Description

Technical Field

[0001] This invention relates to the field of coal mine safety mining technology, specifically to a coal mine rockburst roadway energy storage support and anti-rockburst system and method. Background Technology

[0002] With the increasing depth of coal mining, especially during the excavation of roadways prone to rock bursts, the stress during the excavation of rock burst working faces undergoes drastic adjustments, generating coal bursts of varying scales. When a coal burst occurs, the elastic energy stored in the coal and rock mass is released instantaneously, forming a high-intensity impact stress wave. This causes the support structure to bear instantaneous dynamic loads far exceeding static loads, directly leading to fracture, bending, or overall instability of the support structure. Among related technologies, traditional anchor bolt support structures, although possessing a certain degree of impact resistance, still struggle to meet the safety requirements of mines under rock burst conditions. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose an energy storage support and anti-rockburst system and method for coal mine rockburst roadways. The energy storage support and power generation structure adopted by the coal mine rockburst roadway energy storage support and anti-rockburst system can not only resist the impact energy generated by the coal and rock mass, but also capture the energy released by the coal and rock mass and convert it into electrical energy for storage and utilization.

[0005] The coal mine rockburst roadway energy storage support and anti-rockburst system according to an embodiment of the present invention includes: Anchoring mesh, which is laid on the tunnel wall; An anchoring assembly, comprising a plurality of anchors, wherein the plurality of anchors are spaced apart on the roadway wall along the longitudinal section of the roadway.

The nut, the tray, and the power generator are sequentially fitted onto the anchor rod. The power generator extends in the same direction as the anchor rod. The power generator is used to capture the energy released by the coal and rock mass and convert it into electrical energy. There are multiple anchoring components, which are arranged at intervals along the extension direction of the roadway.

[0020] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] like Figures 1-3 As shown in the accompanying drawings, the coal mine rockburst roadway energy storage support and anti-rockburst system of this invention is described below according to the accompanying drawings.

[0022] The coal mine rockburst roadway energy storage support and anti-rockburst system of this invention includes an anchoring mesh and an anchoring component 1.

[0023] Anchoring mesh is laid on the roadway wall. Anchoring assembly 1 includes multiple anchors 11. On the longitudinal section of the roadway, multiple anchors 11 are spaced apart on the roadway wall. Anchor 11 includes anchor rod 111, nut 112, tray 113 and power generation part 114. Anchor rod 111 is used to insert into anchor holes on the roadway wall. Nut 112, tray 113 and power generation part 114 are sequentially fitted onto anchor rod 111. The extension direction of power generation part 114 is consistent with the extension direction of anchor rod 111. Power generation part 114 is used to capture the energy released by coal and rock mass and convert it into electrical energy. There are multiple anchoring assemblies 1, which are spaced apart along the extension direction of the roadway.

[0024] Specifically, such as Figure 1 and Figure 2As shown, the anchoring mesh is directly laid on the tunnel wall 100 to form a basic protective layer. Anchor bolts 111 are inserted into anchor holes in the tunnel wall to provide basic fixation. After the generator part 114 is fitted onto the anchor bolt 111, a tray 113 and a nut 112 are sequentially fitted on for fixation, completing the installation of the anchoring assembly 1. The arrangement of multiple anchoring assemblies 1 can be determined according to the actual tunnel conditions to ensure the overall strength of the support structure. For example, in the tunnel's extension direction, the number of anchors 11 in the multiple anchoring assemblies 1 can be arranged in a "five-four-five" pattern to ensure the support effect.

[0025] Understandably, the anchor bolt 111, inserted into the anchor hole in the roadway wall, can penetrate deep into the coal and rock mass, providing reliable anchoring force and connecting the coal and rock mass on the roadway wall with the deeper, stable coal and rock mass, thereby enhancing the load-bearing capacity of the roadway wall. Under the tightening action of the nut 112, the tray 113 evenly transmits the anchoring force of the anchor bolt 111 to the roadway wall and the anchoring mesh, further improving the support effect.

