Problems solved by technology

[0004] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a mine chute system, which is used to solve the problem of increasing the height of the transportation stage in order to reduce the number of reverse sections in the later stage when the chute is used in the prior art to draw ore. If this is not the case, it will lead to an increase in the number of piercing projects during the infrastructure construction period, which will further increase the technical problem of project investment costs.

Abstract

The invention provides a mine draw shaft system. The draw shaft system comprises an input material conveying channel, a material sieving device, a first draw shaft and an output material conveying channel, wherein the input material conveying channel is connected with one end of the first draw shaft; the material sieving device is installed at one end of the first draw shaft; the other end of thefirst draw shaft is connected with one end of a second draw shaft, the first draw shaft is oblique, and the second draw shaft is straight; the output material conveying channel is formed in the lowerportion at the other end of the second draw shaft. In this way, the first draw shaft is oblique, and the second draw shaft is straight so that the length of a transverse drift roadway can be shortened, wherein the length of the transverse drift roadway is from an ore body to the other end of the second draw shaft. Therefore, the engineering investment cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of mining engineering, in particular to a mine shaft system. Background technique [0002] During the mining process, the use of slide shafts to transport the materials produced in the stope is the best way to improve production efficiency. [0003] However, in the design of the chute, in order to reduce the number of inversions in the later stage, the height of the transportation stage is generally increased; however, after the height of the transportation stage is increased, the distance between the chute outside the vein and the ore body will increase, which will lead to the increase in the construction period. The length of the vein-piercing roadway increases, which increases the investment cost of the project. Contents of the invention [0004] Aiming at the problems existing in the prior art, the embodiment of the present invention provides a mine chute system, which is used to solve the problem of ...
