Description

Technical Field

[0001] The invention relates to the technical field of coal mining equipment, in particular to an anti-outburst tunneling machine with a real-time early warning function for coal and gas outburst dangers. Background Art

[0002] Coal and gas outbursts are the main reasons that affect mine production safety. According to statistics, in the past three years, more than 70% of coal and gas outburst accidents in China were caused by the use of roadheaders for excavation. How to prevent the danger of coal and gas outbursts caused by roadheaders for excavation has become a difficult problem that needs to be urgently solved in today's mining industry.

[0003] In the mine work, the fast excavation speed of the roadheader aggravates the stress tension of the working face; the faster the excavation speed of the tunnel, the greater the stress tension; if this increased mining stress is superimposed with the residual structural stress of the geological structural belt (faults, folds, changes in coal seam thickness, etc.) encountered during the tunneling, the risk of ground stress induced outburst will be greatly increased. When using a roadheader to excavate the tunnel, the roadheader will cause damage to the working face and the surrounding rock of the tunnel, and the impact force is small, and the stress concentration point in front of the working face is closer to the front of the working face, which weakens the protection of the safety coal pillar and makes it easier for ground stress to induce outburst; and during the excavation of the roadheader, the operators work near the front, and if an outburst occurs, it often affects their safety.

[0004] A Chinese patent with publication number CN115199215A discloses an anchor support device and a tunnel boring machine equipped with the device. The multi-directional swing arm mechanism can realize the rotation of the drilling rig in multiple planes, thereby adjusting the angle of the drilling point supported by the drilling rig, realizing timely adjustment in the case of roof collapse, maximizing the radial anchoring force, and increasing the stability of the surrounding rock.

[0005] However, this solution has some defects. Although the multi-directional swing arm mechanism provides convenience for transportation and operation, the direct protection measures for the operators are still insufficient. In addition, the most important thing to prevent during the tunneling operation of the tunnel boring machine is coal and gas outbursts. However, this solution does not have the function of early warning of coal and gas outbursts, and cannot track and warn of the danger of outbursts in real time. The sensors directly installed on the tunnel boring machine will cause problems in fixing the sensors due to the long-term vibration of the tunnel boring machine during operation, resulting in inaccurate monitoring data and a lack of early warning and protection of the danger of outbursts for the construction personnel on the entire working face. Summary of the invention

[0006] In view of the above problems in the prior art, the present invention is proposed.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an anti-outburst tunneling machine with a real-time early warning function of coal and gas outburst danger, comprising: a tunneling machine assembly, including a tunneling machine body;

[0008] An early warning component arranged on the end face of the tunnel boring machine body comprises a mounting shell, a mounting plate arranged on the inner wall of the mounting shell, and a sensor component arranged on the end face of the mounting plate;

[0009] The protection component arranged on the inner wall of the installation shell includes a bottom column, a limiting shell sleeved on the outer wall of the bottom column, a movable sleeve movably arranged on the inner wall of the limiting shell, and a fixed sleeve;

[0010] An electric control early warning platform is provided at the end of the tunnel boring machine body, and the electric control early warning platform includes a main circuit board assembly, which is composed of seven single-chip microcomputers and is used for real-time analysis and early warning of the danger of coal and gas outburst;

[0011] The electronic control early warning platform also includes:

[0012] The real-time data collection component collects ground stress, gas concentration, wind speed, tunnel boring machine operation status and smoke data through wireless communication to provide data support for coal and gas outburst warning. It also includes a front camera component and a rear camera component. The front camera component obtains the coal seam occurrence and rock stratum geological structure data of the tunneling working face, and the rear camera component obtains the construction status of personnel;

[0013] Wireless data sending and receiving components, used to upload the working status and analysis results of the anti-breakout tunneling machine and receive instructions and prompt information from the ground central station;

[0014] The power-off control component cuts off or restores the power supply equipment at the tunneling face according to the analysis results of the anti-outburst electric control early warning platform.

[0015] As a preferred solution of the anti-outburst tunneling machine with real-time warning function of coal and gas outburst danger described in the present invention, the electric control warning platform is also provided with a construction personnel positioning component, an audible and visual alarm and a voice alarm; the main circuit board component is provided with a core control processor for installing the tunneling machine coal and gas outburst real-time analysis, warning and control software, for analyzing and processing the data transmitted by the front camera component, the rear camera component, the real-time data acquisition component and the construction personnel positioning component, and controlling the audible and visual alarm, the voice alarm and the power-off control component.

