Method for multiple lift stacking using mobile conveyor system
Mobile conveyor modules are used for transporting aggregate over a long distance, or for transferring the aggregate to other modules, and for stacking the aggregate either linearly or radially. These modules may be used in various combinations by themselves or in combination with existing conveyor systems and bridge stackers to stack aggregate on and off multi-lift leach pads and on multi-lift dump sites. Multiple stacking methods may be used with mobile conveyor modules either separately, or at the same time, advance and retreat stacking, the stacking of a berm, or the filling in or a corridor, may be accomplished on a variety of terrain.
1. A method for multiple lift stacking of aggregate, the method comprising:
advance stacking a berm for conveyor system travel;
advance stacking an extension phase in conjunction with the berm stacking, wherein aggregate is placed outward from a supply point during the extension phase; and
advance stacking a retraction phase, wherein aggregate is placed inward toward the supply point during the retraction phase.
2. The method of claim 1 , further comprising:
retreat stacking a second lift extension phase creating a corridor;
retreat stacking a second lift retraction phase; and
stacking the corridor in conjunction with stacking the retraction phase.
3. The method of claim 2 wherein the second lift retreat stacking phase is stacked by a bridge stacker.
4. The method of claim 2 wherein the second lift corridor is stacked by a radial stacker.
5. The method of claim 1 wherein the berm is stacked by a radial stacker.
6. The method of claim 1 wherein the extension phase is stacked by a bridge stacker.
7. A method for stacking aggregate, the method comprising:
stacking one half of a site creating a portion of a corridor;
stacking the other half of the site creating another portion of the corridor; and
stacking the corridor in conjunction with stacking the other half of the site.
8. The method of claim 7 wherein the one half and other half of a site is stacked by a bridge stacker.
9. The method of claim 7 wherein the corridor is stacked by a radial stacker.
10. A method for multiple lift stacking of aggregate, the method comprising:
advance and retreat stacking an extension phase creating a corridor, wherein aggregate is placed outward from a supply point during the extension phase;
advance and retreat stacking a retraction phase, wherein aggregate is placed inward toward the supply point during the retraction phase; and
stacking the corridor.
11. The method of claim 10 further comprising stacking a berm in conjunction with the extension phase.
12. The method of claim 10 wherein the corridor is stacked in conjunction with the retraction phase.
13. The method of claim 10 further comprising repeating the steps of claim 10 on a second adjacent site.
14. The method of claim 13 further comprising repeating the steps of claim 10 on a third adjacent site.
15. The method of claim 14 further comprising repeating the steps of claim 10 as a second lift on top of the adjacent sites.
16. The method of claim 15 further comprising repeating the steps of claim 10 as a third lift.
17. The method of claim 15 further comprising the step of building an equipment corridor to the top of the second lift.
18. The method of claim 10 wherein a portion of a first lift and a portion of a second lift are formed concurrently during the extension phase.
19. The method of claim 10 wherein a portion of a first lift and a portion of a second lift are formed concurrently during the retraction phase.
