Abstract

Slope stability is a persistent geotechnical challenge in the mining industry, necessitating meticulous planning in the design of mine slopes. Even after a slope design is confirmed as safe, continuous monitoring is essential, as initially stable slopes can become unstable due to slope movements, ultimately leading to failure. Currently, one of the most advanced and accurate slope monitoring methods is ground radar technology, developed by GroundProbe, which offers precision of up to 0.04 mm using the SSR-XT system. PT Satria Bahana Sarana utilizes the SSRXT to monitor slopes in a coal mining front, as the area has experienced landslides in the past. This study aims to identify the types of slope deformation occurring in the area, predict the timing of potential landslides, and provide geotechnical alarm recommendations for slope stability. The monitoring data obtained from the SSR includes deformation, coherence, velocity, and pixel. This data was processed using Microsoft Excel to generate monthly classifications of slope deformation, praphs and tables forecasting landslide timing, and Upper Control Limit (UCL) and Critical Value results for the slope. At pixel coordinates x = 36, y = 17, the slope exhibited three deformation patterns: linear, progressive, and regressive, ordered from most to least frequent. Among the three Velocity Change Point (VCP) models applied, VCP 360 provided the closest estimate to the actual landslide occurrence. The recommended alarm threshold (UCL) was set at 5.69 mm/hour, while the Critical Value for slope failure was determined to be 22.96 mm/hour.
