Embodiment Construction

[0031] In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that these embodiments may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to facilitate describing one or more embodiments.

[0032] The method for setting up a steep side mining platform of the present invention achieves the technical effect of increasing the working side slope angle in the side side area by increasing the interval between the steep side side platforms and adding a temporary safety platform and a temporary slag receiving platform.

[0033] Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] figure 1 The principle of the method of retaining the steep side mining platform is described ...

Abstract

The invention provides a steep slope mining platform reserving method, and belongs to the technical field of strip mining. According to the steep slope mining platform reserving method, a temporary safety platform and a temporary slag receiving platform are arranged in a direction vertical to a working slope in a temporary side slope area arranged by an inclined strip, a temporary transportation platform is arranged in the temporary side slope area, and in the temporary side slope area, platform reserving is carried out in a merged blasting mode. According to the method, the technical effectsof improving a working slope angle in the side slope area, delaying stripping, balancing a stripping ratio and further improving the economic benefit of a mine are achieved by increasing an interval between steep side slope platforms and additionally arranging the temporary safety platform and the temporary slag receiving platform.

Description

technical field [0001] The invention relates to the technical field of open-pit mining, in particular to a method for setting steep mining platforms. Background technique [0002] Because steep side mining has the characteristics of balancing the production stripping ratio and reducing the production stripping ratio in the early stage of open-pit mining, it is widely used in the open-pit mining process with deep ore deposits. [0003] However, the use of steep side mining in the steep side area has the problems of poor working conditions, frequent equipment transfers, reduced mining efficiency, and increased mining costs; therefore, in the prior art, the steep side area can only be used The slow side mining method leads to a small working side slope angle in the steep side side area, and delays rock stripping, which in turn leads to the disadvantage of wasting capital investment in the early stage. [0004] Therefore, there is an urgent need for a steep-side mining platform...
