A model of rockburst including geological dynamic conditions and mining
Résumé
Rockburst is one of the most serious disasters which threaten the safety of mining and occur under certain combinations of geologic and mining conditions. A model of fault-slip burst based on energy of rock mass was developed to illuminate the mechanics of rockburst and assess the treatment parameter in underground coal mines. In this model the energy of a fault involved in rockburst is be assumed to be spheroid. The energy of rockburst is from the rock mass of spheroid and rock mass ahead of development. The critical energy condition of rockburst is used for estimate of rockburst occurrence. As an application the advance distance of rockburst treatment ahead of geological structure can be obtained.Références
