Description

Technical Field

[0001] The present application relates to the technical field of digital electronic detonator initiation control, and in particular to a digital electronic detonator initiation control method. Background Art

[0002] In recent years, the use of digital electronic detonators for blasting operations has become increasingly common, particularly in underground tunnels and other areas where manual blasting is unsuitable. Digital electronic detonator blasting utilizes a digital electronic detonator placed in the blasthole. A wireless transceiver connected to the digital electronic detonator establishes signal communication with the blasting control terminal, enabling delay adjustment and blasting command control for precise blasting operations.

[0003] Of course, most current digital electronic detonator blasting control systems utilize a one-to-one fixed-point control system, where one wireless transceiver corresponds to one digital electronic detonator. This approach often fails to efficiently achieve precise blasting control, increasing equipment costs and the workload of coordinating and adjusting delay control between different blasting points. Furthermore, since digital electronic detonators require pins to connect to wireless transceivers for signal control, and to ensure energy is not lost after the detonator explodes in the blasthole, the blasthole must be sealed after the detonator is buried. This can affect the wireless transceiver's reception of wireless signals. Therefore, the configuration of the wireless transceiver requires careful analysis and consideration.

[0004] Therefore, designing a digital electronic detonator detonation control method that can reasonably pair the wireless transceiver with multiple digital electronic detonators while also enabling the wireless transceiver to block the blasthole and ensure better blasting effect is an urgent problem to be solved. Summary of the Invention

[0005] The present invention aims to provide a method for controlling the initiation of digital electronic detonators. By analyzing initiation parameter data, the method determines the placement and required number of digital electronic detonators, and then rationally groups the delayed initiation according to the initiation delay time data to ensure the effectiveness of the delayed initiation. This method also enables wireless transceivers to be paired with multiple digital electronic detonators according to different groups, thereby improving the accuracy of delayed blasting while reducing equipment costs and achieving better blasting results. Furthermore, by fully considering the initiation parameter data and the material data of the digital electronic detonator installation location, the parameters for installing the wireless transceiver for blasthole blocking are determined. This effectively ensures that the wireless transceiver blocks the blasthole, preventing damage to the wireless transceiver caused by environmental influences when left outside the blasthole. Furthermore, the method facilitates the use of the wireless transceiver for blasthole blocking, achieving a better blocking effect and ensuring the effectiveness of the blasting.

[0006] In a first aspect, an embodiment of the present application provides a digital electronic detonator detonation control method, comprising obtaining detonation parameter data, performing detonation analysis, and determining the installation position and the number of digital electronic detonators to be installed; obtaining detonation delay time data according to the detonation parameter data, and grouping the digital electronic detonators according to the detonation delay time data to form delayed detonation group data; opening blastholes in groups according to the installation position of the digital electronic detonator and the delayed detonation group data, and reserving installation space for a wireless transceiver; obtaining material data of the installation position of the digital electronic detonator, and performing mechanical analysis in combination with the detonation parameter data, and installing the wireless transceiver using a detonator installation device according to the analysis results; pairing and connecting the wireless transceivers in each group according to the delayed detonation group data; obtaining pairing data information for inspection and confirmation, and performing delayed detonation according to the inspection results.

[0007] In an embodiment of the present application, the method determines the buried location and corresponding required number of digital electronic detonators by analyzing the detonation parameter data, and performs reasonable delayed detonation grouping based on the detonation delay time data to ensure the effectiveness of the delayed detonation. This also allows the wireless transceiver to be paired with multiple digital electronic detonators according to different groups, thereby improving the accuracy of delayed blasting while saving equipment costs and achieving better blasting results. In addition, based on the full consideration of the detonation parameter data and the material data of the digital electronic detonator installation location, the parameters for the wireless transceiver to block the blasthole are determined, which can effectively ensure that the wireless transceiver blocks the blasthole, that is, avoids the situation where the wireless transceiver is left outside the blasthole and is damaged by environmental influences. It also facilitates the use of the wireless transceiver for blasthole blocking, achieving better blocking to ensure the blasting effect.