When the sound and light alarm is green, it means that there is no outburst danger and the working face is under normal construction. When the sound and light alarm is blue, it means that the outburst danger has reached the threat value. At this time, it is necessary to slow down the cutting section speed and adopt intermittent Operation mode, reduce the concentration of concentrated stress and weaken the risk of outburst; when the sound and light alarm is orange, it means that the risk of outburst has reached a dangerous value. At this time, it is necessary to stop the cutting section operation and cut off the power supply of the cutting head motor of the anti-outburst tunneling machine. By stopping the excavation, the already very tense concentrated stress is transferred to the deep part of the working face. At this time, it is strictly forbidden for personnel to work within 20m in front of the anti-outburst tunneling machine; when the sound and light alarm is red, it means that the risk of outburst has reached an emergency value. At this time, it is necessary to turn on the sound and light voice prompt, issue a stop operation and evacuation order to each operator on the working face, and cut off the power supply of all equipment on the working face except the electric control early warning platform.

[0046] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0047] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0048] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0049] Example 1

[0050] For the first embodiment of the present invention, see Figure 1-Figure 10 This embodiment provides an anti-outburst tunneling machine with real-time early warning function of coal and gas outburst danger.

[0051] Specifically, refer to Figure 1~Figure 5 , including a tunnel boring machine assembly 100, which includes a tunnel boring machine body 101;

[0052] The early warning assembly 200 disposed on the end surface of the tunnel boring machine body 101 includes a mounting shell 201, a mounting plate 202 disposed on the inner wall of the mounting shell 201, and a sensor component 203 disposed on the end surface of the mounting plate 202;

[0053] The protection assembly 300 disposed on the inner wall of the installation shell 201 includes a base column 301 , a limiting shell 302 sleeved on the outer wall of the base column 301 , a movable sleeve 303 movably disposed on the inner wall of the limiting shell 302 , and a fixed sleeve 304 .

[0054] Among them, the early warning component 200 is installed on the rear side of the tunnel boring machine body 101 to reduce the vibration impact of the front drill bit during cutting and tunneling operations of the tunnel boring machine, and at the same time reduce the risk of being hit by gravel generated by the front drill bit during tunneling. The mounting plate 202 is installed inside the mounting shell 201. The sensor component 203 on the upper surface of the mounting plate 202 includes a methane sensor and a wind speed sensor, etc., which are used to monitor the real-time gas concentration and wind speed inside the mine tunnel when the tunnel boring machine body 101 is tunneling, so as to evaluate the risk of gas outburst.

[0055] The protection component 300 is fixed inside the mounting shell 201 and symmetrically distributed around the mounting plate 202 for protecting the mounting plate 202. It is fixed to the inner surface of the mounting shell 201 through the bottom column 301, and the movable sleeve 303 and the fixed sleeve 304 are fixed above the bottom column 301 through the limiting shell 302 outside the bottom column 301. The mounting shell 201 is provided with a vibration-damping component to dampen the mounting plate 202, reduce the vibration generated during the operation of the tunnel boring machine body 101, and avoid long-term and large-scale vibrations that may cause accidents to the sensor component 203 inside the mounting shell 201, such as loose installation parts causing position displacement, etc., to avoid the inability to accurately measure or monitor the target parameters due to the position displacement of the sensor component 203, thereby introducing measurement errors, causing signal distortion or failure to correctly reflect the actual situation.

[0056] When an accident occurs to the original vibration-damping component of the mounting shell 201, the movable sleeve 303 will be triggered to move. The movable sleeve 303 will operate inside the limiting shell 302 and move upward, and together with the fixed sleeve 304, it will limit the vibration-damping range of the mounting plate 202 to prevent the failure of the vibration-damping component in one corner from affecting the remaining vibration-damping components, thereby causing the position of the sensor component 203 on the surface of the mounting plate 202 to shift or the entire mounting plate 202 to detach.

[0057] In summary, when in use, the early warning component 200 is installed at a rear position on the upper surface of the tunnel boring machine body 101 to reduce the vibration generated during the tunneling operation and the risk of falling debris from above. A vibration-damping component is installed inside the mounting shell 201 to dampen the mounting plate 202, thereby reducing the vibration generated during the tunneling operation of the tunnel boring machine body 101 and affecting the sensor component 203 on the surface of the mounting plate 202. At the same time, a protective component 300 is also arranged around the mounting plate 202. When an accident occurs to the original vibration-damping component inside the mounting shell 201, the protective component 300 at the corresponding position will automatically operate, and the internal movable sleeve 303 will rotate and rise, cooperating with the fixed sleeve 304 to limit the vibration range of the mounting plate 202, so as to avoid excessive up and down movement that affects the vibration-damping components at other positions, and ultimately cause the overall detachment of the mounting plate 202, resulting in damage or displacement of the sensor component 203, resulting in parameter detection errors, and failure to correctly reflect the actual situation.

