Description

Technical Field

[0001] The present invention belongs to the technical field of coal mining, and in particular relates to a system and method for collaborative detection of adjacent boreholes in a goaf area of an open-pit coal mine. Background Art

[0002] Major geological hazards in open-pit coal mines include soil slope instability, rock slope collapse, debris flows caused by surface water flow, subsidence in unknown goafs, and spontaneous combustion of residual coal seams. Open-pit coal mine goafs refer to historical shallow goafs, abandoned tunnels, and irregular cavities. These goafs are prone to causing surface collapse, slope instability, and equipment damage, posing a threat to production safety.

[0003] Accurately detecting the three-dimensional shape of goaf areas before overburden stripping is crucial for coal seam mining design. However, this is often difficult due to complex geological conditions and the disordered spatial distribution of goaf areas. Existing detection techniques are limited by factors such as resolution, depth, and geological interference, making it difficult to obtain effective goaf detection data. Therefore, there is an urgent need to explore efficient, high-precision, and comprehensive detection methods. Summary of the Invention

[0024] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] The inventors realized that there is a bottleneck in the open-pit coal mine goaf detection technology in the related art. When the mining operation continues to advance, the boundary of the goaf may expand or collapse. Static detection data represented by C-ALS (drilling type three-dimensional laser scanner) may quickly become invalid, and dynamic monitoring technology (such as InSAR, microseismic monitoring) is required. However, real-time data processing is difficult.

[0026] Geophysical exploration methods are complex and costly. For example, 3D seismic exploration or high-precision drone-mounted LiDAR equipment require significant investment, making them unaffordable for small mines. Low-cost methods, such as ground resistivity, lack precision and can easily lead to missed detections or misjudgments.

[0027] The inventors also recognized that due to the complexity of on-site conditions, open-pit coal mine goafs are often formed by historical disorderly mining and may present a complex structure with multiple layers and multiple branches, with irregular cavity shapes (such as isolated cavities, connected tunnels, etc.), resulting in blurred boundaries of the detection target. The top and bottom rock layers of the goaf may be composed of different lithologies (such as sandstone, mudstone, coal seams), and their physical properties (resistivity, wave velocity, density) vary significantly, which can easily generate false abnormal signals unrelated to the goaf. The goaf may be completely collapsed, partially filled (with water, gas, loose gangue), or completely empty. The physical properties of different filling media vary greatly, which directly affects the effectiveness of the detection method. For example, a water-filled goaf appears as a low-resistance anomaly in the resistivity method, while a cavity filled with gangue may be difficult to distinguish from the surrounding rock.

[0028] To this end, the embodiment of the present invention provides a system and method for collaboratively detecting adjacent boreholes in open-pit coal mine goafs with strong anti-interference capability and reliable detection data. The following describes the collaborative system for collaboratively detecting adjacent boreholes in open-pit coal mine goafs according to the embodiment of the present invention.

[0029] See also Figure 1 and Figure 2 The open-pit coal mine goaf 8 adjacent drilling collaborative detection system of the embodiment of the present invention includes drilling equipment, a light source component 1, a video component 3, a lifting device 4 and a data processing device 5.

[0030] The drilling equipment is used to construct detection boreholes 7 extending from the ground into the goaf 8, with multiple detection boreholes 7 spaced apart. When arranging the detection boreholes 7, the distribution of the detection boreholes 7 can be rationally planned based on the location of the goaf 8 initially detected, so as to maximize coverage of the goaf 8 that may impact subsequent mining operations. Because subsequent coordinated detection operations will require adjacent detection boreholes 7, the distance between adjacent detection boreholes 7 can be determined based on the effective range of the light source assembly 1 and the video assembly 3.

[0031] For example, the maximum distance between two adjacent detection boreholes 7 should be controlled within the effective distance in which the video component 3 can effectively capture the light source of the light source component 1, so as to judge whether the goaf 8 between the two detection boreholes 7 is connected based on the light source component 1 and the video component 3 set in the adjacent detection boreholes 7.

