Abstract
Description
Technical Field
[0001] The present application relates to the technical field of mining chute construction, and in particular to a method for arranging a multi-segment unloading structure for a vertical high chute. Background Art
[0002] In mining production, with the continuous maturity of raise-boring technology, vertical high-pass chutes are widely used. Typically, each segmented mine tunnel is connected to the high-pass chutes to form an unloading chamber. Ore (slag) produced from multiple segments is unloaded at different elevations in the same chutes in different time periods, which can accelerate mine construction and improve production and transportation efficiency.
[0003] At present, for the current vertical high chute structure, iron sheets or meshes are mostly used for blocking and isolation at the connection between the unloading port of each segmented ore (slag) channel and the chute to ensure the safety of production operations and normal operation of construction.
[0004] However, this method of using iron sheets or mesh has many problems: when shoveling operations reach the unloading port, some slag in the upper section of the chute will fall through the gap to the section port, which may cause damage to the equipment; when the same chute is used simultaneously up and down, a large amount of slag in the upper section will break through the barrier and flow into the lower section unloading port, affecting the slag chute operation in the lower section; during shoveling operations, large pieces of slag with potential energy will flow into the lower section unloading port through the incision, which may cause splashing and injuring people, endangering the safety of the operators.
[0005] At the same time, mesh isolation materials such as iron sheets cannot completely and effectively block flying rocks, and are easily damaged and cannot be used for a long time. The isolation materials need to be replaced from time to time, and the replacement operation is risky. In addition, since the unloading ports of each section are connected to the main transport tunnel at a short distance, there is a possibility that floating rocks in the chute will splash into the main transport tunnel, affecting the shoveling operation and the passage of personnel, and the safety risk is high.

[0025] At present, for the current vertical high chute structure, iron sheets or meshes are mostly used for blocking and isolation at the connection between the unloading port of each segmented ore (slag) channel and the chute to ensure the safety of production operations and normal operation of construction.
[0026] However, this method of using iron sheets or mesh has many problems: when shoveling to the unloading port, some slag in the upper section of the chute will fall through the gap to the section port, which may cause damage to the equipment; when the same chute is used simultaneously, there is a possibility that a large amount of slag in the upper section will break through the barrier and flow into the lower section unloading port, affecting the slag shoveling operation in the lower section; during shoveling operations, large pieces of slag with potential energy will flow through the incision into the lower section unloading port, which may cause splashing and injuring people, endangering the safety of the workers. At the same time, mesh isolation materials such as iron sheets cannot completely and effectively block flying rocks, and are easily damaged and cannot be used for a long time. The isolation materials need to be replaced from time to time, which has a high risk of replacement operations. In addition, since the unloading ports of each section are connected to the main transport tunnel at a short distance, there is a possibility that floating rocks in the chute will splash into the main transport tunnel, affecting the shoveling operation and the passage of personnel, and posing a high safety risk.
[0027] In response to the above problems, an embodiment of the present application provides a method for arranging a multi-segment unloading structure for a vertical high chute, which can ensure the safety of the chute and effectively ensure the safety of production operations and normal construction operation.
[0028] The technical solutions of the embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0029] Figure 1 This is a schematic cross-sectional view of a multi-segment unloading structure in an embodiment of the present application; Figure 2 is a structural diagram of an anti-collision device in an embodiment of the present application; Figure 3 It is a structural diagram of the arrangement method in the embodiment of the present application.
[0030] See also Figure 1 A method for arranging a multi-segment unloading structure for a vertical high chute, wherein the multi-segment unloading structure for a vertical high chute includes: a vertical high chute 6 and a plurality of segmented connecting channels 7, and an anti-collision device is provided at the connection port between each segmented connecting channel 7 and the vertical high chute 6.
[0031] Specifically, the vertical high chute 6 is formed in one step by a raise boring machine, and the shaft diameter is determined according to actual construction requirements. The segmented channel 7 is formed according to the design and construction size of the unloading equipment.