[0058] Example 2

[0059] This is the second embodiment of the present invention, which is implemented based on the previous embodiment.

[0060] Specifically, refer to Figure 3 and Figure 4A pillar 2011 is fixed to the inner wall of the mounting shell 201 and a limiting ring 2012 is fixed to the outer wall of the pillar 2011. A first elastic member 2013 is provided on the end face of the limiting ring 2012 and the first elastic member 2013 is sleeved on the outer wall of the pillar 2011. A fixing nut 2014 is provided at the end of the first elastic member 2013 and the fixing nut 2014 is screwed to the end of the pillar 2011.

[0061] Among them, a pillar 2011 is fixed at each of the four corners of the upper surface of the inner wall of the mounting shell 201, and a limiting ring 2012 is fixed on the surface of the pillar 2011. The first elastic member 2013 is a shock-absorbing spring, which is sleeved on the outside of the pillar 2011 and placed on the upper surface of the limiting ring 2012. At the same time, a fixing nut 2014 is screwed at the top position of the pillar 2011, and there is a shock-absorbing pad under the fixing nut 2014. The shock-absorbing pad and the fixing nut 2014 are both above the first elastic member 2013.

[0062] Better, refer to Figure 4 A connecting plate 2021 is fixed to the end surface of the mounting plate 202 , a connecting ring 2022 is provided on the end surface of the connecting plate 2021 , and the connecting ring 2022 is sleeved on the outer wall of the first elastic member 2013 .

[0063] Among them, connecting plates 2021 are fixed to the lower surface of the four corners of the mounting plate 202, and the position of the connecting plate 2021 is opposite to that of the pillar 2011. A connecting ring 2022 is arranged on the lower surface of the connecting plate 2021. The connecting ring 2022 is hollow and is integrally sleeved on the outside of the first elastic member 2013. The top end of the connecting ring 2022 is gathered inward to form a ring sleeve on the top end of the first elastic member 2013, and is located below the shock-absorbing pad and the fixing nut 2014. The nut 2014 is fixed by turning the knob to adjust the height of the fixing nut 2014 above the pillar 2011 and adjust the amplitude of the shaking of the mounting plate 202 during vibration.

[0064] In summary, when in use, the pillar 2011 is fixed on the inner wall of the mounting shell 201 as the main structure for support and shock absorption. The external limit ring 2012 is used to support the first elastic member 2013 to limit the position of the first elastic member 2013 when the first elastic member 2013 is performing shock absorption. The connecting plate 2021 on the lower surface of the mounting plate 202 passes through the pillar 2011. The connecting ring 2022 on the surface of the connecting plate 2021 is sleeved on the outside of the first elastic member 2013 and below the fixing nut 2014. By adjusting the height of the fixing nut 2014 at the top of the pillar 2011, the preload force and working range of the first elastic member 2013 can be changed to control the shock absorption effect.

[0065] When the tunnel boring machine body 101 is performing tunneling operations, the vibration generated by the drill bit at the front end is transmitted to the vehicle body at the rear end, driving the tunnel boring machine body 101 to vibrate as a whole. At this time, the external vibration is transmitted to the mounting shell 201 above the vehicle body, and then to the internal mounting plate 202. At this time, the mounting plate 202 will drive the connecting plate 2021 and the connecting ring 2022 to vibrate together on the outside of the pillar 2011. The connecting ring 2022 is sleeved on the outside of the first elastic member 2013, so the vibration will be further transmitted to the first elastic member 2013. The first elastic member 2013 absorbs and disperses the vibration energy through its elastic deformation, thereby reducing the vibration amplitude transmitted to the mounting plate 202, so that the sensor component 203 on the upper surface of the mounting plate 202 reduces the impact of the vibration.