[0032] Light source assembly 1 is lowered through detection borehole 7 into goaf 8 to provide light. Vision assembly 3 is lowered through detection borehole 7 into goaf 8 to capture the light from light source assembly 1 and to obtain information about the extent of goaf 8 between vision assembly 3 and light source assembly 1. Light source assembly 1 and vision assembly 3 are lowered into goaf 8 through separate detection boreholes 7 spaced apart.

[0033] The lifting device 4 of the embodiment of the present invention can be a hoist 41 or a truck crane 42. The lifting device 4 is used to lift the light source assembly 1 or the video assembly 3 so as to lower the light source assembly 1 or the video assembly 3 to the goaf 8.

[0034] Light source assembly 1 can be hoisted via load-bearing cables such as steel strands 43 and lowered into goaf 8 via hoisting equipment 4. Power supply 2 for light source assembly 1 can be located on the ground, and an electrical connection between light source assembly 1 and power supply 2 is provided via a transmission cable 15, thereby providing power to light source assembly 1 and controlling its on / off operation. Transmission cable 15 can be attached to steel strands 43, so that it does not exert tension on light source assembly 1, thereby preventing breakage of transmission cable 15.

[0035] It can be understood that the effective capture range of the light source provided by the video component 3 to the light source component 1 is the maximum distance between the two detection boreholes 7 where the video component 3 and the light source component 1 are located.

[0036] In addition to determining whether the goaf 8 between two detection boreholes 7 is connected by cooperating with the light source assembly 1, the video assembly 3 can also utilize its own video function to collect data about the goaf 8 surrounding it. A data processing device 5 is connected to the video assembly 3 and analyzes and processes the information acquired by the video assembly 3. By integrating the video data of various areas acquired by multiple video assemblies 3, a three-dimensional contour model of the goaf 8 can be constructed.

[0037] The open-pit coal mine goaf 8 adjacent drilling collaborative detection system of the embodiment of the present invention realizes the detection of complex goaf 8 through the complex goaf 8 adjacent drilling collaborative detection, which can effectively reduce the safety hazards of mines, reduce the influence of factors such as the lithology of the overburden, the degree of collapse at different positions of the goaf 8, and the physical properties of the filling medium on the detection results, and can more intuitively and effectively obtain the extended boundary of the goaf 8. The obtained detection data is more reliable, which is convenient for optimizing subsequent mining plans and promoting green mine construction, with significant economic and social benefits.

[0038] The following describes a collaborative detection system for eight adjacent boreholes in an open-pit coal mine goaf according to some specific embodiments of the present invention.

[0039] See also Figure 1 and Figure 2 A collaborative detection system for eight adjacent boreholes in an open-pit coal mine goaf includes a drilling device, a light source component 1, a video component 3, a lifting device 4, and a data processing device 5.

[0040] The drilling equipment is used to construct detection boreholes 7 extending from the ground into the goaf 8, with multiple detection boreholes 7 spaced apart. When arranging the detection boreholes 7, the distribution of the detection boreholes 7 can be rationally planned based on the location of the goaf 8 initially detected, so as to maximize coverage of the goaf 8 that may impact subsequent mining operations. Because subsequent coordinated detection operations will require adjacent detection boreholes 7, the distance between adjacent detection boreholes 7 can be determined based on the effective range of the light source assembly 1 and the video assembly 3.

[0041] For example, the maximum distance between two adjacent detection boreholes 7 should be controlled within the effective distance in which the video component 3 can effectively capture the light source of the light source component 1, so as to judge whether the goaf 8 between the two detection boreholes 7 is connected based on the light source component 1 and the video component 3 set in the adjacent detection boreholes 7.

