A system and method for building a permanent heap leaching site using a large self-moving bridge-type distributing machine

Abstract

The invention discloses a system and method for stacking or dumping waste ore through a large self-moving bridge type distributing machine. The system comprises main devices, including a breaking device, a fixed type rubber belt conveyor, a fixed type rubber belt conveyor provided with a dumper, a lightweight rubber belt conveyor belt, a travelling type rubber belt conveyor and a self-moving bridge type distributor which are sequentially arranged. The method is characterized in that the waste ore is broken and then sequentially conveyed through the rubber belt conveyors and the dumper; the self-moving bridge type distributor is arranged at the tail end of the system and can freely move in a dump leaching site or a waste ore site to arrange the waste ore; after the one layer is arranged, the self-moving bridge type distributor can independently build to raise to an upper channel so as to automatically finish layer rising. The system for stacking or dumping the waste ore in the dump leaching site has the advantages that the permeability of the ore on the top part of a dump leaching ore stack is influenced a little while stacking or dumping the waste ore; the system reliability is high; the area used is small; the energy can be saved, and the environment can be protected; the transportation capacity is high, and the operation cost is low.

Description

technical field [0001] The invention relates to a large-scale storage yard mechanical stacking system and a method, in particular to a system and a method for using a large-scale self-moving bridge-type distributing machine for permanent heap leaching site stacking. Background technique [0002] Existing discharge equipment for large storage yards and waste rock yards includes: soil dumpers, radial distribution machines, and bulldozers. When the earth-moving machine discharges soil, if there is no discharge condition due to terrain restrictions, it is limited by the arm length of the earth-moving machine. In case of large-scale (greater than 100,000 t / d) material handling capacity, the number of equipment relocations required is relatively large. Many; when the radial distribution machine builds a heap, the system consists of a large number of equipment and many links, and the reliability is not high. The pile needs dump trucks to cooperate with the transportation of ore, a...
