摘要:
露天开采矿山多为大型矿山，采矿活动导致矿区原始地形地貌破坏，且占用了大量的土地资源，有可能诱发地质灾害。以内蒙古八岔沟矿露天采场为例，通过对边坡区域工程地质、水文地质条件分析,确定边坡存在的主要滑坡模式为平面破坏、圆弧形破坏、楔形体破坏、倾倒破坏、崩塌破坏，并提出采用“坡面散体及碎浮石清理挖除＋被动网拆除＋预应力锚索＋锚杆＋框架梁＋喷锚网＋排水孔＋帷幕注浆”的技术方案实施治理。实践证明：该治理技术具有超前性、主动性，做到了投入少、效果好，大大节省了基建成本，为矿山的安全生产提供了技术支撑，保障了平台工作人员及设备车辆的安全，保证了露天开采工程的顺利开展。

Abstract:
Open-pit mining is mostly carried out in large-scale mines,which leads to the destruction of the original terrains and landscapes in the mining area and occupies a large quantity of land resources,which may trigger geologi-cal disasters.Taking the Bachagou Mine in Inner Mongolia as an example,through the analysis of engineering geology and hydrogeological conditions in the slope area,the main landslide modes of the slope are determined to be planar failure,arc-shaped failure,wedge-shaped failure,dumping failure,and collapse failure.A technical scheme of slope unconsolidated body and debris removal,passive mesh demolition,prestressed bolt,bolt,frame beam,shotcrete-bolt-mesh,drainage holes,and curtain grouting is proposed for implementation and treatment.Practice has proved that this treatment technology is advanced and proactive,with small investment and good results,greatly saving infrastructure costs,providing technical support for mine safety production,ensuring the safety of platform workers and vehicle equipment,and ensuring the smooth operation of open-pit mining projects.
