Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, and in particular to an intelligent all-round multi-data borehole monitoring device and borehole monitoring unit for mining. Background Technology

[0002] Currently, coal mines mainly employ strike-longwall or dip-longwall fully mechanized mining methods, with layered or top-coal caving mining used for thick coal seams. These mining conditions lead to the extensive use of protective pillars, leaving behind large amounts of unmined coal resources. This becomes the dominant factor in stress concentration between working faces and the primary cause of spontaneous combustion in goafs. Therefore, the rational monitoring of pillar stress distribution and goaf spontaneous combustion has become a pressing production challenge that needs to be addressed.

[0003] In the existing technology, the main problems with coal pillar stress monitoring and goaf spontaneous combustion monitoring are as follows: (1) Monitoring data needs to be collected by operators at each station underground, which increases the workload of operators and wastes labor; (2) Most existing monitoring equipment only collects coal pillar stress between working faces, and the temperature and humidity inside the coal pillar are not monitored, resulting in the singleness and limitation of the collected data, which is of little help to the construction of intelligent mines in the future; (3) The collection of coal pillar stress data is mainly aimed at the front of the working face or the side of the unmined working face, and no effective collection method has been formed for the stress in the goaf; (4) If the humidity and natural tendency of the coal body in the goaf are to be collected, the plastic pipe equipment needs to be buried in the goaf in advance, which further increases the workload. At the same time, it is not possible to collect data in real time, and there are data intervals and stage collection, which increases the error of the monitoring data. All of the above problems will lead to difficulties in obtaining monitoring data, large errors, and difficulty in real-time collection of working face stress, humidity and temperature monitoring data during the intelligent construction of mines.

[0004] Currently, in order to monitor the stress, humidity and temperature of coal pillars between working faces, equipment such as borehole stress gauges in coal pillars, plastic pipes and underground environmental humidity detectors are mainly used. However, considering that the above equipment has problems such as difficulty in monitoring data in goaf areas, incomplete monitoring data and data intervals, it is difficult to form a comprehensive, multi-data collection with minimal human intervention.

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0027] The following is combined Figures 1-5 This invention describes an intelligent, all-around, multi-data borehole monitoring device for mining (this invention can be simply referred to as a "borehole monitoring device" or "device"), and describes a borehole monitoring equipment of this invention (this invention can be simply referred to as a "device") based on the borehole monitoring device.

[0028] like Figure 1 and Figure 2 As shown, the borehole monitoring device of this embodiment includes a support pipe 3 and several monitoring stacked modules 4. The support pipe 3 is suitable for axial insertion into the area to be measured. The support pipe 3 provides overall support for the device at the mandrel position. The device as a whole can be installed axially within the area to be measured, especially inside a coal pillar in a mine, thereby ensuring that the device can still collect various data for a long time in the goaf, effectively solving the data collection problem in the goaf. Several monitoring stacked modules 4 form a ring structure and are sleeved on the outside of the support pipe 3. Each monitoring stacked module 4 includes a temperature and humidity monitoring component 1 and a stress monitoring component 2. The temperature and humidity monitoring component 1 and the stress monitoring component 2 are arranged radially from the outside to the inside of the support pipe 3. By arranging several monitoring stacked modules 4 into a ring structure and sleeved on the outside of the support pipe 3, the device is constructed as a cylindrical structure, and the temperature and humidity monitoring component 1 and the stress monitoring component 2 arranged around the circumference of the device achieve comprehensive monitoring of the temperature, humidity, and stress conditions inside the borehole to be measured.

