Description

Technical Field

[0001] This invention relates to the technical field of underground coal mining, and more specifically, to a single-drum coal mining machine feed process. Background Technology

[0002] Currently, the research and development of automatic following technology for intelligent coal mining in domestic underground mines mainly focuses on double-drum coal mining processes. These processes use hydraulic supports to automatically sense the position and direction of the coal mining machine, resulting in a single operating mode. While some single-drum coal mining machines are also used, they advance from one end of the coal seam to the other, cutting away coal seams along the way. However, existing single-drum coal mining machines require manual control of multiple support channels to achieve the following motion and complete the mining operation. This method necessitates real-time human intervention, increasing labor costs.

[0003] As can be seen from the above, the existing single-drum coal mining machines have the problem of inconvenience in use. Summary of the Invention

[0004] The main objective of this invention is to provide a single-drum coal mining machine feed process to solve the problem of inconvenience in the use of existing single-drum coal mining machines.

[0005] To achieve the above objectives, according to one aspect of the present invention, a single-drum coal mining machine feed process is provided. The single-drum coal mining machine feed process includes:

[0006] A single-drum coal mining machine with an oblique cutting feed located in the middle area of ​​the coal seam is used to tunnel the upper coal seam;

[0007] The single-drum coal mining machine moves toward the end of the coal passage, and the supports in the moving area perform a follow-up support action;

[0008] The single-drum coal mining machine senses the support signal in the end area, executes the single-drum rotation and begins to move towards the end of the coal passage to tunnel the lower coal seam;

[0009] The single-drum coal mining machine senses the signal of the support in the middle area and executes the single-drum rotation to excavate the upper coal seam. The support in the area where the single-drum coal mining machine travels executes the following frame pulling action.

[0010] The single-drum coal mining machine senses the support signal in the end area, executes the single-drum rotation and begins to move towards the end of the coal passage to tunnel the lower coal seam;

[0011] The single-drum coal mining machine senses the signal of the support in the end area, and the single-drum coal mining machine moves toward the end of the coal passage. The support in the area where the single-drum coal mining machine travels performs a following and pushing action.

[0012] The single-drum coal mining machine senses the signal from the support in the middle area, and the support stops pushing the conveyor.

[0013] The single-drum coal mining machine senses the support signal in the end area and moves towards the end of the coal passage.

[0014] The single-drum coal mining machine senses the signal from the support in the middle area, and each support completes the push conveyor. The single-drum coal mining machine performs single-drum rotation and oblique cutting in the middle area of ​​the coal passage, and begins to excavate the upper coal seam.

[0015] Furthermore, before the single-drum coal mining machine, located in the middle area of ​​the coal passage, makes an oblique cutting advance to tunnel into the upper coal seam, the single-drum coal mining machine's advance process also includes moving the single-drum coal mining machine to the middle area of ​​the coal passage, starting the single-drum coal mining machine, and the single-drum coal mining machine starting to move; after the single-drum coal mining machine starts to move, the single drum of the single-drum coal mining machine is started, the single drum rotates and moves towards the upper coal seam, and the single drum stops moving after moving to the preset position, so as to achieve oblique cutting into the upper coal seam.

[0016] Furthermore, the step of the single-drum coal mining machine obliquely cutting into the upper coal seam in the middle area of ​​the coal passage also includes the single drum moving with the single-drum coal mining machine to cut the upper coal seam.

[0017] Furthermore, there are N supports. The support at the end is support No. 1, and supports No. 2, No. 3...N are set sequentially from the end to the tail. An infrared transmitter is set on the single-drum coal mining machine. Converters are set on support No. 2, support No. N / 2 and support No. N-1. Support No. 2 is the support for the end area, support No. N / 2 is the support for the middle area, and support No. N-1 is the support for the tail area.

[0018] Furthermore, during the movement of the single-drum coal mining machine, the infrared transmitter sends a signal to the converter. After receiving the signal, the converter sends a control signal back to the single-drum coal mining machine. Based on the received control signal, the single-drum coal mining machine performs the corresponding action.

[0019] Furthermore, in the step of stopping the support push in the single-drum coal mining machine and the support signal sensing in the intermediate area, the infrared transmitter of the single-drum coal mining machine sends a signal toward the N / 2 support; the converter of the N / 2 support receives the signal, the N / 2-2 support to the N / 2 support performs partial push, and the N / 2 support to the N support performs no push, so as to form an inclined area between the N / 2-2 support and the N / 2 support; the converter of the N / 2 support sends a control signal to the single-drum coal mining machine.

