[0023] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0024] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0025] As introduced in the background technology, the conventional monitoring method used in the related technology can only monitor certain points when monitoring high-temperature blastholes, and it is difficult to fully monitor the temperature changes inside the blastholes, resulting in low monitoring accuracy, which is likely to pose a serious threat to the safety of the mining area. In view of the above defects, a full-hole depth monitoring system, full-hole depth monitoring method and device for high-temperature blastholes are provided in the embodiments of the present invention.

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0027] According to one aspect of an embodiment of the present invention, a full-hole depth monitoring system for a high-temperature blasthole is provided. Figure 1 Schematic diagram of a full-hole depth monitoring system for a high-temperature blasthole according to an embodiment of the present invention. Figure 1 As shown, the full-hole depth monitoring system of the high-temperature blasthole includes: a data acquisition module, a transmission module, a control module and an instant cooling device. The full-hole depth monitoring system of the high-temperature blasthole is described in detail below.

[0028] Data acquisition module, the data acquisition module is used to collect temperature data of the full hole depth in the high-temperature blasthole. The high-temperature blasthole refers to the blasthole whose temperature is higher than the temperature threshold during open-pit coal mining. The blasthole is the hole used to load the materials required for blasting in the blasting operation. The full hole depth refers to the entire depth range from the hole mouth to the bottom of the high-temperature blasthole. The data acquisition module is connected in communication with the transmission module.

[0029] In this embodiment, the data acquisition module (i.e. Figure 1 The data acquisition system shown in the figure collects temperature data of the entire hole depth in the high-temperature blasthole to monitor the temperature in the high-temperature blasthole in real time.

[0030] The "high-temperature blasthole" here specifically refers to the abnormal increase in the temperature inside the blasthole due to spontaneous combustion of the underground coal seam or other high-temperature heat sources during the open-pit coal mining process. Open-pit coal mines will leave goaf areas during the mining process. If these areas are leaking air and oxygen for a long time, the coal seams may spontaneously combust under the action of their own weight and oxygen, resulting in high-temperature fire zones. High-temperature fire zones will release heat energy, smoke and toxic and harmful gases, polluting the environment and posing a major threat to the safe production of mining areas. Before the blasting operation, it is necessary to drill blastholes in the predetermined blasting area and then load explosives into the blastholes. However, if there is a high-temperature fire zone in the area where the blasthole is located, the temperature inside the blasthole may rise abnormally, which not only affects the stability and blasting effect of the explosives, but may also cause the explosives to explode prematurely, causing serious safety accidents. For this type of blasthole, special monitoring and early warning measures need to be taken to ensure the safety of blasting operations.

[0031] The transmission module is used to transmit the temperature data received from the data acquisition module to the control module, and the transmission module is also connected to the control module for communication.

[0032] In this embodiment, the transmission module (ie Figure 1 The data transmission system shown in FIG. 1 receives the temperature data transmitted by the data acquisition module, and uses the data transmission module to transmit the temperature data to the control module (i.e. Figure 1 The control system in the control module), or it can be understood as using the data sending module to send the temperature data to the data receiving module in the control module for receiving data; the data sending module and the data receiving module here are both sub-modules in the transmission module for data transmission, and of course the data receiving module can also be used as a sub-module in the control module for receiving data; the outgoing module can transmit temperature data wirelessly (4 / 5G), and of course, other communication methods can also be used for data transmission, which is not specifically limited here.

[0033] The control module is used to parse the temperature data to generate a warning message and trigger the instant cooling device to start when the analysis result indicates that the borehole temperature is greater than a preset temperature threshold. The control module is also connected to the instant cooling device for communication.

[0034] In this embodiment, the control module can process and analyze the received temperature data. When the analysis result indicates that the borehole temperature is greater than the preset temperature threshold, that is, the borehole is at a high temperature, a corresponding warning message can be generated, and the instant cooling device can be triggered to start.

[0035] The instant cooling device is used to start the water injection program and perform the water injection operation when receiving the early warning information, so that the temperature of the blast hole is not greater than the preset temperature threshold.

