Description

Underground mine waste rock loading roadway structure

Technical Field

The utility model belongs to the field of mine production, and particularly relates to a gangue loading roadway structure.

Background

For an underground mine which is constructed in a foundation or is being produced, a large number of roadways or chambers need to be constructed in time according to a plan, and the roadways or chambers can generate a large number of waste rocks during construction due to blasting, so that the waste rocks can be quickly lifted and conveyed to the ground surface from the tunnel face through a middle section roadway and then through a vertical shaft cage, and the underground mine is one of key works which restrict the safety of mine construction and production progress. At present, two conventional methods are generally adopted for loading and transporting the gangue in the underground roadway.

One is rail transportation, a gangue raking machine is closely attached to the tunnel face, gangue is raked into a mine car, the mine car is pushed to a car storage section after being filled with the gangue, an empty mine car is pushed to the rear end of the gangue raking machine, and the gangue is raked into the empty mine car in the same way until the gangue is completely filled or all mine cars to be used are filled with the gangue. And then, a train of mine cars filled with the gangue is transported to a vertical shaft yard by the electric locomotive, and the mine cars are lifted to the ground surface through the cage for unloading. However, in this method, a scraper loader needs to be installed on the face of each driving tunnel, and the moving track required by the scraper loader needs to be installed to the rear end of the working position of the scraper loader in time after each blasting, otherwise the scraper loader cannot reach the working position. When the tunnel is tunneled and blasted, blasting flying stones usually cover the track, so that the track needs to be cleaned before raking the gangue every time, and the raking machine and the mine car can move smoothly, which is labor-consuming and time-consuming. When the gangue raking machine rakes the gangue, after one mine car is full, the expanded mine car needs to be pushed out and then another mine car needs to be pushed to load the gangue, and the working procedure time is long. And this kind of mode can not be at the face of a plurality of tunnels simultaneously the harrow waste rock, and efficiency is also lower.

And the other type is trackless transportation, wherein a scraper is used for loading the blasted waste rock to a trackless transport vehicle on the tunnel face of the tunnel, the vehicle is transported to a waste rock field near a vertical shaft train field for unloading the waste rock, the waste rock in the waste rock field is loaded to a mine car through the scraper, the mine car is transported to a gate of a horse head at the lower middle section of the vertical shaft through a rail, and then the mine car is lifted to the ground surface for unloading through a cage. However, the vehicle of this method is in a trackless moving state, and in consideration of the large volume and the driving safety of the vehicle, the vehicle can only be used in a transportation roadway with a large section, and is difficult to be used in a transportation roadway with a small section. And trackless automobile transportation can produce a large amount of automobile exhaust, pollutes tunnel ventilation quality, and the car cost is higher, and it still forms the secondary near shaft parking lot to transport simultaneously, and is time-consuming and laborious, and the cost is relatively higher.

The Chinese patent application numbers are: CN201410491610.6, published date: 2015 3/11 discloses a belt type storage and transportation machine for a downhole driving working face and a method for storing and transporting gangue, wherein an upper carrier roller and a lower carrier roller are arranged on a rack at intervals, rotary rollers are arranged at two ends of the rack, a pair of driving rollers and tensioning rollers are arranged below the rack, and the driving rollers are dragged to operate by a driving device; vertical braces are fixedly connected to two sides of the rack at intervals, and an upper material baffle plate is installed through the vertical braces to form a groove type space above the conveying belt; the driving device consists of a permanent magnet direct current driving variable frequency speed regulating motor and a frequency converter, and the motor is rigidly connected with the driving roller through an elastic pin coupling. When the tunneling head is used for discharging the waste rock, the delivered waste rock is accumulated in the groove type space of the storage and transportation machine which runs at a constant speed, and when the storage is full, the operation is stopped to wait for unloading; and when the coal conveying of the large conveying system is idle, quickly unloading the stored gangue onto the conveying system of the large roadway. Although the storage and transportation machine can effectively improve the gangue transportation efficiency, the storage and transportation machine is high in manufacturing cost, and the device needs to be continuously arranged forwards along with continuous development of a roadway, so that the working efficiency is reduced, the arrangement cost is increased, and the storage and transportation machine is not suitable for gangue transportation of the roadway at the blasting development stage.

The Chinese patent application numbers are: CN201210295433.5, published date: the patent document of 2012, 11 and 28 discloses a method for lifting gangue from a main shaft of a coal mine, which comprises the steps of firstly transforming the existing mining area yard to ensure that the existing mining area yard is suitable for the operation of a 3-ton bottom-dump mine car; secondly, the gangue transportation operation flow is as follows: loading 3 tons of bottom-dump mine cars into the gangue produced at the head of each tunneling head by using a raking loader, hoisting the gangue to a large transportation lane by using a mining area winch after the gangue is transported to a mining area yard, and after the large transportation lane is centralized to the number of a train, using a power locomotive to pull the gangue to a modified 3 tons of bottom-dump mine car unloading station for unloading and storage; when the coal lifting time of the main shaft is idle, the coal is transferred to the main shaft skip, lifted to the ground through the main shaft, and transported to a gangue brick factory by a special ground belt conveyor. The method is the trackless transportation method mentioned above, and has the problem that the method is difficult to be applied to a small-section transportation roadway.