[0008] As a possible implementation method, material data of the installation position of the digital electronic detonator is obtained, and a mechanical analysis is performed in combination with the initiation parameter data. According to the analysis results, a detonator installation device is used to install the wireless transceiver, including: obtaining the explosion pressure value according to the initiation parameter data; determining the effective blocking and holding area according to the pressure value and the ultimate force condition of the wireless transceiver; determining the installation parameter data of the wireless transceiver according to the material data of the installation position of the digital electronic detonator and in combination with the effective blocking and holding area; and installing the wireless transceiver using the detonator installation device according to the installation parameter data.

[0009] In the embodiments of the present application, determining the blocking force exerted by a wireless transceiver on a blasthole is crucial. This blocking force must be sufficient to withstand the impact pressure generated by the explosion of the digital electronic detonator during blasting. Therefore, during analysis, the impact pressure of the explosion must be determined based on the detonation parameter data. Furthermore, the effective support area of ​​the material at the blasthole that the wireless transceiver must utilize during blocking, combined with the structural strength of the wireless transceiver and the material data at the blasthole location, must be determined to prevent the wireless transceiver from being pushed out of the blasthole during the blast. The effective support area can be accurately calculated based on the impact pressure and the structural strength of the wireless transceiver. This allows the wireless transceiver to be adjusted during installation based on its mounting method and structure to ensure that the support area is no less than the calculated theoretical effective support area.

[0010] As a possible implementation method, the wireless transceiver includes a blocking shell, a blocking ball head, a sealing filler, a signal receiving module, a signal processing module, a signal output module and an output connection line; one end of the blocking shell is sequentially provided with a blocking groove, a receiving groove and a filling groove that are interconnected, and a communication hole is provided at the bottom of the filling groove; a loosening cavity, a deformation cavity and a supporting cavity are sequentially formed in the blocking groove from the end close to the receiving groove to the end away from the receiving groove; the diameters of the loosening cavity, the deformation cavity and the supporting cavity decrease in sequence; the blocking ball head is located in the blocking groove, and the blocking ball head The diameter of the body is adapted to the diameter of the loose cavity; a guide column is formed at one end of the blocking ball head body, and the guide column is slidably arranged in the accommodating groove; an adjusting threaded hole and a device hole that are interconnected are respectively opened on the blocking ball head body along the axis of the guide column; the adjusting threaded hole is located at the end away from the guide column; the signal receiving module, the signal processing module and the signal output module are connected in sequence and are all arranged in the device hole; the sealing filler is arranged in the filler groove; one end of the output connecting line is connected to the signal output module, and the other end passes through the sealing filler and is connected to the wiring terminal located at the end of the communication hole.

[0011] In the embodiment of the present application, the installation and adjustment of the effective support area of ​​the wireless transceiver is closely related to the structure of the wireless transceiver. This solution provides a structure for a wireless transceiver. Under this structure, the blocking shell is the main body for achieving the adjustment of the effective support area. Since the diameter of the blocking groove is smaller than the diameter of the blocking ball body at one end of the blocking shell, when the blocking ball body is pulled out toward the borehole using the detonator installation device, the blocking shell will be squeezed, causing the blocking shell to squeeze the borehole wall, and then the blocking shell will be embedded in the borehole wall. At this time, the end of the blocking shell forms an effective support surface with the material of the borehole wall. Of course, according to the calculated theoretical effective support area, the movement distance of the blocking ball body can be adjusted, and then the area size of the effective support surface can be adjusted to match the theoretical calculated value. The effective abutment area formed by the end of the plugging shell is closely related to the moving distance of the plugging ball. After establishing the relationship between the two, the relationship between the moving distance of the plugging ball and the threaded tightening torque required for the threaded connection movement is further analyzed. In this way, precise installation control can be achieved by using the detonator installation device in conjunction with the adjustment threaded hole on the plugging ball according to the threaded torque value. Of course, it should be noted that although the blast hole is effectively blocked by the wireless transceiver, the detonator installation device will be separated from the plugging ball after installation. In this way, the signal receiving module located in the device hole can communicate with the controller through the adjustment threaded hole without hindrance, which can ensure that the wireless transceiver can receive the signal from the controller in a timely manner. In addition, for the plugging ball, the device hole and the adjustment threaded hole are opened on the axis. Since they are both hole-shaped grooves, the internal force is relatively evenly distributed, avoiding stress concentration and reducing the structural strength of the wireless transceiver, ensuring that its blocking function can be stably achieved during the installation and blasting process.