[0032] In this embodiment, the diameter and shape of the shaft can be effectively controlled through a one-step construction method, ensuring the shaft's stability and load-bearing capacity, and reducing the need for subsequent maintenance. The size and shape of the segmented duct 7 are determined by the size of the unloading equipment, ensuring the normal operation of subsequent unloading operations.
[0033] The anti-collision device includes: a concrete hanging wall 1, a ring-mounted inverted wedge hanging pile 2, a series of steel wire ropes 3 and a steel structure crossbeam 4; the ring-mounted inverted wedge hanging pile 2 is embedded in the rock mass 8 at the connection port of the segmented link 7; the concrete hanging wall 1 is installed at the connection port of the segmented link 7 through the ring-mounted inverted wedge hanging pile 2; the series of steel wire ropes 3 pass through the rings of the ring-mounted inverted wedge hanging pile 2 and are connected into a mesh structure, serving as the internal steel structure skeleton of the concrete hanging wall 1; the steel structure crossbeam 4 is installed at the bottom of the concrete hanging wall 1.
[0034] In this embodiment, the concrete hanging wall 1 is embedded in the rock mass 8 by using a ring-shaped inverted wedge hanging pile 2, which can effectively fix the wall and the rock mass 8 to ensure the stable installation of the concrete hanging wall 1. By using a series of steel wire ropes 3 inside the wall to pass through the hanging pile rings to form a network, a steel structure skeleton inside the wall can be formed. This connection method ensures the firmness of each connection point and avoids the disconnection problem between the steel bar binding and the hanging pile. At the same time, by using steel structure materials as beams 4 at the bottom of the wall, the wear of the ore body on the lower part of the wall during unloading can be effectively reduced.
[0035] Specifically, an unloading port 5 is provided at the connection port of the segmented connecting channel 7, and the unloading port 5 is located at the bottom of the concrete hanging wall 1. The slope of the unloading port 5 is greater than the natural repose angle of the slag.
[0036] In this embodiment, by setting the unloading port 5, the ore can be unloaded more conveniently. At the same time, by setting the slope of the unloading port 5 to be greater than the natural repose angle of the slag, it can be ensured that the ore can slide smoothly during the unloading process, avoiding the ore being retained at the unloading port 5 due to insufficient slope, thereby ensuring unloading efficiency.
[0037] The arrangement method in this embodiment includes the following steps: S100: Step 1: embed and install the ring-mounted inverted wedge hanging pile 2 into the rock mass 8 at the connection port of the segmented connecting channel 7; Specifically: according to the size of the concrete hanging wall 1, the preset position of the concrete hanging wall 1 is determined; a ring-mounted inverted wedge hanging pile 2 is installed in the rock mass 8 on both sides of the bottom of the preset position, and then the remaining ring-mounted inverted wedge hanging piles 2 are installed in the rock mass 8 at equal intervals.
[0038] In this embodiment, by installing the ring-mounted inverted wedge hanging piles 2 at equal intervals, the force applied to each ring-mounted inverted wedge hanging pile 2 can be effectively dispersed, thereby improving the installation stability and impact resistance.
[0039] Specifically, the installation interval between the ring-mounted inverted wedge hanging piles 2 is 30 cm; the installation quantity of the ring-mounted inverted wedge hanging piles 2 is determined according to the cross-sectional size of the connecting port of the segmented connecting channel 7 and the installation interval.
[0040] In this embodiment, the circumference of the segmented duct 7 connection opening can be determined based on the cross-sectional dimensions of the connection opening and the installation spacing. This circumference is then divided by the installation spacing to determine the number of ring-mounted inverted wedge hanging stakes 2 to be installed. If the circumference is not divisible by an even number, the number of ring-mounted inverted wedge hanging stakes 2 to be installed is rounded up to ensure an even distribution of the hanging stakes 2 along the entire circumference.
[0041] Specifically, the ring-mounted inverted wedge hanging pile 2 is vertically embedded in the rock mass 8 .
