Description

Technical Field

[0001] The present invention relates to a detonator support device according to one aspect of the present invention and a method for filling blast holes according to another aspect.

[0002] This invention mainly relates to the mining industry using detonator support devices and loading methods.

[0003] The present invention also relates to an industrially manufactured detonator support device configured to surround a detonator unit. Background Technology

[0004] In a blasting operation, at least one borehole is drilled into the rock, and an explosive compound is positioned within the borehole. The explosive compound in the borehole is detonated by a detonator unit arranged in a detonator support device, thereby causing rock fragmentation by blasting.

[0005] Due to the lateral orientation within the borehole, current detonator supports used in the mining industry can slide along the detonation rope and become secured in the borehole or at the borehole collar. Current detonator supports must be attached to the detonation rope before it is inserted into the borehole. These supports are complex to operate in mining and often contain redundant components, making them susceptible to failure and bulky.

[0006] An example of a detonator support is shown in WO2020039332A1, in which the detonator unit is positioned in a housing having a first sidewall and a second sidewall, the first sidewall and the second sidewall being hinged together along one longitudinal side and being openable via a snap-fit ​​coupling along opposite longitudinal sides.

[0007] Drilling is typically done vertically. However, drilling can have different orientations, such as roughly horizontal or inclined. Summary of the Invention

[0008] The object of the present invention is to provide a detonator support that is easy and safe to operate, and at the same time provides a reliable attachment of the detonator support to a rope component (e.g., a detonator rope).

[0009] The purpose of this invention is to provide a detonator support that facilitates time-saving drilling and loading.

[0010] The goal is for the operator to always position the detonator unit correctly within the detonator support device.

[0011] The purpose of this invention is to provide a lightweight detonator support device.

[0012] The purpose of this invention is to provide a compact detonator support device.

[0013] The purpose of this invention is to provide a detonator support device that can be used in a flexible blasting system configured to be filled into a borehole in a mine.

[0014] The purpose of this invention is to provide a detonator support device that can be used in various blasting loading applications and systems in boreholes.

[0015] The purpose of this invention is to provide a detonator support device that does not get stuck in the borehole or the borehole collar during loading.

[0016] This objective, or at least one of the objectives, has been achieved by a detonator support device configured to internally support an elongated detonator unit. The detonator support device has an upper end and a lower end, and includes a first elongated sidewall hinged to a second elongated sidewall via a hinge member. A latching member of the detonator support device is configured to secure the first elongated sidewall to the second elongated sidewall in a closed state. A first rope clamping surface of the first elongated sidewall is configured in the closed state to be positioned opposite a second rope clamping surface of the second elongated sidewall for engagement with at least one rope member.

[0017] Alternatively, the detonator support device has an elongated detonator unit compartment that corresponds to the size of the detonator unit.

[0018] In this way, the operator can only locate the detonator unit in one possible way, which increases safety in the mine.

[0019] Alternatively, the detonator unit may contain an explosive material (such as PETN) configured to be connected to a rope component and a detonator.

[0020] Alternatively, the rope component may include a shock tube or any type of flexible linear explosive or a wire with an explosive material core encased in an outer sheath.

[0021] Alternatively, the operator installs the detonator inside a detonator unit pre-filled with an explosive material, such as PETN.

[0022] In this way, the detonator unit can be operated simply and safely, because regulations do not allow any pre-installed detonators in the detonator unit.

[0023] Alternatively, the elongated detonator unit is configured to be clamped into the detonator unit compartment of the detonator support device.

[0024] Alternatively, the steps of preparing an elongated detonator unit include applying a second rope component to the elongated detonator unit.

[0025] Alternatively, the steps of preparing an elongated detonator unit include applying a detonator connected to a first rope member or a second rope member.

[0026] Alternatively, hook-shaped elements are arranged inside the first elongated wall element and / or the second elongated wall element at the upper and / or lower ends of the detonator support device to hold the first rope member and / or the second rope member to the first elongated wall element and / or the second elongated wall element.

[0027] Alternatively, the elongated detonator unit has a first end and a second end.

[0028] Alternatively, the first end is configured to receive the second rope member.

