This paper presents an initial investigation into using estimated reflectance, derived from raw terrestrial laser scanner intensity data, to model clay content within a potash mine. The mines of interest are located in the Prairie Evaporite Formation

The GPS has revolutionized how people, vehicles, and objects are positioned. The GPS, however, has limitations. It will only work well where a signal can be received and will not work underground, in tunnels, or even some buildings. Obtaining an accu

The energy spectral density characterization of microseismic events in two potash mines is presented. It is shown that there is little difference between the two mine characterizations, evidenced by each having an approximate 3 dB bandwidth of 38 Hz

With the increasing use of Terrestrial Laser Scanners (TLSs) to sense various environments it becomes increasingly necessary to develop automated processing techniques to deal with the large amount of data generated. To aid in the automatic processin

Estimating the location of a radiating source from recorded sensor signals requires accurate arrival time estimates. If the sensor signals have a short time duration, generating accurate arrival time estimates is a challenging task. This paper propos

Terrestrial Laser Scanners (TLS) measure distances and record angles to objects in the surrounding environment. In addition, a TLS also measures the amount of reflected light (intensity). The intensity value provided by the TLS is a function of the d

Underground soft rock mines are constantly deforming — this is a normal rock response to mining excavation. Once a mine opening has been excavated or cut, the opening begins to deform into the excavation. This rock displacement, or room closure, co

Determining the real-time position of an underground mining vehicle relative to a global map is a very important problem facing the mining industry. Unfortunately, techniques such as Global Positioning System (GPS) cannot be used in underground mines

This paper describes the problem of locating a vehicle relative to a digital map of an underground mine. The mines of interest produce potash, and they are at a depth of approximately 1000 meters, being relatively large, covering an area greater than

In this paper the problem of estimating the position of a user relative to a map of an underground mine is explored. A positioning system consisting of a set of sensors and a digital mine map is proposed and modeled using a state space representation