[0012] As a possible implementation method, multiple stop steps are formed on the wall of the deformation cavity along the axis; the drop surface of the stop step faces the supporting cavity; in the direction from the loose cavity to the supporting cavity, the minimum diameter of the stop step is between the minimum diameter and the maximum diameter of the next adjacent stop step.

[0013] In the embodiments of the present application, it is understood that the detonator installation device first adjusts the threaded hole to pull the blocking ball, thereby allowing the wireless transceiver to stably block the blasthole. Once the installation conditions are met, the detonator installation device needs to be removed, that is, the threads need to be rotated in the opposite direction to loosen the detonator installation device from the threaded adjustment hole. This may cause the blocking ball to move back. Therefore, to prevent the blocking ball from moving back, a stop step is provided on the deformation chamber. The drop surface of the stop step serves as a support surface for the blocking ball to move back, effectively preventing the blocking ball from moving back. Of course, considering that the movement of the blocking ball causes the effective support area on the end of the blocking shell to continuously change, the diameter of adjacent stop steps needs to continuously change. The minimum diameter of the stop step is between the minimum and maximum diameters of the next adjacent stop step to effectively ensure this continuous change. At the same time, it also prevents the blocking ball from continuously pressing against the blocking shell, thereby preventing damage to the threads in the threaded adjustment hole due to long-term stress.

[0014] As a possible implementation method, a guide rail is protruded on the groove wall of the accommodating groove around its axis; a guide groove is opened on the guide column; and the guide groove and the guide rail are slidably matched.

[0015] In the embodiment of the present application, the primary movement of the plugging ball is sliding. The most important thing to avoid is rotation about its own axis. This would cause the detonator mounting device to change its fit with the threaded adjustment hole, directly affecting the thread tightening torque, and thus failing to achieve the theoretical effective contact area, resulting in poor sealing. Therefore, a guide rail is provided in the receiving slot to limit the rotational movement of the plugging ball about its own axis, further ensuring that the installation is effective and that the wireless transceiver effectively blocks the blasthole.

[0016] As a possible implementation manner, the length of the output connection line located in the accommodating groove is not less than the maximum distance that the blocking ball body moves in the blocking groove.

[0017] In the present embodiment, it is understood that because the movement of the plugging ball increases the distance between the guide post and the filler slot, it is necessary to ensure that the output connecting wire cannot be broken after the plugging ball moves. A length of the output connecting wire must be reserved in this area, and the reserved length is sufficient to ensure that the plugging ball will not be broken when it reaches the farthest end of its sliding motion.

[0018] As a possible implementation method, the blocking shell is located in the blasthole; the blocking shell is penetrated inward relative to the blasthole mouth, and the penetration distance is determined according to the detonation parameter data and the material data of the digital electronic detonator installation position.

[0019] In the embodiment of the present application, it is understandable that the wireless transceiver must not only communicate wirelessly with an external controller but also ensure the blocking of the blasthole. Since the threaded adjustment hole that connects the device hole to the outside world is provided on the blocking ball head, effective communication between the signal receiving module and the controller can be ensured. In this way, it is only necessary to consider whether the wireless transceiver can stably block the blasthole. Since the end of the blocking shell is an important position for generating an effective supporting surface, the effective supporting force it receives comes from the installation position material in contact with it. If the wireless transceiver is too close to the orifice of the blasthole, the material cannot provide sufficient supporting force, which may cause the orifice of the blasthole to collapse. Therefore, in order to avoid this situation, it is necessary to combine the data of the installation position material and the detonation parameter data to determine the depth of the wireless transceiver entering the blasthole.

