Student Involvement

One graduate student will work full time on this project. The student will be a Ph.D. candidate from department of Mining Engineering and his primary task will be conducting of laboratory and field testing of the instrument.


Project Objectives

The objective of this research project is to conduct laboratory and field evaluation of HRTMM which can remotely measure ground deformations with sub-millimeter accuracy. The monitor will be based on unique technology for the measurement of positional changes in targets located at any distance which is being developed at Missouri S&T (formerly the University of Missouri-Rolla). This system has the potential to yield extremely high accuracy for the detection and monitoring of positional changes (as small as 0.125mm with the current laboratory implementation) presented by many types of targets located close by or very distant from the monitor.


Project Abstract

The investigators seek funds to evaluate this system at underground tunnels to asses the impact of elements such as dust, vibration and lighting on the performance of HRTMM.


Anticipated Benefits

The ground failure in mining and civil engineering structures not only impacts the safety of people but also has a direct economic impact on the companies through the loss of equipment, loss of valuable mineral ore and cleanup costs. The ability of this system to remotely measure ground movement with sub-millimeter accuracy will allow for monitoring the ground movement in areas of high traffic or which are inaccessible for installation of traditional ground movement sensing devices. The high resolution ground movement monitoring system will allow for a better understanding of ground failure mechanisms and provide an advance sensing tool for geotechnical monitoring. Other applications where this system can be used include r emote measurement of movement and/or deformational changes occurring in numerous types of targets, for example, open pit mines, road embankments, underground tunnels and mine excavations, nuclear repositories, buildings, bridges, satellites, water level, deformation of tanks containing pressurized liquefied gas, undersea structures, volcanoes, etc.


Modal Orientation

Monitoring and measurement of ground movement along road embankments, underground tunnels, monitoring of deformations on structures such as bridges or buildings.
