边坡治理是露天矿山生态修复中的重要内容之一。以青海木里矿区聚乎更区为例,针对高寒矿区露天煤矿的边坡问题识别、监测和治理开展了系统研究,通过遥感、物探、钻探及地表测量等手段研究了矿区内不稳定边坡发育特征及稳定性。研究结果表明:建立了以遥感技术为核心,辅以常规的地表监测、地质调查、物探及钻探等手段的“天空地时”一体化不稳定边坡探查监测体系,确定矿区内不稳定边坡发育特征及稳定性,为矿山修复治理针对性开展边坡治理提供依据;采用高危渣山降高减载和边坡减坡治理技术,对边坡台阶进行清坡处理,消除浮石和崩塌等灾害,对渣山削坡卸载,使采坑边坡和渣山边坡达到稳定状态;并以聚乎更4号井南渣山为例,根据高密度电法探测和钻探验证,识别出了常年冻土上限和渣土层与原采坑基岩界线两个滑移面,确定后缘载荷过大是导致滑坡的主要因素,采取“后缘降高减载+边坡减坡+水系连通+综合监测”的治理方案,治理后既消除了对边坡前缘的载荷,又为后期植被复绿提供了稳定的立地条件。多期次动态监测表明边坡后缘已趋于稳定;边坡监测及治理技术在木里矿区生态修复治理中得到广泛使用,治理后的渣山边坡坡度控制均小于26°,有效消除了不稳定边坡对修复治理的影响,保障了矿山生态修复治理成效。

For elders with dementia, wandering is among the most problematic, frequent and dangerous behavior. Managing wandering behavior has become increasingly imperative due to its high prevalence, negative outcomes and burden on caregivers. We study to propose an active infrared-based method to identify wandering locomotion by monitoring rhythmical repetition of an elder’s indoor motion events. Specifically, we utilize our customized active infrared sensors to collect human indoor motions that will be converted into motion events by using hardware redundancy technique. Each motion event is a directed motion obtained via introducing temporal and dimensions into the spatial motion data. Based on the most cited spatial-temporal patterns of wandering locomotion, a spatiotemporal model is then proposed to identify wandering locomotion from an ongoing sequence of motion events. Experimental evaluation on eight individuals’ real-world motion datasets has shown that our proposed method is able to effectively identify wandering locomotion from repetitive events collected from active infrared sensors with a value over 98% for both accuracy and precision based on properly chosen parameters. Wandering in elders with dementia that follow specific spatiotemporal patterns can be reliably identified by analyzing repetitive motion events collected from active infrared sensors based on the well-known spatiotemporal patterns of wandering locomotion.