[0042] In this embodiment, by vertically installing the ring-mounted inverted wedge hanging pile 2, the installation stability of the entire structure can be improved.
[0043] Specifically: before step 1, the arrangement method further includes: The size of the concrete hanging wall 1 is determined according to the size of the connecting port of the segmented connecting channel 7. This ensures that the concrete hanging wall 1 can effectively cover the connecting port, reduce the exposed area of the unloading port 5 area, and ensure production safety.
[0044] The diameter and embedment depth of the ring-wedge hanging pile 2 are determined based on the size of the concrete suspended wall 1. This ensures the load-bearing capacity and stability of the hanging pile 2, and ensures the stability of the subsequent installation of the concrete suspended wall 1. Specifically, when the length and width of the concrete suspended wall 1 are greater than 3 meters, a ring-wedge hanging pile 2 with a diameter of φ30 mm and an embedment depth of no less than 60 cm is selected.
[0045] S200: Step 2: Pass the series steel wire rope 3 through the rings of each of the ring-wedge hanging piles 2 to connect them into a mesh structure.
[0046] In this embodiment, by using a series of steel wire ropes 3 to pass through the rings of the ring-wedge hanging piles 2, a mesh structure is connected to serve as the internal steel structure skeleton of the concrete hanging wall 1. This can ensure the firmness of each connection point, avoid the disconnection problem between the steel bar binding and the hanging piles 2, and ensure the stability and durability of the subsequent pouring of the concrete hanging wall 1.
[0047] S300: Step 3: Place the steel structure beam 4 on the two ring-mounted inverted wedge hanging piles 2 on both sides of the bottom of the rock mass 8, and weld the steel structure beam 4 to the ring-mounted inverted wedge hanging piles 2 to fix them.
[0048] In this embodiment, the steel structure beam 4 is a channel steel, and the thickness of the channel steel corresponds to the thickness of the concrete suspended wall 1. Through welding, the steel structure beam 4 can be effectively fixed to ensure the normal progress of subsequent concrete pouring work. At the same time, the steel structure beam 4 can effectively reduce the wear of the ore body on the lower part of the wall during unloading, thereby improving the stability and durability of the concrete suspended wall 1.
[0049] S400: Step 4: Formwork is provided on both sides of the ring-shaped inverted wedge hanging pile 2, and concrete is poured. After the pouring is completed, the concrete hanging wall 1 is formed. Thus, the construction and production of the anti-collision device is completed.
[0050] In this embodiment, after the concrete pouring construction is completed, the anti-collision device can be integrated with the chute wall, effectively reducing the exposed area of the unloading port 5 area. At the same time, the anti-collision device has high strength and impact resistance, and the structural stability and durability are strong, which effectively avoids the safety risks brought by repeated replacement of isolation materials. It can also avoid the risk of floating stones in the chute splashing to the segmented link 7. When unloading multiple sections of the high chute at the same time, the anti-collision device can effectively improve the safety of the lower segment unloading operation area, avoid slag and stone from pouring into the lower segmented link 7, reduce the safety risks of shoveling equipment and personnel, and effectively improve production safety.
[0051] The technical solutions in the embodiments of the present application include the following beneficial effects: This application sets up a multi-segment unloading structure, which can realize the simultaneous operation of multiple sections of the high chute unloading and improve the utilization rate of the chute.
[0052] This application sets an anti-collision device, which can be integrated with the chute wall after construction is completed, effectively reducing the exposed area of the unloading port area. At the same time, the anti-collision device has high strength and impact resistance, and the structure is stable and durable, effectively avoiding the safety risks brought by repeated replacement of isolation materials, and can also avoid the risk of floating stones in the chute splashing to the segmented connecting track. When unloading multiple sections of a high chute at the same time, the anti-collision device can effectively improve the safety of the lower segment unloading operation area, avoid slag and stone from pouring into the lower segmented connecting track, reduce the safety risks of shoveling equipment and personnel, and effectively improve production safety.
