Description

Technical Field

[0001] This disclosure relates to the technical field of preventing spontaneous combustion in coal mines, specifically to a method, apparatus, and electronic equipment for detecting spontaneous combustion in boreholes. Background Technology

[0002] Mine fires and gas disasters are two major hazards in coal mine production. Drilling boreholes within the pre-mined coal seam before extraction to drain existing gas and reduce its content is the most common and effective method for coal seam gas control. To further enhance gas extraction capabilities, integrated injection and extraction technology, also known as displacement technology, has been proposed. This involves injecting a gas with a pressure higher than the coal seam's gas pressure into a portion of the boreholes, while simultaneously extracting gas from another portion. This increases the gas flow dynamics between the injection and extraction boreholes, thereby improving gas extraction efficiency. However, if air is injected and extracted simultaneously, the risk of borehole spontaneous combustion becomes more dangerous and complex, while enhancing gas extraction.

[0003] The spontaneous combustion detection methods proposed in the relevant technologies are not applicable to the detection of spontaneous combustion in boreholes during coal seam gas extraction, resulting in poor detection results. Summary of the Invention

Thus, it can flexibly acquire corresponding target inspection data based on the borehole type to be detected, thereby ensuring the applicability of the borehole spontaneous combustion detection process to the borehole to be detected and effectively improving the detection effect of borehole spontaneous combustion.

[0026] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are used only to explain this disclosure, and should not be construed as limiting this disclosure. Rather, embodiments of this disclosure include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0027] Figure 1 This is a schematic flowchart of a borehole spontaneous combustion detection method according to an embodiment of this disclosure.

[0028] It should be noted that the main body executing the borehole spontaneous combustion detection method in this embodiment is the borehole spontaneous combustion detection device. This device can be implemented by software and / or hardware. The device can be configured in an electronic device, which may include, but is not limited to, a terminal, a server, etc. For example, the terminal may be a mobile phone, a PDA, etc.

[0029] like Figure 1 As shown, the borehole spontaneous combustion detection method includes:

[0030] S101: Determine the borehole type to be inspected, where the borehole type includes: venting holes and extraction holes.

[0031] Among them, the borehole to be tested refers to the borehole to be tested for spontaneous combustion. For example, it can be a coal seam gas extraction borehole that integrates injection and extraction. It can be divided into different types of boreholes according to its purpose, such as gas injection holes and extraction holes.

[0032] Among them, the gas injection hole refers to the borehole used in the gas extraction process to inject other gases into the coal seam at a pressure higher than that of the coal seam gas.

[0033] Among them, extraction holes refer to the boreholes used to extract gas from inside the coal seam during the gas extraction process.

[0034] It is understandable that the different uses of the injection port and the extraction port lead to differences in their characteristics, which may affect the spontaneous combustion detection process. In this embodiment of the disclosure, when the borehole type to be tested is determined, reliable reference information can be provided for obtaining the target inspection data of the borehole to be tested in the subsequent process.

[0035] S102: Based on the borehole type, obtain the target inspection data for the borehole to be inspected.

[0036] Among them, the target inspection data refers to the data used to detect whether the borehole to be inspected has spontaneously combusted.

[0037] It is understandable that the spontaneous combustion detection standards may differ for different borehole types. When the target inspection data of the borehole to be inspected is obtained according to the borehole type, the applicability of the obtained target inspection data to the borehole to be inspected can be effectively improved.

[0038] S103: Generate spontaneous combustion detection results based on the target inspection data.

[0039] The spontaneous combustion detection result refers to the detection result generated based on the target inspection data regarding whether spontaneous combustion has occurred in the borehole to be inspected. For example, it could be: spontaneous combustion will not occur, spontaneous combustion has occurred, or spontaneous combustion will occur.

[0040] In this embodiment, by determining the borehole type to be tested, which includes venting holes and extraction holes, target inspection data of the borehole to be tested is obtained based on the borehole type. Based on the target inspection data, a spontaneous combustion detection result is generated. Thus, the corresponding target inspection data can be flexibly obtained based on the borehole type to be tested, thereby ensuring the applicability of the borehole spontaneous combustion detection process to the borehole to be tested and effectively improving the detection effect of borehole spontaneous combustion.

