Embodiment 1

[0081] Such as figure 2 As shown, when the mine is excavated by trucks, the layered dam construction method is implemented, the tailings dam is divided into several layers in the height direction, and the tailings dams are piled up layer by layer by automobiles. The waste rocks are dumped directly on the ground to form a soil pile, and the soil pile is flattened by a bulldozer to form the first layer 4 of the tailings dam body, and then a fully loaded vehicle is used to roll back and forth on the first layer to compress the first layer. Leveling and compacting, then continue to dump waste rocks on the first layer to build the second layer 5, set a tailings discharge pipeline platform 6 every few layers, and form tailings dam 1 repeatedly. After formation, the dump site 2 develops toward the outside of the tailings dam.

Embodiment 2

[0083] Such as image 3 As shown, when the mine discharge is carried out by automobile, the dam is constructed in strips, and the tailings dam is divided into several strips in the width direction, which are piled up one by one by the automobile. A tailings discharge pipeline interval height is set higher than the previous tailings dam, and a tailings discharge pipeline platform 6 is set between the two tailings dams. First, the waste rocks are directly dumped by the car on the spot to form a mound, and the bulldozer will The soil mound is flattened to form the first layer 4 of the tailings dam body, and then a fully loaded vehicle is used to roll back and forth on the first layer to flatten and compact the first layer, and then continue on the first layer Turn over waste rocks and build the second layer 5, and go round and round to form the first tailings dam 8, and then build the second tailings dam 7 toward the outside of the tailings pond by the above method, and gradually...

Embodiment 3

[0108] Such as Figure 4 As shown, when the mine discharge method adopts the railway discharge method, the tailings dam is directly piled up by using the railway discharge electric shovel pile or inverted pile. First utilize electric shovel or bulldozer to form the initial embankment 9 of railway discharge, lay railway on initial embankment 9, utilize electric shovel to form initial stage dam 10 by piling up or inversion mode, lay railway on initial stage dam 10 after, utilize electric shovel to press The platform 11 is formed by stacking or inverting the soil toward the downstream of the tailings pond, and the second tailings dam 12 is formed on the platform in the direction of the downstream of the tailings pond by using an electric shovel. A tailings discharge pipeline platform 6 is set between the first tailings dams, and then a railway is laid on the second tailings dam 12, and the soil is flatly discharged to the downstream of the tailings pond to form a platform 13. The...

Abstract

The invention relates to a method for building a tailings dam, in particular to a method for building a tailings dam through adoption of mine dumping. The method comprises the following steps that: a mine dumping yard and a tailings dam of a concentrating mill are combined; the mine dumping is adopted for directly building the tailings dam; a layered damming method or a strip damming method is implemented; after the tailings dam is formed, the inner side of the tailings dam is a tailings warehouse; and the outer side is a dumping yard. As mine dumping technology and damming technology of the tailings dam of the concentrating mill are combined, the method can greatly reduce the area occupation of the dumping yard, enlarge the utilization coefficient of the tailings warehouse and overcome the disadvantages of the prior damming construction method of the tailings warehouse and the difficult problems of sand lifting of tailings sand and the like; and meanwhile, after a mine stops production, under the condition that the mine dumping cannot be used for building the tailings dam, the concentrating mill can also utilize waste stone of the dumping yard to continue building the tailings dam. The process is suitable for the tailings warehouses of a valley type, mountain-surrounding type, flat type, cut-off river type and other types, is also suitable for building the tailings dam of theconcentrating mill of other industries, is also suitable for newly building the tailings dam of the concentrating mill and is also suitable for building the tailings dam of the concentrating mill in course of production.

Description

technical field [0001] The invention relates to a method for stacking a tailings dam, in particular to a method for stacking a tailings dam by using mine discharge. Background technique [0002] There are two kinds of wastes in mine production, one is open-pit mining stripping, and the other is dressing plant tailings. The former needs to build a dump site to discharge waste rocks; the latter must be properly disposed of because it contains useful components that cannot be recycled at the current technical level or contains a large amount of harmful substances. The tailings are usually stored in a reliable way and are not allowed to be lost. Tailings are usually stored by building embankments to form a tailings storage, and the tailings are discharged into the storage for sedimentation and storage. At present, the stripped materials from domestic mines and the tailings from ore processing plants are discharged separately. Mine dumps and tailings ponds both occupy relativel...