[0029] In some embodiments, such as Figure 1 , Figure 2 and Figure 3As shown, each monitoring stack module 4 includes a temperature and humidity monitoring installation area and a stress monitoring installation area. The temperature and humidity monitoring component 1 includes several temperature monitoring units 7 and several humidity monitoring units 8. The temperature and humidity monitoring installation area and the stress monitoring installation area are arranged radially from the outside to the inside of the support tube 3. That is, the monitoring stack module 4 can form a ring structure. The ring structure is divided into two installation areas from the outside to the inside. The outermost installation area is the temperature and humidity monitoring installation area, and the temperature and humidity monitoring component 1 is installed in this temperature and humidity monitoring installation area. That is, all temperature monitoring units 7 and humidity monitoring units 8 of the same temperature and humidity monitoring component 1 are installed in the same temperature and humidity monitoring installation area. The specific arrangement structure is shown below. The inner layer is the stress monitoring installation area, and the stress monitoring component 2 is installed in this stress monitoring installation area. Thus, the monitoring stack module 4 forms two ring installation areas, ensuring that each monitoring stack module 4 can synchronously monitor temperature, humidity, and stress data for the same location.

[0030] In some specific embodiments, such as Figure 1 and Figure 3 As shown, preferably, several monitoring stacked modules 4 are evenly divided along the circumference of the support tube 3. Thus, the temperature and humidity monitoring installation area and the stress monitoring installation area are both constructed as at least a portion of a ring structure. In this embodiment, the device preferably includes eight sets of monitoring stacked modules 4, which are arranged in a fan shape to form a ring structure. The included angle between the centers of each monitoring stacked module 4 is 45 degrees, thereby achieving omnidirectional monitoring of stress, temperature, and humidity in 45-degree angle units. Utilizing the stress monitoring component 2 and temperature and humidity monitoring component 1, which are radially distributed from the inside out in the monitoring stacked modules 4, accurate monitoring of relevant data within the 45-degree angle range is achieved. This ensures that the eight sets of monitoring stacked modules 4 forming the ring structure can achieve accurate monitoring of relevant data from all 360 degrees, reducing monitoring omissions and improving the monitoring range and accuracy.

[0031] It should be noted that the number of the above-mentioned monitoring stacked modules 4 is not limited to eight, but can also be one or more. The number of monitoring stacked modules 4 should correspond to the degree of the included angle between the center and the circle, and all monitoring stacked modules 4 should be able to form a ring structure and be fitted outside the support tube 3.

[0032] In some specific embodiments, in order to improve the monitoring range and the accuracy of monitoring data, such as Figure 1As shown, the temperature and humidity monitoring component 1 preferably includes at least one set of temperature and humidity monitoring modules 6. If the temperature and humidity monitoring modules 6 are a set, the temperature and humidity monitoring modules 6 are installed as a whole in the temperature and humidity monitoring installation area, ensuring that the monitoring area formed by the temperature and humidity monitoring modules 6 can cover the fan-shaped area corresponding to the included angle of the center of the monitoring stacked module 4, and the monitoring areas formed between adjacent monitoring stacked modules 4 can overlap with each other to avoid missing monitoring areas.

[0033] It should be noted that there can be two or more temperature and humidity monitoring modules 6. These modules can be installed in layers, arranged continuously along the axis of the device, or arranged circumferentially along the device. The configuration simply needs to ensure that the monitoring area covers the fan-shaped region and that there are no unmonitored areas along the circumference of the device.

[0034] In some embodiments, each temperature and humidity monitoring module 6 in the above-described temperature and humidity monitoring assembly 1 includes a plurality of temperature monitoring units 7 and a plurality of humidity monitoring units 8. The temperature monitoring units 7 in the same temperature and humidity monitoring module 6 can have various layout structures; similarly, the humidity monitoring units 8 in the same temperature and humidity monitoring module 6 can have various layout structures. For example, all temperature monitoring units 7 are arranged along the axial direction of the support tube 3, and all humidity monitoring units 8 are arranged along the axial direction of the support tube 3. Each temperature monitoring unit 7 is arranged on one circumferential side of each humidity monitoring unit 8.