[0078] Among them, the outer wall of the fixed sleeve 304 is symmetrically provided with a rising groove 3043 and the top position of the rising groove 3043 is also connected to a stop groove 3044, and the front end of the fixing pin 3036 extends to the inside of the stop groove 3044. When the movable sleeve 303 moves upward, it is affected by the stop groove 3044 and rotates ninety degrees outside the fixed sleeve 304. At this time, the fixing pin 3036 slides from the rising groove 3043 into the inside of the stop groove 3044. At this time, the connecting head 3031 at the top of the movable sleeve 303 corresponds to the position of the fixed head 3045 at the top of the fixed sleeve 304. At this time, the fixed head 3045 is located above the connecting plate 2021, and the connecting head 3031 reaches the bottom of the connecting plate 2021 after rotating ninety degrees, clamping the connecting plate 2021 between the fixing head 3045 and the connecting head 3031, and they are temporarily not in contact with each other.

[0079] A motion groove 401 is formed through the end face of the push rod 400, the push rod 400 is hinged to the inner wall of the cavity 3047 and the hinge rod is arranged on the inner wall of the motion groove 401, a hinge head 402 is arranged at one end of the push rod 400 and an angle block 403 is hinged to the inner wall of the hinge head 402, a push block 404 is arranged at one end of the angle block 403 and the end of the push block 404 extends to the outer wall of the cavity 3047.

[0080] Among them, the push rod 400 moves inside the cavity 3047 inside the fixed head 3045 and is hinged inside the fixed head 3045. The hinged rod is in the motion groove 401 on the surface of the push rod 400. The hinged head 402 hinged at the end of the push rod 400 is located in the fixed block 3046. The hinged head 402 is hinged with an angle block 403 inside, and the hinge hole of the angle block 403 is a vertical groove. The push block 404 and the angle block 403 are a whole. The push block 404 is located below the angle block 403, and the bottom end of the push block 404 extends out from the lower surface of the fixed block 3046.

[0081] Preferably, a rack 405 is provided at the other end of the push rod 400, a limiting column 406 is provided in the cavity 3047, a gear 407 is sleeved on the end of the limiting column 406 and the gear 407 is meshed with the rack 405, and an arc opening 408 is opened at the other end of the limiting column 406 and the arc opening 408 is in contact with the limiting block 3034.

[0082] Among them, the rack 405 at the other end of the push rod 400 is meshed with the gear 407 inside the cavity 3047 above the limit column 406. When the push rod 400 moves, the rack 405 drives the gear 407 to rotate, thereby causing the limit column 406 below to rotate, and the bottom of the limit column 406 extends into the inside of the inclined groove 3033 on the surface of the movable sleeve 303. The arc 408 at the bottom of the limit column 406 is initially in contact with the limit block 3034 on the surface of the inclined groove 3033. When the limit column 406 rotates, the arc 408 rotates along the outer wall of the limit block 3034, and the bottom end of the limit column 406 enters the inside of the inclined groove 3033 from the inner side of the limit block 3034 and slides downward, finally entering the bottom of the inclined groove 3033 and sliding into the fixed groove 3035.

[0083] In summary, during use, when the tunnel boring machine body 101 is performing tunneling work, the vibration is transmitted to the mounting shell 201 on the vehicle body, and the mounting plate 202 vibrates inside the mounting shell 201, and the vibration is transmitted to the first elastic member 2013 through the connecting plate 2021 and the connecting ring 2022 below for shock absorption. Since the connecting ring 2022 will continuously impact the shock absorbing pad and the fixing nut 2014 above when moving up and down, the fixing nut 2014 may be loosened. When the fixing nut 2014 on one side is loosened, the amplitude of the up and down movement of the connecting plate 2021 on this side will change, which may cause the fixing nuts 2014 around to loosen or fall off, and eventually cause the mounting plate 202 to be unfixed, causing the sensor component 203 above to be affected, and accurate data cannot be measured in time.

[0084] When the fixing nut 2014 on one side is loosened, the corresponding connecting plate 2021 will move more widely. The height of the fixing block 3046 at the top of the fixing sleeve 304 is slightly higher than the initial fixing height of the fixing nut 2014. When the fixing nut 2014 is loosened and moves upward, it gradually becomes level with the height of the fixing block 3046. At this time, the lower connecting plate 2021 will vibrate again and contact the bottom of the fixing block 3046, and contact the push block 404 under the angle block 403, pushing the push block 404 upward, and the hinge column above the angle block 403 slides from top to bottom in the vertical groove opened in the outer wall of the hinge head 402 at the top of the push rod 400, and pushes the push rod 400 to move backward. During movement, the rack 405 at the tail drives the gear 407 to rotate, at which time the limit column 406 rotates, the limit column 406 rotates ninety degrees, and the arc 408 rotates to the inside of the inclined groove 3033 along the limit block 3034. At this time, the movable sleeve 303 below loses the resistance of the limit column 406 and moves upward under the push of the second elastic member 3014 below. The fixing pin 3036 outside the movable sleeve 303 slides upward from the bottom in the rising groove 3043 on the outer wall of the fixed sleeve 304. At this time, the movable sleeve 303 rotates and moves upward, and the fixing pin 3036 finally slides into the inside of the stop groove 3044, and the limit column 406 also slides along the inclined groove 3033 into the inside of the fixed groove 3035.