[0026] When a rock burst occurs, the elastic energy stored within the coal and rock mass is released instantaneously, forming high-intensity impact energy. The power generation unit 114 can capture this energy and convert it into electrical energy. This not only achieves effective utilization of the impact energy and reduces damage to the support structure, but also allows the converted electrical energy to be used for other equipment within the roadway, such as lighting and monitoring, thus improving energy utilization efficiency.

[0027] It should be noted that the power generation unit 114 can employ piezoelectric power generation materials (such as piezoelectric ceramics, which can convert impact pressure into electrical energy), electrostatic / capacitive energy harvesting systems (i.e., changing the spacing or area of ​​capacitor plates through mechanical force to cause charge redistribution), or flexible power generation technologies (such as flexible magnetoelectric composite materials, which change the magnetization state through stress and then generate electricity through coil induction). In other words, the energy storage support and anti-impact system for coal mine rockburst roadways in this embodiment of the invention adopts energy storage support and power generation measures that not only resist the impact energy generated by the coal and rock mass but also simultaneously capture the energy released by the coal and rock mass and convert it into electrical energy for storage or utilization.

[0028] In other words, the coal mine rockburst roadway energy storage support and anti-rockburst system of this embodiment can capture the energy released by the coal and rock mass under rockburst while providing support structure, and convert it into electrical energy using the power generation unit 114. This not only improves energy utilization efficiency, but also helps in monitoring and early warning.

[0029] In other embodiments, such as Figure 3As shown, the power generation unit 114 includes a first power generation component 114a and a second power generation component 114b. The first power generation component 114a is placed between the tray 113 and the wall 100 of the tunnel, and the second power generation component 114b is placed inside the anchor hole.

[0030] It is understandable that, such as Figure 3 As shown, the first power generator 114a is fitted onto the anchor bolt 111 and positioned between the tray 113 and the tunnel wall 100. This allows the first power generator 114a to deform under the pressure of the tunnel wall 100 and the tray 113 when an impact occurs in the tunnel, generating a corresponding electrical charge. Similarly, the second power generator 114b is fitted onto the anchor bolt 111 placed inside the anchor hole. This allows the second power generator 114b to capture energy at a deeper location when the stress wave generated by the impact pressure propagates within the coal and rock mass, thus expanding the energy capture range.

[0031] In other words, the first power generator 114a is located on the outside of the tunnel wall, while the second power generator 114b is located inside the anchor hole. These two components capture the energy generated by the rockburst from different locations and depths, achieving comprehensive and multi-layered capture of the impact energy. This synergistic effect greatly improves the energy capture efficiency of the power generator 114, enabling more energy to be converted into electrical energy and improving energy recovery and utilization.

[0032] Furthermore, both the first power generator 114a and the second power generator 114b, while capturing energy, also reinforce the roadway's support structure. Specifically, the first power generator 114a and the second power generator 114b enhance the stability of the support system from the roadway wall and the coal and rock mass, respectively, enabling the support system to better resist damage under rockburst conditions and improving the reliability and safety of the entire coal mine's rockburst-prone roadway energy storage support and anti-rockburst system. In some embodiments, the coal mine rockburst roadway energy storage support and anti-rockburst system of the present invention further includes an energy storage component connected to the power generation unit 114 for storing the electrical energy converted by the power generation unit 114.

[0033] Understandably, the energy release from a rock burst is instantaneous, and the electrical energy converted by the generator 114 is also instantaneous. The energy storage component can store this instantaneously generated electrical energy, preventing waste due to unavailability. This resolves the contradiction between the instantaneity of energy generation and the continuity of actual use, ensuring that the energy released by the rock burst can be effectively utilized when needed.

[0034] Therefore, the electrical energy stored in the energy storage components can provide power support for other equipment in the mine roadway when they need electricity. For example, lighting equipment and monitoring equipment in the roadway can use the electrical energy stored in the energy storage components. This not only improves energy utilization efficiency but also reduces dependence on external power supply systems. In the event of an external power supply failure, the electrical energy stored in the energy storage components can ensure the normal operation of critical equipment in the roadway, thereby improving the safety and reliability of the mine.