[0020] As a possible implementation method, the detonator installation device includes an orifice supporting plate, a supporting rod and a driver; a through hole is opened on the orifice supporting plate; one end of the supporting rod is connected to the driver, and the other end passes through the through hole; a threaded connector is formed on the end of the supporting rod close to the wireless transceiver; the threaded connector cooperates with the adjustment threaded hole on the blocking ball body to realize the connection between the supporting rod and the blocking ball body; the orifice supporting plate contacts the orifice surface of the blast hole, and a supporting boss is formed on the end of the orifice supporting plate close to the blast hole; the supporting boss is embedded in the blast hole and supports the blocking shell.

[0021] In the embodiment of the present application, the main functions of the detonator installation device are, on the one hand, to stabilize the borehole to avoid damage to the borehole during the installation of the wireless transceiver, and on the other hand, to pull the blocking ball to effectively install the wireless transceiver. During the installation of the wireless transceiver, due to the effect of the borehole support plate, it can be ensured that the support rod does not move along the axis, so that the blocking ball can be moved along the axis through threaded engagement to achieve support installation. When the support rod rotates to reach the set thread torque value, it is necessary to rotate the support rod in the opposite direction. At this time, the borehole support plate no longer supports the borehole surface, and the support rod moves along the axis during the loosening process, thereby loosening the support rod and the blocking ball, thus completing the installation of the wireless transceiver. This installation method is simple and efficient.

[0022] As a possible implementation method, a positioning ring groove is opened on the hole wall of the through hole around the axis thereof; a limiting ring is protruded on the supporting rod around the axis; and the limiting ring cooperates with the positioning ring groove.

[0023] In the embodiment of the present application, in order to ensure that the supporting rod does not move along its own axis during the installation of the wireless transceiver, a limiting ring and a positioning ring groove are provided to position the supporting rod.

[0024] As a possible implementation manner, the diameter of the orifice support plate is not less than twice the diameter of the blasthole.

[0025] In the embodiment of the present application, it is necessary to consider that if the supporting area of ​​the orifice supporting plate is too small, the orifice of the blast hole may be damaged during the installation process. Therefore, in order to avoid this situation, it is necessary to ensure that the diameter of the orifice supporting plate is at least twice the diameter of the blast hole.

[0026] The beneficial effects of the digital electronic detonator detonation control method provided in this embodiment are:

[0027] The digital electronic detonator detonation control method analyzes detonation parameter data to determine the placement and required number of digital electronic detonators. It then rationally groups the delayed detonation according to the detonation delay time data to ensure the effectiveness of the delayed detonation. This also allows wireless transceivers to be paired with multiple digital electronic detonators according to different groups, thereby improving the accuracy of delayed blasting while reducing equipment costs and achieving better blasting results. Furthermore, by fully considering the detonation parameter data and the material data of the digital electronic detonator installation location, the parameters for installing the wireless transceiver for blasthole blocking are determined. This effectively ensures that the wireless transceiver blocks the blasthole, preventing damage to the wireless transceiver caused by environmental influences when left outside the blasthole. It also facilitates the use of the wireless transceiver for blasthole blocking, achieving a better blockage and ensuring the effectiveness of the blasting. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0034] In recent years, the use of digital electronic detonators for blasting operations has become increasingly common, particularly in underground tunnels and other areas where manual blasting is unsuitable. Digital electronic detonator blasting utilizes a digital electronic detonator placed in the blasthole. A wireless transceiver connected to the digital electronic detonator establishes signal communication with the blasting control terminal, enabling delay adjustment and blasting command control for precise blasting operations.

