| 摘 要： | 岩体在破坏过程中，必然产生声发射现象。岩体声发射的频度、强弱及高能事件与岩体的破坏过程密切相关。根据岩体声发射的特点及其相关参数将岩体声发射检测技术应用于采场顶板安全等级划分，为采矿安全管理提供技术指导。矿山实际应用情况表明该方法是可行的。

| Abstract: | Acoustic emission occurs certainly for rock mass fracturing. The frequency, strength and energy of acoustic emission are concerned with rock mass fracturing. According to the characteristics and relevant data of the rock mass acoustic emission, the testing technology of it is used in safety classification of stope roof, which has provided safety management of mine with technical orientation. A case of one mine proved that rock mass safety classification method is useful. |
