摘要:
随着海州露天矿的闭坑,岩体结构越来越弱化,围岩的支承能力越来越小,露天矿边坡处于不稳定状态,具有发生大规模滑坡的潜在危险。根据海州露天矿工程地质条件,边坡形态,稳定状态及监测目的,研发海州露天矿边坡预应力锚索远程监测系统。系统应用GPRS远距离无线传输技术远程主动监测边坡岩体内部应力变化来获取岩体变形特征和滑移信息,实现边坡锚索应力全天候连续自动监测,其采用太阳能进行供电,适用于边坡中、长期监测。通过对海州露天矿边坡监测与边坡稳定性分析的现场应用实践证明,该系统可以对边坡稳态进行实时监测,对边坡滑坡灾害防治具有重要意义。
Abstract:
With the closure of Haizhou open-pit mine, the rock mass structure is weakening and the supporting force of surrounding rock becoming smaller, the slope of Haizhou open-pit mine is unstable and has potential risks for large scale landslides. Based on the engineering geological condition, the slope shape, the steady-state and monitoring pur- pose of Haizhou open-pit mine, research and develop the slope prestressed anchor cable remote monitoring system in Liaoning Haizhou open-pit mine. The GPRS long range wireless transmission technology was used to remote initiative monitoring rock stress of slope for obtaining the characteristics of rock deformation and slip information, It can monitor the slope anchor cable stress all-weather and it is suitable for medium-and long-term slope monitoring as it power sup- plied by solar energy. According to the field application of the slope monitoring and the slope stability analysis in Haizhou open-pit mine, the system was proved to monitoring the slope stability in real time. It has important signifi- cance to control the slope landslide.