[0041] Figure 2 This is a schematic flowchart of a borehole spontaneous combustion detection method according to another embodiment of this disclosure.

[0042] like Figure 2 As shown, the borehole spontaneous combustion detection method includes:

[0043] S201: Determine the borehole type to be inspected, where the borehole type includes: venting holes and extraction holes.

[0044] For a detailed description of S201, please refer to the above embodiments, which will not be repeated here.

[0045] S202: If the borehole to be tested is an injection hole, then in response to the borehole being in an injection state, the working temperature values ​​of multiple locations in the borehole to be tested are obtained based on the temperature measurement time interval.

[0046] Among them, the gas injection state refers to the state in which gas is injected into the coal seam in the borehole to be tested.

[0047] The temperature measurement time interval refers to the pre-set time interval for acquiring the working temperature values ​​of multiple locations in the borehole to be tested. For example, it can be 5 minutes, 10 minutes, etc. It can be flexibly configured according to the specific application scenario, and there is no restriction on it.

[0048] The operating temperature value refers to the temperature values ​​at multiple locations in the borehole under gas injection conditions.

[0049] It is understandable that the length of the borehole to be tested may be large, which may lead to differences in temperature values ​​at different locations. When the working temperature values ​​at multiple locations in the borehole to be tested are obtained based on the temperature measurement time interval, reliable reference data can be provided for the subsequent determination of the temperature distribution information of the borehole to be tested.

[0050] S203: Determine the temperature distribution information of the borehole to be inspected based on multiple operating temperature values.

[0051] Temperature distribution information can be used to indicate the overall temperature distribution of the borehole being inspected.

[0052] In this embodiment of the disclosure, when determining the temperature distribution information of the borehole to be tested based on multiple working temperature values, the average of the multiple working temperature values ​​can be obtained as the temperature distribution information, or the standard deviation of the multiple working temperature values ​​can be obtained as the temperature distribution information, and there is no limitation on this.

[0053] S204: Use temperature distribution information as target test data.

[0054] In other words, when the borehole to be inspected is a venting hole, the present invention can, in response to the borehole being in a venting state, acquire working temperature values ​​at multiple locations in the borehole based on a temperature measurement time interval, determine the temperature distribution information of the borehole based on the multiple working temperature values, and use the temperature distribution information as target inspection data. Thus, the temperature distribution information of the venting hole can be effectively obtained by combining the temperature characteristics of the venting hole in the venting state as target inspection data, thereby effectively improving the applicability of the target inspection data to the venting hole.

[0055] S205: Obtain reference inspection data for the borehole to be inspected.

[0056] Reference test data refers to test data used as reference data in the spontaneous combustion detection process.

[0057] In this embodiment of the present disclosure, when obtaining reference inspection data for the borehole to be inspected, multiple inspection data for the borehole to be inspected may be obtained, and the mode of the obtained inspection data may be used as the reference inspection data. Alternatively, a communication link may be established in advance between the execution subject of this embodiment of the present disclosure and the big data server, and then the reference inspection data for the borehole to be inspected may be obtained from the big data server. There are no limitations on this.

[0058] Optionally, in some embodiments, when obtaining reference inspection data for the borehole to be inspected, the process may involve obtaining resting temperature values ​​at multiple locations within the borehole to be inspected in response to the borehole being in a resting state. Based on these multiple resting temperature values, the temperature distribution information of the borehole in the resting state is determined, and this temperature distribution information is used as reference inspection data. This effectively combines the resting temperature values ​​at multiple locations within the borehole to be inspected in a resting state to generate reference inspection data, thereby effectively improving the accuracy of the obtained reference inspection data and its applicability to the borehole to be inspected.

[0059] The resting state can refer to the state of the borehole to be inspected before the gas injection operation is performed.

[0060] Among them, the resting temperature value refers to the temperature values ​​at multiple locations when the borehole to be tested is in a resting state.