[0035] In some specific embodiments, such as Figure 1 and Figure 4As shown, all temperature monitoring units 7 in the same temperature and humidity monitoring module 6 include a first temperature monitoring subunit 7-1 and a second temperature monitoring subunit 7-2. The first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2 are arranged along the axial direction of the device. Preferably, the first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2 are respectively located at both ends of the device, that is, a certain distance is spaced between the first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2, so that the device has a certain axial length range for temperature monitoring at the same location, increasing the accuracy of axial temperature monitoring. Similarly, all humidity monitoring units 8 in the same temperature and humidity monitoring module 6 include a first humidity monitoring subunit 8-1 and a second humidity monitoring subunit 8-2. The first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2 are arranged along the axial direction of the device. Preferably, the first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2 are respectively located at both ends of the device, that is, a certain distance is spaced between the first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2, so that the device has a certain axial length range for humidity monitoring at the same location, increasing the accuracy of axial humidity monitoring. Based on the above structure, the first temperature monitoring subunit 7-1 is located on one side of the first humidity monitoring subunit 8-1, and the second temperature monitoring subunit 7-2 is located on one side of the second humidity monitoring subunit 8-2. This ensures that temperature and humidity data can be monitored synchronously at the same circumferential position, thereby improving the matching and accuracy of temperature and humidity data, which is of great significance for real-time data analysis.

[0036] It should be noted that, in the apparatus described in the embodiments of the present invention, such as Figure 2 As shown, the temperature monitoring units 7 and humidity monitoring units 8 in the same temperature and humidity monitoring module 6 can also be arranged along the axial direction of the support tube 3, thereby reasonably dividing the monitoring range for temperature and humidity monitoring. Specifically, all temperature monitoring units 7 are arranged circumferentially, and all humidity monitoring units 8 are arranged circumferentially. This arrangement ensures accurate and reliable real-time monitoring of temperature and humidity data at all locations around the device.

[0037] In some specific embodiments, such as Figure 1As shown, each stress monitoring installation area in the monitoring stack module 4 is equipped with at least one set of stress monitoring modules 5. If there is only one set of stress monitoring modules 5, then the stress monitoring modules 5 are laid out throughout the entire stress monitoring area; if there are multiple sets of stress monitoring modules 5, then all stress monitoring modules 5 are preferably laid out radially in the stress monitoring area, or installed along the axial direction of the device in the stress monitoring area. This arrangement ensures that the stress monitoring modules 5 are located in the inner layer of the temperature and humidity monitoring modules 6, thereby enabling real-time monitoring of temperature, humidity, and stress data of the area to be measured in the same location simultaneously.

[0038] It should be noted that the aforementioned borehole monitoring device may also consist of only one monitoring stack module 4. This monitoring stack module 4 is annularly mounted on the outside of the support tube 3. The monitoring stack module 4 is divided into two annular installation areas from the outside in, corresponding to the aforementioned temperature and humidity monitoring installation area and stress monitoring installation area, respectively. All the aforementioned temperature monitoring units 7 and all the aforementioned humidity monitoring units 8 are installed in the temperature and humidity monitoring installation area according to any of the aforementioned layout structures. All the aforementioned stress monitoring units are evenly distributed along the circumference of the device in the innermost stress monitoring installation area.

[0039] In some embodiments, such as Figure 1 and Figure 2 As shown, the borehole monitoring device also includes a flexible protective shell 9, a temperature and humidity monitoring protective shell 12, and a stress monitoring protective shell 13. The flexible protective shell 9 is fitted and fixed to the outside of the annular structure. The flexible protective shell 9 is used to protect the overall deformation resistance of the monitoring equipment, while reducing the interference and damage of coal ash to the equipment. Preferably, one end of the flexible protective shell 9 is provided with a connector 10, and the other end of the flexible protective shell 9 is provided with a connection port 11 adapted to the connector 10. In the assembly process of continuously assembling multiple borehole monitoring devices to form a borehole monitoring device, the connector 10 and connection port 11 of adjacent devices are used for assembly, thereby realizing quick assembly and disassembly of multiple devices, improving the efficiency of disassembly and assembly in use, and thus improving the flexibility of equipment assembly. The temperature and humidity monitoring protective shell 12 is fitted and fixed to the outside of all temperature and humidity monitoring installation areas and connected to the inside of the flexible protective shell 9. The temperature and humidity monitoring protective shell 12 is preferably made of a rigid material, and its main purpose is to protect the temperature and humidity monitoring component 1 from deformation and damage under high stress conditions. The stress monitoring protective shell 13 is fixed outside all stress monitoring installation areas and connected between all temperature and humidity monitoring installation areas and the support pipe 3. The rigid protective shell of the stress monitoring component 2 is preferably made of a rigid material. It is used to protect the stress monitoring module 5. The stress monitoring module 5 has a high resistance to deformation, but it needs the protection of the stress monitoring protective shell 13 in case of emergencies, which plays an emergency protection role.

