[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0030] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] In the production of coal mine tunnel excavation, support operations need to be carried out in a timely manner. Support workers support the cross-section (main side, secondary side, and roof) based on paper CAD support design drawings. During the support process, paper-based viewing and recording greatly reduces work efficiency; after the support is completed, the acceptance results are recorded in paper form, which is greatly affected by human subjective factors, and it is impossible to record information by comparing the specific anchor rods and cables in the drawings. The information is difficult to save and the accuracy is low. Based on this, the embodiment of the present application provides a coal mine excavation support visualization method, equipment, and computer-readable storage medium, so that only a small amount of data needs to be input to generate a cross-section support design drawing, thereby improving the processing efficiency of support data; and by visualizing the cross-section support design drawing, the viewing convenience of the support process is improved, making the support process more intuitive and vivid.

[0033] Example 1

[0034] An embodiment of the present application provides a method for visualizing coal mine excavation support, which is applied to a first user terminal, and the first user terminal may be a PC terminal that supports user operations.

[0035] See also Figure 1 As shown, the coal mine excavation support visualization method includes the following steps:

[0036] Step S102, determining the number of support rows based on the section length and the support row spacing.

[0037] Coal mine excavation support includes main support, auxiliary support and roof support. After recognizing the row spacing (in meters, M) input by the user, the total number of support rows can be calculated based on the section length and the support row spacing. In one embodiment, the rule for calculating the number of rows is: the total number of rows to be supported = section length / support row spacing + 1. When calculating the number of rows to be supported, if the calculation result is a non-integer, it can be rounded up or down, or the number of rows to be supported can be manually adjusted according to actual needs.

[0038] Step S104: based on the support information of any support platoon input by the user, determine the support information of other support platoons.

[0039] For the main support and auxiliary support, the support information includes the pre-configured serial number, number, support type, and one or more of the following information: distance from the top plate or the previous number, specification model, exposed length, anchor model, anchor quantity, torque force, and pull-out force.

[0040] Among them, the sequence number is used to represent the row number, and the number is used to represent the basic information of the section, including the section type (main section or auxiliary section), support type identification, support row number identification and anchor serial number identification. Among them, the numbering rules of the main section are as follows: ZB represents the main section, MG represents the anchor, -1 represents the row number, and the last -1 represents the number of the anchor in the row. ZB-MG-1-1 represents the first main section anchor in the first row; the support type is anchor. The auxiliary section support information is similar to the main section, except that the numbering rules are inconsistent. The auxiliary section numbering rules are as follows: FB represents the main section, MG represents the anchor, -1 represents the row number, and the last -1 represents the number of the anchor in the row. ZB-FG-1-1 represents the first auxiliary section anchor in the first row. Each support information is operational information and can be determined by the user inputting specific values, such as the input value of the distance from the top plate or the previous number (in millimeters), specification model (text input), exposed length (digital input, in millimeters), anchor information (text input), anchor quantity (digital input), torque (numerical input, in Newton-meters (N·M)), and pull-out force (numerical input, in kilonewtons, KN).

[0041] For ease of understanding, Figure 2It shows the overall schematic diagram of the support information of the main support and the main support design diagram. Figure 3 An overall schematic diagram of support information of a secondary support and a design drawing of the secondary support is shown.

[0042] For the main support and the secondary support, the user can input the support information of the first row. In actual application, the user can also input the support information of any row, which can be adjusted according to the actual situation. Here, the support information of the first row is preferably used as an example for explanation. After the support information of the first row is determined, in addition to the pre-configured sequence number, number and support type, the support information of other rows can be directly generated based on the support information of the first row.

[0043] For roof support, the support information includes a pre-configured serial number and one or more of the following information: support type, row number, distance from the main support or the previous number, specification model, exposed length, anchor model, number of anchors, torque, and pull-out force. Since the roof support design is different from the main support and the secondary support, there is a mix of anchor rods and anchor cables in the roof support. There may be one row of anchor rods and one row of anchor cables within a distance range, so the support type of the roof includes anchor rods or anchor cables. The row number may include row A, row B, etc. In the same row, if it is row A, the distance from row B to row A is automatically displayed as empty. If it is row B, the distance from row B to row A needs to be entered. Figure 4 (a) shows a schematic diagram of a roof support design drawing, and Figure 4 (b) shows a schematic diagram of a single-row roof support design drawing.

[0044] For roof support, after the support information of the first row is determined, in addition to the pre-configured serial numbers, the support information of other rows can be directly generated based on the support information of the first row.

[0045] Furthermore, after the support information is determined, in order to improve operability and adaptability, the support information may be modified and / or deleted in response to a trigger operation on the editing control.

[0046] In one example, when the support information needs to be modified, the correction information is input into the support information corresponding to the first row, and after the modification is completed, the other support information corresponding to the second row is also corrected accordingly.

[0047] In another example, assuming that the number of rows to be supported is determined to be 5 according to the input support row spacing, after receiving the support information of the first row, the support information of rows 2 to 5 is automatically generated. If there is no need to support the fourth row, the corresponding delete control of the fourth row is triggered, the support information of the fourth row is deleted, and the sequence number and serial number of the fifth row are automatically reordered.

[0048] In another example, a new row may be added to a certain row to increase the number of rows to be supported.

[0049] Step S106, generating a cross-section support design drawing based on all support information.