[0061] It is understandable that the rest temperature value and the above working temperature value can be based on the same temperature acquisition location to ensure the correlation between the reference test data and the target test data.

[0062] S206: Determine the comparison results between the reference test data and the target test data.

[0063] The comparison result refers to the result obtained by comparing the reference test data and the target test data. For example, it can be the difference between the reference test data and the target test data, or it can be the ratio between the reference test data and the target test data; there are no restrictions on this.

[0064] S207: Generate spontaneous combustion detection results based on the comparison results.

[0065] In other words, after using temperature distribution information as target inspection data, this embodiment of the present disclosure can obtain reference inspection data of the borehole to be inspected, determine the comparison result between the reference inspection data and the target inspection data, and generate a spontaneous combustion detection result based on the comparison result. Thus, the comparison result between the reference inspection data and the target inspection data can be effectively combined in the spontaneous combustion detection process to effectively improve the reliability of the obtained spontaneous combustion detection result.

[0066] In this embodiment, when the borehole to be tested is a venting hole, in response to the borehole being in a venting state, the working temperature values ​​at multiple locations in the borehole are obtained based on the temperature measurement time interval. Based on these multiple working temperature values, the temperature distribution information of the borehole is determined, and this temperature distribution information is used as target inspection data. This effectively combines the temperature characteristics of the venting hole under venting conditions to obtain the temperature distribution information of the venting hole as target inspection data, thereby effectively improving the applicability of the target inspection data to the venting hole. By obtaining reference inspection data for the borehole to be tested, the comparison result between the reference inspection data and the target inspection data is determined. Based on the comparison result, a spontaneous combustion detection result is generated. Therefore, the comparison result between the reference inspection data and the target inspection data can be effectively combined during the spontaneous combustion detection process, thereby effectively improving the reliability of the obtained spontaneous combustion detection result. By responding to the borehole being inspected being in a resting state, resting temperature values ​​at multiple locations within the borehole are acquired. Based on these multiple resting temperature values, the temperature distribution information of the borehole in the resting state is determined. This temperature distribution information in the resting state is then used as reference inspection data. Thus, the resting temperature values ​​at multiple locations within the borehole being inspected in a resting state can be effectively combined to generate reference inspection data, thereby effectively improving the accuracy of the obtained reference inspection data and its applicability to the borehole being inspected.

[0067] Figure 3 This is a schematic flowchart of a borehole spontaneous combustion detection method according to another embodiment of this disclosure.

[0068] like Figure 3 As shown, the borehole spontaneous combustion detection method includes:

[0069] S301: Determine the borehole type to be inspected, where the borehole type includes: venting holes and extraction holes.

[0070] For a detailed description of S301, please refer to the above embodiments, which will not be repeated here.

[0071] S302: If the borehole to be tested is a extraction borehole, a gas sample from the borehole to be tested is obtained based on the gas extraction time interval. The gas sample includes multiple gases to be tested, and the borehole to be tested is an extraction borehole.

[0072] The gas sampling time interval refers to the pre-set time interval for acquiring gas samples from the borehole to be tested.

[0073] Here, "gas sample" refers to the gas obtained from the sampling port as a sample. "Gas to be tested" refers to the gas in the gas sample that is to be tested and processed.

[0074] It is understandable that changes in the concentration of specific gases in coal mines may affect spontaneous combustion. When gas samples are obtained from the borehole to be tested based on the gas extraction time interval, reliable reference information can be provided for subsequent borehole spontaneous combustion detection.

[0075] S303: Determine the gas concentration information of the target gas in the gas sample, where the target gas belongs to multiple gases to be detected.

[0076] The target gas refers to the gas used as the test target in this spontaneous combustion detection process.

[0077] The gas concentration information refers to the concentration of the target gas in the aforementioned gas sample. This gas concentration information can characterize the concentration of the target gas inside the coal frame.

[0078] In this embodiment of the disclosure, the target gas can be any gas that can be used for spontaneous combustion detection, such as carbon monoxide, oxygen, carbon dioxide, etc., and there is no limitation thereto.

[0079] S304: Use gas concentration information as target test data.