[0040] In some embodiments, such as Figure 5As shown, at least one of the temperature and humidity monitoring protective housing 12 and the stress monitoring protective housing 13 is equipped with a return spring 17. During various data acquisition processes, the temperature and humidity monitoring component 1 and the stress monitoring component 2 in any borehole monitoring device may be displaced, or even the entire monitoring stack module 4 may be displaced. At this time, the return spring 17 in the monitoring stack module 4 can reset the temperature and humidity monitoring component 1 and the stress monitoring component 2, thereby effectively avoiding data acquisition errors and reducing equipment damage.

[0041] In some embodiments, such as Figure 2 As shown, the support tube 3 contains a battery. As the main support, the support tube 3 serves to connect the device and provide a rigid frame for the device and even the entire equipment. It also provides storage space and protection for the power supply 16 installed inside.

[0042] In some embodiments, such as Figure 2 As shown, the borehole monitoring device also includes a GPS positioning and ranging unit 14 and a data acquisition and transmission unit 15. The GPS positioning and ranging unit 14 is connected to one axial end of the support pipe 3. The data acquisition and transmission unit 15 is connected to the other axial end of the support pipe 3. This borehole monitoring device has data acquisition and transmission functions. After the first monitoring device acquires data, the data acquisition and transmission unit 15 transmits the data to the second device, and then sequentially to the device closest to the coal face. After the transmission is completed, the data will be transmitted to the device in the nearest borehole, until the data is transmitted to the device in the farthest borehole, and the data will be uploaded to the mine ring network and the group dispatch room, solving the problem of manual data collection and alleviating the labor intensity of the workers. That is, the stress monitoring component 2 and the humidity and temperature monitoring component mentioned above can achieve data acquisition frequency through the GPS positioning and ranging unit 14 and the data acquisition and transmission unit 15, and the built-in battery can complete long-term data monitoring. Therefore, after the equipment composed of this device is installed in the coal pillar, it can still collect data for a long time in the goaf, effectively improving the real-time and continuous data collection in the goaf.

[0043] It should be noted that the operating sequence of this device is as follows.

[0044] First, power supply 16 provides power. The GPS positioning and ranging unit 14 monitors the distance and depth of the area to be measured. In the monitoring stack module 4, for each temperature monitoring unit 7 of the temperature and humidity monitoring component 1, the first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2 begin data acquisition according to the initial settings after being powered on; similarly, for each humidity monitoring unit 8 of the temperature and humidity monitoring component 1, the first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2 begin data acquisition according to the initial settings after being powered on. The stress monitoring module 5 in the stress monitoring component 2 is simultaneously powered on and begins data acquisition according to the initial settings. During and after data acquisition, the relevant data is transmitted to the next device via the data acquisition and transmission unit 15.

[0045] The temperature data monitoring process is as follows: After the power supply 16 is powered on, the first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2 in the aforementioned monitoring stacked module 4 can start monitoring the coal body temperature according to the set value. In this embodiment, omnidirectional temperature monitoring is achieved in units of 45 degrees. The first temperature monitoring subunit 7-1 and the second temperature monitoring subunit 7-2 are complementary monitoring units, which can improve the accuracy of temperature monitoring. After the temperature data acquisition is completed, the data is transmitted to the next device's data acquisition and transmission unit 15 through the data acquisition and transmission unit 15, until finally transmitted to the mine ring network and then sequentially to the mine dispatch room and the central control console.

