摘要
为了保证山西平朔安太堡露天矿不采区露天与井工的同时安全开采,对安太堡不采区边坡进行了地表位移和沉陷监测。在第一期和第二期边坡变形监测中分别采用GPS-RTK和快速静态技术,建立了能反映变形规律且满足一定精度要求的监测系统。第一期监测表明,在采用课题组设计的回采方案下,B900综放工作面的回采不会导致安太堡东帮边坡出现整体滑坡;通过第二期监测,准确及时地预警到2006年12月10日凌晨发生的一个中型滑坡(800 km3)。实践表明这两种GPS测量技术都可以满足于露天矿边坡变形监测,具体采用何种监测方法,视项目对精度的要求、项目所在地的地形情况、工作人员的数量、流动站和参考站的距离等而定。
In order to ensure the safety production both the reserved area and underground mine of Pingshuo Antaibao Surface Mine,the monitoring and measurements on the surface ground displacement and subsidence were conducted for the slope of the reserved area in Antiabao Surface Mine.The first phase and second phase monitoring and measurements on the slope deformation were conducted with GPS-RTK and rapid static technology individually.A monitoring and measurement system was established with a certain accuracy and a...
