Problems solved by technology

[0003] For mines that use shaft development, the deep development system is usually formed in two ways: one is to form a new development system, the advantage of this method is that it does not affect the normal production of the mine's original development system during the infrastructure construction period of the deep engineering, However, the construction period is long, and the engineering quantity and construction investment are large; another way is to use the existing project to directly extend the system engineering such as the main shaft, auxiliary shaft, and air shaft in the mine's original development system to the deep part. The advantage of this method is that the construction period of the deep infrastructure is relatively short, and the amount of work and construction investment is small, but its biggest disadvantage is that the original development system of the mine cannot operate normally during the deep infrastructure construction, and the mine cannot maintain normal production

Embodiment 1

[0024] from figure 1 It can be seen that the forming method of this deep development system of the present invention comprises the following steps:

[0025] (1) Extend the air shaft a in the mine’s original development system A down to the lowest service middle section, and refit the air shaft to become a new auxiliary shaft 1; when the mine’s original development system A has multiple air shafts, it can be Occurrence range, inclination and extension orientation of the body, comprehensive selection can cover all or the largest range of deep ore bodies and the nearest wind shaft is extended and refitted as a new auxiliary shaft 1;

[0026] During the extension and modification of wind shaft a, it is necessary to form supporting works including the horse head gate 2 in the middle section, the central water tank 3 at the bottom of the shaft and the central water pump room 4, and complete the installation of shaft equipment, mechanical equipment, cables and pipelines;

Abstract

The invention discloses a formation method of a deep development system. The formation method comprises the following steps: (1) extending a ventilation shaft in an original development system of a mine downwards to a lowest service middle section and refitting into a new auxiliary shaft; during the ventilation shaft extending and refitting periods, continuously using an original main shaft and anoriginal auxiliary shaft in the original development system of the mine as a lifting system and maintaining the normal production of the mine; (2) opening the new auxiliary shaft, stopping the original auxiliary shaft, enabling a temporary lifting system to be composed of the new auxiliary shaft and the original main shaft and maintaining the normal production of the mine; (3) extending the original auxiliary shaft downwards to the lowest service middle section and refitting into a new main shaft; (4) enabling the new main shaft and the new auxiliary shaft to form a deep lifting system and continuously driving to form system engineering including an ore main pass so as to form the complete deep development system. The formation method disclosed in the invention has the benefits that in the deep construction process, the mine always has the complete main and auxiliary shaft lifting system, so that the normal operation can be maintained during the mine production; the construction amount and the construction investment can be reduced by making full use of the original development system of the mine.

Description

technical field [0001] The invention relates to the technical field of underground mining, in particular to a method for forming a deep development system. Background technique [0002] In the process of mine construction, in order to shorten the infrastructure construction time and reduce the infrastructure investment, construction and production are often carried out in a divided and phased manner, and the ore body is divided from top to bottom into the first phase, the second phase and other phases of phased construction and phased mining. . If the development system does not take into account the deep part during the construction of the first phase, the deep part needs to be re-formed as a development system. The mines that have made breakthroughs in deep prospecting will also face the problem of extending the deep development system. [0003] For mines that use shaft development, the current deep development system is usually formed in two ways: one is to form a new d...