[0035] In some embodiments, the energy storage component includes an early warning device for detecting the amount of power generated by the power generation unit 114. If the amount of power generated by the power generation unit 114 exceeds a preset value, the early warning device issues a warning signal.

[0036] Understandably, the energy generated by a rockburst is closely related to the power generation of generator 114. When the power generation of generator 114 exceeds the preset value, it means that the intensity of the rockburst is relatively large, which may pose a serious threat to the roadway support structure and mine safety. The warning device issues a warning signal to promptly remind mine workers of the danger of rockburst, so that they can take corresponding protective measures, such as evacuating the danger zone and strengthening support inspections, thereby ensuring the safety of personnel.

[0037] In other words, high-intensity rock bursts can easily cause the support structure to fracture, bend, or become unstable. By using early warning devices to monitor and alert on power generation in real time, workers can take reinforcement measures in advance before the support structure is seriously damaged, thus avoiding damage to the support structure and ensuring the stability and safety of the roadway.

[0038] In some embodiments, the plurality of anchors 11 are divided into first anchors 11a and second anchors 11b. The length of the anchor rod 111 of the first anchor 11a is less than the length of the anchor rod 111 of the second anchor 11b, and at most one second anchor 11b is provided between two adjacent first anchors 11a.

[0039] It is understandable that, such as Figure 1 and Figure 2 As shown, the anchor bolt 111 of the first anchor 11a is shorter and mainly anchors the shallow coal and rock mass of the roadway wall; the anchor bolt 111 of the second anchor 11b is longer and can penetrate deeper into the coal and rock mass. This combination of long and short anchor bolts 111 allows for anchoring of coal and rock masses at different depths on the roadway wall, making the shallow and deep coal and rock masses form a unified whole to jointly resist the effects of rockburst. This effectively improves the overall stability of the roadway wall, reduces the spalling of shallow coal and rock masses and the displacement of deep coal and rock masses, and enhances the reliability of the support system.

[0040] In other words, during a rockburst, anchor bolts 111 of different lengths can distribute stress to coal and rock masses at different depths. The shorter first anchor bolt 11a 111 initially bears a portion of the impact stress and transfers it to the shallow coal and rock mass; the longer second anchor bolt 11b 111 further transfers the stress to the deeper, more stable coal and rock mass. This stress dispersion and transfer method avoids stress concentration at a certain depth in the coal and rock mass, reduces the risk of failure of the support structure due to stress concentration, and improves the impact resistance of the support system.

[0041] The following describes a method for preventing rockburst in coal mine roadways using energy storage support according to an embodiment of the present invention.

[0042] The method for energy storage support and anti-rockburst protection in coal mine roadways according to embodiments of the present invention, wherein the energy storage support and anti-rockburst protection system for coal mine roadways utilizes any one of the energy storage support and anti-rockburst protection systems described in the above embodiments, includes the following steps: S1. Based on the geology of the tunnel and the mining conditions, select the anchor bolt 111 component.

[0043] It is understandable that different geological conditions in roadways, such as the hardness, integrity, and degree of joint and fracture development of the coal and rock mass, will place different performance requirements on the anchor bolt 111 components. For example, in areas where the coal and rock mass is relatively soft and fractured, it may be necessary to select anchor bolt 111 components with stronger anchoring force and longer length to ensure that they can penetrate deep into the stable coal and rock mass to provide reliable anchoring. In contrast, in areas where the coal and rock mass is relatively intact and hard, relatively short anchor bolt 111 components with lower anchoring force requirements can be selected, thus meeting the support needs while reducing costs.

[0044] Mining conditions include mining depth, mining method, and mining speed. As mining depth increases, the in-situ stress on the roadway increases, as does the likelihood and intensity of rockbursts. Therefore, it is necessary to select anchor bolt 111 components with higher impact resistance. Different mining methods and speeds will lead to different stress distributions and changes in the coal and rock mass surrounding the roadway, requiring the selection of appropriate anchor bolt 111 components based on the actual situation.

