露天边坡治理方案研究及优化

Study and optimization of slope treatment scheme for open pit east side

以曼家寨矿区东帮为背景,通过分析矿区边坡主要影响因素,结合现有边坡治理技术措施及效果,采用削坡减载、地表截排水、边坡护坡等措施,提出减小爆破对保留岩体伤害、最大限度保留边坡岩体的原始强度等措施。优化后的措施对改善边坡性质有着良好的工程效果。

Taking the east side of Manjiazhai mining area as the background,through analyzing the main influencing factors of the slope in the mining area,combining with the existing technical measures and effects of slope treatment,the measures such as slope load reduction,surface interception and drainage,slope protection and so on are adopted.Measures such as reducing damage to reserved rock mass by blasting and preserving the original strength of slope rock mass to the maximum extent are put forward.The optimized measures have good engineering effect on the improvement of slope properties.
