Description
Technical Field
[0001] This utility model relates to the field of mining technology, specifically to a blind skip hoisting ore transfer system. Background Technology
[0002] In related technologies, the blind skip shaft ore transfer system has a complex process with multiple ore transfer links. After the ore hoisted by the blind skip shaft is unloaded into the transfer bin, it needs to be loaded into mine cars. The mine cars transport the ore to the upper intermediate unloading station, unload it into the upper bin, and then load it onto the upper conveyor belt to enter the upper skip shaft. The vertical ore flow has a reversal route, which increases hoisting energy consumption. Ore transported by mine cars is prone to caking, causing some ore to stick to the car body, making unloading and bottom cleaning difficult. Multiple passages of ore through the chute increase the risk of chute blockage. The blind skip shaft has a large hoisting height, increases the shaft length, and involves a large amount of engineering work. Utility Model Content

[0038] The embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.
[0039] The following description, with reference to the accompanying drawings, describes an embodiment of the blind skip hoisting and ore transfer system of this utility model. For example... Figures 1 to 3 As shown, the blind skip hoisting and ore transfer system according to an embodiment of the present invention includes a blind skip 1, an upper skip 2, a first conveyor belt transport roadway 4, and a mine head ore bin 5.
[0040] The blind skip shaft 1 is located underground and extends vertically. It has a first loading chamber 11 at its lower part and a first unloading chamber 12 at its upper part. A hoisting room 13 is located at the top of the blind skip shaft 1. Drive equipment within the hoisting room 13 can move a first hoisting device 14 vertically within the blind skip shaft 1, so that the first hoisting device 14 can transport ore from the first loading chamber 11 to the first unloading chamber 12. Specifically, the first loading chamber 11 is located below the first unloading chamber 12. The first loading chamber 11 and the first unloading chamber 12 are connected to the blind skip shaft 1. The first hoisting device 14 can move between the first loading chamber 11 and the first unloading chamber 12 within the blind skip shaft 1, so that after the ore is loaded into the first hoisting device 14 located at the first loading chamber 11, the first hoisting device 14 will lift the ore upward to the first unloading chamber 12.
[0041] The upper skip 2 extends vertically, and its upper opening is connected to the surface. The lower part of the upper skip 2 has a second loading chamber 23. A shaft tower 21 located on the surface is provided above the upper skip 2. The drive equipment in the shaft tower 21 can drive the second hoisting equipment 22 to move vertically within the upper skip 2 so that the second hoisting equipment 22 can transport the ore in the second loading chamber 23 to the surface.
[0042] The first belt conveyor is installed in the first belt conveyor roadway 4. The first belt conveyor roadway 4 is connected to the second loading chamber 23. The first belt conveyor can transport the ore on it to the second hoisting equipment 22 located in the second loading chamber 23.
[0043] The mine shaft 5 is located above and connected to the first belt conveyor roadway 4. The discharge device of the mine shaft 5 can discharge ore from the mine shaft 5 onto the first belt conveyor. The mine shaft 5 is horizontally adjacent to the blind skip shaft 1. The first hoisting device 14 located in the first unloading chamber 12 can discharge ore into the mine shaft 5. For example, the discharge device of the mine shaft 5 is a vibrating ore discharger.
[0044] The blind skip hoisting and ore transfer system according to an embodiment of this utility model includes a blind skip hoist 1, an upper skip hoist 2, a first belt conveyor roadway 4, and a shaft head ore bin 5. The mined ore is loaded into a first hoisting device 14 located in the first loading chamber 11, and then hoisted to a first unloading chamber 12, before being discharged into the shaft head ore bin 5. The ore in the shaft head ore bin 5 can be discharged via a discharge device onto a first belt conveyor in the first belt conveyor roadway 4. The first belt conveyor transports the ore to a second hoisting device 22 located in the second loading chamber 23. Finally, the second hoisting device 22 hoists and transports the ore to the discharge bin of the shaft tower 21 at the surface, thus completing the ore transportation.
[0045] Compared to transporting ore from the first unloading chamber 12 to the transfer bin via mine cars, the blind skip shaft hoisting ore transfer system according to this embodiment of the invention sets up a shaft opening bin 5, which is adjacent to the first unloading chamber 12. This allows the first hoisting device 14 located in the first unloading chamber 12 to directly pour ore into the shaft opening bin 5. The shaft opening bin 5 can then directly discharge ore onto the first belt conveyor in the first belt conveyor roadway 4. This reduces the mine car transfer step, allowing ore to be discharged directly from the shaft opening bin 5 of the blind skip shaft 1, eliminating the need for a turnaround route in the entire ore transportation path 3, thereby reducing energy consumption and improving transportation efficiency.
[0046] like Figure 1As shown, in some embodiments, the ore transfer system of the blind skip shaft 1 further includes an upper ore bin 6. The upper ore bin 6 is located above and connected to the first belt conveyor roadway 4. The discharge device of the upper ore bin 6 can discharge the ore in the upper ore bin 6 onto the first belt conveyor. The upper opening of the upper ore bin 6 is connected to the upper transport intermediate section and unloading station 61. Specifically, the upper transport intermediate section and unloading station 61 includes an upper transport intermediate section roadway and an upper unloading station. The ore mined from the upper ore body can be passed through the upper transport intermediate section roadway to the upper unloading station, and then into the upper ore bin 6. That is, the ore mined from the upper ore body can be passed into the upper ore bin 6 through the upper transport intermediate section and unloading station 61. Thus, the first belt conveyor roadway 4 and the first belt conveyor within it can simultaneously transport ore for the upper ore bin 6 and the shaft head ore bin 5.
