Description

Technical Field

[0001] The present invention belongs to the technical field of digital processing of mine shaft and tunnel support, and specifically relates to a digital processing method, system and platform for mine shaft and tunnel support based on 3Dmine. Background Art

[0002] As an important safety measure for mine construction and continuous production, support engineering has a long construction period and large investment. The shafts and tunnels of key system projects such as ventilation, water supply and drainage, power supply and distribution, hoisting and transportation, and mining sites are distributed vertically and horizontally in and around the ore body. Various types of projects are affected by geological structure, stress, mining methods, blasting disturbance, service life and other factors, and the standards and forms of support are also varied. At present, the mechanization and automation of metal and non-metal mines are getting higher and higher, but the application of digital technology in support engineering is relatively low.

[0003] At present, the main support methods used in underground metal and non-metal mines include anchor rods, anchor cables, anchor spraying, anchor mesh spraying, pouring, metal brackets, steel arch frames, steel arch frame advanced pipe shed anchor rod support, etc. The support project has technical defects in the whole process of roof classification, support form determination, support range demarcation, section measurement, support design, quality acceptance, and engineering quantity accounting: First, the two-dimensional status map drawn in CAD through the actual measurement of the sidewall contours and top and bottom plate elevations of the shaft and tunnel is extensive in the process and technical management of the shaft and tunnel support project from design, construction, acceptance, etc. Second, the previous secondary delineation of shaft and tunnel geology failed to fully reflect the distribution of geological forms such as faults, joints, and weak intrusive bodies in the bad geological section in space, nor could it reflect the degree of damage and impact range of the bad geological section on the shaft and tunnel. The classification of the top plate is vague, and the design stage of the support project has certain abstractness and limitations, and there is a lack of guidance from design to construction. Third, although the shaft and tunnel after actual excavation are generally arched in cross section, the actual top plate sidewalls are uneven. According to the specification requirements, acceptance holes are drilled every 5m during quality acceptance. The engineering quantity calculation uses a 5m section to measure the width and height of the shaft and tunnel and take the average value. The engineering quantity is calculated by a fixed formula. The quality acceptance and engineering quantity calculation are highly subjective, and the engineering quantity deviation is large.

[0040] Specifically, in an embodiment of the present invention, the present invention provides a technical measure applicable to digital support of mine shafts and tunnels, which is implemented in sequence through the following method steps: (1) Point cloud data collection and organization: Scan the shafts and tunnels with a scanner to collect and organize the three-dimensional vectorized point cloud data of the shafts and tunnels.

[0041] (2) Three-dimensional solid model: A solid model is established based on three-dimensional vector point cloud data using 3Dmine mining software, which serves as the basis for geological modeling and three-dimensional design of support engineering.

[0042] (3) Three-dimensional geological modeling: Identify the structural occurrence of shaft and tunnel faults, layer joints, intrusive bodies, etc., identify lithology, stability, etc., and use 3Dmine mining software to establish a three-dimensional geological model of the shaft and tunnel.

[0043] (4) Roof classification and support engineering confirmation: Using the three-dimensional geological model as the main basis for roof classification, carry out roof classification for unfavorable geology and determine the support form, support range and support length of the unfavorable geological section.

[0044] (5) Three-dimensional design of support engineering: According to the support form, the support parameters such as steel mesh, anchor rods, and shotcrete are clarified to carry out three-dimensional design of support engineering. After the design is completed, the relevant design engineering quantity is obtained.

[0045] (6) Measuring the volume before support: Based on the support length, the volume of the support section before support is calculated using the 3Dmine software three-dimensional solid model of the shaft and tunnel, which serves as the basis for the subsequent engineering quantity calculation.

[0046] (7) 3D scanning of the shaft and tunnel after support and establishment of 3D solid model: Similar to the above (1)-(2).

[0047] (8) Measuring the volume of the shaft and tunnel after support: Similar to (6) above, volume measurement after support creates conditions for quality acceptance.

[0048] (9) Quality acceptance and engineering quantity accounting: 3Dmine software is used to import the three-dimensional solid model before and after the support, and cut to form the front and rear support sections. The thickness of the grouting can be measured at any section of the support section to complete the acceptance of the grouting thickness. The difference in the solid volume before and after the grouting is used to obtain the actual engineering quantity of the grouting or pouring, and the acceptance of the engineering quantity is completed.