[0020] Furthermore, in the step of the single-drum coal mining machine receiving a control signal from the support in the end area, the single drum of the single-drum coal mining machine rotates clockwise to the lower coal seam area to remove the upper coal layer in the end area. After the upper coal layer is removed, the single drum rotates counterclockwise to the upper coal seam and then continues to rotate to the lower coal seam.

[0021] Applying the technical solution of this invention, the single-drum coal mining machine's cutting process of this application employs an oblique cutting method in the central region to remove coal seams, enabling the entire cutting process to be cyclical and thus achieving uninterrupted coal seam excavation, improving the efficiency of coal seam removal. Furthermore, this cutting process achieves automated operation. Through signal sensing between the single-drum coal mining machine and the support, when the single-drum coal mining machine reaches the receiving signal, it automatically adjusts its travel direction and the rotation of the single drum. The support also has the functions of following the machine's movement, pulling the frame, and pushing the conveyor to adjust the position of the single-drum coal mining machine, achieving automatic cutting of the next coal seam. The single-drum coal mining machine's cutting process of this application reduces manual intervention, improves the efficiency of coal seam excavation, enhances overall safety, and improves the operator's experience.

[0042] To address the inconvenience of using existing single-drum coal mining machines, this invention provides a single-drum coal mining machine feed process.

[0043] like Figure 1 As shown, the single-drum coal mining machine's feed process includes:

[0044] The single-drum coal mining machine 10, located in the middle area of ​​the coal seam, uses an oblique cutting feed to excavate the upper coal seam;

[0045] The single-drum coal mining machine 10 moves toward the end of the coal passage, and the support 20 in the moving area performs a follow-up support action;

[0046] The single-drum coal mining machine 10 senses the signal from the support 20 in the end area, performs single-drum rotation and begins to move toward the end of the coal passage to excavate the lower coal seam;

[0047] The single-drum coal mining machine 10 senses the signal with the support 20 in the middle area and performs single-drum rotation to excavate the upper coal seam. The support 20 in the area where the single-drum coal mining machine 10 travels performs a follow-up frame pulling action.

[0048] The single-drum coal mining machine 10 senses the signal from the support 20 in the end area, performs single-drum rotation and begins to move toward the end of the coal passage to excavate the lower coal seam;

[0049] The single-drum coal mining machine 10 senses the signal with the support 20 in the end area, and the single-drum coal mining machine 10 moves toward the end of the coal passage. The support 20 in the area where the single-drum coal mining machine 10 is traveling performs a following and pushing action.

[0050] The single-drum coal mining machine 10 senses the signal with the support 20 in the middle area, and the support 20 stops pushing the conveyor.

[0051] The single-drum coal mining machine 10 senses the signal with the support 20 in the end area, and moves towards the end of the coal passage.

[0052] The single-drum coal mining machine 10 senses the signal with the support 20 in the middle area, and each support 20 completes the pushing of the conveyor. The single-drum coal mining machine 10 performs single-drum rotation and oblique cutting in the middle area of ​​the coal passage to start tunneling the upper coal seam.

[0053] Specifically, the single-drum coal mining machine's cutting process of this application employs an oblique cutting method in the central region to remove coal seams, enabling the entire cutting process to be cyclical and thus achieving uninterrupted coal seam excavation, thereby improving the efficiency of coal seam removal. Furthermore, this cutting process achieves automated operation. Through signal sensing between the single-drum coal mining machine 10 and the support 20, when the single-drum coal mining machine 10 reaches the receiving signal, it automatically adjusts its travel direction and the rotation of the single drum. The support 20 has the functions of following the machine's movement and pushing the conveyor to adjust the position of the single-drum coal mining machine 10, achieving automatic cutting of the next coal seam. The single-drum coal mining machine's cutting process of this application reduces manual intervention, improves the efficiency of coal seam excavation, enhances overall safety, and improves the operator's experience.

[0054] Furthermore, the coal passage is a roadway used to allow the single-drum coal mining machine 10 to move when excavating coal seams.

[0055] In this application, the support 20 pulls the frame, which is a hydraulic support 20 that moves in position. At this time, the hydraulic support does not restrict the coal passage, that is, the direction of travel of the single-drum coal mining machine 10. The support 20 pushes the conveyor by restricting the coal passage through the action of the hydraulic support, so as to control the direction of travel of the single-drum coal mining machine 10.