[0045] In other words, by selecting the anchor bolt 111 component according to the tunnel geology and mining conditions, the support system can be better adapted to the actual engineering environment, improve the support effect and reliability, and avoid support failure or cost waste caused by improper selection.

[0046] S2. Drill holes into the tunnel wall and install the anchoring agent, anchor bolt 111, generator 114, tray 113 and nut 112 in sequence.

[0047] Understandably, specialized drilling equipment is used to drill anchor holes of appropriate diameter and depth into the roadway wall. The location and spacing of these holes need to be precisely controlled according to design requirements to ensure the proper arrangement of the anchor bolt 111 assembly. Anchoring agent is placed into the anchor holes; its function is to bond the anchor bolt 111 to the surrounding coal and rock mass, providing anchoring force. During installation, it is crucial to ensure the anchoring agent fully fills the anchor holes and bonds tightly to the anchor bolt 111 and the coal and rock mass. The anchor bolt 111 is inserted into the anchor hole containing the anchoring agent, and the agent is evenly distributed by rotation or other methods. After the anchoring agent cures, the anchor bolt 111 is firmly connected to the coal and rock mass. The generator unit 114 and the tray 113 are then sequentially fitted onto the anchor bolt 111. Finally, the nut 112 is tightened, causing the tray 113 to press firmly against the generator unit 114 and the roadway wall, ensuring a tight connection between all components.

[0048] Therefore, strictly following the order of installation of each component can ensure the installation quality of the anchor bolt 111 assembly, enabling the anchor bolt 111 to effectively perform its anchoring function, while the power generation unit 114 can also be stably installed in a suitable position, preparing for subsequent energy collection and conversion.

[0049] S3. The mechanical energy generated by the coal and rock mass is collected by the power generation unit 114, and the deformation is caused by the mechanical energy to generate electrical energy.

[0050] Understandably, when a rock burst occurs, the elastic energy stored within the coal and rock mass is released instantaneously, forming a high-intensity impact stress wave, causing the coal and rock mass to vibrate and deform. The power generation unit 114 can capture this mechanical energy, for example, through internal piezoelectric materials or other energy conversion devices, causing deformation under the action of mechanical energy, thereby converting mechanical energy into electrical energy.

[0051] This energy harvesting and conversion method enables the effective utilization of rockburst energy, converting energy that might otherwise damage the support structure into usable electrical energy. This not only reduces the damage to the support structure but also provides a power source for other equipment in the tunnel, improving energy utilization efficiency.

[0052] S4. Monitor the changes in roadway support force in real time based on the power generation of the power generation unit 114.

[0053] It is understood that the power generation of the power generation unit 114 in the coal mine rockburst roadway energy storage support and anti-rockburst method of this embodiment is closely related to the stress and deformation of the coal and rock mass. When the roadway support force changes, the stress state of the coal and rock mass also changes, causing changes in the magnitude and frequency of the energy generated by the rockburst, which in turn affects the power generation of the power generation unit 114. By monitoring the power generation of the power generation unit 114 in real time, the changes in the roadway support force can be indirectly understood.

[0054] Therefore, the coal mine rockburst roadway energy storage support and anti-rockburst method of this invention can promptly detect abnormal changes in roadway support force and provide early warning of potential problems in the support structure, so as to take corresponding measures to deal with them, such as strengthening the support and adjusting mining parameters, to ensure the safety and stability of the roadway.

[0055] In some embodiments, in step S2, for the goaf roadway, an annular power generation unit 114 is arranged in the anchor hole in the roof of the lateral goaf area.