[0047] In some embodiments, the first belt conveyor roadway 4 extends along a first direction, which is perpendicular to the vertical direction. The upper ore bin 6 is located between the blind skip shaft 1 and the upper skip shaft 2 in the first direction. Specifically, the shaft opening ore bin 5 is located directly above the first belt conveyor, and in the second direction, it is located at the same position as the first belt conveyor roadway 4. The blind skip shaft 1 is arranged parallel to the shaft opening ore bin 5 in the second direction, and any two of the first, second, and vertical directions are perpendicular to each other. That is, the upper ore bin 6 is located between the shaft opening ore bin 5 and the upper skip shaft 2 in the first direction. For example, the blind skip shaft 1 is arranged parallel to the shaft opening ore bin 5 in the front-back direction. The first belt conveyor roadway 4 extends along a left-right direction, and the upper ore bin 6 is located between the blind skip shaft 1 and the upper skip shaft 2 in the left-right direction.
[0048] In some embodiments, the distance between the upper mine bin 6 and the blind trap shaft 1 in the first direction is greater than or equal to 30 meters and less than or equal to 50 meters. For example, the distance between the upper mine bin 6 and the blind trap shaft 1 in the first direction is 40 meters.
[0049] The distance in the second direction between the central axis of the blind skip shaft 1 and either the central axis of the shaft head ore bin 5 or the central axis of the first belt conveyor roadway 4 is greater than or equal to 10 meters and less than or equal to 15 meters. This allows the blind skip shaft 1 to be close to the shaft head ore bin 5, so that the first hoisting device 14 located in the first unloading chamber 12 can directly pour ore into the shaft head ore bin 5. For example, the distance in the second direction between the central axis of the blind skip shaft 1 and the central axis of the shaft head ore bin 5 is 12 meters.
[0050] In some embodiments, the bottom of the mine shaft ore bin 5 is higher than the bottom plate of the first belt conveyor roadway 4 by a first preset value, which is greater than or equal to 5 meters and less than or equal to 8 meters. This facilitates the discharge device of the mine shaft ore bin 5 in discharging material from the first belt conveyor in the first belt conveyor roadway 4. For example, the bottom of the mine shaft ore bin 5 is 6 meters higher than the bottom plate of the first belt conveyor roadway 4.
[0051] In some embodiments, the blind skip shaft 1 and the shaft head ore bin 5 are located between the two ends of the first belt conveyor (first belt conveyor tunnel 4) in the first direction. This allows the first belt conveyor (first belt conveyor tunnel 4) to have sufficient dimensions in the first direction to transport the ore discharged from the shaft head ore bin 5.
[0052] like Figures 1 to 3 As shown, in some embodiments, the blind skip shaft 1 hoisting ore transfer system also includes a second belt conveyor roadway 7 and a deep ore bin 8.
[0053] The second belt conveyor roadway 7 extends along the first direction and is connected to the first loading chamber 11. The second belt conveyor roadway 7 is equipped with a second belt conveyor, which can transport the ore on it to the first hoisting device 14 located in the first loading chamber 11.
[0054] The upper opening of the deep ore bin 8 is connected to the deep transport intermediate section and unloading station 81. The deep ore bin 8 is located above and connected to the second belt conveyor roadway 7. Specifically, the deep transport intermediate section and unloading station 81 includes a deep transport intermediate section roadway and a deep unloading station. Ore mined from the deep ore body can be transported through the deep transport intermediate section roadway to the deep unloading station, and then into the deep ore bin 8. That is, ore mined from the deep ore body can be transported into the deep ore bin 8 through the deep transport intermediate section and unloading station 81. The discharge device of the deep ore bin 8 can discharge the ore in the deep ore bin 8 onto the second belt conveyor, which can transport the ore on it to the first hoisting device 14 located in the first loading chamber 11.
[0055] In some embodiments, the deep ore bin 8 is spaced apart from the blind skip well 1 in the second direction. For example, the deep ore bin 8 and the blind skip well 1 are located on opposite sides of the wellhead ore bin 5 in the second direction (front-back direction).
[0056] In some embodiments, the first lifting device 14 is at least one of a skip or a cage. For example, the first lifting device 14 is a skip.
[0057] In some embodiments, the blind skip shaft 1 is equipped with a counterweight that cooperates with the first lifting device 14, or the blind skip shaft 1 is equipped with two cooperating first lifting devices 14. For example, the blind skip shaft 1 is equipped with a counterweight that cooperates with the first lifting device 14 to quickly lift the ore.
[0058] The blind skip shaft hoisting ore transfer system according to this embodiment of the invention reduces the mine car transfer process, directly discharging ore from the ore bin 5 at the head of the blind skip shaft 1 to the first belt conveyor in the first belt conveyor roadway. This eliminates the need for a turnaround route in the ore transport path 3, preventing ore from sticking to the car body, reducing unloading and bottom cleaning of the mine cars, and also reducing the risk of blockage caused by multiple ore passages through the chute. Furthermore, it reduces the hoisting height of the blind skip shaft 1, shortens the shaft length, and reduces the amount of engineering work. This reduces energy consumption and improves transport efficiency.
