Comparative Evaluation of Fogging Phenomenon in the Ramp of Three Mines in Finland
In Finland fogging in mine ramps is a common problem. Fog forms when warm and humid exhaust air moves upwards the ramp, where the skin temperature of surrounding wallrock decreases to about 10°C. Changes in fog thickness and lengths of fog-filled parts of the ramp depend at least on climatic conditions outside, diesel equipment usage in the mine, and the length of working sequence at a time. In...
متن کاملFog Mesh Studies for Fog Removal
Field tests concerning a fog mesh method for fog removal are discussed. The first tests were performed at the Pyhäsalmi Mine, Finland. As this study gave promising results, further studies were completed at the Orivesi Mine. The results of these most recent field tests are presented and the two studies are compared. The Orivesi test set consisted of four materials. These included air filter fab...
متن کاملReview on Single Image Fog Removal
In this paper, reported algorithms for fog removal are reviewed. Fog reduces the visibility of scene and thus performance of various computer vision algorithms which use feature information. Formation of the fog is the function of the depth. Estimation of depth information is under constraints problem if single image is available. Hence, removal of fog requires assumptions or prior information....
متن کاملCost Optimisation for Underground Mining Networks
In this paper we consider the problem of optimising the construction and haulage costs of underground mining networks. We focus on a model of underground mine networks consisting of ramps in which each ramp has a bounded maximum gradient. The cost depends on the lengths of the ramps, the tonnages hauled through them and their gradients. We model such an underground mine network as an edgeweight...
متن کاملApplication of mine waste for wastewater treatment: Efficient organic pollutant removal
In this research, a high porous silicate mining waste that was prepared from Syah Kamar Polymetal Porphyry mine in order to malachite green dye (MG) removal has been applied. The characterization of this natural mineral was determined using the XRD, XRF, SEM and FT-IR analysis. The MG adsorption onto high porous activated waste was studied based on the parameters of pH, temperature, adsorbent d...
