A type of inverted trousers-shaped chute structure system

Abstract

This invention discloses an inverted slit-shaped ore pass structure system, which includes stage transport roadways and segmented connecting ore passes. Each segmented connecting ore pass has symmetrical first and second connecting ore passes. Adjacent segmented connecting ore passes are connected by the second connecting ore pass to a collection connecting trough and a collection trough to form an inverted slit-shaped ore pass structure. Multiple inverted slit-shaped ore pass structures are interconnected to form an ore pass structure system. At the same time, the first connecting ore pass of each segmented connecting ore pass is connected to a separate segmented transport roadway, which solves the problem of normal unloading at both high and low positions, and avoids damage to the screens of the lower segment. Then, the part of the collection connecting trough that is longer than the collection trough is equipped with buffer pads. When the ore flows down, it will be buffered and slowed down by the buffer pads before flowing to the lower segment. Each segment has buffer pads to buffer the ore flow, reduce the impact force of unloading, reduce damage to the shaft wall, and reduce the problem of large amounts of dust during unloading. Overall, it realizes that the ore in each segment can flow down at a uniform and slow speed at the same time.

Description

Technical Field

[0001] This invention belongs to the field of mine chute structures, and specifically relates to an inverted trousers-shaped chute structure system. Background Technology

[0002] A ore pass is a tunnel that uses its own weight to cascade ore downhill. It is widely used in mines developed through adits or shafts. There are two common types of ore passes: one is the main ore pass, used to transfer ore or waste rock from the upper stages to the lower stages or lower ore bins, serving one or more stages; it is an auxiliary development tunnel. The other is the stope ore pass, used to transfer ore within the stope to the stage transport tunnels, serving one or more stopes; the latter is a preparatory tunnel. Non-coal mines are typically mined in multiple sections simultaneously. Ore from these sections is stored and unloaded through ore passes to the bottom stage transport tunnels for unified transport. The ore pass structure generally connects the main ore pass to each section for direct ore chutes. With the rapid development of science and technology, ore passes have been improved. However, in the use of existing technology, when unloading ore in high-level ore passes, due to the... Due to factors such as the speed of ore descent, lower sections cannot unload ore simultaneously to ensure safety. Even with branched staggered unloading, the ore will be blocked by the upper layer, preventing normal unloading. Furthermore, the impact force of falling ore can easily damage the lower section screens, disrupt the shaft structure, and generate a large amount of dust, affecting lower section production. Although using multi-stage chute gates to control ore chute discharge can reduce the impact force of falling ore and allow ore storage in multi-stage chutes, gate-controlled ore chute discharge is costly, difficult to construct, and inconvenient for subsequent maintenance. The storage capacity is also less than that of a straight chute. Moreover, with existing technology, the height difference and discharge speed difference between the transport roadways of each section result in uneven discharge, severely affecting the discharge rate and easily causing empty slots in the chute, thus affecting the storage capacity. Summary of the Invention

[0003] (a) Technical problems to be solved

[0004] To overcome the shortcomings of existing technologies, a reverse-shorts type ore pass structure system is proposed to address the problems encountered in existing technologies when unloading ore in high-level ore passes. Due to factors such as the speed of ore falling, lower sections cannot unload ore simultaneously to ensure safety. Even with branch staggered unloading, the ore is blocked by the upper ore, preventing normal unloading. Furthermore, the impact force of falling ore easily damages the lower section screens, disrupts the shaft wall structure, and generates a large amount of dust, affecting production in the lower section. Although using multi-section gates to control ore chute discharge can reduce the impact force of falling ore and store ore in multiple sections, gate-controlled ore chute discharge is costly, difficult to construct, inconvenient for subsequent maintenance, and has a lower storage capacity than straight ore passes.

[0005] Secondly, this addresses the issue that, when using existing technologies, the height differences and material feeding speed differences between the various transport tunnel sections lead to uneven material feeding in each section, severely affecting the feeding rate and easily causing empty slots in the ore pass, thus impacting ore reserves.

