基于GPS技术的露天煤矿边坡变形规律及趋势分析

Deformation Law and Trend Analysis of Open-pit Coal Mine Slope Based on GPS Technology

以我国内蒙古地区某露天煤矿C标变形区为研究对象,为得到该区域边坡破坏模式及变形规律以便有针对性的对其采取防治措施,首先了解该地区近年来边坡变形及滑坡情况,并在该变形区不同位置布置监测点形成监测线,对相应区域进行GPS监测。通过对各监测线、监测点变形数据进行统计分析,圈定了该露天矿边坡的变形区域,对该区域边坡破坏模式和变形规律进行研究,并对该区域变形趋势进行了预测,得出该区域边坡变形速率与采矿活动及当地季节气候有关。

Taking the C-shaped deformation zone of an open-pit coal mine in Inner Mongolia as the research object,to obtain the slope failure mode and deformation law of the area so as to take targeted prevention and control measures,firstly,the situation of slope deformation and landslide in this area in recent years was understood,and monitoring points were arranged in different positions of this deformation area to form monitoring lines,and GPS monitoring was carried out in the corresponding area.Through the statistical analysis of the deformation data of each monitoring line and monitoring point,the deformation area of the open-pit mine slope is delineated,the failure mode and deformation law of the slope are studied,and the deformation trend of the area is predicted.The rate of slope deformation in this area is related to mining activities and local seasonal climate.