[0035] Of course, most current digital electronic detonator blasting control systems utilize a one-to-one fixed-point control system, where one wireless transceiver corresponds to one digital electronic detonator. This approach often fails to efficiently achieve precise blasting control, increasing equipment costs and the workload of coordinating and adjusting delay control between different blasting points. Furthermore, since digital electronic detonators require pins to connect to wireless transceivers for signal control, and to ensure energy is not lost after the detonator explodes in the blasthole, the blasthole must be sealed after the detonator is buried. This can affect the wireless transceiver's reception of wireless signals. Therefore, the configuration of the wireless transceiver requires careful analysis and consideration.

[0036] refer to Figure 1The present invention provides a method for controlling the initiation of digital electronic detonators. This method analyzes initiation parameter data to determine the placement and required number of digital electronic detonators, and then rationally groups delayed initiation groups based on initiation delay time data to ensure effective delayed initiation. This also allows wireless transceiver 01 to be paired with multiple digital electronic detonators according to different groups, thereby improving the accuracy of delayed blasting while reducing equipment costs and achieving better blasting results. Furthermore, by fully considering the initiation parameter data and the material data of the digital electronic detonator installation location, the parameters for the wireless transceiver 01 to block the blasthole 02 are determined. This effectively ensures that the wireless transceiver 01 blocks the blasthole 02, preventing damage to the wireless transceiver 01 caused by environmental influences while remaining outside the blasthole 02. Furthermore, the wireless transceiver 01 can be used to block the blasthole 02, effectively ensuring that the wireless transceiver 01 blocks the blasthole 02. This prevents damage to the wireless transceiver 01 caused by environmental influences while being left outside the blasthole 02. Furthermore, the wireless transceiver 01 can be used to block the blasthole 02, effectively achieving effective blasting results.

[0037] The digital electronic detonator detonation control method includes the following main steps:

[0038] S1: Obtain initiation parameter data, perform initiation analysis, and determine the installation position and number of digital electronic detonators.

[0039] This step is to conduct blasting analysis based on the specific blasting situation, and ultimately determine the location and quantity of detonators to be installed, providing basic parameters for subsequent pairing and installation.

[0040] S2: According to the detonation parameter data, the detonation delay time data is obtained, and the digital electronic detonators are grouped according to the detonation delay time data to form delayed detonation grouping data.

[0041] To achieve a one-to-many reasonable pairing of the wireless transceiver device 01 and the digital electronic detonator, reasonable grouping can be performed based on the detonation delay time, and then a one-to-many reasonable pairing of the wireless transceiver device 01 and the digital electronic detonator can be completed within the group.

[0042] S3: According to the installation position of the digital electronic detonator and the delayed detonation group data, the blastholes 02 are opened in groups, and space for the installation of the wireless transceiver 01 is reserved.

[0043] In this embodiment, since the wireless transceiver 01 is required to be used as a structure for blocking the blasthole 02 , when the blasthole 02 is opened, it is necessary to reserve space for installation in combination with the structure of the wireless transceiver 01 .

[0044] S4: Obtain material data of the digital electronic detonator installation location, perform mechanical analysis in combination with the detonation parameter data, and install the wireless transceiver 01 using the detonator installation device 04 based on the analysis results.

[0045] This step is mainly to complete the installation of the wireless transceiver 01 according to the specific installation situation, including:

[0046] The explosion pressure value is obtained based on the detonation parameter data; the effective blocking and holding area is determined based on the pressure value and the ultimate stress condition of the wireless transceiver 01; the installation parameter data of the wireless transceiver 01 is determined based on the material data of the digital electronic detonator installation position and in combination with the effective blocking and holding area; based on the installation parameter data, the wireless transceiver 01 is installed using the detonator installation device 04.