[0056] In this embodiment, multiple supports 20 are provided, and multiple supports 20 are set in the coal passage. During the pushing process, multiple supports 20 restrict the direction of travel of the single-drum coal mining machine 10 in the coal passage through baffles.

[0057] It should be noted that the single-drum coal mining machine 10 travels in the area between the support 20 and the coal seam. Driven by the drive unit, the single-drum coal mining machine 10 moves along the length of the coal passage. The support 20 is set on the side of the single-drum coal mining machine 10 and restricts the movable area of ​​the coal passage by pushing the baffle, so that the single-drum coal mining machine 10 can move along the inclined area formed by the push of the support 20, i.e., the inclined surface, thereby realizing the oblique cutting into the coal seam in the middle area of ​​the new coal seam to the upper coal seam.

[0058] In this embodiment, before the step of the single-drum coal mining machine 10 obliquely cutting into the upper coal seam in the middle area of ​​the coal passage, the single-drum coal mining machine cutting process further includes:

[0059] Move the single-drum coal mining machine 10 to the middle area of ​​the coal passage, start the single-drum coal mining machine 10, and the single-drum coal mining machine 10 begins to move.

[0060] After the single-drum coal mining machine 10 starts moving, the single drum of the single-drum coal mining machine 10 is activated. The single drum rotates and moves toward the upper coal seam. After the single drum moves to the preset position, it stops moving to achieve oblique cutting into the upper coal seam.

[0061] When mining coal for the first time, the single-drum coal mining machine 10 needs to be moved to the middle area of ​​the coal passage, and the oblique cutting is achieved by controlling the forward movement of the single-drum coal mining machine 10 and the rotation of the rotating arm connected to the single drum.

[0062] In this embodiment, the preset position is any position where the single drum rotates to a position between 45° and 60° where the angle between the rotating arm and the reverse direction of the single drum coal mining machine 10 is 45°-60°.

[0063] In this embodiment, the step of the single-drum coal mining machine 10, located in the middle area of ​​the coal passage, making oblique cutting cuts to advance into the upper coal seam further includes: the single drum following the single-drum coal mining machine 10 to cut the upper coal seam.

[0064] In this embodiment, the single-drum coal mining machine 10 has a preset length L, wherein the length of L is the same as the length formed between three adjacent supports 20.

[0065] Furthermore, there are N supports 20. The support 20 at the end is support 1. Supports 2, 3, ... N are arranged sequentially from the end to the tail. An infrared transmitter is installed on the single-drum coal mining machine 10. Converters are installed on support 2, support N / 2 and support N-1. Support 2 is the support 20 in the end area, support N / 2 is the support 20 in the middle area, and support N-1 is the support 20 in the tail area.

[0066] In this embodiment, during the movement of the single-drum coal mining machine 10, the infrared transmitter sends a signal to the converter. After receiving the signal, the converter sends a control signal back to the single-drum coal mining machine 10. The single-drum coal mining machine 10 performs the corresponding action according to the received control signal.

[0067] The step of stopping the pusher 20 when the single-drum coal mining machine 10 detects a signal between itself and the support 20 in the intermediate area includes:

[0068] The infrared transmitter of the single-drum coal mining machine 10 sends a signal toward the N / 2 support;

[0069] The converter of bracket N / 2 receives the signal, bracket N / 2-2 to bracket N / 2 performs partial push-slide, bracket N / 2 to bracket N performs no push-slide, so as to form an inclined area between bracket N / 2-2 to bracket N / 2+1;

[0070] The converter of support N / 2 sends control signals to the single-drum coal mining machine 10.

[0071] In the step where the single-drum coal mining machine 10 and the support 20 in the end area receive signal sensing, the single drum is rotated and begins to move towards the end of the coal passage to excavate the lower coal seam,

[0072] The single-drum coal mining machine 10 receives a control signal fed back from the support 20 in the end area;

[0073] The single drum of the single-drum coal mining machine 10 rotates clockwise to the lower coal seam area to remove the upper coal seam in the end area;

[0074] After the upper coal seam is removed, the single drum rotates counterclockwise to the upper coal seam and then continues to rotate to the lower coal seam.

[0075] In this case, the end of the coal passage is to the left and the end is to the right. During the process of the single-drum coal mining machine 10 excavating the upper coal seam, the single drum is on the right side, that is, in the right top area. When the single-drum coal mining machine 10 travels to the end area, the single drum rotates from the right top to the left bottom, so as to cut off the upper coal layer in the end area. After that, the single drum rotates counterclockwise to the right bottom to excavate the lower coal seam.

