西石门铁矿排土场稳定性分析及治理措施研究

摘要

Taking the waste dump in Xishimen iron mine as engineering example, the stability of waste dump was analyzed .The subsidence of surface waste dump after excavation of lower mine body was analyzed by combining the field survey, laboratory test and numerical analysis.The influence range of dump debris flow was predicted by geo-graphic information system.According to the scene situation of waste dump, through the choice of dam body and mechanical calculation, the prevention measures of debris flow and landslide suitable for waste dump in Xishimen i-ron mine were determined.It provides an example for the stability evaluation and treatment design of similar dumps.%依托矿山排土场工程实例，分析了西石门排土场的稳定性。采用现场调查、测试试验和数值分析相结合的手段分析了下部矿体开挖后地表排土场的沉降。应用地理信息系统预测了排土场泥石流发生的影响范围。根据排土场的现场情况，通过坝体选型及力学计算，确定了适合西石门排土场的泥石流滑坡防治措施，为同类排土场的稳定性评估和治理设计提供了范例。