Detailed Description

The utility model is further described with reference to specific embodiments and the accompanying drawings.

Examples

A gangue loading roadway structure of an underground mine is used for transporting gangue generated during blasting of a driving roadway away in underground mine mining operation so that construction can be normally carried out, and the specific structure and the working principle of the gangue loading roadway structure are described in detail below.

As shown in fig. 1 to 3, the gangue loading roadway structure mainly comprises a transportation roadway 1, a transportation rail 2, a scraper vehicle 3, a driving roadway 4, a side gangue blocking device 5 and a middle gangue blocking device 7.

Wherein, the transportation track 2 sets up in haulage roadway 1, extends along haulage roadway 1's length direction, is equipped with mine car 6 on it. The excavation roadway 4 is provided with at least one, the inlets are all arranged on one side of the transportation track 2, the number of the inlets is 9 in the embodiment, and the other side of the transportation track 2 is provided with a side gangue blocking device 5. The scraper conveyor 3 is arranged on one side of the transportation rail 2 close to the excavation roadway 4 and is used for conveying the gangue in the excavation roadway 4 to the mine car 6.

Through the arrangement structure, one haulage roadway 1 can be used for loading and transporting the gangue of a plurality of tunneling roadways 4 at the same time, and the haulage roadway 1 is suitable for haulage roadways 1 with various sizes and cross sections. When the section of the haulage roadway 1 is large, a mine car 6 with extremely large capacity can be arranged on the haulage track 2, and the gangue in a plurality of tunneling roadways 4 can be loaded and transported away at one time; when the section of the haulage roadway 1 is small, a plurality of mine cars 6 can be arranged on the haulage track 2 to correspond to one tunneling roadway 4, so that the gangue in the tunneling roadway 4 can be transported away at one time, and compared with a conventional roadway structure, the time for waiting for the previous mine car 6 to be transported away is shortened, and the loading and transporting efficiency of the gangue is effectively improved. Meanwhile, by arranging the side waste rock blocking device 5, the situation that waste rock is scattered onto the transportation track 2 from one side of the mine car 6 when the waste rock is loaded and transported into the mine car 6 is avoided, and the normal transportation of the mine car 6 is ensured.

Specifically, as shown in fig. 4, the side fence device 5 includes a cross member 51, a rectangular frame 52, and a side fence 53. Wherein the cross beam 51 is fixedly mounted on the wall of the haulage roadway 1 by means of anchor rods 54 and extends in the length direction of the haulage roadway 1. The rectangular frame 52 has a plurality of frames, and is arranged along the length direction of the cross member 51 and fixedly welded to the cross member 51.

The longitudinal beams 72 pass through the a-frames 71 and are welded to the a-frames 71, thereby fixing the a-frames 71 together. The intermediate waste rock blocking plates 73 are fixedly installed on the two side surfaces of the A-shaped frame 71, and cover the gap between the A-shaped frame 71 and the two side surfaces thereof. In order to enable the outer side surfaces of the A-shaped frames 71 to be located in the same plane so as to facilitate installation of the middle gangue plates 73, in the embodiment, the longitudinal beams 72 are fixedly installed at the top ends of the inner sides of the A-shaped frames 71, and the A-shaped frames 71 can be clamped on the longitudinal beams 72 in the same state by combining the structural characteristics of the A-shaped frames 71. In order to further improve the connection strength between the a-frames 71, in this embodiment, a connecting beam 74 respectively connecting two side surfaces of the a-frame 71 is fixedly mounted at the middle portion of the a-frame 71, and the connecting beams 74 of the a-frames 71 are fixedly connected to one reinforcing beam 75. In this embodiment, the middle gangue plates 73 are made of iron sheet, and have high wear resistance.

When a plurality of mine cars are adopted, the lower ends of the two sides of the A-shaped frame 71 are respectively erected on the two mine cars 6, so that the gap between the mine cars 6 can be effectively covered, and when the gangue falls on the middle gangue blocking device 7, the gangue can slide into the mine cars 6 from the two side surfaces of the A-shaped frame 71, the time for cleaning the track is reduced, and the gangue loading efficiency is effectively improved.

In conclusion, the underground mine waste rock loading roadway structure of the embodiment can efficiently transport the blasted waste rock away, has no limitation on the size of the section of the transportation roadway, and reduces the waste rock transportation cost.
