following blasting, the fragmented ore is loaded on a mining truck and hauled to the crusher for primary crushing. many mines employ two to three stages of crushing. some mines have the primary crusher located in the mine, using conveyors to transport the crushed ore to the secondary and tertiary crushers or directly to the mills.
stock and provide spare parts close to the mining operation. good geotechnical information is essential to crushing plant siting and design. installing a primary crushing plant on solid rock reduces the cost of concrete and structural steel. life of mineexpansion plans the life of the mine is a key element in the design of any crushing plant.
abutment In coal mining, the weight of the rocks above a narrow roadway is transferred to the solid coal along the sides, which act as abutments of the arch of strata spanning the roadway; and the weight of the rocks over a longwall face is transferred to the front abutment, that is, the solid coal ahead of the face and the back abutment, that is, the settled packs behind the face.