[0029] Alternatively, the cross-section of the elongated detonator unit, taken perpendicular to the extension of the elongated detonator unit, is asymmetrical.

[0030] Alternatively, the elongated detonator unit compartment is configured to receive elongated detonator units, wherein the compartment space has a matched asymmetrical cross-section.

[0031] Alternatively, the interior of the elongated detonator unit is filled with explosives, such as PETN-based explosives.

[0032] Alternatively, the amount of PETN-based explosive in the elongated detonator unit is 30 to 60 grams, preferably 40 to 50 grams of PETN.

[0033] In this way, the preparation time for the detonator support device can be very short. The assembly time for installation can be less than 10 seconds.

[0034] Alternatively, the first elongated sidewall includes an opening for providing direct contact between the detonator unit and the explosive charge material to be filled in the blast hole (the borehole in which the explosive charge material is inserted).

[0035] In this way, the explosive charge material will fill the detonator support device and come into contact with the detonator unit.

[0036] In this way, the operator does not need to add emulsion material or any additional emulsion cartridge to the detonator support device.

[0037] Alternatively, the detonator support device has a conical element inside that forms a focused charge, which is positioned collinearly with the elongated detonator unit at one end and configured to form a plasma jet for impacting the explosive charge material.

[0038] Alternatively, the connecting member is formed as a snap-fit ​​member having at least two snap-fit ​​members, one of which has a different size compared to the other snap-fit ​​member.

[0039] In this way, the connecting components can be easily opened with one hand due to the asymmetrical force of the snap-fit ​​components that hold the detonator support device in place.

[0040] Alternatively, the outermost snap-fit ​​member involves a smaller snap-fit ​​force compared to one or more other snap-fit ​​members.

[0041] In this way, the operator can wear gloves. This prevents his bare hands from being exposed to explosive materials. Furthermore, explosive materials contain oil, and the loading operation during drilling can be difficult to manage due to slippery tools and other factors.

[0042] Alternatively, the upper end includes an upper through hole through which a rope member is configured to pass, and / or the lower end includes a lower through hole through which a rope member is configured to pass.

[0043] Alternatively, the detonator support device has an extension that extends along the centerline.

[0044] Alternatively, the upper through-hole and / or lower through-hole have extensions oriented parallel to the centerline.

[0045] Alternatively, the hinged member has an extension oriented parallel to the centerline.

[0046] Alternatively, the first rope clamping surface has an extension oriented parallel to the centerline.

[0047] Alternatively, the second rope clamping surface has an extension oriented parallel to the centerline.

[0048] Alternatively, the first rope clamping surface and the second rope clamping surface form a first channel in the closed state.

[0049] Alternatively, the upper through-hole and / or lower through-hole are openly connected to the first channel and are collinear with the first channel.

[0050] In this way, the detonator support device eliminates the risk of vertical orientation of the detonator support device at the collar of the borehole or in any cavity of the borehole by specifying that the rope member passes through the upper and lower through holes (i.e., the rope member contacts the upper and lower ends of the detonator support device).

[0051] Alternatively, the exterior of the first elongated sidewall or the second elongated sidewall is formed with a recessed elongated recess extending along the extension of the first elongated sidewall or the second elongated sidewall.

[0052] This also allows for minimizing the required diameter of the borehole, as the filling hose can be enclosed in a recessed, elongated cavity.

[0053] Alternatively, the elongated detonator unit compartment is formed inside the second elongated sidewall.

[0054] Alternatively, a support member is formed inside the second elongated sidewall for supporting the detonator unit in the closed state.

[0055] Alternatively, the first rope clamping surface and the second rope clamping surface form a channel in the closed state, in which the rope member is held.

[0056] Alternatively, the outer wall surface of the elongated detonator unit installed in the elongated detonator unit compartment serves as the connecting wall of the channel for connecting rope components.

[0057] Alternatively, the detonator support device includes a retaining device having: a cavity-shaped receiving portion of the detonator support device configured to surround the lower end of the detonator support device; an intermediate portion having a hollow space configured to surround the filling hose nozzle; and a radially outwardly extending borehole plug portion configured to engage with a borehole.