[0042] The light source assembly 1 is used to be lowered into the goaf 8 through the detection borehole 7 to provide a light source. Specifically, the light source assembly 1 includes a main body 11, a light source component 12, an outer cover 13 and a temperature sensor 14. The upper end of the main body 11 is used to connect with the lifting equipment 4. For example, an ear seat is provided at the upper end of the main body 11, and a steel strand 43 is provided on the upper plate of the lifting equipment 4, and the steel strand 43 is connected to the ear seat. A plurality of light source components 12 are provided on the main body 11 to provide light sources of different colors respectively. The plurality of light source components 12 can be arranged in sequence along the length extension direction of the main body 11. The main body 11 serves as a carrier for the light source component 12, the outer cover 13, the temperature sensor 14 and the like, and is used to install components such as the light source component 12, the outer cover 13, the temperature sensor 14 and the like on the main body 11, so that they form a whole with stable structure and performance. The outer cover 13 is mounted on the outside of the main body 11 and the light source 12. The outer cover 13 is a transparent outer cover 13. The light emitted by the light source 12 can pass through the outer cover 13. The outer cover 13 can also protect the structural components located inside it to avoid damage to the components caused by collision with the side wall of the borehole. The inner cavity of the outer cover 13 is a sealed cavity structure to prevent liquid from entering the outer cover 13. The temperature sensor 14 is provided on the main body 11 and is used to detect its circumferential temperature. The temperature sensor 14 can directly obtain its circumferential temperature parameters. When there is a natural phenomenon of the coal seam in the goaf 8, the equipment can be quickly evacuated when an abnormal temperature increase is detected to avoid damage to the equipment.

[0043] Light source 12 is a variable-frequency light source. Power supply 2 for light source assembly 1 is located above ground. Power supply 2 is connected to light source 12 via a transmission cable 15, which provides power to light source 12 and adjusts power supply parameters. The variable-frequency light source 12 can adjust its operating frequency based on power supply 2, thereby controlling the intensity of the light source. This allows for adjustments to the operating state of light source 12 based on varying operating conditions and the spacing between adjacent detection boreholes 7.

[0044] The light source component 12 includes at least an orange light source component 121, a red light source component 122, a green light source component 123 and a white light source component 124. The three colors of red, orange and green have a strong degree of distinction and are easier to be captured in the goaf, thereby improving the effect and efficiency of detection. Of course, the light source component 12 can also include a blue light source component to provide other light sources. An LED lamp can be set in the main body 11, and the color of the light source can be controlled according to demand. For example, when the light source assembly 1 is lowered, a white light source can be provided to illuminate the wall of the detection borehole 7, obtain the surrounding conditions of the wall, and detect the detection borehole 7. After the light source assembly 1 is lowered to the preset position, multi-color variable frequency lighting can be achieved by controlling the actions of different light source components 12 to meet the detection needs. According to the characteristics of different light sources or the characteristics of the combined light sources, the efficiency and effect of detection are improved, and the internal information data of the goaf 8 can be obtained more accurately.

[0045] The video assembly 3 of this embodiment of the present invention is a borehole camera. The video assembly 3 is hoisted by a lifting device 4 and lowered into a goaf 8 through a detection borehole 7 to capture the light from the light source assembly 1 and obtain information about the extension of the goaf 8 between the video assembly 3 and the light source assembly 1. The light source assembly 1 and the video assembly 3 are lowered into the goaf 8 through separate detection boreholes 7 spaced apart. The video assembly 3 is rotatable. During operation, it can precisely rotate 360 degrees, allowing for better control of the video assembly's viewing angle, facilitating the capture of the light from the light source assembly 1 and obtaining video data of the goaf 8 circumferentially around the video assembly 3.

[0046] Furthermore, the borehole camera can be further upgraded based on actual needs. For example, it can include an image magnification function, facilitating the acquisition of higher-definition video data and enabling more intuitive and effective detection of the extended contours of the goaf 8. By further upgrading the borehole camera's functionality, the ability to acquire goaf data can be improved, making it easier to integrate it with data processing equipment, thereby more effectively constructing the three-dimensional space of the goaf.