[0036] In this embodiment, the instant cooling device can start the water injection program to perform water injection cooling when it receives the early warning information, that is, when the control module triggers the start of the instant cooling device, so that the temperature of the blast hole drops to a state not greater than the preset temperature threshold.

[0037] From the above, it can be seen that in the full-hole depth monitoring system of the high-temperature blasthole provided in the above embodiment of the present invention, the data acquisition module, the transmission module, the control module and the instant cooling device are communicated and connected with each other, so that the temperature of the full hole depth in the blasthole is monitored in real time through the coordinated work of several modules in the full-hole depth monitoring system, and an early warning is issued in time when the temperature of the blasthole is too high and corresponding measures are taken to cool down the temperature. The temperature within the full hole depth range of the blasthole is monitored to comprehensively monitor the instant effect of the temperature changes inside the blasthole, thereby improving the accuracy and comprehensiveness of blasthole temperature monitoring and effectively avoiding potential safety hazards.

[0038] Therefore, the technical solution provided by the above-mentioned embodiment of the present invention solves the technical problem that when using traditional monitoring methods in related technologies to monitor high-temperature blastholes, monitoring can only be performed at certain points, and it is difficult to comprehensively monitor the temperature changes inside the blasthole, resulting in low monitoring accuracy and easily posing a serious threat to mining safety.

[0039] According to the above embodiment of the present invention, the data acquisition module includes: a fiber grating sensor, a plurality of fiber grating sensors are evenly distributed in the high-temperature blasthole, and are used to collect optical signals within the full hole depth range, and each fiber grating sensor is connected to the fiber grating demodulator through an optical cable; and a fiber grating demodulator, which is used to convert the optical signals transmitted by the plurality of fiber grating sensors into electrical signals or digital signals to obtain temperature data of the full hole depth in the high-temperature blasthole.

[0040] The following is combined with Figure 1 and Figure 2The above embodiments of the present invention are described in detail. Figure 2 Schematic diagram of monitoring blasthole temperature according to an embodiment of the present invention.

[0041] As above Figure 1 and Figure 2 As shown, the temperature measuring points can be evenly arranged in the blasthole, that is, the fiber grating sensors and multiple fiber grating sensors can be evenly arranged to comprehensively monitor the temperature in the blasthole. In each blasthole, multiple fiber grating sensors are distributed along the depth direction of the hole to form a temperature gradient monitoring network, which can continuously monitor the temperature changes at different depths in the blasthole; in addition, the fiber grating sensor of each blasthole can be connected to a specific channel of the fiber grating demodulator through an optical cable. Although the optical cable contains a string of sensors, the entire optical cable (sensor string) is processed as a whole, corresponding to a specific channel of the demodulator, and the channel will process the data of all sensors in the optical cable; the fiber grating sensor reflects the change of temperature through the change of the grating reflection wavelength, and the fiber grating demodulator can receive these optical signals and convert them into electrical signals or digital signals that can be understood and processed, thereby demodulating the temperature data detected by the sensor.

[0042] According to the above-mentioned embodiment of the present invention, the fiber Bragg grating sensor is a sensor with high temperature resistance higher than the resistance threshold, and the high temperature resistance refers to the tolerance degree of the fiber Bragg grating sensor to temperature.

[0043] In this embodiment, the fiber grating sensor arranged in the blast hole is a high temperature resistant sensor, so that when measuring the temperature of the ultra-high temperature blast hole, the fiber grating sensor can still work normally.

[0044] According to the above embodiment of the present invention, the fiber Bragg grating demodulator is a demodulator with dust resistance higher than the dust resistance threshold and shock resistance higher than the shock resistance threshold. Dust resistance refers to the degree of prevention of dust intrusion by the fiber Bragg grating demodulator, and shock resistance refers to the degree of shock absorption of the fiber Bragg grating demodulator to reduce vibration.