[0058] This provides a plug component designed to be securely anchored in the borehole, while the detonator support device supporting the detonator unit can be reliably and effectively positioned in the borehole.

[0059] Alternatively, the detonator support device is configured to be releasably connected to the retaining device.

[0060] Alternatively, the upper end of the detonator support is tapered, having a tip that faces away from the upper part of the detonator support.

[0061] Alternatively, the lower end of the detonator support is tapered, having a tip that faces away from the lower part of the detonator support.

[0062] Alternatively, the detonator support receiving portion includes a circular wall with a cut-out slot configured to receive a rope member exiting the detonator support when the detonator support has been connected to the detonator support receiving portion of the retaining device.

[0063] Alternatively, the detonator support receiving portion is formed with an inwardly facing wall section having a protrusion configured to match the elongated recess of the first elongated sidewall.

[0064] Alternatively, the intermediate portion is formed by a circular wall having at least one orifice configured to allow explosive filling material to pass from the filling hose nozzle through the orifice to the borehole.

[0065] Alternatively, the radially outward-extending borehole plug portion includes flexible, outwardly projecting protrusions, each of which has an outermost cut end configured to engage with the borehole wall.

[0066] Alternatively, at least one of the flexible outwardly projecting protrusions includes a rope member engagement recess into which the rope member is introduced when the detonator support has been connected to the detonator support receiving portion of the retaining device.

[0067] Alternatively, the rope member engagement recess is formed in the radially oriented side portion of the at least one flexible outwardly projecting protrusion.

[0068] This is achieved by configuring the protruding portion of the inward-facing wall section of the detonator support receiving portion of the retaining device to be surrounded in at least a portion of the elongated recess, thereby preventing undesirable relative rotation between the detonator support and the retaining device.

[0069] In this way, the rope components from the detonator support and extending through the retaining device will not be subjected to unwanted stretching or other impacts.

[0070] Meanwhile, the recessed elongated recess is configured to surround a filling hose for filling the borehole with a detonator support device, rope components, and explosive compounds, which extends between the borehole wall and the detonator support device.

[0071] This objective, or at least one of the objectives, has been achieved by a blasting system configured to be loaded into a borehole. The system includes a first detonator support configured to internally support a first elongated detonator unit, the first detonator support having an upper end and a lower end, and including a first elongated sidewall hinged to a second elongated sidewall via a hinge member. A latching member of the first detonator support is configured to secure the first elongated sidewall to the second elongated sidewall in a closed state. A first rope clamping surface of the first elongated sidewall is configured in the closed state to be positioned opposite a second rope clamping surface of the second elongated sidewall for engagement with a first rope member. The blasting system further includes: a first retaining device configured to engage the borehole and carry the first detonator support; and a second detonator support engaged to the first rope member at a distance from the first detonator support.

[0072] Alternatively, the second rope member is connected to the first detonator unit of the first detonator support device and is configured to be clamped between the third rope clamping surface of the first elongated sidewall and the fourth rope clamping surface of the second elongated sidewall.

[0073] Alternatively, the third rope member is connected to the second detonator unit of the second detonator support device and is configured to be clamped between the fifth rope clamping surface of the first elongated sidewall of the second detonator support device and the sixth rope clamping surface of the second elongated sidewall.

[0074] Alternatively, the first rope component may include a detonation rope and / or a shock tube.

[0075] Alternatively, the second and / or third rope components may include a detonation rope and / or a shock tube.

[0076] Alternatively, the second detonator support device is configured to internally support a second elongated detonator unit. The second detonator support device has an upper end and a lower end, and includes a first elongated sidewall hinged to the second elongated sidewall via a hinge member. A latching member of the second detonator support device is configured to secure the first elongated sidewall of the second detonator support device to the second elongated sidewall in a closed state. A first rope clamping surface of the first elongated sidewall of the second detonator support device is configured to be positioned opposite a second rope clamping surface of the second elongated sidewall of the second detonator support device in the closed state for engagement with a first rope member.