[0047] The ultimate goal of wireless transceiver 01's blocking of blasthole 02 is to determine the maximum blocking force it can exert. This blocking force must be sufficient to withstand the shock pressure generated by the explosion of the digital electronic detonator during blasting. Therefore, during analysis, the shock pressure of the explosion must be determined based on the detonation parameter data. Furthermore, the effective contact area of ​​the material at blasthole 02 that the wireless transceiver 01 must utilize during blocking, combined with the structural strength of the wireless transceiver 01 and the material data at the blasthole 02, must be determined to prevent the wireless transceiver 01 from being pushed out of the blasthole 02 during the impact of the explosion. The effective contact area can be accurately calculated based on the impact pressure and the structural strength of the wireless transceiver 01. This allows the wireless transceiver 01's contact area within the blasthole 02 to be adjusted during installation, taking into account its installation method and structure, to ensure it is no less than the calculated theoretical effective contact area.

[0048] refer to Figure 2The wireless transceiver 01 includes a blocking shell 11, a blocking ball 12, a sealing filler 03, a signal receiving module 13, a signal processing module 14, a signal output module 15 and an output connection line 16; one end of the blocking shell 11 is sequentially provided with a blocking groove, a receiving groove 112 and a filling groove 111 that are interconnected, and a communication hole 114 is provided at the bottom of the filling groove 111; a loosening cavity 1131, a deformation cavity 1132 and a supporting cavity 1133 are sequentially formed in the blocking groove from the end close to the receiving groove 112 to the end away from the receiving groove 112; the diameters of the loosening cavity 1131, the deformation cavity 1132 and the supporting cavity 1133 decrease in sequence; the blocking ball 12 is located in the blocking groove, and the blocking ball The diameter of 12 is adapted to the diameter of the loosening cavity 1131; a guide column 121 is formed at one end of the blocking ball head body 12, and the guide column 121 is slidably set in the accommodating groove 112; the blocking ball head body 12 is respectively provided with an adjustment threaded hole and a device hole 122 that are interconnected along the axis of the guide column 121; the adjustment threaded hole is located at the end away from the guide column 121; the signal receiving module 13, the signal processing module 14 and the signal output module 15 are connected in sequence and are all set in the device hole 122; the sealing filler 03 is set in the filler groove 111; one end of the output connecting line 16 is connected to the signal output module 15, and the other end passes through the sealing filler 03 and is connected to the terminal 17 located at the end of the communication hole 114.

[0049] The installation and adjustment of the effective contact area of ​​wireless transceiver 01 is closely related to the structure of wireless transceiver 01. This solution provides a structure for wireless transceiver 01. In this structure, blocking shell 11 is the main body for adjusting the effective contact area. Since the diameter of the blocking groove at one end of blocking shell 11 is smaller than that of blocking ball 12, when blocking ball 12 is pulled toward the mouth of blasthole 02 using detonator installation device 04, it squeezes blocking shell 11, causing blocking shell 11 to press against the wall of blasthole 02, thereby allowing blocking shell 11 to embed into the wall of blasthole 02. At this point, the end of blocking shell 11 forms an effective contact surface with the material of the wall of blasthole 02. Of course, based on the calculated theoretical effective contact area, the movement distance of blocking ball 12 can be adjusted, thereby adjusting the area of ​​the effective contact surface to match the theoretically calculated value. The effective abutment area formed by the end of the plugging shell 11 is closely related to the movement distance of the plugging ball 12. After establishing the relationship between the two, the relationship between the movement distance of the plugging ball 12 and the threaded tightening torque required for movement using the threaded connection is further analyzed. In this way, precise installation control can be achieved by using the detonator installation device 04 in conjunction with the adjustment threaded hole on the plugging ball 12 based on the threaded torque value. Of course, it should be noted that although the blast hole 02 is effectively blocked using the wireless transceiver 01, since the detonator installation device 04 will be separated from the plugging ball 12 after installation, the signal receiving module 13 located in the equipment hole 122 can communicate with the controller unimpeded through the adjustment threaded hole, ensuring that the wireless transceiver 01 can receive the controller's signal in a timely manner. In addition, for the blocking ball head 12, an equipment hole 122 and an adjustment threaded hole are opened on the axis. Since they are both hole-shaped grooves, the internal force is more evenly dispersed, avoiding stress concentration and reducing the structural strength of the wireless transceiver 01, ensuring that its blocking function can be stably achieved during the installation and blasting process.

