The Effects of Surface Mining Technology on the Economy of the Haulage Process and Mining Productivity
In general, modern mining companies all over the world have to face the same economic circumstances as any other part of the industry: considering the tough competition, production and haulage costs must be reduced permanently whereas productivity has to increase substantially in order to remain price-competitive. However, the imposed pressure also offers the chance for consideration of alternative mining concepts, the application of which can result in substantial cost savings and improvements in the quality of the mined material. As one of these alternative mining concepts, surface mining technology offers substantial improvements in productivity. It also influences aspects of haulage, such as safety and speed, in a positive way. The capability of selective mining ties in nicely with the production of small-sized crushed material, the granulometry of which allows the elimination of the primary crusher. Mine operators profit from reduced costs for the maintenance of their haulage vehicles due to reduced wear, a decreased likelihood of accidents and higher average transport speeds. Surface Miners can also be used to cut haul roads into virgin rocks and leave a clean and level surface behind, improving the quality of these created roads. Thus, it is even possible to use ordinary road trucks for transport in mines. The current paper outlines in detail the effects of the surface mining technology on mining and haulage aspects and reports on applications where substantial cost savings could be achieved due to the application of what is also referred to as simple mining process'.