[0050] The above support information may include the actual distance between the support point in the support row and the reference position and the adjacent support point, and the reference position is also the position corresponding to the top plate or the main support. Preferably, after the cross-section support design drawing is generated, the actual distance can be further marked in the cross-section support design drawing: for the main support, the anchor spacing and the anchor-top plate spacing are marked in the cross-section support design drawing; for the top plate support, the anchor-top plate spacing, the anchor cable-top plate spacing, the anchor spacing, the anchor cable spacing, and the anchor cable spacing are marked in the cross-section support design drawing.

[0051] In one embodiment, the canvas above the graphical user interface of the first user terminal automatically generates a diagram of the design drawing, and marks the distance between the anchor rod and the top plate, the distance between the anchor cable and the top plate, the distance between the anchor rod and the spacing, the distance between the anchor rod and the anchor cable, and the distance between the anchor cable and the anchor cable. In one embodiment, the pixel distance can be determined according to the support row spacing, the actual distance, and the ratio of the pixel distance to the actual distance, and the position of each support point on the cross-sectional support design drawing can be determined according to the pixel distance to generate the cross-sectional support design drawing, wherein the calculation rule of the pixel distance can be: the pixel spacing between anchor rods = the ratio of each pixel to the actual distance * the actual distance between each anchor rod, the ratio of each pixel to the actual distance = the cross-sectional height / the total height of the canvas pixels.

[0052] Furthermore, after the cross-section support design drawing is generated, a support task can be further generated based on the cross-section support design drawing and the cross-section information to be supported; wherein the cross-section information to be supported is used to characterize the cross-section information bound to the support process. The support task can also be further sent to the second user terminal so that the user using the second user terminal is informed of the support task and performs support, acceptance and other tasks on site.

[0053] Furthermore, after the support acceptance is completed, the display effect of the support point in the cross-section support design drawing can be updated according to the support point acceptance result submitted by the user. The display effect can distinguish the acceptance results through color identification. For example, the qualified acceptance can be represented by a green mark, and the unqualified acceptance can be represented by a red mark. In actual applications, other color identifications can also be used to distinguish and represent the acceptance results, which is not specifically limited here.

[0054] Example 2

[0055] The embodiment of the present application provides a method for visualizing coal mine excavation support, which is applied to a second user terminal, which is an APP terminal. Figure 5 As shown, the coal mine excavation support visualization method includes the following steps:

[0056] Step S502, receiving a support task issued by a first user terminal; the support task is generated based on a cross-section support design drawing and information about the cross-section to be supported; the cross-section support design drawing is generated by the first user terminal in communication connection with the second user terminal based on the support information;

[0057] Step S504: Generate acceptance information based on the support task.

[0058] Step S506, after the acceptance information is qualified, the status information corresponding to the acceptance information is updated to qualified, and the cross-section support design drawing is displayed. The status information includes the accepted status and the unaccepted status, and the accepted status can further include the accepted status and the unaccepted status.

[0059] In one embodiment, the above acceptance information can be represented by graphical symbols for anchor rods or anchor cables, such as blank circles for anchor rods or anchor cables that have not been accepted, and solid circles for accepted ones. Solid circles can also be represented by different colors to represent the acceptance status of qualified and unqualified acceptance. Figure 6 , Figure 7 and Figure 8 The following is a schematic diagram of the acceptance of the main side, the auxiliary side and the top plate. The solid circle uses a grayscale circle to represent the qualified acceptance state, and the black circle uses a black circle to represent the unqualified acceptance state. In practical applications, other shapes and colors can also be used to illustrate different states, which is only an example here and is not specifically limited.

[0060] The second user terminal is mainly used for supporting acceptance at the coal mine excavation support site. In order to further improve the viewing effect of the acceptance results, in an optional implementation, the second user terminal can be further used for:

[0061] In response to the user's sliding operation on the top of the support task display interface, the currently displayed support design drawing is switched; or, in response to the user's sliding operation on the currently displayed support design drawing, the support information contained in the support design drawing is displayed.

[0062] In actual application, when the shift task is issued, after checking the section, the section support bound to the permanent support process will be issued to the specific shift; when assisting in the command of permanent support, you can view the support acceptance standards, and swipe left and right on the top to switch the support design drawings corresponding to the left side, right side, and top plate. Sliding left and right on the support design can display the support information of each row in pages (the main side, secondary side, and top plate support design drawings on the App are displayed in the same way as on the PC), and click on a specific single anchor rod (anchor cable) to display the support design standards.

[0063] When the permanent support has been completed and is awaiting acceptance, the inspector will inspect the single anchor rod (anchor cable). If the acceptance is qualified, the status of the anchor rod (anchor cable) will be set to green. If the acceptance is unqualified, the status of the anchor rod (anchor cable) will be set to red. Click again to view the acceptance results of the accepted anchor rod (anchor cable).

[0064] The embodiment of the present application can realize the functions of support acceptance and acceptance information update and viewing through the APP, thereby improving the convenience of acceptance data processing.

[0065] Example 3

[0066] The present application embodiment provides a specific method for visualizing coal mine excavation support, which is applied to a first user terminal and a second user terminal. Fig. 9 As shown, the design drawing is generated and the task is issued through the PC, and the support acceptance is carried out through the APP. For details, please refer to the above-mentioned embodiment, which will not be repeated here.

[0067] In summary, this application automatically designs, calculates and generates support design drawings, and the support standards and support results can be viewed simultaneously and intuitively on the PC and APP sides, realizing the transformation from paper CAD design drawings to information-based design drawings. On the surface, it is a change in the recording medium, but in essence it is a key step for coal mine support to enter informationization and standardization, which greatly improves the work efficiency of support workers and is more convenient during maintenance and inquiry.
