煤层突出危险性的声学预测方法

Acoustic Prediction Method of Coal Seam Outburst Hazard

介绍了俄罗斯AК-1型声学预测系统的原理和技术性能,以及在俄罗斯有关矿区的应用情况,对预测结果进行了分析。结果表明,与标准预测方法R1指标相比,在地质构造破坏带,声学预测方法具有较高的可靠性,可以用来预测地质构造破坏带和煤层的突出危险性。

The paper describes the principle and technical performance of Model AK-1acoustic prediction system made in Russia and its application in Russian coal mining areas,and gives an analysis on the prediction results.The results indicate that the acoustic prediction method has high reliability in fracture zone of geological structures as compared with the index R 1 of standard prediction method and can be used to predict fracture zone of geological structure and the outburst hazard of coal seams.