[0056] Understandably, the stress situation of the roof in the lateral goaf of the goaf roadway is quite complex. The existence of the goaf causes the roof to lose some support, and under the action of rock pressure, the stress distribution on the roof is uneven, which easily leads to stress concentration. The annular power generation unit 114 can better adapt to this complex stress environment. It can be arranged around the anchor bolt 111 in the anchor hole to capture the mechanical energy generated by the deformation of the roof from multiple directions, thereby improving the efficiency of energy harvesting.

[0057] In some embodiments, in step S3, the maximum power generation of the power generation unit is determined based on the impact occurring in the tunnel. , It serves as the critical value for determining the power generation manifestation of roadway shock, and monitors the power generation in different areas of the roadway in real time. ,when If this is the case, the roadway is determined to be in a dangerous state, and measures to strengthen roadway support and relieve pressure are taken for the dangerous area.

[0058] Understandably, the maximum power generation capacity of the power generation unit is determined comprehensively based on factors such as historical data on tunnel impacts, current geological conditions, and mining status. Of course, different tunnels differ in their geological structure, mining depth, and mining methods, and therefore may experience varying impact intensities and energy release. The determination of the value needs to be based on the actual conditions of the specific tunnel, and precise analysis and calculation are required to ensure that it can accurately reflect the critical power generation state of the tunnel when the impact occurs.

[0059] In actual production process, when When this occurs, it indicates that the power generation in the area has approached or reached the critical value, meaning that the coal and rock mass in the area has been subjected to significant impact, and the roadway may be in a dangerous state. Once the roadway is determined to be in a dangerous state, measures such as strengthening roadway support and decompression are taken for the dangerous area. Strengthening roadway support can improve the roadway's load-bearing capacity and resist the damage of rockburst; decompression measures can release the stress in the coal and rock mass and reduce the intensity of rockburst. Through the implementation of these measures, the risk of roadway damage and accidents can be effectively reduced, ensuring the safety and stability of the roadway.

[0060] Therefore, this invention, based on a hazardous condition assessment and response mechanism using power generation monitoring, enables real-time early warning and timely handling of rockbursts in mine roadways. It allows for rapid response when dangerous signs appear in the roadways, taking effective measures to prevent accidents and improving the safety and reliability of coal mine production. Simultaneously, this method provides a scientific and effective means for coal mine safety management, contributing to the sustainable development of coal mines.

[0061] In some embodiments, in step S4, the warning device is connected to the power generation unit 114 and a preset power generation amount is set. When the power generation amount of the power generation unit 114 exceeds the preset power generation amount, the warning device issues a warning signal.

[0062] Understandably, setting the preset power generation capacity requires comprehensive consideration of various factors, including the geological conditions of the tunnel, mining operations, and support design. Different tunnels will have varying power generation capacities during normal operation and under impact due to differences in their geological environment, the ground stress they bear, and their support structures. Therefore, the preset power generation capacity must be scientifically and rationally set based on the specific conditions of the tunnel to accurately reflect the boundary between normal and abnormal support states.

[0063] In other words, the preset power generation provides a clear judgment standard for the warning device, enabling it to accurately determine whether there is an abnormality in the roadway based on this standard, thus improving the accuracy and reliability of the early warning.

[0064] In some embodiments, the coal mine rockburst roadway energy storage support and anti-rockburst method of the present invention further includes the following steps: S5, storing the electrical energy converted by the power generation unit 114 to supply power to the underground lighting and monitoring system.

[0065] Understandably, electrical energy is stored through an energy storage component connected to the power generation unit 114. The energy storage component needs to have a certain capacity and stable performance to promptly store the electrical energy instantaneously generated by the power generation unit 114 during a rock burst, thereby preventing energy waste. Optionally, the energy storage component can take various forms such as battery packs or supercapacitors, selected and configured according to actual needs and the specific conditions of the tunnel.

[0066] Therefore, energy storage components resolve the contradiction between the instantaneity of power generation and the continuity of power use. The energy release from rock bursts is instantaneous, while downhole lighting and monitoring systems require a continuous and stable power supply. Energy storage components can store the instantaneously generated electrical energy and provide a stable power output when needed, ensuring the normal operation of the system.
