Embodiment Construction
[0020] In order to better describe the present invention, a method of using waste rocks to reinforce the tailings dry stockpile of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0021] Depend on figure 1 Shown is a schematic diagram of the dry stockpile plane layout of a method of utilizing waste rocks to reinforce the tailings dry stockpile of the present invention and combined with figure 2 It can be seen that the present invention uses waste rocks to reinforce the tailings dry stockpile method. A drainage pipe 8 is arranged at the bottom of the tailings dry stockpile 1, and a drainage prism is provided at the bottom of the outer side of the tailings dry stockpile dam body 2. 7. Build a waste rock dam 3 inside the tailings dry stockyard dam body 2 that has been built, build a waste rock intermediate dam 4 in the waste rock dam 3, and build two waste rock intermediate dams 4 on both sides. In the space betwe...

The invention discloses a method for strengthening a dry tailing storage yard by utilizing barren rocks. A barren rock dam (3) is built at the inner periphery of a built dry tailing storage yard dam body (2); a barren rock middle partition dam (4) is built in the barren rock dam (3); at least two middle partition branch dams (4') are built at the two sides of the barren rock middle partition dam (4) respectively; a barren rock pile (5) is piled up in a gap among the barren rock dam (3), the barren rock middle partition dam (4) and the middle partition branch dams (4') by utilizing barren rocks in a rock disposal dump; and a space among the barren rock dam (3), the barren rock middle partition dam (4), the middle partition branch dams (4') and the barren rock pile (5) is a reservoir area for piled-up tailings (6), and is divided into a plurality of small areas which are communicated with one another. According to the method, by adopting a strengthening process technology of internal periphery strengthening, partitioning and area barren rock piling-up is adopted for the dry tailing storage yard, so that not only is the dry tailing storage yard strengthened, but also the piling-up problem of mineral barren rocks is solved, and therefore, land occupation by a project is saved.
Description
technical field [0001] The invention relates to a tailings safe stockpiling technology, in particular to a method for safely stockpiling tailings by using a waste rock dry stockpile, which can not only strengthen the dry tailings stockpile, improve the safety performance of the dry stockpile, but also solve the problem of The problem of the stacking site of mine waste rocks saves land resources. It is suitable for the reinforcement of various tailings dry storage yards, and can be widely used in tailings storage yards in black, non-ferrous, chemical and other industries. Background technique [0002] my country is one of the countries with the largest number of tailings ponds and tailings storage in the world. In the past, most mines solved the problem of tailings discharge by building or expanding ground tailings ponds. The concentration of tailings slurry is low and the water content is high. The stability coefficient of the tailings pond is low, especially in flood period...
