Embodiment Construction

[0023] In order to further describe the present invention, in conjunction with the accompanying drawings, the new method of the present invention suitable for dry tailings of flat-type tailings ponds is described in more detail. The tailings pond is a flat ground type surrounded by dams.

[0024] by figure 1 The present invention is suitable for the new method of dry mining of flat tailing pond tailings. The schematic plan layout and combination figure 2 It can be seen that the new method of the present invention suitable for dry mining of tailings in flat-type tailings ponds includes the following processes and steps:

[0025] Systematic investigation of the stability of the tailings reservoir dam body, flood drainage methods, the effectiveness of the flood drainage system, the strength of the tailings beach foundation bearing capacity, and the depth of the reservoir area are carried out to provide basic data for dry tailings mining.

[0026] Use gravel to pave several temporary g...

Abstract

The invention discloses a novel method suitable for flat ground type tailings pond tailings dry type recovery. A tailings pond is surveyed, a temporary broken stone road (1) is paved with broken stone from a tailings pond dam body to a tailings pond drainage shaft (2) to serve as a temporary construction road, temporary drainage ditches are excavated in the two sides of the road through an excavating mechanical device, partitioned excavating is conducted on to-be-recovered tailings below tailings pond beach faces (1) on the two sides of the temporary broken stone road (1) through an excavator with the working radium of 8-18 m after accumulated water in the area of the pond is drained, recovery of the next region is conducted after recovery of one region is completed till tailings of all the regions of one stratum are thoroughly recovered, partitioned excavating is conducted on tailings on the two sides of a temporary broken stone road on the lower layer till tailings of the tailings pond are completely developed, then the tailings recovery work of the tailings pond is rapidly and efficiently completed on a large scale, the tailings recovery efficiency of the tailings pond is improved, recovery cost is reduced, and recovery time is saved.

Description

Technical field [0001] The invention belongs to the technical field of tailings mining, and specifically relates to a dry mining method of tailings, and is particularly suitable for flat tailings with dams built around the tailings pond with a small bearing capacity and a short construction period. Reservoir tailings mining project. Background technique [0002] With the rapid economic and technological development of our country, the development of mineral resources has increased, accompanied by the creation of a large number of tailings ponds. Considerable resources are contained in tailings, and the construction and maintenance of tailings dams are very expensive, which brings environmental, safety and economic impacts and problems to mining development. Mining tailings is of great significance for making full use of non-renewable resources. [0003] At present, in the tailings recovery of tailing ponds in our country, the main methods of tailings recovery are water mining, sh...
