Uav-Based Geotechnical Modeling And Mapping Of An Inaccessible Underground Site, Elizabeth Anne Russell Apr 2018

Uav-Based Geotechnical Modeling And Mapping Of An Inaccessible Underground Site, Elizabeth Anne Russell

Graduate Theses & Non-Theses

Digital photogrammetry is becoming a more common method used for mapping geological and structural rock mass features in underground mining. The issue of capturing geological and structural data in inaccessible, unsupported areas of mines remains even when utilizing terrestrial photogrammetric methods; thus, geotechnical models of mines are left with incomplete datasets. Large unsupported underground voids, like stopes, have the potential to cause major failures, but by filling in the geotechnical data gaps in inaccessible areas, potential failures can be predicted through kinematic analysis of the area’s mapped discontinuities. Implementation of Unmanned Aerial Vehicles (UAVs) in underground mines and recent ...


Evaluation Of A Three-Dimensional Model For Slurry Storage Facilities, Robert Miller Jan 2012

Evaluation Of A Three-Dimensional Model For Slurry Storage Facilities, Robert Miller

Civil Engineering Graduate Theses & Dissertations

In many mining operations large quantities of tailings in a slurry form are produced; disposing of these tailings frequently requires construction of tailings impoundment facilities (ponds). A pseudo three-dimensional model has been developed to simulate the deposition and consolidation of tailings for a given site geometry. This three dimensional model or tailings management tool (TMT) gives the tailings surface height vs. time, void ratio distributions vs. time and average dry unit weight vs. time - which aids in the design of the facilities. This thesis evaluates the model and serves as a user manual for the model. Additional features that have ...

Visualizing And Modeling Interior Spaces Of Dangerous Structures Using Lidar, Norbert H. Maerz, T. K. Assebaum, Dustin J. Williams, K. Shea, Yongjian Xi, Xiaoling Li, Ye Duan

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

LIght Detection and Ranging (LIDAR) scanning can be used to safely and remotely provide intelligence on the interior of dangerous structures for use by first responders that need to enter these structures. By scanning into structures through windows and other openings or moving the LIDAR scanning into the structure, in both cases carried by a remote controlled robotic crawler, the presence of dangerous items or personnel can be confi rmed or denied. Entry and egress pathways can be determined in advance, and potential hiding/ambush locations identifi ed. This paper describes an integrated system of a robotic crawler and LIDAR ...
