| 摘 要： | 基于岩体破裂过程中的岩体声发射事件率和能率等测试参数,研究评价地下采场岩体稳定性的声发射相对强弱量化指标,以更有效地进行围岩稳定性评价.岩体声发射相对强弱指标可消除声发射测试参数受工程布置和地质构造等环境因素的影响,综合考虑事件率及其变化率和相对强弱指标,可以更准确地预测采场围岩的稳定性.利用声发射相对强弱指标评价岩体稳定性,结果与实际情况具有较好的一致性.

| Abstract: | The relative strength-weakness characteristic of the acoustic emission parameters for rockmass stability evaluating criterion is investigated in order for effectively evaluating based on the testing results of time sequence of acoustic emission parameters. The effect of the environmental factors on geological structure or the dimensions and location of mined-out areas can be eliminated by use of the evaluating criterion of relative strength-weakness characteristic, and the rockmass stability can be more correctly predicted in stope stability monitoring by comprehensively using the time sequence and the relative strength-weakness characteristic. The evaluating result is well consonant with the practical situation. |
