Description

Technical Field

[0001] The invention belongs to the technical field of underground coal mine safety monitoring, and relates to a coal mine shaft safety monitoring device and a monitoring method thereof. Background Art

[0002] Coal mining is an underground operation. Compared with open-pit mining, underground mining conditions are more complex and more difficult. During underground mining, the presence of harmful gases such as methane, ethane, ethylene, acetylene, CO, CO2, and harmful particulate matter such as dust and dirt in the environment seriously threatens the life safety of workers.

[0003] The prior art solution discloses a coal mine safety monitoring and early warning device and method, which compares the average gas flow rate with a preset flow rate value. When the average gas flow rate is less than the preset flow rate value, it is generated and sent to a cleaning mechanism so that the cleaning mechanism cleans dust from the gas filtering mechanism; when the average gas flow rate is greater than or equal to the preset flow rate value, a detection instruction is generated and sent to a gas composition detector so that the gas composition detector detects the gas composition and content; then, the corresponding alarm threshold is queried according to the gas composition detected, and the content of each gas component is judged according to each alarm threshold. When the content of the gas component is greater than the corresponding alarm threshold, the alarm unit is activated to alarm.

[0004] The existing technical solution also discloses a coal mine safety intelligent broadcast warning system, which specifically includes a mine business system information collection unit connected to a warning server, the warning server is connected to the input end of a voice conversion unit through a network module, the output end of the voice conversion unit is connected to the signal input end of a power amplifier, the signal output end of the power amplifier is connected to the signal input end of a warning control host, and the output end of the warning control host is connected to a network audio alarm through a network module.

[0005] However, the existing technical solutions are still unable to achieve maximum protection for coal mine equipment and workers, and are unable to monitor the status of underground gas in real time, and the safety hazards are still high. Therefore, it is urgent to design and develop a coal mine shaft safety monitoring device and a monitoring method to overcome the defects of the existing technology and meet the actual application needs. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a coal mine shaft safety monitoring device and a monitoring method thereof. In the present invention, through the coordinated setting of a control unit, an analysis unit and an alarm unit, real-time monitoring of the gas components and concentrations existing in underground coal mines can be achieved, and the level of safety hazards can be classified according to the monitoring results, thereby facilitating timely corresponding alarm operations, greatly reducing the risks of underground operations, and ensuring the safety of coal mine workers and coal mine equipment.

[0007] To achieve this object, the present invention adopts the following technical solutions:

[0009] The analysis unit includes a gas online detector, a camera device and a coordinate module. The gas online detector is used to detect the gas composition and concentration in the coal mine shaft and feed back to the control unit. The coordinate unit is set on the camera device. The coordinate module is used to control the corresponding camera device to monitor the received coordinates, obtain the corresponding monitoring channel link, and send the obtained monitoring channel link and parameters to the control unit.

[0010] The alarm unit is used to issue an alarm instruction and feed back to the control unit when the gas operation data analyzed by the analysis unit exceeds a set threshold.

[0011] In the present invention, through the coordinated setting of the control unit, the analysis unit and the alarm unit, the gas composition and concentration existing in the underground coal mine can be monitored in real time, and the level of safety hazards can be divided according to the monitoring results, so as to facilitate timely corresponding alarm operations, greatly reduce the risks of underground operations, and ensure the safety of coal mine workers and coal mine equipment.

[0012] It should be noted that the specific existence forms of the control unit, analysis unit and alarm unit are not particularly limited in the present invention, as long as each unit can achieve its own purpose, and the control unit can be in the form of a computer terminal.

[0013] It should be noted that the analysis units in the present invention can be set to 1, 2, 3, 4, 5, or 6, and the list is not exhaustive here. The specific number can be evenly set according to the height of the well, and the gas state of each position in the well can be collected in real time.

[0014] It should be noted that the alarm signal emitted by the alarm unit in the present invention may be in a single form or a combination of sound, light or text, and those skilled in the art may make adaptive adjustments according to actual conditions.

[0015] As a preferred technical solution of the present invention, the monitoring device further includes a display unit, and the display unit is electrically connected to the control unit and is used to display data of the control unit.

