| 摘 要： | 以海沟金矿的大面积采空区为研究对象，将压力观测，声发射检测，位移观测等多种手段联合用于采空区围岩的稳定性监测，通过分析各种信息之间的耦合关系，得到了由压力和声发射联合表示的岩体稳定性评价的三种“判别模式”，即升压稳定模式，降压稳定模式和降压不稳定模式，实践表明，所得到的判别式利用了压力和声发射这两种普通信息之间的“耦合内涵，因而有着更好的可操作性，更宜于现场监测人员的理解和掌握。

| Abstract: | Based on analysis of relationship between different informations such as pressure measurement, acoustic emission, shift survey, 3 modes stable mode while pressure increases, stable mode while pressure decreases, unstable mode while pressure decreases－have been established to diagnose the stability of rockmass. These modes based on coupling of acoustic emission with pressure measurement possess the advantages of being operational, easier understood and mastered by operators. |
