Development method of blind shaft frame for surface and underground parallel construction

Abstract

The invention relates to a development method of a blind shaft frame for surface and underground parallel construction, which belongs to underground mining and shaft construction techniques, in particular to a construction method of a main shaft development system. The method comprises the following steps that a sinking headframe is arranged on the ground; a shaft neck section is dug downward; a shaft hole, a shaft body and all horizontal horseheads are constructed; the sinking headframe is removed; a sheave wheel platform is arranged on the ground; a shaft tower foundation is constructed; slip-form construction is performed, so that the height of a shaft tower is 10 m; a hoisting rope is arranged in a penetrating manner; all horizontal development tunnels and chambers under a main shaft are constructed; additionally, a slip-form technique is adopted to construct the shaft tower on the ground, and surface and underground installation is performed at the same time. The development method has the advantages of novel concept, safety, reliability, surface and underground parallel construction and obvious benefits, the labor productivity is improved, the construction period is shortened, and a shaft is put into operation in advance.

Description

technical field

[0001] The invention belongs to the technical field of underground mining and well construction, and in particular relates to a construction method of a main well development system. Background technique

[0002] Shaft engineering is the main channel for lifting ore (waste) stone, transporting personnel and material equipment, ventilation and drainage during mine production, and is the throat of the entire mine construction. The main shaft is generally equipped with a skip, and its main function is to lift ore. The main shaft system includes the surface and subsurface engineering, the surface part includes the shaft tower (mine bin); the subsurface part includes: shaft neck, shaft body, various horizontal roadways and related chambers such as slip breaking and powder ore recovery system. In the downhole part of the main shaft system, the orientation of each horizontal horse head gate is inconsistent, the chambers are intricate, the construction is difficult ...

Embodiment Construction

[0039] 1. The construction of the main shaft system of Baixiangshan Iron Mine of Gushan Mining Company of Masteel Group uses construction machines including: hoist, sinking derrick, sinking stabilizer, sky wheel platform, bucket, grabbing machine, mine car, ground sliding form Hydraulic system.

[0040] 2. The construction of the main shaft system of Baixiangshan Iron Mine of Gushan Mining Company of Masteel Group adopts the underground derrick development method of parallel construction above and below the mine, and proceeds according to the following steps:

[0041] 1) Set the sinking derrick on the ground

[0042] a. According to the design coordinates, use the nearby plane and elevation control points to set the wellbore centerline 5 on the ground 1, set the wellbore cross line as the basis for the wellbore construction plane and elevation control, and set the lifting centerline 6 as the basis for the layout of the lifting facilities;

[0043] b. Set up the sinking derric...
