Description

Technical Field

[0001] The present invention relates to the field of industrial and mining transportation technology, and in particular to an integrated system of an intelligent coal mine transportation platform. Background Art

[0002] Coal mines refer to underground or surface mines where coal is mined. Coal is obtained from the ore layers of coal mines through mining, transportation, processing and storage, and is ultimately used in industry, energy and other fields. Coal mines are one of the important basic energy sources for energy production. Globally, coal remains one of the main sources of energy.

[0003] Coal mine transportation is the process of transporting coal mined from the coal seam out of the mine. The efficiency and safety of coal mine transportation directly affect the production efficiency, cost control and safety of miners. Coal mine transportation systems usually include two main links: underground transportation and ground transportation.

[0004] Among them, underground transportation needs to consider the amount of mining and lifting to ensure that the coal flow is transported at a standard speed, thereby reducing energy consumption and ensuring safety. The conventional transportation system ensures uninterrupted transportation by adding spare equipment, and then adjusts the carrying speed of the conveying equipment according to the designed theoretical coal flow speed to ensure smooth transportation; however, with the continuous deepening of the mining face, the transportation line gradually increases, and the theoretical coal flow speed cannot fully meet the transportation requirements; and with the requirements of expansion, the number of new mining faces will increase, further exacerbating the difficulty of transportation regulation. Summary of the invention

There are two coal discharge port groups of this stage and the coal discharge port groups of the same stage, and they are respectively provided with sealing Mouth plate, the transfer conveyor belt of this stage and the concentration box of this stage are respectively arranged below the two exits of the coal discharge port group of this stage, the transfer conveyor belt of the same stage and the concentration box of the same stage are respectively arranged below the two exits of the coal discharge port group of the same stage, the end of the transfer conveyor belt of this stage is arranged at the upper opening of the concentration box of the same stage, the end of the transfer conveyor belt of the same stage is arranged at the upper opening of the concentration box of the same stage, the conveyor belt of this stage is arranged below the lower end opening of the concentration box of this stage, and the conveyor belt of the same stage is arranged below the lower end opening of the concentration box of the same stage, and the conveyor belt of this stage and the conveyor belt of the same stage are separately arranged in two transport uphill tunnels.

[0014] Furthermore, the conveyor belt in the current stage section, the conveyor belt in the same stage section, the conveyor belt in the current stage, and the conveyor belt in the same stage are respectively provided with a laser emitter and a camera.

[0015] Furthermore, the laser transmitter and the camera monitor the state of the coal flow, adjust the coal flow through the transfer mechanism, and adjust the logic of the coal flow, including:

[0016] A. Coal flow monitoring:

[0017] The laser transmitter emits a laser light curtain to the conveyor belt at this stage and the conveyor belt at the same stage, and the camera collects the reflected light of the laser light curtain, so as to determine the coal flow on the conveyor belt at this stage and the conveyor belt at the same stage respectively;

[0018] B. Coal flow transfer between stages:

[0019] B1. Over-limit transportation of coal flow in this stage:

[0020] When the coal flow on the conveyor belt at this stage is greater than the over-limit threshold, the previous stage operation is carried out, and the transfer mechanism at the front end of the conveyor belt at this stage is started, so that the coal flow at the previous stage of the conveyor belt at this stage is transferred to the conveyor belt at the same stage;

[0023] C. Coal flow standard condition transportation:

[0024] When the coal flow on the conveyor belt in this stage and the conveyor belt in the same stage are both within the standard condition threshold range, there is no need to transfer the coal flow between stages, and the transfer mechanism is in a shutdown state.

[0025] Furthermore, the step B1, during the over-limit transportation of coal flow in this stage, further includes:

[0026] When the coal flow on the conveyor belt at this stage is greater than the over-limit threshold, the coal flow on the conveyor belt at the same stage should be analyzed:

[0027] If the coal flow on the conveyor belt at the same stage is transported at standard conditions, the front stage operation is carried out; if the coal flow on the conveyor belt at the same stage is not transported at standard conditions, the transport speed of the coal flow at the rear stage of the conveyor belt at the same stage needs to be increased;

[0028] At this time, the coal flow in the latter stage of the conveyor belt at the same stage should be analyzed:

[0029] If the coal flow rate of the latter stage of the conveyor belt at the same stage is greater than or equal to the over-limit threshold, it is necessary to reduce the coal flow rate of the former stage of the conveyor belt at the same stage, or even slow down the construction of the former stage of the mining operation face of the conveyor belt at the same stage;

[0034] If the coal flow on the conveyor belt at the same stage is not at the minimum carrying limit, the previous stage operation is carried out.

[0035] Furthermore, the collected value A of the coal flow on the conveyor belt in this stage i ,get:

[0036] The theoretical value of coal flow on the conveyor belt at this stage is X i , is: X i =X i-1 +A i ,

[0037] The collected value B of the coal flow on the conveyor belt in the same stage section i ,get:

[0038] Theoretical value Y of coal flow on the conveyor belt at the same stage i , is: Y i =Y i-1 +B i ,

[0039] Where: i∈N + .

[0040] Furthermore, the collected value X of the coal flow on the conveyor belt at this stage j and the theoretical value X of the coal flow on the conveyor belt at this stage i By comparison, we get: M = X i -X j ,

[0041] If M>0, the carrying speed of the coal flow of the conveyor belt at this stage should be reduced; if M<0, the carrying speed of the coal flow of the conveyor belt at this stage should be increased;

[0042] The collected value Y of the coal flow on the conveyor belt at the same stage j and the theoretical value Y of coal flow on the conveyor belt at the same stage i By comparison, we get: N = Y i -Y j ,

[0043] If N>0, the carrying speed of the coal flow on the conveyor belt at the same stage should be reduced. If N<0, the carrying speed of the coal flow on the conveyor belt at the same stage should be increased.

[0044] Furthermore, the conveyor belt in this stage and the conveyor belt in the same stage are respectively carried and speed-regulated by frequency converters;

[0050] Furthermore, the collected value X of the coal flow on the conveyor belt at this stage j , the collected value Y of the coal flow on the conveyor belt at the same stage j ,get:

[0051] The difference D between the coal flow on the conveyor belt at this stage and the conveyor belt at the same stage is: D = X j -Y j ,

[0052] If D>D0, start the transfer mechanism to transfer the coal flow from the conveyor belt at this stage to the conveyor belt at the same stage.

[0053] If D<D0, start the transfer mechanism to transfer the coal flow from the conveyor belt in the same stage to the conveyor belt in this stage.

[0054] Where: D0 is the trigger threshold for the transfer mechanism to start.

[0075] When the coal flow on the conveyor belt 216 at this stage is greater than the over-limit threshold, the coal flow on the conveyor belt 226 at the same stage should be analyzed:

[0076] If the coal flow on the conveyor belt 226 of the same stage is transported at the standard condition, the previous stage operation is carried out, and the transfer mechanism at the front end of the conveyor belt 216 of the current stage is started, so that the previous stage coal flow of the conveyor belt 216 of the current stage is transferred to the conveyor belt 226 of the same stage;

[0077] If the coal flow on the conveyor belt 226 of the same stage is not carried at the standard condition, it is necessary to increase the carrying speed of the coal flow of the latter stage of the conveyor belt 226 of the same stage;