[0077] Alternatively, the first retaining device has: an upper portion including a cavity-formed detonator support receiving portion configured to surround the lower end of the first detonator support; an intermediate portion having an abutment surface configured to engage with a filling hose nozzle; and a lower portion including a radially outwardly extending borehole plug portion configured to engage with a borehole.

[0078] Alternatively, the second retaining device has: an upper portion including a cavity-formed detonator support receiving portion configured to surround the lower end of the second detonator support; an intermediate portion having an abutment surface configured to engage with a filling hose nozzle; and a lower portion including a radially outwardly extending borehole plug portion configured to engage with a borehole.

[0079] Alternatively, the first retaining device constitutes a support claw configured to engage the drill hole and be secured to the upper end of the first rope member.

[0080] Alternatively, the first retaining device is configured to engage the borehole and carry the first detonator support device by means of the first rope member.

[0081] Alternatively, the first detonator support device, which engages with the first rope member, is carried at a distance from the first holding device.

[0082] Alternatively, a second detonator support device, which is engaged with the first rope member, is carried at a distance from the first support device.

[0083] Alternatively, the third detonator support, which is connected to the first rope member, is carried at a distance from the second support.

[0084] Alternatively, the second detonator support device and / or the third detonator support device have the same technical attributes as the first detonator support device.

[0085] This approach enables the development of a blasting system that operates efficiently and facilitates cost-effective mining.

[0086] In this way, each detonator support device can be clamped onto the first rope member successively and continuously, and is securely closed and well protected along the first rope member.

[0087] This objective, or at least one of the objectives, has been achieved by a method for preparing a first detonator support device to be loaded into a borehole, the first detonator support device being configured to internally support a first elongated detonator unit, the first detonator support device having an upper end and a lower end, and including a first elongated sidewall hinged to a second elongated sidewall via a hinge member, a latching member of the detonator support device being configured to secure the first elongated sidewall to the second elongated sidewall in a closed state, a first rope clamping surface of the first elongated sidewall being configured in the closed state to be positioned opposite a second rope clamping surface of the second elongated sidewall for engagement with at least one rope member, the method comprising the steps of: providing the first detonator support device; preparing the first elongated detonator unit; installing the first elongated detonator unit in the first detonator support device; positioning a rope member at the first rope clamping surface or the second rope clamping surface; and closing and latching the first detonator support device in the closed state.

[0088] Alternatively, the method includes the following additional steps: providing a second detonator support; preparing a second elongated detonator unit; installing the second elongated detonator unit in the second detonator support; positioning a rope member at a first rope clamping surface or a second rope clamping surface of the second detonator support; and closing and latching the detonator support in the closed state.

[0089] Alternatively, a first detonator support is configured to be coupled to a first retaining device having an upper portion, a middle portion, and a lower portion. The upper portion includes a cavity-formed detonator support receiving portion configured to surround a lower end of the first detonator support.

The method further includes the steps of: installing the prepared second detonator support to the detonator support receiving portion of the second retaining device; engaging the loading hose nozzle with the intermediate portion of the second retaining device; advancing the loading hose nozzle into the borehole; filling the borehole with an explosive compound; and returning the loading hose nozzle.

[0091] This objective, or at least one of the objectives, has been achieved by an automatic or semi-automatic explosive material loading vehicle.

[0092] This objective, or at least one of the objectives, has been achieved through data media and data media products.

[0109] In the following description, exemplary embodiments of the invention will be described with reference to the accompanying drawings, wherein some less important details may be omitted from the drawings for clarity and understanding of the invention.

[0110] Figure 1The illustration shows a detonator support 1 according to a first example. The detonator support 1 is configured to internally support an elongated detonator unit 3. The detonator support 1 has an upper end 5 and a lower end 7, and includes a first elongated sidewall 9 hinged to a second elongated sidewall 11 via a hinge 13. A latch 15 of the detonator support 1 is configured to secure the first elongated sidewall 9 to the second elongated sidewall 11 in a closed state. A first rope clamping surface 17 of the first elongated sidewall 9 is configured to be positioned opposite a second rope clamping surface 19 of the second elongated sidewall 11 in the closed state for engagement at the detonator rope 21, such as a detonating rope or shock tube.