[0080] In other words, in this embodiment of the present disclosure, if the borehole to be tested is a sampling borehole, a gas sample in the borehole to be tested is obtained based on the gas sampling time interval. The gas sample includes multiple gases to be tested. The gas concentration information of the target gas in the gas sample is determined. The target gas is one of multiple gases to be tested. The gas concentration information is used as the target test data. Thus, the gas extraction characteristics of the sampling borehole can be effectively combined in the spontaneous combustion detection process. The gas concentration information of the target gas in the gas sample is used as the target test data to effectively improve the applicability of the obtained target test data to the sampling borehole.

[0081] S305: Generate spontaneous combustion detection results based on the target inspection data.

[0082] Optionally, in some embodiments, the target gas includes carbon monoxide and oxygen; when generating a spontaneous combustion detection result based on the target test data, a first concentration ratio between carbon monoxide and oxygen in the gas sample may be determined based on the target test data, and spontaneous combustion warning information may be generated in response to the first concentration ratio satisfying a first preset condition.

[0083] The first concentration ratio refers to the concentration ratio between carbon monoxide and oxygen in the gas sample.

[0084] The first preset condition refers to the judgment condition configured in advance for the first concentration ratio.

[0085] Among them, spontaneous combustion warning information refers to information used for issuing spontaneous combustion warnings.

[0086] Optionally, in some embodiments, the target gas includes carbon monoxide and carbon dioxide; wherein, when generating a spontaneous combustion detection result based on the target test data, a second concentration ratio between carbon monoxide and carbon dioxide in the gas sample may be determined based on the target test data, and spontaneous combustion warning information may be generated in response to the second concentration ratio satisfying a second preset condition.

[0087] The second concentration ratio refers to the concentration ratio between carbon monoxide and carbon dioxide in the gas sample. The second preset condition refers to the judgment conditions configured in advance for the second concentration ratio.

[0088] Optionally, in some embodiments, the target gas includes ethylene; wherein, when generating a spontaneous combustion detection result based on the target inspection data, the ethylene concentration information in the gas sample may be determined based on the target inspection data, and spontaneous combustion warning information may be generated in response to the ethylene concentration information meeting a third preset condition.

[0089] Here, ethylene concentration information can refer to the concentration of ethylene in the gas sample. The third preset condition refers to the judgment conditions configured in advance based on the ethylene concentration information.

[0090] In other words, in this embodiment of the present disclosure, different types of gases can be flexibly acquired as target gases when acquiring target test data, so as to adapt to the personalized coal mine gas environment and thus effectively improve the spontaneous combustion detection effect.

[0091] In this embodiment, when the borehole to be tested is a extraction borehole, a gas sample is obtained from the borehole based on the gas extraction time interval. The gas sample includes multiple gases to be tested. The gas concentration information of the target gas in the gas sample is determined. The target gas belongs to multiple gases to be tested. The gas concentration information is used as the target test data. Thus, the extraction characteristics of the extraction borehole can be effectively combined in the spontaneous combustion detection process. The gas concentration information of the target gas in the gas sample is used as the target test data to effectively improve the applicability of the obtained target test data to the extraction borehole. Based on the target test data, a first concentration ratio between carbon monoxide and oxygen in the gas sample is determined. If the first concentration ratio meets a first preset condition, a spontaneous combustion warning is generated. Based on the target test data, a second concentration ratio between carbon monoxide and carbon dioxide in the gas sample is determined. If the second concentration ratio meets a second preset condition, a spontaneous combustion warning is generated. Based on the target test data, the ethylene concentration in the gas sample is determined. If the ethylene concentration meets a third preset condition, a spontaneous combustion warning is generated. Therefore, when acquiring target test data, different types of gases can be flexibly acquired as target gases to adapt to the personalized coal mine gas environment, thereby effectively improving the spontaneous combustion detection effect.

[0096] For example, such as Figure 8 As shown, Figure 8 This is a schematic diagram of a borehole spontaneous combustion detection process according to an embodiment of the present disclosure, which includes:

[0097] 1) Based on the functional division of the borehole, different monitoring methods for spontaneous combustion of the borehole are selected. The temperature method is used to monitor the gas injection hole, and the gas method is used to monitor the extraction hole.

