Nowadays, there are many different methods for monitoring waste dump landslides based on GPS, total station, remote sensing, UAV, Lidar, etc. However, these technologies can only periodically monitor but cannot continuously monitor in real time. In recent years, GNSS CORS technology has been applied to continuously monitor real time waste dump landslides in open-pit mines to provide immediate or nearly-instant warning of waste dump landslides, which can timely prevent and minimize damages to property and human life. In the present work, the real time monitoring system of waste dump landslides monitoring based on GNSS CORS technology was designed and built. This real time monitoring system includes (1) the GNSS CORS station based on Leica technology, (2) the monitoring stations system, (3) the data collection, transmission and processing system based on Trimble technology and the warning system. This system allows continuous monitoring in real time and provides an instant warning if the landslide occurred. Moreover, it also has the advantage of being cheap, flexible and easy to install for monitoring stations. A simulation experiment results showed that our monitoring system operates stably and continuously 24/7 with a horizontal accuracy of ±3 mm and vertical accuracy of ±5 mm.

Częste występujące ulewy mają katastrofalne skutki powodując osuwanie mas skalnych na zwałowisku. W wyniku tego następuje zniszczenie, zasypanie urządzeń, dróg dojazdowych itp. Obecnie istnieje wiele różnych metod monitorowania osuwisk na zwałowiskach w oparciu o GPS, tachimetr, teledetekcję, UAV, Lidar itp. Jednak technologie te mogą monitorować tylko okresowo, nie mogą monitorować w sposób ciągły w czasie rzeczywistym. W ostatnich latach, technologia GNSS CORS była stosowana do ciągłego monitorowania w czasie rzeczywistym osuwisk na zwałowiskach w kopalniach odkrywkowych, aby zapewnić ostrzeżenie natychmiastowe lub prawie natychmiastowe o osuwiskach, co może na czas zapobiec i zminimalizować szkody mienia i życia ludzi. W artykule, przedstawiono system monitoringu osuwisk w czasie rzeczywistym w oparciu o technologię GNSS/CORS. Ten system monitoringu w czasie rzeczywistym obejmuje (1) stację GNSS CORS opartą na technologii Leica, (2) system stacji monitorujących, (3) system zbierania, transmisji i przetwarzania danych oparty na technologii Trimble oraz system ostrzegawczy. System ten umożliwia ciągłe monitorowanie w czasie rzeczywistym i zapewnia natychmiastowe ostrzeżenie w przypadku wystąpienia osuwisk. Ponadto ma tę zaletę, że jest tani, elastyczny i łatwy w instalacji dla stacji monitorujących. Wyniki eksperymentu symulacyjnego wykazały, że nasz system monitorowania działa stabilnie i nieprzerwanie 24 godziny na dobę, 7 dni w tygodniu z dokładnością poziomą ± 3 mm i dokładnością pionową ± 5 mm.