[0111] Figure 2 A detonator support 1 according to a second example is shown. The detonator support 1 is configured to internally support an elongated detonator unit 3. A first rope clamping surface 17 is configured to be positioned opposite a second rope clamping surface 19 in the closed state of the detonator support 1 for engagement with two detonator ropes, such as detonating rope 21' and shock tube 21''.

[0112] Figure 3 The figure illustrates a detonator support 1 according to a third example. The detonator support 1 is configured to internally support an elongated detonator unit 3. The elongated detonator unit 3 has an extension parallel to the centerline CL of the detonator support 1.

[0113] The first rope clamping surface 17 is configured to be positioned opposite the second rope clamping surface 19 in the closed state of the detonator support 1 for engagement with the detonator rope (not shown). The first rope clamping surface 17, having a first imaginary axis 22', and the second rope clamping surface 19, having a second imaginary axis 22'', form a rope channel in the closed state, wherein the first imaginary axis 22' and the second imaginary axis 22'' coincide. The orientation of the first imaginary axis 22' and the second imaginary axis 22'' is parallel to the centerline CL of the detonator support 1. The detonator support 1 includes a first elongated sidewall 9, which is hingedly connected to the second elongated sidewall 11.

[0114] The detonator support 1 has a detonator unit compartment 23 inside, which corresponds in size to the detonator unit 3 configured to be installed in the detonator support 1. The detonator unit 3 includes an explosive material (not shown) configured to be connected to the detonator cord and a detonator (not shown), the explosive material being, for example, PETN.

[0115] The detonator rope may include a shock tube or any type of flexible linear explosive or any wire with an explosive material core encased in an outer sheath.

[0116] In this way, the detonator unit can be operated simply and safely, because regulations do not allow any pre-installed detonators in the detonator unit.

[0117] Alternatively, the detonator unit 3 is configured to be sandwiched within the detonator unit compartment 23.

[0118] Alternatively, the steps of preparing the detonator unit 3 may include applying the second rope component to the detonator unit 3.

[0119] Alternatively, the hook-shaped element 25 is arranged inside the first elongated wall element and / or the second elongated wall element at the upper and / or lower ends of the detonator support 1 to hold the first rope member and / or the second rope member to the first elongated wall element and / or the second elongated wall element.

[0120] Alternatively, the cross-section of the elongated detonator unit, taken perpendicular to the extension of the elongated detonator unit, is asymmetrical (see, for example, see...). Figure 4 Furthermore, the detonator unit compartment 23 is formed to receive the detonator unit 3, wherein the compartment space presents a matched asymmetrical cross-section.

[0121] In this way, the operator can only locate the detonator unit in one possible manner, which increases safety and efficiency in the mine.

[0122] Alternatively, the detonator unit 3 is internally prepared with explosives, such as PETN-based explosives.

[0123] Alternatively, the amount of PETN-based explosive in the elongated detonator unit is 30 to 60 grams, preferably 40 to 50 grams of PETN.

[0124] In this way, the time required to prepare the detonator support device can be very short. The assembly time for installation can be less than 10 seconds.

[0125] In addition, the detonator support may include a tapered element 88 located at the lower end, which is used to increase the likelihood of detonating the explosives around it.

[0126] Figure 4 The diagram illustrates a cross-section of a detonator support device according to a fourth example. The cross-section of the detonator unit 3, taken perpendicular to its extension, is asymmetrical, and the detonator unit compartment 23 is formed to receive the detonator unit 3, wherein the compartment space presents a matching asymmetrical cross-section. The detonator support member 1 includes a first elongated sidewall 9, which is hingedly connected to a second elongated sidewall 11.

[0127] Alternatively, the first rope clamping surface 17 of the first elongated sidewall 9 is configured to be positioned opposite the second rope clamping surface 19 of the second elongated sidewall 11 in the closed state of the detonator support 1. In the closed state, the second elongated sidewall 11 holds the detonator unit in a fixed position within the detonator support 1.

[0128] Alternatively, the first elongated sidewall 9 and / or the second elongated sidewall 11 include at least one opening 25 for providing direct contact between the detonator unit 3 and the explosive fill material to be filled in the borehole.

