基于混沌理论的矿山边坡岩体变形规律与安全预警系统
Deformation laws of rock mass and safe alarm system of mine slope based on chaotic theory
摘要
Abstract
Through establishing the safety monitoring system in an open-pit slope,and using the chaos theory of phase space reconstruction,the deformation laws of rock mass in open-pit slope were revealed.Based on the reconstructed phase space,a deforming prediction model of chaotic neural network in slope rock mass was established,and thus the high accuracy prediction of slope deformation was realized.Meanwhile,analyzing the characteristics of open-pit mining,an early safe waming system of slope deformation was set up.The results show that in open-pit mining process,influenced by jointed,mining intensity,underground water,surface rainfall and other factors,the deformation of slope rock mass is dominated by its intrinsic deterministic dynamics mechanism,and has shown the features of chaos as a result of the engineering inherent impacts.The safe warning system can not only predict the slope rock mass deformation and the security zone,but also reflects the rationality of open-pit mining intensity,which provides technical support for regulating mine production and ensuring production safety.关键词
