Abstract

The invention discloses a construction method and structure for a vertical shaft. The vertical shaft construction method comprises the steps of digging a draw shaft horizontally from a bottom roadway or a bottom underground chamber to the earth surface or above, wherein the draw shaft has multiple fold line segments and the whole body of the draw shaft moves upward along the center line of the vertical shaft; according to the stabilization and fixation condition of surrounding rocks, conducting segment blast on the draw shaft. According to the construction method and structure for the vertical shaft, the complexity of the construction process of the vertical shaft can be reduced, the construction of the vertical shaft is more simple and convenient, and the construction cost of the vertical shaft is reduced.

Description

technical field [0001] The invention relates to the technical field of underground mine construction, in particular to a construction method and construction structure of a shaft. Background technique [0002] At present, the main methods for constructing shafts in domestic underground mines include hanging tank method, climbing tank method, deep hole blasting method, and raised shaft method. These methods are conventional construction methods, and all have defects in varying degrees, such as: complex construction process, high technical requirements, high construction cost, etc. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, the main purpose of the present invention is to provide a construction method for a shaft, which aims at reducing the complexity of the construction process of the shaft, making the construction of the shaft simpler and more convenient, a...