[0046] The humidity data monitoring process is as follows: After the power supply 16 is powered on, the first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2 in the aforementioned monitoring stacked module 4 can start monitoring the humidity of the coal body according to the set value. In this embodiment, omnidirectional humidity monitoring is achieved in units of 45 degrees. Among them, the first humidity monitoring subunit 8-1 and the second humidity monitoring subunit 8-2 are complementary monitoring units, which can improve the accuracy of humidity monitoring. After the humidity data is collected, it is transmitted to the next device's data acquisition and transmission unit 15 through the data acquisition and transmission unit 15, until it is finally transmitted to the mine ring network and then sequentially transmitted to the mine dispatch room and the central control station.

[0047] The stress data monitoring process is as follows: For the stress monitoring component 2 in the monitoring stack module 4, the stress monitoring module 5 starts monitoring the stress of the coal body in the test area according to the set value, thereby realizing all-round stress monitoring in 45-degree angle units. After the stress data acquisition is completed, the data is transmitted to the data acquisition and transmission unit 15 of the next device through the data acquisition and transmission unit 15, until finally transmitted to the mine ring network and then sequentially transmitted to the mine dispatch room and the central control station.

[0048] The data transmission and alarm process is as follows: After the power supply 16 is powered on, the specific data acquisition frequency and limit alarm data are set for the data acquisition and transmission unit 15. When the set value is reached, the device transmits alarm data to the central control to trigger the central control alarm and prevent sudden disasters.

[0049] It should be noted that if a problem occurs in one set of devices during data transmission, the data will be transmitted to the nearest device until all data transmission is completed.

[0050] It should be noted that when selecting the data acquisition frequency of the data acquisition unit, the relevant components in any monitoring stack module 4 of the entire equipment can be set through any single device, which greatly solves the inconvenience of data acquisition and setting. Furthermore, all the above operations can be finely adjusted through the data acquisition and transmission unit 15, and the feedback information can be transmitted from the mine ring network to the surface. Simultaneously, adjustments can be made on the ground computer to achieve equipment self-monitoring and alarm, thus realizing intelligent operation.

[0051] The present invention also provides a borehole monitoring device. This device includes several of the aforementioned borehole monitoring units. These borehole monitoring units are connected axially. By configuring the aforementioned intelligent omnidirectional multi-data borehole monitoring device for mining, this borehole monitoring device possesses all the advantages of the aforementioned intelligent omnidirectional multi-data borehole monitoring device for mining, which will not be elaborated further here.

[0052] The borehole monitoring device and equipment provided by this invention can further optimize the repetitive work of data collection during on-site data monitoring, improve the accuracy of data collection, realize the collection of data in the goaf, solve the difficulty of monitoring data in the goaf, and greatly ensure the safe and efficient mining of the mine. Furthermore, it possesses at least the following advantages: By axially connecting multiple sets of devices, the flexibility of equipment installation and combination is improved, avoiding the difficulties of flexibly installing equipment length according to site conditions, resulting in equipment waste or incomplete data collection due to insufficient installation depth; through the step-by-step signal transmission function, remote control and remote data acquisition are realized, solving the previous problem of difficult data collection in goaf areas, improving the monitoring of stress, temperature, and humidity data in goaf areas, filling the gaps in goaf area data collection, and enabling early prediction of sudden disasters in goaf areas, such as high stress concentration and coal body natural disasters; by setting a single set of devices to a 1-meter-long structure and enabling axial connection of multiple sets of devices at the tail, the flexibility of the equipment is greatly improved, while avoiding material waste; the device and equipment realize remote operation settings and remote data acquisition through the data acquisition and transmission unit 15. The equipment transmits feedback information from the mine ring network to the ground according to the set threshold, realizing self-alarm and reducing the occurrence of sudden disasters. Based on the above functions, intelligent monitoring and transmission of equipment are realized.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