[0047] The lifting device 4 in this embodiment of the present invention can be a winch 41 or a truck crane 42. The lifting device 4 is used to lift the light source assembly 1 and the video assembly 3 so that they can be lowered into the goaf 8. For example, the appropriate lifting device 4 can be selected based on the weight of the light source assembly 1 or the video assembly 3, the model of the winch 41 at the construction site, the model of the truck crane 42, etc. In this embodiment, the light source assembly 1 is lifted using the truck crane 42, and the video assembly 3 is lifted using the winch 41.

[0048] The light source assembly 1 can be connected to the truck crane 42 via a load-bearing cable such as a steel strand 43. The truck crane 42 can be used to lower the light source assembly 1 into the goaf 8. The power supply 2 can be arranged on the ground. The light source assembly 1 and the power supply 2 are electrically connected via a transmission cable 15, thereby supplying power to the light source assembly 1 and controlling the on and off of the light source assembly 1. The transmission cable 15 can be attached to the steel strand 43. The transmission cable 15 does not exert tension on the light source assembly 1, thereby preventing the transmission cable 15 from breaking. Similarly, the video assembly 3 can be connected to the winch 41 via a load-bearing cable such as a steel strand 43. The winch 41 can be used to lower the video assembly 3 into the goaf 8.

[0049] It can be understood that the effective capture range of the light source provided by the video component 3 to the light source component 1 is the maximum distance between the two detection boreholes 7 where the video component 3 and the light source component 1 are located.

[0050] In actual applications, there are multiple light source assemblies 1 and multiple video assemblies 3, each of which is spaced apart circumferentially around the other. For example, there may be one light source assembly 1 and multiple video assemblies 3, each of which is arranged in a different detection borehole 7. The multiple video assemblies 3 can capture the light emitted by the light source assembly 1 from multiple directions, thereby determining the connectivity status of a larger area within the goaf 8 and improving detection efficiency.

[0051] In addition to determining whether the goaf 8 between two detection boreholes 7 is connected by cooperating with the light source assembly 1, the video assembly 3 can also utilize its own video function to collect data about the goaf 8 surrounding it. A data processing device 5 is located on the ground and connected to the video assembly 3. The data processing device 5 analyzes and processes the information obtained by the video assembly 3. By integrating the video data of various areas obtained by multiple video assemblies 3, a three-dimensional contour model of the goaf 8 can be constructed.

[0052] The open-pit coal mine goaf adjacent drilling collaborative detection system of the embodiment of the present invention realizes the detection of complex goaf through the collaborative detection of adjacent drilling holes in complex goaf, which can effectively reduce mine safety hazards, reduce the influence of factors such as the lithology of the overburden, the degree of collapse at different positions in the goaf, and the physical properties of the filling medium on the detection results, and can more intuitively and effectively obtain the extended boundary of the goaf. The obtained detection data is more reliable, which is convenient for optimizing subsequent mining plans and promoting green mine construction, with significant economic and social benefits.

[0053] See also Figures 1 to 3 , Figure 5 As shown, the method for collaborative detection of adjacent boreholes in open-pit coal mine goafs according to an embodiment of the present invention utilizes the above-mentioned collaborative detection system for adjacent boreholes in open-pit coal mine goafs to perform goaf detection, including: S101. Construct multiple detection boreholes on the ground toward the goaf. The detection boreholes should cover as much of the surface area above the goaf as possible, so that the goaf can be detected based on adjacent detection boreholes. If there are buildings above the goaf, making it impossible to construct detection boreholes in the area where the buildings are located, detection boreholes can be constructed circumferentially around the buildings. These circumferential detection boreholes can be used to detect the connectivity of the goaf below the buildings.

[0054] S102. Lower the light source assembly and the video component into adjacent detection boreholes until they are lowered into the goaf. During the lowering process, a lifting device such as a truck crane or a winch may be used. The depth of the light source assembly and the video component below the assembly is measured to ensure that the video component and the light source assembly are at approximately the same level.

[0055] Furthermore, multiple visual assemblies can be arranged simultaneously, with the multiple visual assemblies being arranged in multiple detection boreholes circumferentially of the detection borehole where the light source assembly is located. For example, multiple visual assemblies can be arranged in a fan-shaped pattern around the light source assembly to achieve fan-shaped detection, thereby improving detection effect and efficiency.