[0085] At this time, after the movable sleeve 303 rotates ninety degrees, the upper abutment block 3032 and the fixed block 3046 on the top of the fixed sleeve 304 correspond to each other and are located below the connecting plate 2021, and the outer side position of the fixing pin 3036 is inside the groove 3022 of the inner circle of the limiting shell 302. When the movable sleeve 303 rotates and rises, the fixing pin 3036 is located below the convex ring 3023 at the top of the limiting shell 302, limiting the movable sleeve 303 so that the movable sleeve 303 cannot continue to move upward. At the same time, since the other end of the fixing pin 3036 is in the stop groove 3044, a relative distance is maintained between the fixed sleeve 304 and the movable sleeve 303, and the highest position of the upward movement of the fixed sleeve 304 and the movable sleeve 303 is limited by the fixing pin 3036.

[0086] When the connecting plate 2021 moves upward by vibration, it abuts against the fixed block 3046 at the top of the fixed sleeve 304 and cannot move upward any further. When the connecting plate 2021 moves downward by vibration, it abuts against the abutment block 3032 on the outer surface of the movable sleeve 303 below, and drives the abutment block 3032 to move downward. The movable sleeve 303 and the fixed sleeve 304 are driven downward by the abutment block 3032, and the second elastic member 3014 and the third elastic member 3015 inside are squeezed to perform shock absorption. Through the cooperation of the movable sleeve 303 and the fixed sleeve 304, the loosened fixing nut 2014 is replaced to limit the vibration amplitude of the connecting plate 2021, so as to avoid the vibration amplitude of the connecting plate 2021 on one side being too large, which will cause the other fixing nut 2014 to loosen together, and finally cause unstable fixation and error in the detection data of the sensor component 203.

[0087] Example 4

[0088] For the fourth embodiment of the present invention, see Figure 11-Figure 14 , this embodiment provides an electric control early warning platform.

[0089] An electric control early warning platform is provided at the end of the tunnel boring machine body 101. The electric control early warning platform includes a main circuit board assembly, which is composed of seven single-chip microcomputers and is used for real-time analysis and early warning of the danger of coal and gas outbursts;

[0090] The electronic control early warning platform also includes:

[0091] The real-time data collection component collects ground stress, gas concentration, wind speed, tunnel boring machine start and stop status, and smoke data through wireless communication to provide data support for coal and gas outburst warning. It also includes a front camera component and a rear camera component. The front camera component obtains the coal seam occurrence and rock stratum geological structure data of the tunneling working face, and the rear camera component obtains the construction conditions of personnel;

[0092] Outburst is closely related to the occurrence conditions and geological structure of coal seams. Faults, bends, thickening and thinning of coal seams, and changes in the rock structure of the top and bottom plates of coal seams are important factors affecting the danger of coal and gas outburst. In addition, the danger of outburst is also closely related to the tunneling technology and tunneling speed of the tunnel boring machine. The design of the front camera component of the anti-outburst tunnel boring machine is to collect this information, and the combined analysis with ground stress and gas outburst volume can greatly improve the accuracy of outburst warning.

[0093] In addition to taking pictures, the front camera assembly can also compress the captured image data to reduce the amount of data communication, and decompress and restore it in the main circuit board assembly or the ground center station.

[0094] The rear camera assembly can visualize the underground excavation construction, understand the working status of the personnel on the working face at any time, and conveniently organize the orderly retreat of personnel when encountering danger.

[0095] The anti-outburst tunneling machine combines the coal seam occurrence of the working face obtained by the front camera component, and analyzes the changing trends of ground stress, gas concentration, and gas outburst volume in the same space to warn of the danger of outbursts.

[0096] Wireless data sending and receiving components, used to upload the working status and analysis results of the anti-breakout tunneling machine and receive instructions and prompt information from the ground central station;

[0097] The power-off control component cuts off or restores the power supply equipment at the tunneling face according to the analysis results of the electronic control and early warning platform of the anti-outburst tunneling machine.

