Improvement of methods for recognising and treating the zones at risk from rock bursts
Methods for recognising and controlling dynamic phenomena have evolved in recent years with the development of the following phenomena in French coal mines: (i) roads serving the workings; (ii) headings; (iii) pillars which are generally present when a face is started. The two objectives of this research were the prediction of these new phenomena and their prevention. To achieve these objectives it has been necessary to record the phenomena and to find a correlation between their occurrence and the natural working environment in which they occur. Mathematical models have been created for the purpose of understanding mechanisms and explaining configurations. An attempt has been made to adapt traditional methods of prediction to the new conditions and to develop new methods of prevention.
