Embodiment

[0012] A kind of adit ore-drawing shaft with reinforced shaft wall, such as figure 1 As shown, it includes an adit 1, an ore-drawing chute and a vertical shaft 8. The adit 1 is connected to the top of the auxiliary slope 2, and the bottom of the auxiliary slope 2 is connected to the ore-drawing chute shaft wall 3, and a loop is set between the vertical shaft 8 and the ore-drawing chute shaft wall 3. Wind roadway 7, manganese steel plate 4 is set on the ore-drawing chute shaft wall 3, and the bottom of ore-drawing chute and shaft 8 is communicated by passage 9, and transport vehicle 6 is provided in passage 9. A curved steel plate 5 is arranged at the joint between the manganese steel plate 4 and the shaft wall 3 of the ore-drawing chute.

[0013] The ore is directly poured into the ore-drawing chute from the adit 1, and reaches the bottom of the shaft through the auxiliary slope 2 and the ore-drawing chute shaft wall 3. The well wall 3 of the ore-drawing chute is generally no...

Abstract

The invention relates to an adit drawing ore-pass, in particular to an adit drawing ore-pass with a reinforcing well wall. The adit drawing ore-pass comprises an adit, a drawing ore-pass body and a vertical shaft. The adit is connected with the top of an auxiliary slope. The bottom of the auxiliary slope is connected with the well wall of the drawing ore-pass body. A ventilation roadway is arranged between the vertical shaft and the well wall of the drawing ore-pass body. A manganese steel plate is arranged on the well wall of the drawing ore-pass body. The drawing ore-pass body is communicated with the bottom of the vertical shaft through a channel. A transport cart is arranged in the channel. An arc-shaped steel plate is arranged at the joint of the manganese steel plate and the well wall of the drawing ore-pass body. The drawing ore-pass is good in ventilation effect and high in safety, the abrasion of ore on the well wall of the drawing ore-pass body can be relieved, and it is avoided that the well wall is damaged and ore gets stuck.

Description

technical field [0001] The invention relates to an adit ore-drawing chute, in particular to an adit ore-drawing chute with a reinforced shaft wall. Background technique [0002] The chute refers to the roadway that uses its own weight to slide iron ore from top to bottom. It is widely used in mines with adit development or shaft development. The ore drawing of the slide shaft is simple and reliable, and the management is convenient, especially when the height difference between the mining level and the main transportation level is greater, and the more stable the ore passes through the rock, the superiority of this ore drawing is more evident. This will play an important role in saving lifting and transportation equipment, saving power and material consumption. The impact of ore drawing during the ore-drawing chute is large, and the wear on the chute wall is relatively serious, and the shaft wall is prone to damage and ore jamming. Contents of the invention [0003] Aim...