[0098] All external data communication of the electric control early warning platform is completed by wireless transmission, which will not add any cables or construction constraints to the anti-burst tunnel boring machine.

[0099] The electronically controlled early warning platform is also provided with a construction personnel positioning component, an audible and visual alarm, and a voice alarm; a core control processor is provided in the main circuit board component for installing the tunnel boring machine coal and gas outburst real-time analysis, early warning and control software, for analyzing and processing the data transmitted by the front camera component, the rear camera component, the real-time data acquisition component, and the construction personnel positioning component, and for controlling the audible and visual alarm, the voice alarm, and the power-off control component.

[0100] The core control processor obtains or updates the working face outburst hazard judgment criteria from the KJ918 mining coal and gas outburst prediction parameter monitoring system through wireless networking, and combines the collected original data for real-time analysis to determine the current outburst hazard level and give corresponding construction operation process prompts.

[0101] The construction personnel positioning component includes a precise positioning base station installed on the tunnel wall of the tunneling construction area of ​​the tunnel boring machine, and a precise locator carried by the underground workers, which realizes the real-time transmission of personnel location information by wireless means. The precise positioning base station is installed on the tunnel wall of the tunneling construction area of ​​the tunnel boring machine; the precise locator can capture the working position of the underground workers in real time through the positioning base station, and transmit the personnel location information to the electric control early warning platform by wireless means, providing real-time data for mine production or management personnel, and providing a basis for commanding and supervising the work of underground personnel under normal circumstances; it can provide a basis for rapid rescue after an accident occurs.

[0102] The sound and light alarm includes four colors of light: green, blue, orange and red, which correspond to different warning states respectively. The core control processor analyzes the collected raw data in real time to determine the current degree of danger of outbursts. Combined with the mining operation procedures of the working face, it gives the current construction process prompts. When the sound and light alarm is green, it means there is no danger of outbursts and the working face is under normal construction. When the sound and light alarm is blue, it means that the danger of outbursts has reached the threat value. At this time, it is necessary to slow down the cutting speed and adopt intermittent operation mode to reduce the concentration of concentrated stress and weaken the occurrence of outbursts. When the sound and light alarm is orange, it means that the danger of outburst has reached the dangerous value. At this time, it is necessary to stop the cutting section operation and cut off the power supply of the cutting head motor of the anti-outburst tunnel boring machine. By stopping the excavation, the already very tense concentrated stress is transferred to the deep part of the working face. At this time, it is strictly forbidden to operate within 20m in front of the anti-outburst tunnel boring machine; when the sound and light alarm is red, it means that the danger of outburst has reached the critical value. At this time, it is necessary to turn on the sound and light voice prompt, issue a stop operation and evacuation order to each operator on the working face, and cut off the power supply of all equipment on the working face except the electric control early warning platform. The threat value, danger value, and critical value are all set by technical personnel in this field according to the on-site construction conditions.

[0103] According to the four states of coal and gas outburst hazard warning on the electric control early warning platform, construction workers can arrange their work according to the color of the light emitted by the sound and light alarm.

[0104] The voice alarm cooperates with the sound and light alarm to play the prompt information of the ground central station or the electronic control early warning platform of the anti-outburst tunnel boring machine in the form of voice broadcast, upload the working status and analysis results of the anti-outburst tunnel boring machine in the form of wireless communication, and receive the instructions and prompt information issued by the ground central station, transmit the instructions of the ground central station to the core control processor of the electronic control early warning platform, and transmit the voice prompt information issued by the ground central station to the voice alarm through the core control processor of the electronic control early warning platform.

[0105] The platform display of the cab of the anti-burst tunnel boring machine is the center of the electronic control early warning platform. It displays all the original data and the analysis results of the sudden warning. The prompt information sent by the ground central station and the prompt information of the electronic control early warning analysis software are displayed on the display screen in a scrolling manner. The power supply and power failure status of the auxiliary equipment of the tunnel boring machine system are displayed. The tunnel boring machine driver directs the personnel in the construction area to work safely through the information provided by the display.

[0106] The power-off control component includes eight control loops, which receive instructions from the analysis software of the anti-burst tunneling machine electronic control early warning platform, and control the power-off or power-on of the eight power supply devices on the tunneling working face. It is used to remotely control the power-off or power-on of key power supply equipment on the tunneling working face, such as special motors and transformers, to improve emergency response capabilities.
