimuths on the accuracy of the underground network. It discusses such issues as: the way of gyroazimuth measurement, corrections introduced into the measured gyroazimuth, eff ects of centering the instrument and signal and eff ects of side lengths for accuracy of gyroazimuth measurement, the legal basis for such measurement in mining excavations and design quantities and location of gyroazimuth measurement in the underground network to obtain its b… Show more

“…In case of the applied gyrotheodolite, among the available methods, the "Follow" method was chosen, i.e., return points (Instrukcja…, 2011) and two measurements from each of two ends of the line, choosing the longest possible line. A particular attention was paid on the accuracy of centering the instrument and signals, because the participation of this error in the azimuth error is significant (Szafarczyk et al, 2017).…”
