In this paper, we focus speci cally on the truck and loader equipment selection problem for surface mines.
Cross Section of Coal Seams Extracted Using Surface Mining Methods Another consideration that generally governs the selection of the underground or surface mining methods to extract a given coal seam and reserve is the quality of the coal seam. Very few coal seams in Appalachia and West ia are comprised entirely of coal.

Analysis of surface coal mining using computer simulation
Abstract. The objectives of this study were to: develop a comprehensive surface coal mine simulation model that is easy and inexpensive to apply for the benefit of the smaller to mediumsize coal mine operators of hilly topographic regions formulate a comprehensive approach to equipment quantity and size selection and examine the current reclamation practices of these regions with a view to
Surface Mining Techniques Surface mining of coal is characterized by the use of large, capitalintensive and efficient mining equipment. First, the overlying soil and rock layers (overburden) are removed. The coal is then fractured with explosives or machines, and loaded onto vehicles for haulage from the mine site. Finally,
those involved with surface mine haulage road design with a complete manual of recommended practices that, if implemented, will promote safer, more efficient haulage routes. INTRODUCTION During the past 30 years, surface mine haulage equipment has developed from trucks capable of
When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited. This equipment can include the following: Draglines which

Underground v.s. Surface Coal Mines: Is Deep Drilling
Although both methods have their benefits and drawbacks, underground drilling may just be the cost worthy selection for you Mining for coal depends on many variables. The geology and environmental aspects play a vital role, but depth and quality of the seam is what brings home the bacon. Depending on where the seam (profitable bed of coal) is loed, extracting this black gold can require a
