A method for detecting buried mines in ground penetrating radar (GPR) data using a Hough transform approach is described. GPR is one of three sensors used in the Mine Hunter/Killer (MH/K) system for detecting buried mines. A buried mine modeled as a point scatterer in object space gives rise to a hyperbolic response in GPR measurement space. Our approach uses the Hough transform to recover the ...

Using explosive material to fragment rock masses is a common and economical method in surface mines. Nevertheless, this can lead some environmental problems the surrounding regions. Flyrock one of most dangerous effects induced by blasting which needs be estimated reduce potential risk damage. In other words, minimization flyrock sustainability surroundings environment sites. To aim, present st...

Background: In this study are submitted the radon concentration measurement results of four underground mines: Stanterg, Artana, Hajvali and Badovc, which are owned by Trepça Enterprise, Kosovo. The mines have the same geological formation and from these mines are extracted ores rich with lead, zinc, silver, and gold. The radiation exposures caused by radon and radon daughters was determ...

Search strategy is an important component of any system that uses autonomous agents to detect and neutralize mines. We describe a simple and efficient search strategy derived from research on the adaptive spatial behavior of animals. Electromagnetic sensor data are processed to obtain a discrete spatial target distribution. The target distribution is used as input for a dynamic diffusion proces...

This paper describes two robotic systems developed for acquiring accurate volumetric maps of underground mines. One system is based on a cart instrumented by laser range finders, pushed through a mine by people. Another is a remotely controlled mobile robot equipped with laser range finders. To build consistent maps of large mines with many cycles, we describe an algorithm for estimating global...

This paper deals with the issue of safety inside underground mines. The safety system designed based on wireless sensor network. The position of the different sensors inside underground mines is set by using analysis with ANSYS software. The safety system modeling in this paper is cost effective, energy saver , consistent, uninterrupted. This system performs automatic monitoring of different us...
