Abstract. The paper presents a method for modelling and optimization of mining operations in coal mines (CPRG). The method aim is to support designers in evaluating alternatives of the deposit cut and order of operations in the new parts of the seams or at the new levels taking into account the equipment selection aspect.


(II) Design of an underground coal mine based on an actual coal reserve. This course shall utilize all previous course material in the actual design of an underground coal mine. Ventilation, materials handling, electrical transmission and distribution, fluid mechanics, equipment selection and application, mine plant design.

¤ You can select your equipment – simple process balancing. One mine operated shuttle cars without hungry boards in a 2.6m seam because coal brushed off the car under the round ventilation tubes in about 10m of the 240m pillar sequence, and someone didn't like flat tubes. As a result the cars ran to the boot about 10% more often.


In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata.Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities for such …


Equipment Selection for Surface Mining: A Review. productivity. In surface mining applications, the ESP addresses the selection of equipment to extract and haul mined material, including both waste and ore, over the lifetime of the mining pit. In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.


Underground soft-rock mining is a group of underground mining techniques used to extract coal, oil shale, potash, and other minerals or geological materials from sedimentary ("soft") rocks. Because deposits in sedimentary rocks are commonly layered and relatively less hard, the mining methods used differ from those used to mine deposits in igneous or metamorphic …

The vast majority of underground coal mines in the United States are relatively small operations. Of the 1,345 U.S. underground coal mines in operation durhg 1992, about one-half (638) employed 20 or fewer people and about one-third (454) employed between 20 and 50 people. The median number of employees was 22. Mines of fewer


The Mining Method selection problem focuses on choosing the correct excavation method for the given mining conditions. Generally, this research is based on anecdotal methods, where a feasible solution is sought, rather than an optimal solution. Much of the literature on mining method selection does not discuss equipment selection modelling in
