摘要
文中用花岗岩、闪长岩和大理岩通过双向加载系统模拟了地下巷道岩爆的发生,用扫描电镜对试件断口进行分析,研究了岩爆的发生机制;并用声发射检测系统记录了岩爆发生过程中的声发射特性,提出了岩爆的预测方法。
Taking theGranite, diorite and marble as the test piece, a simulation is made of rockOut burst in underground roadways with the bi-directional loading systemAn analysis is made of the fracture of test piece by using the scanningElectron microscope. Mechanism of rock outburst is studied; and theAcoustic emission detecting system is used to record the acousticEmission characteristics during the rock out burst. A method forPredicting rock outburst is introduced
