摘要

The study concentrates mainly on the development of failure process in composite rock mass. By use of acoustic emission (AE), convergence inspection, pressure monitoring, level measurement techniques and the modern signal analysis technology, as well as scan electron microscopy (SEM) experiment, various aspects of nonlinear dynamic damage of composite rock mass surrounding the transport roadway in Linglong gold mine are discussed. According to the monitoring results, the stability of the rock mass can be synthetically evaluated, and the intrinsic relation between the damage and the characteristic parameters of acoustic emission can be determined. The location of the damage of rock mass can also be detected based on the acoustic emission couple monitoring signals. Finally, the key factors which influence the stability of the transport roadway supported by composite hard rock materials are found out.