[0016] It should be noted that the specific form of the display unit is not particularly limited in the present invention, and those skilled in the art may make adaptive adjustments according to actual conditions, wherein the display unit may be a display screen.

[0017] As a preferred technical solution of the present invention, the analysis unit also includes a gas filtering structure, which is used to collect the gas in the underground coal mine to be tested in real time, filter out particulate matter in the gas, and transmit the filtered gas to the gas online detector.

[0018] It should be noted that the present invention does not impose any special limitation on the specific existence form of the gas filtering structure and the gas online detector, and each part only needs to be able to achieve its respective purpose.

[0019] As a preferred technical solution of the present invention, the gas filtering structure includes a hollow shell and at least one layer of filter mesh arranged in the hollow shell, for example, it can be 1 layer, 2 layers, 3 layers, 4 layers, 5 layers, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0020] Preferably, one end of the hollow shell is arranged at the gas outlet of a main pipeline laid in an underground coal mine, and the other end is detachably connected to the gas online detector.

[0021] It should be noted that the filter in the present invention can filter out particulate matter in the gas, thereby ensuring the accuracy of gas analysis to the greatest extent.

[0022] It should be noted that the present invention does not specifically limit the specific material, shape, size, etc. of the hollow shell, and those skilled in the art can make adaptive adjustments according to actual conditions.

[0023] As a preferred technical solution of the present invention, the mesh diameter of the filter is 6 to 8 μm, for example, it can be 6 μm, 6.2 μm, 6.4 μm, 6.6 μm, 6.8 μm, 7 μm, 7.2 μm, 7.4 μm, 7.6 μm, 7.8 μm, 8 μm, etc., but is not limited to the listed values, and other unlisted values ​​within the numerical range are also applicable.

[0024] The mesh diameter of the filter screen is limited to 6 to 8 μm in the present invention because the gas can be filtered to the greatest extent within this range, making the gas components easier to detect without damaging the gas online detector. If it is not within this limited range, it will lead to incomplete filtration of particulate matter in the gas, damaging the gas online detector, which is not conducive to the safe detection of underground gas.

[0028] It should be noted that the specific size and material of the gas collection structure are not particularly limited in the present invention, and those skilled in the art can make adaptive adjustments according to actual conditions. Among them, the gas collection structure in the present invention does not need to adopt a vacuum pump or other structures, and only needs to maintain the original flow rate of the gas to enable the gas online detector to maintain good operation.

[0031] It should be noted that when the difference between the stroke alarm instruction and the control instruction of the present invention is greater than 1, the risk level is level 1. This conclusion is based on the difference adjustment after processing the gas data measured in actual conditions. Within this difference, there will be no safety hazard to the underground environment. If it exceeds this difference, it will easily cause discomfort to the operator, and more seriously affect the safety of the operating environment and there will be a risk of explosion.

[0033] The monitoring area of ​​the camera device is obtained, the monitoring area is converted into a coordinate area, and the coordinate area is marked at a corresponding position in the coal mine shaft model. When the coordinate module receives the input coordinates, the camera device is controlled to align with the corresponding coordinates for monitoring according to the received coordinates.

[0034] It should be noted that the present invention can monitor the target object faster and more accurately by designing a coordinate module, so that when it exceeds a threshold, an alarm and emergency processing can be issued in the first time.

[0035] In a second aspect, the present invention provides a monitoring method of the monitoring device for coal mine shaft safety according to the first aspect, the monitoring method comprising:

[0036] Obtain the gas components and concentration values ​​detected by the gas online detector in real time;

[0037] Compare the gas composition and concentration value with the preset value, and when the gas composition and concentration value are greater than the preset value, the alarm unit generates an alarm instruction and sends it to the control unit and the emergency processing unit respectively;

[0038] The emergency processing unit takes corresponding emergency measures for fault targets with a risk level of 1 by comparing the difference between the alarm command and the control command.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] In the present invention, through the coordinated setting of the control unit, the analysis unit, the alarm unit and the emergency processing unit, real-time monitoring of the gas existing in the underground coal mine can be achieved, and the hazard level of the safety hazard can be accurately judged based on the monitoring results, so as to facilitate timely corresponding alarms and emergency operations, greatly reduce the risks of underground operations, and ensure the safety of coal mine workers and coal mine equipment.
