金属矿山岩层能量释放规律及相应的安全预警系统

Energy Release Law of Rock Strata in Metal Mines and Corresponding Safety Early Warning System

基于对岩层变形进行长期观测的基础上,提出岩层能量释放的分析方法,通过对地层能量释放时间序列数据进行相空间重构,揭示了岩层能量释放点之间距离的演化规律,建立了岩层能量释放预测模型。结果表明,岩层能量释放具有混沌特征,充分显示其内在规律,建立岩层稳定预警系统为安全开采提供技术保障。

Based on the long-term observation of the deformation of rock strata,the analysis method of the energy release of rock strata is proposed.Through the phase space reconstruction of the time series data of the energy release of rock strata,the evolution law of the distance between the energy release points of rock strata is revealed,and the prediction model of the energy release of rock strata is established.The results show that the energy release of rock strata has chaotic characteristics,which fully shows its internal law.The establishment of rock strata stability early warning system provides technical guarantee for safe mining.