[0050] Multiple stop steps 113 are formed along the axis of the deformation cavity 1132. The stepped surface of the stop step 113 faces the abutting cavity 1133. In the direction from the loose cavity 1131 toward the abutting cavity 1133, the minimum diameter of the stop step 113 is between the minimum and maximum diameters of the next adjacent stop step 113. It is understood that the detonator installation device 04 first adjusts the threaded hole to pull the blocking ball 12, thereby allowing the wireless transceiver 01 to stably block the blast hole 02. When the installation conditions are met, the detonator installation device 04 needs to be removed. This means that the threads need to be rotated in the opposite direction to loosen the detonator installation device 04 from the threaded adjustment hole 123. This could cause the blocking ball 12 to move back. Therefore, to prevent the blocking ball 12 from moving back, a stop step 113 is provided on the deformation cavity 1132. The drop surface of the stop step 113 serves as an abutment surface for the blocking ball 12 to move back, effectively preventing the blocking ball 12 from moving back. Of course, considering that the movement of the blocking ball 12 causes the effective abutment area on the end of the blocking shell 11 to continuously change, the diameters of adjacent stop steps 113 need to continuously change. The minimum diameter of the stop step 113 is between the minimum and maximum diameters of the next adjacent stop step 113 to effectively ensure this continuous change. At the same time, it also prevents the blocking ball 12 from continuously abutting the blocking shell 11 and compressing it, thereby preventing damage to the threads in the threaded adjustment hole 123 from long-term stress.

[0051] A guide rail is protruding from the wall of the receiving groove 112 around its axis; a guide groove is formed on the guide post 121; and the guide groove and the guide rail are in sliding engagement. The primary movement of the plugging ball 12 is sliding; rotation about its own axis is most important to avoid. This would cause a change in the fit between the detonator mounting device 04 and the threaded adjustment hole 123, directly affecting the thread tightening torque, and thus failing to achieve the theoretical effective contact area, resulting in poor sealing. Therefore, providing a guide rail in the receiving groove 112 to limit the rotational movement of the plugging ball 12 about its own axis can further ensure effective installation and ensure that the wireless transceiver 01 effectively blocks the blasthole 02.

[0052] Furthermore, the length of the output cable 16 within the receiving groove 112 must be no less than the maximum distance the plugging ball 12 can move within the groove. As will be appreciated, since the movement of the plugging ball 12 increases the distance between the guide post 121 and the filling groove 111, it is necessary to ensure that the output cable 16 cannot be severed after the plugging ball 12 moves. This area requires a reserve length for the output cable 16, and the reserve length is sufficient to ensure that the plugging ball 12 will not be severed even when it reaches the farthest end of its sliding motion.

[0053] Of course, blocking shell 11 is located within blasthole 02; the depth of blocking shell 11 relative to the opening of blasthole 02 is determined by the detonation parameter data and the material data of the digital electronic detonator's installation location. It is understood that the wireless transceiver 01 must both wirelessly communicate with an external controller and ensure that blasthole 02 is sealed. The threaded adjustment hole 123 provided on blocking ball 12 connects device hole 122 to the outside world, ensuring effective communication between signal receiving module 13 and the controller. Thus, the only concern is that the wireless transceiver 01 stably blocks blasthole 02. Since the end of blocking shell 11 is a key location for generating an effective abutment surface, the effective abutment it receives comes from the material of the installation location in contact with it. If the wireless transceiver 01 is located too close to the opening of blasthole 02, the material will not provide sufficient abutment, potentially leading to collapse of the blasthole 02. To avoid this, the depth to which the wireless transceiver 01 should penetrate blasthole 02 must be determined in conjunction with the material data of the installation location and the detonation parameter data.

