【摘要】 岩体声发射技术是矿山采场地压管理的重要手段之一,本文在声发射实验的基础上,介绍了岩体声发射技术在厂坝铅锌矿的应用,即岩体分级指标结合声发射指标对采场安全等级的划分和采场稳定性声发射动态监测预报,说明岩体声发射技术在矿山地压管理可以有广泛的应用及很大的优越性,同时指出了人们对于岩体声发射技术在采场稳定性监测方面存在的一些误区,最后还指明了岩体声发射技术有待进一步研究和发展的方向。更多还原

【Abstract】 Rock mass Acoustic Emission Technology is one of the main means to control the pressure of ground of mining stopes. Based on the AE experiments, this article introduces some applications of rock mass AE technology in Changba Lead-Zinc Mine. That is, partitioning the safety grades of mining slope by means of rock mass classifying index combined AE index, and AE dynamic monitoring and forecasting stability of mining stope. It explains rock mass AE technology has wide application and great advantage in managing the ground pressure of mining stopes. Meanwhile, it points out some errors in rock mass AE technology monitoring mining stope’s stability. In the end, it points out the direction of rock mass AE technology further research and development.更多还原