[0006] (II) Technical Solution

[0007] The present invention is achieved through the following technical solution: The present invention proposes an inverted trousers-shaped chute structure system, the structure of which includes a mine tunnel structure, a mountain body, and an ore body, wherein the ore body is provided in the mountain body, and the mine tunnel structure is used to transport the ore body out of the mountain body;

[0008] The mine tunnel structure includes stage haulage tunnels, segmented connecting chutes, bottom connecting chutes, and unified haulage tunnels. The unified haulage tunnel is located at the bottom of the mountain, with one end penetrating the mountain. The top of the unified haulage tunnel is connected to the bottom of the bottom connecting chutes, and the top of the bottom connecting chutes is connected to the stage haulage tunnels through segmented connecting chutes.

[0009] The staged haulage roadway includes a top haulage roadway, a first segment haulage roadway, a second segment haulage roadway, a third segment haulage roadway, and a bottom haulage roadway. All of these roadways communicate with the ore body. The ends of each roadway, away from the ore body, are connected to different segmented connecting chutes. The bottom of the connecting chutes connected to the bottom haulage roadway communicates with the top of a unified haulage roadway via a bottom connecting chute. The third segment haulage roadway is located above the bottom haulage roadway. The segmented connecting chute of the three-section transport roadway is connected to the segmented connecting chute of the bottom transport roadway. The second segmented transport roadway is located above the third segmented transport roadway, and the segmented connecting chute of the second segmented transport roadway is connected to the segmented connecting chute of the third segmented transport roadway. The first segmented transport roadway is located above the second segmented transport roadway, and the segmented connecting chute of the first segmented transport roadway is connected to the segmented connecting chute of the second segmented transport roadway. The top transport roadway is located above the first segmented transport roadway, and the segmented connecting chute of the top transport roadway is connected to the segmented connecting chute of the first segmented transport roadway.

[0010] The segmented connecting chute is provided in two or more parts. Each segmented connecting chute includes a collection trough, a buffer pad, a collection connecting trough, a first connecting chute, and a second connecting chute. The collection trough is an inverted isosceles trapezoidal trough. The top of the collection trough is connected to the collection connecting trough, and the bottom of the collection trough is connected to the bottom connecting chute or the second connecting chute. The long side of the top of the collection trough is shorter than the long side of the collection connecting trough, and the short side of the top of the collection trough is the same size as the short side of the collection connecting trough. Both sides of the long side of the collection connecting trough are longer than the collection trough by the same distance, and the extended part is provided with a buffer pad. One side of the top of the long side of the collection connecting chute of one segmented connecting chute is connected to the bottom of the collection trough of another segmented connecting chute through the second connecting chute. The side of the top of the long side of the collection connecting chute away from the second connecting chute is connected to the top transport tunnel, the first segmented transport tunnel, the second segmented transport tunnel, the third segmented transport tunnel, or the bottom transport tunnel through the first connecting chute. The two connected segmented connecting chutes are located on intersecting vertical planes.

[0011] Furthermore, the top transport roadway, first segment transport roadway, second segment transport roadway, third segment transport roadway, bottom transport roadway, and unified transport roadway are opened from top to bottom, while a safe mining height is left between adjacent roadways. The optimal interval between adjacent top transport roadways, first segment transport roadways, second segment transport roadways, third segment transport roadways, bottom transport roadways, and unified transport roadways is 15 meters. The number of first segment transport roadways, second segment transport roadways, and third segment transport roadways can be increased or decreased depending on the height of the mine.

[0012] Furthermore, the buffer pad can be made of mineral powder.

[0013] Furthermore, the first connecting chute, the second connecting chute, the bottom connecting chute, and the bottom of the collecting trough are all the same size, and the connection point between the top transport tunnel, the first segment transport tunnel, the second segment transport tunnel, the third segment transport tunnel, or the bottom transport tunnel and the first connecting chute is also the same size.

[0014] Furthermore, the optimal angle between the vertical planes of the two connected segmented chutes is 90 degrees.

