A coal mine auxiliary shaft pipeline structure and its construction method

Abstract

The invention provides a coal mine auxiliary shaft pipe way structure and a construction method of the coal mine auxiliary shaft pipe way structure. The coal mine auxiliary shaft pipe way structure comprises a shaft body, an east ingate, a west ingate, a power substation, a water pump room and a pipe way inclined drift. The east ingate and the west ingate are arranged on the outer sides of the shaft walls of the two sides of the lower end of the shaft body, a pipe way level is in bypass connection with the shaft wall of the upper end of the east ingate, a pipe way transition level perpendicular to the pipe way level is arranged at the outer end of the pipe way level, and the pipe way transition level is communicated with the water pump room through the pipe way inclined drift. The whole pipe way level segment is constructed at one time, overall pouring is carried out on the whole pipe way level segment and the connected shaft wall, and therefore disturbance damage to the connected shaft wall and lower ingate masonry can be greatly reduced and eliminated when secondary construction is carried out on the rest of the pipe way level, and safe use of the shaft body and the ingates is guaranteed.

Description

technical field [0001] The invention relates to the field of coal mine shaft construction, in particular to a coal mine auxiliary shaft pipeline structure and a construction method thereof. Background technique [0002] Matoumen, the auxiliary shaft of the coal mine, is located at the throat of the mine. It has a large cross-sectional size, many chambers, and densely arranged adjacent chambers. Especially with the increase of the buried depth of the mine, the ground pressure increases and the stability of the surrounding rock is poor. Affected by the multiple disturbances caused by the construction of adjacent roadways and chambers, damage to the Matou gate and adjacent shaft walls in deep coal mines has occurred from time to time, seriously affecting the safe production of the mine. [0003] Coal mine auxiliary shaft pipeline usually refers to a section of drainage pipe laying from the water pump room to the vertical shaft shaft. It consists of three parts: level road, tran...

AI Technical Summary

Problems solved by technology

At this time, the adjacent well walls, Matou Gate and related chambers have been constructed and their permanent support has been completed. Since the current excavation construction mainly adopts the drilling and blasting method, the blasting shock wave will cause damage to the adjacent well walls, Matou Gate and related chambers. The surrounding rock and supporting structure of the chamber produce a large dynamic load, combined with excavation unloading and deformation disturbance of the surrounding rock, it is easy to cause instability and damage to the adjacent shaft wall, horse head door and related chambers, which seriously threatens the mine. production safety
