Embodiment Construction

[0029] In order to further describe the present invention, a new tailings dry stacking process method of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0030] Depend on figure 1 Shown is a schematic diagram of the three-dimensional structure of the tailings dry stacking dam stockpiled by a new method of the tailings dry stacking process of the present invention and combined with figure 2 , image 3 It can be seen that a new method of tailings dry stacking process of the present invention determines the dry stockpile site 1 according to the requirements of the overall mine planning, and determines the engineering geology of the dry stockpile site 1 by investigating the tailings dry stockpile site 1 and hydrogeological conditions, and treat the dry stockyard site 1 to increase its seepage capacity to ensure that water can seep out smoothly in the later construction; and then according to the conc...

Abstract

The invention discloses a novel method of tailing dry pile process. The technical scheme is used for achieving dry pile field survey, tailing character analysis, treatment and analysis of field foundations, analysis of ground water transfusion fields, confirmation of dry pile field parameters and selection of soil engineering woven bag specification. Tailing pulp is injected in soil engineering woven bags by using tailings produced by a dressing plant, water in the tailing pulp flows out through the soil engineering woven bags (3), and coarse grain tailings are left in the bags and finally completely filling the bags. The soil engineering woven bags (3) filled with the tailings are piled from bottom to top according to staggered layers, a finally stockpiling tailing dry pile dam body (6) is a prismatoid structure with a narrow upper portion and a wide lower portion, a discharge and seepage pipeline (4) is arranged in the tailing dry pile dam body, and a slope face earthing protective layer (5) is arranged on the surface of the tailing dry pile dam body (6). The new method of the tailing dry pile process can not only solve the problem caused by the fact that tailing pond terrains for construction is lack nearby a mine, but also reduces long distance delivery cost of the tailings, guarantees normal production of the mine, and quickens building speed of the mine.

Description

technical field [0001] The invention relates to a tailings stockpiling method, in particular to a tailings dry stacking process, which is widely suitable for tailings dry stacking in areas lacking conditions for building dams (tailings ponds), and is especially suitable for Projects where there is no ideal storage site or the storage site is too far away from the concentrator and other factors cannot build tailings storage. Background technique [0002] Tailings pond refers to the place where dams are built to intercept valleys or enclosures to store metal and non-metal mines for ore sorting and then remove tailings. It is a necessary facility to maintain normal mine production and is the largest environmental protection project for mining companies. project. It can prevent tailings from being discharged randomly to rivers, rivers, lakes, seas, deserts and grasslands. [0003] At present, the types of tailings ponds include valley-type tailings ponds, mountain-side tailing...