[0015] (III) Beneficial Effects

[0016] One of the above technical solutions has the following advantages or beneficial effects:

[0017] 1) To address the challenges of existing technologies in high-level ore chute unloading, where the speed of ore descent and other factors prevent simultaneous unloading of lower sections to ensure safety, even with branch-style staggered unloading, ore is often blocked by upper-level ore, hindering normal unloading. Furthermore, the impact of falling ore damages lower section screens, disrupts the shaft structure, and generates significant dust, impacting lower section production. While multi-section gate control for ore chute unloading reduces impact and allows storage in multiple sections, it is costly, difficult to construct, and requires maintenance, with lower storage capacity compared to straight ore chutes. Therefore, a system with a collection trough connecting the various transport roadways via chutes is proposed. Then, the various collection troughs are connected through other chutes until they are connected to a unified transport roadway, realizing a chute system with an inverted trousers structure. At the same time, the adjacent segmented connecting chutes are all located on intersecting vertical planes. With the addition of buffer pads on the part of the connecting chutes that are longer than the collection chutes, the falling ore will be buffered and slowed down by the buffer pads before changing direction and entering the collection chutes. This process continues until the ore falls into the unified transport roadway. Since the connecting chutes of each segmented connecting chute and the connecting chutes of the stage transport roadway are separate, it can be ensured that the ore is directly chuteted into the unified transport roadway. At the same time, it can also ensure that the ore can be unloaded normally in the lower transport roadway when unloading at a high level. This can also better reduce the impact force of unloading at a high level, better prevent damage to the lower segmented screens and shaft walls, and avoid the problem of excessive dust during unloading.

[0018] 2) To address the issue that existing technologies suffer from uneven material feeding due to differences in height and feeding speed among the various transport roadways, severely impacting the feeding rate and leading to empty troughs in the ore chute and affecting ore storage capacity, an inverted isosceles trapezoidal collecting trough is installed. Ore unloaded from higher levels is buffered and decelerated by a buffer pad, then slides down along one side of the isosceles trapezoid. Ore unloaded from the new stage transport roadway also slides down from the other side after being buffered. This ensures that the ore entering the collecting trough of the segmented connecting ore chute is slowed down and mixed evenly with the ore unloaded from the new stage transport roadway, thus better ensuring uniform feeding across each segment and reducing empty troughs in the ore storage, thereby increasing ore storage capacity.

Detailed Implementation

[0026] The present invention will be further described in detail below with reference to embodiments, but the implementation of the present invention is not limited thereto.

[0027] The present invention provides an inverted trousers-shaped chute structure system: its structure includes a mine tunnel structure 1, a mountain body 2, and an ore body 3, wherein the ore body 3 is provided inside the mountain body 2, and the mine tunnel structure 1 is used to transport the ore body 3 out from the mountain body 2;

[0028] The mine tunnel structure 1 includes a stage transport tunnel a, a segmented connecting chute b, a bottom connecting chute c, and a unified transport tunnel d. The unified transport tunnel d is located at the bottom of the mountain 2. One end of the unified transport tunnel d penetrates the mountain 2. The top of the unified transport tunnel d is connected to the bottom of the bottom connecting chute c. The top of the bottom connecting chute c is connected to the stage transport tunnel a through the segmented connecting chute b.

[0029] The stage transport roadway a includes a top transport roadway a1, a first segment transport roadway a2, a second segment transport roadway a3, a third segment transport roadway a4, and a bottom transport roadway a5. One end of each of the top transport roadway a1, first segment transport roadway a2, second segment transport roadway a3, third segment transport roadway a4, and bottom transport roadway a5 is connected to the ore body 3. The ends of the top transport roadway a1, first segment transport roadway a2, second segment transport roadway a3, third segment transport roadway a4, and bottom transport roadway a5 away from the ore body 3 are respectively connected to different segmented connecting chutes b. The bottom of the segmented connecting chutes b connected to the bottom transport roadway a5 is connected to the top of the unified transport roadway d through a bottom connecting chutes c. The top transport roadway a1, the first segment transport roadway a2, the second segment transport roadway a3, the third segment transport roadway a4, and the bottom transport roadway a5 are arranged from top to bottom. The top transport roadway a1, the first segment transport roadway a2, the second segment transport roadway a3, the third segment transport roadway a4, and the bottom transport roadway a5 are not interconnected. Two adjacent roadways of the top transport roadway a1, the first segment transport roadway a2, the second segment transport roadway a3, the third segment transport roadway a4, and the bottom transport roadway a5 are connected by connecting chutes b of different segments. The stage transport roadway a may have more or fewer first segment transport roadways a2, second segment transport roadways a3, and third segment transport roadways a4 depending on the height of the mine.