[0076] When the single-drum coal mining machine 10 and the support 20 in the middle area are signal-sensing, the single drum is rotated to excavate the upper coal seam. During the follow-up pulling action of the support 20 in the traveling area of ​​the single-drum coal mining machine 10, the single drum rotates to the top right to excavate the upper coal seam.

[0077] The single-drum coal mining machine 10 and the support 20 in the end area are signal-sensing, and the single drum is rotated and begins to move toward the end of the coal passage to tunnel into the lower coal seam. The single drum rotates to the right bottom.

[0078] The single-drum coal mining machine 10 in this application is a top-and-bottom single-arm coal mining machine.

[0079] In this embodiment, as Figures 2 to 14 In the specific embodiment shown, 28 supports 20 are arranged along the length of the coal passage, of which supports 1, 2 and 3 are support supports for the end area, supports 26, 27 and 28 are support supports for the end area, and converters are arranged on supports 2, 14 and 27.

[0080] In Phase 1, the single-drum coal mining machine 10 moves towards the end in the middle area. The single drum starts to rotate and make oblique cutting from above the rear support 14. Specifically, the oblique cutting is completed above the support 11, and the upper coal seam is cut.

[0081] Phase 2: The single-drum coal mining machine 10 moves towards the end. Supports 11, 10, 9, 8, 7, 6, 5, and 4 begin to follow the machine and pull the supports in sequence. The single-drum coal mining machine 10 stops above supports 1, 2, and 3, and supports 1, 2, and 3 do not pull the supports. The single-drum coal mining machine 10 receives the feedback control signal from support 2 and begins to rotate the single drum. The single drum rotates clockwise from the top right to the bottom left. The single-drum coal mining machine 10 then begins to move towards the end, and the single drum rotates counterclockwise to the bottom right.

[0082] In stage 3, when the single-drum coal mining machine 10 moves above support 11, it receives the feedback control signal from support 14. Supports 1, 2 and 3 complete the pull-out, and the single drum rotates counterclockwise to the top right. The single-drum coal mining machine 10 then begins to cut the upper coal seam towards the end.

[0083] In stage 4, the single-drum coal mining machine 10 moves towards the end, and supports 12-23 are pulled up one after another. The single-drum coal mining machine 10 moves above supports 26, 27 and 28, and supports 26, 27 and 28 are not pulled up. The single-drum coal mining machine 10 receives the feedback control signal from the converter of support 27, and the single drum rotates to the bottom right.

[0084] In stage 5, the single-drum coal mining machine 10 moves towards the end. When it passes support 14, the single-drum coal mining machine 10 receives the feedback control signal from support 14, and supports 26, 27 and 28 pull the frame.

[0085] In stage 6, the single-drum coal mining machine 10 moves to the end, with the single drum always remaining at the bottom.

[0086] In stage 7, the single-drum coal mining machine 10 moves from the head to the tail, and supports 1 to 11 perform a following push action to limit the distance between the coal seam and the single-drum coal mining machine 10, so that the baffle moves towards the coal seam side; supports 12 to 15 form an inclined area, supports 16 to 28 do not push, and the single drum is at the bottom right.

[0087] In stage 8, the single-drum coal mining machine 10 moves from the tail end toward the middle area. The single-drum coal mining machine 10 passes through the inclined area to receive the feedback control signal of support 14 when it reaches support 14. The single drum rotates to the top right to start the oblique cutting. Supports 16 to 28 perform the push-slide, which is the same as the state in stage 1.

[0088] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0089] Applying the technical solution of this invention, the single-drum coal mining machine's cutting process of this application employs an oblique cutting method in the middle region to remove coal seams, enabling the entire cutting process to be cyclical and thus achieving uninterrupted coal seam excavation, improving the efficiency of coal seam removal. Furthermore, this cutting process achieves automated operation. Through signal sensing between the single-drum coal mining machine 10 and the support 20, when the single-drum coal mining machine 10 reaches the receiving signal, it automatically adjusts its travel direction and the rotation of the single drum. The support 20 has the functions of following the machine's movement and pushing the conveyor to adjust the position of the single-drum coal mining machine 10, achieving automatic cutting of the next coal seam. The single-drum coal mining machine's cutting process of this application reduces manual intervention, improves the efficiency of coal seam excavation, enhances overall safety, and improves the operator's experience.
