摘要
为促进冲击地压监测预警水平的提高和监测预警新技术的推广,阐述了6种冲击地压监测预警技术分类方法及相应分类结果,探讨了冲击地压监测预警在监测参量、预警阈值、测点布置、数据分析等4个方面存在的困难,指出了冲击地压监测预警在监测范围、监测参数、监测方式、预警参量等4个方面的技术要求,分析了震动场、应力场联合监测技术和"全频广域"震动监测技术,最后介绍了"全频广域"震动监测技术应用案例。结果表明,震动场、应力场联合监测技术和"全频广域"震动监测技术在监测范围、监测参数、监测方式和预警参量等方面能够满足冲击地压监测预警技术要求,具有广阔的应用前景。
In order to promote the monitoring and early warning level improvement and the new technology promoting of the monitoring and early warning technology for the mine strata pressure bump,the paper stated the classification method and relevant classification results of the six pressure bump monitoring and early warning technologies,discussed problems existed in the monitoring parameters,early warning threshold value,monitoring point layout and data analysis and pointed out the technical requirements in the monitoring scope,monitoring parameters,monitoring method and early warning parameters of the mine strata pressure bump. The paper had an analysis on the combined monitoring technology of the seismic filed and stress field and the monitoring technology of full frequency wide range seismic. Finally,the paper introduced the application cases of the full frequency wide range seismic monitoring technology. The results showed that the combined monitoring technology of the seismic field and the stress field and the monitoring technology of full frequency wide range seismic could meet the monitoring and early warning technology requirement of the mine strata pressure bump on the monitoring range,monitoring parameters,monitoring method and early warning parameters and would have a wide application prospect.
