Belmont Quarry - Analysis of a shallow failure in ...

In May 2016, we flew a UAV (unmanned aerial vehicle, or drone) over part of Belmont Quarry, Lower Hutt, to record detailed photographs of localised bench failures. This was to help us develop a work flow that would start with the drone photography and conclude with back analysis of the slope failure using our 3D slope analysis

MINE WASTE FAILURE: AN ANALYSIS OF EMPIRICAL

2021-1-28  coal dump failures in the Canadian Rocky Mountains that occurred in the previous 25 years. Their failure mechanisms and modes were analyzed and classified; the cases were modeled, and empirical models were created in order to provide more tools to estimate the risk of mine waste failures.

Forecasting the time of failure of landslides at slope ...

2019-6-1  1. Introduction. Estimating the risk that is represented by landslides on a global scale is difficult. For instance, damage from landslides is usually attributed to the events that triggered them (as with earthquakes), and small-scale failures are often under-reported (Petley et al., 2005a).The true number of fatalities may be slightly underestimated when victims die of landslide-derived ...