[0049] Among them, Figure 1 As shown in the figure, the Hovermap scanner 3D scans and collects point cloud data that meets the accuracy requirements of the tunnel; the point cloud data is used to produce a digital vectorized 3D model of the shaft and tunnel before support, restoring the true shape of the shaft and tunnel, such as Figure 2 As shown in the figure; according to the actual situation on site, carry out three-dimensional geological cataloging, identify the occurrence and lithology of unfavorable geological bodies such as faults, layer joints, and intrusions, and use 3Dmine software to establish a three-dimensional geological model, such as Figure 3 As shown; according to the three-dimensional geological model, determine the roof grade and clarify the support form, range and length, such as Figure 4 As shown in the figure, carry out the support segment engineering design: according to the support form and various parameters, carry out three-dimensional support design for the support segment, such as Figure 5 As shown; Volume measurement before support: Through the entity function of 3Dmine software, close both ends of the support section tunnel and measure the entity volume V1 before support, as shown Figure 6 After the support, the shaft and tunnel are 3D scanned and a 3D solid model is established, as shown in Figure 7 According to the solid model after support, the volume V2 of the shaft after support is measured after closing the solid, as shown in Figure 8 The solid before and after support is cross-sectioned and the thickness is checked, as shown in Fig. 9 After the completion acceptance, the support engineering completion drawing is sorted out, as shown in Fig.10 shown.

[0050] Preferably, the specific steps are as follows: (1) Preparation before support: Mechanical prying of the shaft and tunnel is performed before scanning to ensure the safety of construction work and the accuracy of scanning data before the start of support engineering.

[0051] (2) Use the Hovermap scanner to conduct three-dimensional scanning of the shafts and tunnels, collect the original scanning point cloud data of the required support tunnel area and ≥3 measurement control points near the tunnel, with a scanning accuracy of ≤1cm; use professional point cloud processing software to solve the original data and obtain the point cloud data in the format required for point cloud processing, and calibrate the point cloud data through the scanned measurement control points to make the scanned point cloud data consistent with the mine measurement control system, with a control point calibration accuracy of ≤5mm; delete duplicate or interfering points in the point cloud (such as noise caused by large dust, points formed by tunnel wind ducts, water pipes, cables, etc. blocking the tunnel wall), thin the point cloud data, control the distance between points to ≤5cm, and organize to obtain vectorized point cloud data that matches the mine measurement control system. Figure 1 As shown: (3) Three-dimensional solid model: The solid model is established through 3Dmine mining software based on three-dimensional vectorized point cloud data. First, the rough solid model is automatically built with point cloud data through 3Dmine mining software. Then, the solid model is continuously verified and optimized by eliminating intersecting triangle edges, reorganizing invalid triangle edges, and connecting open edges. Finally, a refined solid model that meets quality requirements is formed as the basis for geological modeling and three-dimensional design of support engineering. Figure 2 As shown: (4) Three-dimensional geological modeling: Based on the physical model and geological catalog, the structural and lithological characteristics of the shaft and tunnel faults, layer joints, intrusions, etc. are obtained. According to the spatial combination of geological principles, the strike, dip, inclination and other occurrences in a three-dimensional state are made through 3Dmine software. Finally, various elements such as structure, occurrence, and lithology are integrated to establish a three-dimensional geological model of the shaft and tunnel with spatial attributes, providing a spatial digital basis for roof classification, thereby determining a scientific and reasonable support method. Figure 3 As shown: (5) Roof classification to determine support level and support length: Based on the three-dimensional geological model, according to the roof classification specifications (there are four levels of roof: Level I roof-layer joints are well developed, the bedding joint spacing is less than 0.1m, the fault is greater than 2m, and the lithology is scattered and fragmented; Level II roof-layer joints are well developed, the bedding joint spacing is 0.1-1m, the fault is 1-2m, and the lithology is layered; Level III roof-layer joints are not developed, the bedding joint spacing is less than 2- 3m, fault 0.3-1m, rock characteristics are blocky; Grade IV roof layer - joints are extremely undeveloped, bedding and joint spacing is >3m, fault <0.3m, rock characteristics are good integrity), carry out roof classification, determine the support form of the poor geological section (Grade I roof - casting or anchor mesh spraying support, Grade II roof - anchor spraying support, Grade III roof - local anchor support, Grade IV roof - no support), and determine the support length according to the impact range of the poor geological section. Figure 4 As shown: (6) Three-dimensional design of support engineering: Carry out three-dimensional design of support engineering according to the support level, parameters, and length (taking the anchor mesh spraying support commonly used in mines as an example). The mesh design is based on the mesh parameters, and the points and point connecting lines are generated through the 3Dmine software "Solid-Solid Tool-Solid Surface Mesh"; the anchor rod design uses the software to draw the anchor rod length and anchor plate size, and draws to the mesh intersection position according to the construction angle and spacing; the spraying concrete design uses the entity scaling function to obtain the tunnel design model after support, and the final measurement summary can obtain the design engineering quantity of anchor rods, meshes, and spraying concrete. Figure 5 As shown: (7) Measure the volume before support: Use the 3Dmine software to build a three-dimensional solid model of the shaft and tunnel, and use "solid-generate open edge-closed line to generate solid-merge solid" and "solid-solid volume" to obtain the closed support section volume V1, which will serve as the base for later engineering quantity calculation, such as Figure 6 shown.
