Abstract
Method and equipment for detection of weakened anchors in underground mining excavations by spectral analysis of the response to impact influence are considered. Computer simulation is performed and dependences of changes in spectral characteristics on the degree of the anchorand-rock contact are established. Distances between cluster centers in a 7-dimensional parameter space (mean square root values of spectral component ranges within seven bands of predetermined frequencies) are used for anchor identification.
