Abstract: Abstract: In coal mine shaft at the wellhead and bottom of the well, the structure form of four-corner shaft guide is often used to stabilize the lifting vessel. At present, the calculation method of horizontal force acting on four-corner shaft guide has not been reported. There is a large error between the calculation method of the horizontal force of the reference end and the measured horizontal force of the four corners of the channel. Based on this, the horizontal force of four-corner shaft guide in a super large coal mine in northern Shaanxi is tested in the field, and the calculation method of horizontal force of four-corner shaft guide in coal mine is established by using the unitary linear regression analysis model. The relationship between the horizontal force on the four-corner shaft guide acting on the lifting container and the lifting terminal load was obtained, and the formula for calculating the horizontal force on the front and side of the four-corner shaft guide acting on the lifting container was obtained. This method can provide a basis for the force analysis of the metal support structure at the shaft head and bottom of coal mine shaft and the design parameters of the four-corner shaft guide of coal mine shaft.