[0030] The segmented connecting chute b has the same number of chutes as the stage transport chute a, including the top transport chute a1, first segmented transport chute a2, second segmented transport chute a3, third segmented transport chute a4, and bottom transport chute a5. The segmented connecting chute b includes a collection trough b1, a buffer pad b2, a collection connecting trough b3, a first connecting chute b4, and a second connecting chute b5. The collection trough b1 is an inverted isosceles trapezoidal trough, with its top connected to the collection connecting trough b3. The bottom of the collection trough b1 is connected to either the bottom connecting chute c or the second connecting chute b5. The long side of the top of the collection trough b1 is shorter than the long side of the collection connecting trough b3, and the short side of the top of the collection trough b1 is the same size as the short side of the collection connecting trough b3. The long side of trough b3 is longer than the collecting trough b1 by the same distance on both sides, and the extended part is provided with a buffer pad b2. When two different segmented connecting chutes b are connected, the top of the long side of the collecting connecting trough b3 of one segmented connecting chute b is connected to the bottom of the collecting trough b1 of the other segmented connecting chute b through the second connecting chute b5. The top of the long side of the collecting connecting trough b3 away from the second connecting chute b5 is connected to the top transport lane a1, the first segmented transport lane a2, the second segmented transport lane a3, the third segmented transport lane a4, or the bottom transport lane a5 through the first connecting chute b4. The two connected segmented connecting chutes b are located on intersecting vertical planes, and the angle of intersection of the vertical planes of the two connected segmented connecting chutes b is 90 degrees.

[0031] Among them, a safe mining height is reserved between each two adjacent tunnels in the top transport tunnel a1, the first segment transport tunnel a2, the second segment transport tunnel a3, the third segment transport tunnel a4, the bottom transport tunnel a5, and the unified transport tunnel d, with a mining height of 15 meters being optimal.

[0032] The buffer pad b2 can be made of mineral powder.

[0033] Among them, the first connecting chute b4, the second connecting chute b5, the bottom connecting chute c and the bottom of the collection trough b1 are all the same size, and the connection point between the top transport lane a1 or the first segment transport lane a2 or the second segment transport lane a3 or the third segment transport lane a4 or the bottom transport lane a5 and the first connecting chute b4 is all the same size.

[0034] The optimal angle between the vertical planes of the two connected segmented chute b is 90 degrees.

[0035] This invention provides a segmented connecting ore pass b with symmetrical first connecting ore pass b4 and second connecting ore pass b5. The symmetrical first connecting ore pass b4 and second connecting ore pass b5 are connected to a collecting trough b1 via a collecting connecting trough b3. The upper collecting trough b1, which is an inverted isosceles trapezoid, connects to the lower second connecting ore pass b5, forming an inverted slit-shaped ore pass structure. Adjacent upper and lower segmented connecting ore passes b are interconnected through this inverted slit-shaped ore pass structure to form a ore pass structure system. Adjacent segmented inverted slit-shaped ore pass structures are located on intersecting vertical planes. This inverted slit-shaped ore pass structure system allows each segmented collecting connecting trough b3 to be connected to a separate stage transport roadway a via the first connecting ore pass b4, solving the problem of simultaneous high-level segmented ore unloading and low-level segmented ore unloading. The ore can be unloaded normally in each section, while also preventing damage to the screens in the lower sections. The collecting connecting trough b3 is longer than the collecting trough b1. Buffer pads b2 are placed directly below the connection points between the first connecting chute b4, the second connecting chute b5, and the collecting connecting trough b3. When ore enters the upper section connecting chute b, it is first buffered and slowed down by the buffer pads b2 before changing direction and flowing to the lower section connecting chute b. Each section connecting chute b has the same buffer pads b2 for buffering the ore flow, better reducing the impact of high-level unloading, effectively reducing damage to the shaft walls, and reducing the problem of excessive unloading dust. Overall, it achieves simultaneous, uniform, and slow ore flow from each section. The specific implementation plan is as follows:

[0036] During equipment operation, when unloading ore in each segment's stage transport roadway a, the top transport roadway a1, first segment transport roadway a2, second segment transport roadway a3, third segment transport roadway a4, and bottom transport roadway a5 can all transport the ore mined from ore body 3 to their respective independently connected segment connecting chutes b. The ore is then unloaded from the top of the first connecting chute b4 of each independently connected segment connecting chute b. This allows the ore from each segment's stage transport roadway a to slide from the first connecting chute b4 onto a buffer pad b2 located on the portion of the collecting connecting chute b3 that extends beyond the collecting chute b1, where it is slowed and buffered. The ore then slides into the collecting chute b1. At this point, the collecting chute b2 of the segment connecting chute b1 connected to the top transport roadway a1... Ore from section 1 will be discharged from the second connecting chute b5 of the adjacent first section transport roadway a2 to the collection connecting chute b3 of the first section transport roadway a2. The ore discharged from the second connecting chute b5 falls onto the buffer pad b2 located on the side of the collection connecting chute b3 that is longer than the collection chute b1 away from the first connecting chute b4, where it is slowed down and buffered. Then, it is discharged from the collection connecting chute b3 of the first section transport roadway a2 into the collection chute b1 of the first section transport roadway a2. At this time, since the collection chute b1 connected to the top transport roadway a1 and the collection chute b1 connected to the first section transport roadway a2 are on intersecting vertical planes, the ore entering the first section transport roadway from the top transport roadway a1 into the collection chute b1 is slowed down. The ore in the haulage roadway a2 connected to the collection trough b1 will undergo a shunting and redirection process, thereby slowing down again. Then, the ore shunted from the top haulage roadway a1 will mix with the ore shunted from the first segment haulage roadway a2 in the collection trough b1 connected to the first segment haulage roadway a2. Following the same principle of mixing with the ore shunted from the top haulage roadway a1 and the first segment haulage roadway a2, the ore in the collection trough b1 connected to the first segment haulage roadway a2 will also shunt to the collection trough b1 of the second segment haulage roadway a3, mixing with the ore mined and shunted from the second segment haulage roadway a3. This process can be repeated indefinitely, with multiple stages of haulage roadways a used for shunting. At each stage, the ore in the collection trough b1 connected to the haulage roadway a2 will slow down and mix with the ore in that stage's collection trough b1. The ore is mixed and discharged in the conveying roadway until it reaches the collection trough b1 of the bottom transport roadway a5. After mixing with the ore discharged from the bottom transport roadway a5, it is discharged from the bottom connecting chute c to the unified transport roadway d, which facilitates subsequent transportation from the unified transport roadway d. Since the connecting chutes connected by each segment connecting chute b and the connecting chutes of each stage transport roadway a are separate, it can ensure that the ore is discharged directly to the unified transport roadway d. At the same time, it can ensure that the ore can be discharged normally in the lower transport roadway when the ore is discharged at a high level. In addition, since the collection trough b1 of each stage transport roadway a can buffer, decelerate and change direction to decelerate the discharged ore, it can better reduce the impact force of high-level ore discharge, better prevent damage to the lower segment screen and shaft wall, and avoid the problem of large amount of dust during ore discharge.

[0037] Furthermore, since the collection trough b1 of each segment connecting chute b is an inverted isosceles trapezoid, the ore unloaded at the high level, after being buffered and decelerated by the buffer pad b2 and deflected, will enter the collection trough b1 and slide down from one side of the isosceles trapezoid. The ore unloaded in the new stage transport roadway a will also be buffered and decelerated before sliding down to the other side of the isosceles trapezoid of the collection trough b1 and sliding down again. This will slow down the ore entering the collection trough b1 of each segment connecting chute b and mix it with the ore unloaded in the new stage transport roadway a before being evenly discharged. This will better ensure even material distribution in each segment and reduce empty storage troughs, thereby increasing the storage capacity.