[0045] In this embodiment, the fiber Bragg grating demodulator used has dustproof and shockproof characteristics, which can prevent smoke and vibration in the explosion area from affecting the fiber Bragg grating demodulator; specifically, the dustproof characteristic means that the outer shell and internal circuit design of the fiber Bragg grating demodulator can effectively prevent dust and smoke generated during mine blasting from entering the instrument. This is usually achieved by adopting sealing design, dustproof filters, and high-dust-proof materials. The dustproof design ensures that the optical components and electronic components of the demodulator are not contaminated by dust, thereby avoiding data reading errors and equipment failures; the shock-resistant characteristic means that the fiber Bragg grating demodulator can withstand certain vibrations and impacts without affecting its normal functions. In an open-pit coal mine environment, blasting operations, vibrations, ground movements, etc. may all generate vibrations, which pose a threat to the normal operation of precision electronic equipment. By using anti-vibration materials, shock-absorbing structures, internal component fixing technology, etc., the fiber Bragg grating interrogator can reduce the impact of external vibrations on its accuracy and stability, ensuring that the fiber Bragg grating sensor signal can still be accurately demodulated in a vibrating environment and the temperature data can be stably transmitted; these dust-proof and anti-vibration properties are essential to ensure the effective operation of the "full-hole depth monitoring system for high-temperature blastholes", because they ensure that the fiber Bragg grating interrogator can work stably for a long time in the harsh environment of open-pit coal mines without being interfered by external environmental factors, thereby providing reliable data support for real-time monitoring of the internal temperature of the blasthole.

[0046] According to the above embodiment of the present invention, the control module includes: a display component, which is used to display temperature data and display warning information when the borehole temperature is greater than a preset temperature threshold; and a communication component, which is used to send temperature data and warning information to a terminal device.

[0047] Optionally, the above-mentioned terminal devices may include but are not limited to: mobile phones, smart watches and other devices.

[0048] In this embodiment, the control module also includes a display component (eg Figure 1 The PC shown in FIG. 10 , of course, other devices can also be used as display components, which are not specifically limited here) and communication components (such as Figure 1 The mobile terminal shown in the figure (of course, other devices can also be used as communication components, and there is no specific limitation here) can display and transmit real-time data. For example, the PC terminal can display temperature data and warning information (when the temperature of the blasthole is greater than the preset temperature threshold and a warning information needs to be generated) on the screen and transmit it in real-time data; the mobile terminal can receive temperature data and warning information in the form of text messages, so as to timely and accurately understand the temperature information in the blasthole.

[0049] According to the above embodiment of the present invention, the instant cooling device includes: an alarm module, the alarm module is used to send out an early warning signal when receiving early warning information, and the alarm module is communicatively connected with the solenoid valve; the solenoid valve is used to start when the alarm module sends out the early warning signal, and perform a water injection operation to make the temperature of the blast hole no greater than a preset temperature threshold.

[0050] In this embodiment, as above Figure 1 As shown, the instant cooling device also includes an alarm module (i.e. Figure 1 The alarm system shown in the figure), the high temperature warning data receiving module in the alarm module can receive the temperature data sent by the transmission module, the sound and light alarm in the alarm module can send out a warning signal when receiving the warning information sent by the control module, and the alarm module is also communicated with the solenoid valve in the instant cooling device. The solenoid valve is started when the sound and light alarm in the alarm module sends out a warning signal to perform a water injection operation, thereby injecting water into the blasthole through the water outlet to cool down the inside of the blasthole.

[0051] The method embodiments provided in the embodiments of the present invention can be executed in a mobile terminal, a computer terminal or a similar computing device. Taking running on a mobile terminal as an example, Figure 3 1 is a hardware structure block diagram of a mobile terminal for a method for monitoring the full depth of a high-temperature blasthole according to an embodiment of the present invention. Figure 3 As shown, the mobile terminal may include one or more ( Figure 3 Only one is shown in the figure) a processor 302 (the processor 302 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA) and a memory 304 for storing data, wherein the mobile terminal may also include a transmission device 306 and an input / output device 308 for communication functions. It can be understood by those skilled in the art that Figure 3 The structure shown is only for illustration and does not limit the structure of the mobile terminal. Figure 3 More or fewer components as shown, or with Figure 3 Different configurations are shown.

