... ABSTRACT: Rockfall along mountainous roadways poses a hazard to transportation infrastructure, commercial traffic, and the public. Lidar scanning and photogrammetry are powerful tools to create high-resolution point cloud models of rock slopes and quantify change, facilitating rockfall volume...

... ABSTRACT: Rockfalls are a source of danger for infrastructure near rock slopes containing potentially unstable blocks. Rockfalls can cause property damage, road blockages, and harm to people. Literature studies that monitor rock slopes have helped to demonstrate connections between rockfalls...

... ABSTRACT: The challenge of rockfall and its associated risks has been haunting the mining industry for quite some time. It has been a significant cause of fatalities, serious injuries, and financial losses. Taking advantage of recent technological developments, novel methods of studying...

... ABSTRACT: Rockfall along roads can cause significant hazards to human health and infrastructure or interrupt transportation. A section of rock slope on Interstate 70 west, west of Idaho Springs, has been monitored at a daily frequency since March 2018 using a 5-camera photogrammetric system...

... granite at the Pinto Valley Mine in Arizona expressed warning signs such as rockfall, talus/debris retained on lower benches, tension cracks and displacements on the slope stability radar (SSR) during production adjacent to the slope. Detailed inspections, monitoring and mitigation were immediately...

... ABSTRACT: Increasing rockfall activities in alpine areas have been observed under the global climate change circumstance. One widely accepted explanation of the alpine rockfall is that the warming and thawing of ice-rich bedrock permafrost decreases effective shear strength and destabilizes...

... ABSTRACT: The standard methodology for through-time rockfall analysis from slope point clouds consists of computing changes between lidar scans, followed by grouping areas of significant change using unsupervised clustering (e.g., DBSCAN). Clusters found are indicative of a potential rockfall...

... ABSTRACT: Rockfalls pose severe hazards to miners and infrastructure in open pit mines, and rockfall barrier systems are an increasingly common method for mitigating this hazard. Extensive testing to understand rockfall kinetics and barrier efficacy has been performed in controlled settings...

... ABSTRACT: Rockfalls are naturally occurring geohazards that are frequently associated with steep or vertical slopes. Falling rocks have the potential to disrupt transportation systems, including highway and railway passages. A common trigger known to influence the frequency and severity...

... ABSTRACT: Rockfalls pose a critical risk to the mining industry. In collaboration with NIOSH and industry partners, the Geotechnical Center of Excellence (GCE) has previously shown that thermal video can effectively observe rockfall events. Currently, work is underway to automate the detection...

... ABSTRACT: Rockfall events are one of the most difficult geotechnical conditions to predict and control in a mining operation. This study is focused on the Peña Colorada open pit (Colima, Mexico), where a series of rockfalls occurred on the main slope during the period of Hurricane Lidia...

... ABSTRACT: Under a NIOSH research grant, the Geotechnical Center of Excellence (GCE) evaluated the capability and limitations of thermal cameras to detect rockfall events and the conditions that can lead to rockfall. This two-year study tested four different thermal imaging cameras...

... by the Colorado Department of Transportation (CDOT), as its susceptibility for rockfall and proximity to the roadway make it a potential threat to the operation of this stretch of highway. A goal of rockfall monitoring at Floyd Hill is to further understand rockfall activity and its relationship with common...

... ABSTRACT: In order to generate a full-scale, real world data set for calibration purposes for the rockfall simulation program RAMMS::ROCKFALL, we conducted extensive single block induced rockfall experiments with blocks of 200/800/2670 kg (~440/1760/5890 lb). With a fully four-dimensional...

... ABSTRACT: Rockfalls present a major safety threat in open-pit mining operations and transportation corridors. The sudden onset of rockfall events makes it difficult, if not almost impossible, for conventional monitoring methods to provide adequate pre-warning, resulting in a challenge...
