Coal mine deep vertical shaft disturbance-resisting ingate structure

Abstract

The invention provides a coal mine deep vertical shaft disturbance-resisting ingate structure. An ingate comprises a first pouring section, a second pouring section, an auxiliary chamber and disturbance influence separation holes. The first pouring section is the first part to be constructed on the two sides of a shaft, and is poured integrally with a shaft wall. The second pouring section is arranged behind the first pouring section, a separation seam is formed between the first pouring section and the second pouring section, a foam plastic plate is arranged in the separation seam, the disturbance influence separation holes are formed in the first pouring section located on one side of the separation seam, and a shake station foundation is arranged under the auxiliary chamber. The first pouring section is lengthened, and disturbance influence of the second pouring section which is constructed subsequently on the near shaft wall is reduced. In addition, through the disturbance influence separation holes, the disturbance influence of the second pouring section which is constructed subsequently on the first pouring section and the near shaft wall is separated, and the coal mine deep vertical shaft disturbance-resisting ingate structure has wide practicability and operation ease.

Description

technical field [0001] The invention relates to the technical field of construction methods, in particular to an anti-disturbance horse head gate structure for a deep vertical shaft of a coal mine. Background technique [0002] The auxiliary shaft of the coal mine is used as a shaft for lifting personnel and materials. The horse head gate of the auxiliary shaft is located at the throat of the mine, and is the connection between the shaft of the auxiliary shaft and the parking lot at the bottom of the shaft. It has a large cross-section, complex structure, and various functional connections nearby. Chambers and alleyways. Usually, during the construction of Matoumen, first, the 3m-long part on both sides and the well wall are integrally poured, which is called the first pouring section, including the 3m-long Matoumen and the cradle foundation. Then continue to excavate the remaining part of the Matoumen, and at the same time dig the relevant chambers. Since the current exca...

AI Technical Summary

Problems solved by technology

Because blasting vibration, excavation and unloading, and surrounding rock deformation all have a great disturbance effect on the poured reinforced concrete arch and the adjacent shaft wall, in many engineering practices, it will cause bending of the steel bar at the top of the arch, concrete cracking, spalling and The well wall is damaged, which affects the safe use of the wellbore