[0054] A detonator installation device 04 is also provided herein for facilitating the installation of the wireless transceiver 01 provided in this embodiment. The detonator installation device 04 comprises an orifice support plate 41, a support rod 42, and a driver. The orifice support plate 41 is provided with a through hole. One end of the support rod 42 is connected to the driver, and the other end passes through the through hole. A threaded connector is formed on the end of the support rod 42 near the wireless transceiver 01. The threaded connector cooperates with the adjustment threaded hole on the plugging ball 12 to connect the support rod 42 to the plugging ball 12. The orifice support plate 41 contacts the orifice of the blast hole 02, and a support boss 411 is formed on the end of the orifice support plate 41 near the blast hole 02. The support boss 411 is embedded in the blast hole 02 and abuts the plugging shell 11.

[0055] The main functions of the detonator installation device 04 are, on the one hand, to stabilize the aperture of the blasthole 02 to prevent damage to the aperture of the blasthole 02 during the installation of the wireless transceiver 01, and on the other hand, to pull the blocking ball 12 to effectively install the wireless transceiver 01. During the installation of the wireless transceiver 01, the aperture support plate 41 can ensure that the support rod 42 does not move along the axis. In this way, the blocking ball 12 can be moved along the axis through threaded engagement to achieve support installation. When the support rod 42 rotates to reach the set thread torque value, it is necessary to rotate the support rod 42 in the opposite direction. At this time, the aperture support plate 41 no longer supports the aperture surface of the blasthole 02. The support rod 42 moves along the axis during the loosening process, thereby loosening the support rod 42 and the blocking ball 12, thus completing the installation of the wireless transceiver 01. This installation method is simple and efficient.

[0056] A positioning ring groove 412 is formed on the wall of the through hole around its axis. A retaining ring 421 is provided on the supporting rod 42 around its axis. The retaining ring 421 cooperates with the positioning ring groove 412. To ensure that the supporting rod 42 does not move along its axis during installation of the wireless transceiver 01, the retaining ring 421 and the positioning ring groove 412 can be provided to position the supporting rod 42.

[0057] Of course, the diameter of the orifice support plate 41 is not less than twice the diameter of the blasthole 02. It should be considered that if the support area of ​​the orifice support plate 41 is too small, the orifice of the blasthole 02 may be damaged during installation. Therefore, in order to avoid this, it is necessary to ensure that the diameter of the orifice support plate 41 is at least twice the diameter of the blasthole 02.

[0058] S5: Pair and connect the wireless transceiver devices 01 in each group according to the delayed detonation group data.

[0059] After the installation is completed, you can pair and connect according to the divided groups.

[0060] S6: Obtain the paired data information for verification and confirmation, and perform delayed detonation according to the verification results.

[0061] This step is mainly to confirm that the digital electronic detonators paired with the wireless transceiver 01 are connected normally before delayed detonation.

[0062] In summary, the digital electronic detonator detonation control method provided in the embodiments of the present application has the following beneficial effects:

[0063] The digital electronic detonator detonation control method determines the placement and required number of digital electronic detonators by analyzing detonation parameter data. It also performs reasonable delayed detonation grouping based on the detonation delay time data to ensure the effectiveness of delayed detonation. This also allows wireless transceiver 01 to be paired with multiple digital electronic detonators according to different groups, thereby improving the accuracy of delayed blasting while reducing equipment costs and achieving better blasting results. Furthermore, by fully considering the detonation parameter data and the material data of the digital electronic detonator installation location, the parameters for wireless transceiver 01 to block the blasthole 02 are determined. This effectively ensures that wireless transceiver 01 blocks the blasthole 02, preventing damage to the wireless transceiver 01 caused by environmental influences when left outside the blasthole 02. Furthermore, wireless transceiver 01 is conveniently used to block the blasthole 02, achieving a better blockage and ensuring the effectiveness of the blasting.
