Problems solved by technology

[0003] For the land reclamation of the safety platform and cleaning platform, there are limited methods available. The traditional method is to build a retaining ridge on the outside of the safety platform and cleaning platform after the final step is formed, cover the inside of the retaining ridge, and carry out ecological restoration However, there are defects in the traditional method: first, after the steps are formed, the width of the safety platform and the cleaning platform is limited, so that the space for construction operations is limited; secondly, the bottom of the safety platform and the cleaning platform is generally a high and steep slope of 10-15m On the other hand, building retaining ridges on the outside of the safety platform and cleaning platform has the disadvantages of high risk factor and difficult construction; moreover, the equipment and materials used in the process of building retaining ridges are not common items in the mining process. Relevant equipment needs to be specially purchased or rented, which ultimately leads to high cost of reclamation, complicated process and difficult realization

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with specific embodiments.

[0039] Such as figure 1 and figure 2 Shown, a kind of reclamation method of open-pit mining safety platform and cleaning platform comprises the following steps:

[0040] (1) When the mining of the first step is completed and the mining and stripping of the second step starts to advance, the foundation trench 4 for reclamation is laid on the final platform 2 of the first step along the bottom line of the final side slope 1 of the first step; The rock structure in the reclamation trench 4 area is destroyed; the gravel in the reclamation trench 4 is cleaned by an excavator, and the gravel with an equivalent particle size of less than ¼h is screened and reserved at the bottom of the reclamation trench as a cushion. The thickness of the cushion layer is ½h; the soil is covered in the reclamation foundation trench 4, and the surrounding common vegetation is planted on the so...

Abstract

The invention belongs to the technical field of reclamation of open pit mining and particularly relates to a reclamation method of safety berms and cleaning berms formed after open pit mining. Bench mining from top to bottom is adopted for open pit mines and comprises steps as follows: (1) when first bench mining ends and second bench mining and stripping are started to be pushed, a reclamation foundation trench is dug on the final berm of the first bench; after completion, the reclamation foundation trench is covered with soil and afforestation is performed; (2) operation in the step (1) is repeated circularly, that is, after the (n-1)th bench mining ends and the nth bench mining and stripping are started to be pushed, a reclamation foundation trench is dug on the final berm of the (n-1)th bench, and n is a natural number larger than or equal to 3; after completion, the reclamation foundation trench is covered with soil and afforestation is performed. The method for reclamation duringmining has the advantages of being high in working efficiency, low in cost and easy to implement.

Description

technical field [0001] The invention belongs to the field of open-pit mining and reclamation, and in particular relates to a reclamation method for a safety platform for open-pit mining and a cleaning platform. Background technique [0002] Open-pit mines generally adopt the method of mining from top to bottom and divided into steps. Usually, after the mining is completed, several safety platforms and cleaning platforms will be formed; among them, the safety platforms and cleaning platforms are generally set one apart or two apart; the safety platform The width of the cleaning platform is generally 3-4m, the width of the cleaning platform is generally 6-8m, and the bedrock of each platform is exposed. [0003] For the land reclamation of the safety platform and cleaning platform, there are limited methods available. The traditional method is to build a retaining ridge on the outside of the safety platform and cleaning platform after the final step is formed, cover the inside...