[0056] S103: Activate the light source assembly and ensure that the light provided by the light source assembly is visible to the vision assembly at adjacent detection boreholes. Normally, the distance between adjacent detection boreholes is within the effective capture range of the vision assembly's light source. If the distance between the light source assembly and the vision assembly's detection borehole increases due to the influence of surface buildings 6, the frequency of the light source assembly can be adjusted to improve the light quality, ensuring that the vision assembly can capture the light within this distance.

[0057] S104: Activate the video component to determine whether it has captured the light source of the light source assembly. This can be achieved by adjusting the orientation of the video component or adjusting its height within a certain range. Of course, the quality of the light source assembly can also be adjusted to improve detection efficiency.

[0058] S105: If yes, then the goaf between the video component and the light source component is connected. When the light source of the light source component is captured, it indicates that there is no obstruction between the video component and the light source component in the goaf.

[0059] Furthermore, at this time, the connectivity of the goaf in the height direction can be determined by synchronously raising or lowering the height of the light source assembly and the video assembly, thereby obtaining more effective detection data.

[0060] If not, then the goaf between the video component and the light source component is blocked. If the light source component's light source is not captured, this indicates a coal pillar, a blockage due to collapse, or an irregular roadway. In this case, the height connectivity of the goaf can be further assessed by synchronously raising or lowering the light source component and the video component to obtain more effective detection data.

[0061] S107: The video component acquires video data of the surrounding goaf through the video component and transmits it to the data processing device. The video data acquired by the video components in different detection boreholes is integrated to construct a three-dimensional model of the goaf. The video component can work not only in conjunction with the light source component, but also independently, or with the light provided by the light source component, to detect the goaf around the video component to acquire video data. By splicing the video data from different areas, a three-dimensional model of the goaf can be constructed, providing realistic feedback on the internal conditions of the goaf.

[0062] In the related technology, during the exploration process, the exploration line has been designed with detection boreholes according to the interval distance, but some boreholes are located in buildings, water bodies, slopes, etc. and cannot be constructed. Figure 1 The borehole 9 shown in FIG does not have the drilling conditions, and Figure 5 The exploration boreholes of ZK01, ZK02, ZK03, ZK04 and ZK05 are located on the same exploration line, but the surface above at least one of ZK02, ZK03 and ZK04 is not suitable for drilling due to surface buildings 6, water bodies, slopes, etc. Therefore, it will lead to the following Figure 4 As shown in the figure, a large number of areas cannot be detected, forming detection blind areas, which will cause the subsequent filling volume to be much larger than the detected three-dimensional space, affecting the safety of the subsequent construction and the stability of the formation. It can be seen that the effective detection and complete characterization of the goaf are particularly important, especially for the detection blind areas that cannot be effectively detected by related technologies (such as Figure 4 The embodiment of the present invention can utilize other borehole collaborative detection technologies on the same exploration line to overcome the problem of insufficient on-site construction conditions.

[0063] by Figure 5 Taking the example of ZK02, ZK03, and ZK04, all of which lack drilling conditions, as shown in the figure, by placing borehole televisions and multi-color variable frequency light sources (i.e., light source assemblies) in other adjacent detection boreholes ZK01 and ZK05 on the same exploration line, the connectivity of the goaf can be qualitatively determined by utilizing light source detection between adjacent boreholes. At the same time, the borehole television can be used to obtain video data of the goaf circumferentially, avoiding detection blind spots and more accurately acquiring three-dimensional spatial data of the goaf. This embodiment of the present invention can eliminate the construction work of ZK02, ZK03, and ZK04, reducing drilling work, saving over 40% of detection costs and over 60% of detection time, and achieving effective detection of the entire goaf. This solves the problems of difficult data acquisition and low detection effectiveness associated with related detection methods, reduces interference from external factors, and improves the reliability of detected data.
