Abstract: For ensuring safety and normal operation of the coal preparation plant′s existing systems during the process of constructing a coal silo over the belt conveyor trestle, part of the civil work of the trestle on silo construction site is removed while the section of the belt conveyor in the scope of the silo construction site is lifted up using the new steel truss, for facilitating the design and construction of the foundation of the silo. Practice shows that the use of such a design method can successfully overcome safety-related problems, shorten construction period, avoid economic loss because of no need for shutdown or interruption routine coal washing operations, curtail capital cost, and improve economic performance of coal preparation plant. The design method together with the method practically proposed for the design of shallow foundation of silos may serve as a certain reference for construction of workshops or silo by similar coal preparation plants.
