Rock-Burst Incidence, Research and Control Measures
W. T. ROBSON
GROUND failure, violent or otherwise, is a problem to be contended with wherever underground operations are carried out. The character and extent of the failure, whether superficial or of more serious proportions, is determined by a number of factors, among which might be mentioned: the depth and dimensions of the underground workings; the types and distribution of wall rocks; structural features of the ore and enclosing rocks; the degree of metamorphism; the dip of the orebody; concentration of mining operations; the rate of mining; the history of the excavations made on the orebody in question.