[0098] 2) Connect the borehole spontaneous combustion monitoring system for the integrated gas extraction process, arrange the distributed temperature measurement fiber optic cable 404 in the gas injection hole 402 and connect it to the signal transmission cable 412. The signal transmission cable 412 is connected to the temperature analysis device 407 through the temperature analysis device interface 4071. The extraction hole 403 is connected to the extraction main pipeline 411 through the extraction manifold 413. Arrange the gas collection conduit 414 on the extraction manifold 413. Connect the gas collection conduit 414 connected to different extraction holes 403 to multiple gas collection conduit connection ports 4081. Enter the gas negative pressure acquisition device 408 through the multi-way gas switching valve 4082. The gas negative pressure acquisition device 408 is connected to the gas component content analysis device 409 through the gas outlet 4084 through the flexible rubber tube 415 and the flexible rubber tube connection port 4091.

[0099] 3) Turn on the temperature analysis device 407, the gas negative pressure acquisition device 408 and the gas component content analysis device 409, and set the flow rate of the gas negative pressure acquisition device to 10L / min.

[0100] 4) Before starting the air injection, the temperature T at each measuring point is measured every 1m using the distributed temperature measuring fiber optic cable 404 and the temperature analysis device 409. i The total number of measuring points is N. The mean temperature MN0 and standard deviation SD0 along the borehole are calculated.

[0101]

[0102]

[0103] In the formula, MN0 is the average initial temperature along the borehole during gas injection, in °C; T i is the initial temperature at each measuring point inside the borehole, in °C; N is the number of boreholes; SD0 is the difference in initial temperature along the borehole during gas injection.

[0104] 5) After the air injection is started, the temperature at each measuring point is obtained by the temperature value display module 4073 every 5 minutes. And calculate the average borehole temperature MN j and standard deviation SD j The calculation method refers to the calculation method of MN0 and SD0 in formulas (1) and (2).

[0105] 6) The temperature discrimination criterion is: ①SD j ≥1.2SD0, ②MN j If ≥MN0+5, any of the above conditions are met, and the hole is considered to be in a state of spontaneous combustion; otherwise, the drilling is considered to be normal.

[0106] 7) Every 5 minutes, the gas is collected through the negative pressure gas collection device 408, powered by the negative pressure pump 4083, and the gas in each extraction manifold 413 is collected through the multi-way gas switching valve 4082.

[0107] 8) The acquired gas is sent into the gas component content analysis device 409 through the flexible rubber tube connection port 4091. The gas is then separated by the gas-water separation chamber 4092 to remove a large amount of liquid water that may be carried in the gas. The gas is then dried by the gas purification and drying chamber 4093 to remove any dust and other impurities that may be present. The gas is then analyzed by the gas multi-gas component content detection component 4094, and the concentration of O2, CO, CO2, and C2H4 gas in the gas is obtained by the gas concentration display module 4095.

[0108] 9) The criteria for judging gas indicators are: ① I1 continuously increases for more than 5 consecutive tests; ② I2 continuously increases for more than 5 consecutive tests; ③ C2H4 component is present in the gas. The spontaneous combustion status of the extraction borehole is analyzed using these gas indicator criteria. If any of the above conditions are met, the borehole is considered to have spontaneous combustion; otherwise, the borehole is considered normal.

[0109]

[0110]

[0111] In the formula, I1 and I2 are gas indices, and C CO , and These represent the concentrations of CO, O2, and CO2 gas, respectively, 10 -6 .

[0112] 10) Temperature and gas analysis are carried out simultaneously. Repeat steps 4-6 and 7-9 above respectively to achieve dynamic monitoring of the spontaneous combustion status of the injection and extraction holes. If the drilling status is abnormal, the injection gas flow rate needs to be controlled by adjusting the injection pressure regulating valve 405 and the extraction pressure regulating valve 406. If necessary, other spontaneous combustion control measures should be taken.