[0052] The memory 304 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the full-hole depth monitoring method of the high-temperature blasthole in the embodiment of the present invention. The processor 302 executes various functional applications and data processing by running the computer program stored in the memory 304, that is, the above method is implemented. The memory 304 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 304 may further include a memory remotely arranged relative to the processor 302, and these remote memories can be connected to the mobile terminal via a network. Examples of the above-mentioned network include but are not limited to the Internet, corporate intranets, local area networks, mobile communication networks and combinations thereof. The transmission device 306 is used to receive or send data via a network. The above-mentioned specific examples of the network may include a wireless network provided by a communication provider of the mobile terminal. In one example, the transmission device 306 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 306 may be a radio frequency (RF) module, which is used to communicate with the Internet wirelessly.

[0053] According to an embodiment of the present invention, a method embodiment of a full-hole depth monitoring method for a high-temperature blasthole is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0054] Figure 4 FIG. 1 is a flow chart of a method for monitoring the full depth of a high-temperature blasthole according to an embodiment of the present invention. Figure 4 As shown, the method comprises the following steps:

[0055] Step S402, using a data acquisition module to collect temperature data of the entire hole depth in the high-temperature blasthole.

[0056] In this embodiment, the data acquisition module in the full-hole depth monitoring system of the high-temperature blasthole can be used to acquire the temperature data within the full-hole depth of the high-temperature blasthole.

[0057] Step S404: The temperature data is transmitted to the control module by using the transmission module, so that the temperature data is analyzed by using the control module to obtain the analysis result.

[0058] In this embodiment, the temperature data collected by the data collection module can be transmitted to the control module by using the transmission module, so that the temperature data can be analyzed by using the control module to obtain the analysis result.

[0059] Step S406, when the analysis result indicates that the borehole temperature is greater than a preset temperature threshold, a warning message is generated.

[0060] In this embodiment, if the control module parses the temperature data and the analysis result indicates that the borehole temperature is greater than the preset temperature threshold, the control module can generate corresponding warning information to indicate that the temperature in the current borehole is abnormal and corresponding measures need to be taken to deal with it.

[0061] Step S408, based on the early warning information, the instant cooling device is controlled to start the water injection program to perform the water injection operation so that the temperature of the blasthole is not greater than the preset temperature threshold.

[0062] In this embodiment, when the control module issues a warning message, the instant cooling device can be triggered to start the water injection program to perform a water injection operation to cool the blasthole so that the blasthole temperature is not greater than a preset temperature threshold.

[0063] As can be seen from the above, through the technical solution provided by the above embodiment of the present invention, a data acquisition module can be used to collect temperature data of the full hole depth in a high-temperature blasthole; the temperature data is transmitted to the control module by a transmission module, so that the control module is used to parse the temperature data to obtain an analysis result; when the analysis result indicates that the blasthole temperature is greater than a preset temperature threshold, an early warning message is generated; based on the early warning message, the instant cooling device is controlled to start the water injection program to perform the water injection operation so that the blasthole temperature is not greater than the preset temperature threshold, thereby achieving the purpose of real-time monitoring of the full hole depth temperature of the blasthole through the coordinated work of several modules in the full hole depth monitoring system, and timely issuing an early warning and taking corresponding measures to cool down the blasthole when the blasthole temperature is too high, thereby achieving the instant effect of comprehensively monitoring the temperature changes inside the blasthole by monitoring the temperature within the full hole depth range of the blasthole, thereby improving the accuracy and comprehensiveness of blasthole temperature monitoring and effectively avoiding potential safety hazards.

[0064] Therefore, the technical solution provided by the above-mentioned embodiment of the present invention solves the technical problem that when using traditional monitoring methods in related technologies to monitor high-temperature blastholes, monitoring can only be performed at certain points, and it is difficult to comprehensively monitor the temperature changes inside the blasthole, resulting in low monitoring accuracy and easily posing a serious threat to mining safety.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0066] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.
