蒙库铁矿高陡边坡稳定性影响因素分析与安全控制措施

Safety Analysis on the Influencing Factors and Control Measures of High-steep Mine Slope Stability in Mengku Iron Mine

本文以新疆蒙库铁矿矿山高陡边坡为研究对象,对边坡稳定性的影响因素(岩性、结构面、几何特性、软弱夹层、爆破振动与冻融循环作用)进行了分析,在此基础上针对蒙库铁矿边坡工程实际提出了该高陡边坡的安全控制措施,并强调指出安全控制措施的制定应以"预防性安全控制措施为主,必要的工程加固为辅"为原则,其中预防性安全控制措施主要包括边坡巡查、监测预警、控制爆破、冻融效应阻隔等,工程加固措施主要包括柔性防护和喷锚网加固。

Taking the high-steep slope of Xinjiang Mengku Iron Mine as the research project,this paper analyzes the influencing factors of slope stability including lithology,structural plane,geometrical features,weak interlayer,blasting vibration and freeze-thaw recycle effect in order to put forward the safety control measures.In consideration of the in-situ situation of the slope,the paper points out that the determination of control measures should obey the rule that the preventive safety control ought to be given the first place to and then the reinforcement means.The preventive measures generally include slope inspection,monitoring and early warning,control blasting and freeze-thaw effect obstruction.