[0129] The exterior of the second elongated sidewall 11 has a recessed elongated recess 27 extending along the extension of the second elongated sidewall 11.

[0130] In this way, the required diameter of the borehole can be minimized because the loading hose (not shown) configured to insert the detonator support 1 into the borehole can be enclosed in the recessed elongated recess 27.

[0131] like Figures 5a to 5c As shown, the detonator support 1 is positioned in the borehole 31 and moves along the borehole 31. Figure 5a The detonator support 1 is shown to be securely clamped to the detonating cord 21. The loading hose 29 moves upward, thereby pushing the support claw (not shown) to the end of the borehole, which carries the detonating cord 21 and thus also the detonator support 1.

[0132] Recessed elongated recess (e.g., see...) Figure 4 The device is configured to surround a loading hose 29 for loading a detonator support 1 into the borehole 31, a detonating rope 21, and an explosive compound (not shown) for blasting the borehole 31. The loading hose 29 extends between the wall 32 of the borehole 31 and the detonator support 1. Figure 5b This shows that the loading hose 29 has moved the detonator support 1 upwards by a certain distance. At cross-section AA, the borehole 31 narrows N in a direction orthogonal to the borehole extension, but widens W in the transverse direction, and the loading hose 29 rotates R together with the detonator support 1 at the point where the geometry of the borehole cross-section changes, adapting to the actual geometry, such as... Figure 5c As shown in the figure.

[0133] Figure 6The diagram illustrates a detonator support 1 according to the sixth example. The snap-fit ​​connector 15' is formed by at least two snap-fit ​​members, one of which has a different dimension than the other. This allows the snap-fit ​​connector 15' to be easily opened with one hand due to the asymmetrical force securing the detonator support 1. The operator (not shown) can wear gloves on his bare hands without exposing them.

[0134] Figure 7 The diagram illustrates a detonator support 1 according to the seventh example. A first rope clamping surface 17' of a first elongated sidewall 9 and a second rope clamping surface 19' of a second elongated sidewall 11 form a first channel for holding the detonating rope 21' in the closed state of the detonator support 1. A shock tube 21'' is connected to the detonator unit 3 of the detonator support 1 and is configured to be clamped between a third rope clamping surface 17'' of the first elongated sidewall 9 and a fourth rope clamping surface 19'' of the second elongated sidewall 11.

[0135] The third rope 21''' is connected to the detonator support 1 and is configured to be clamped between the fifth rope clamping surface 17''' of the first elongated sidewall 9 of the detonator support 1 and the sixth rope clamping surface 19''' of the second elongated sidewall 11.

[0136] Figures 8a to 8b The diagram illustrates a cross-section of the detonator support 1 according to the eighth example. The detonator unit 3 has a rectangular cross-section. A first shock tube 21' is held between the side walls of the detonator support 1 adjacent to the hinge 13. A second shock tube 21'' is held between the side walls of the detonator support 1 adjacent to the latch 15 of the detonator support 1. Figure 8a The closed state of the detonator support 1 is shown, and Figure 8b The detonator support 1 is shown in the open position.

[0137] Figures 9a to 9b The diagram illustrates a retaining device 51, which is configured to engage the drilled hole 31 and carry the detonator support 1 according to the ninth example. Figure 9a As shown, the detonator support 1 includes a retaining device 51 having a cavity-shaped receiving portion 53 that surrounds the lower end 7 of the detonator support 1. An intermediate portion 55 has an abutment surface 57 configured to engage a loading hose nozzle (not shown) that is configured to insert the retaining device 51 into the borehole 31 and carry the detonator support 1. A radially outwardly extending borehole plug portion 59 is configured to engage the borehole 31.

[0138] Alternatively, the radially outward-extending borehole plug portion 59 preferably comprises an elastic material that allows the inclined and outward-extending wing or flap to deform elastically, thereby allowing the radially outward-extending borehole plug portion 59 to engage the wall of the borehole 31.

[0139] Figure 9b The detonator support 1, including the retaining device 51, is shown in cross-section. The detonator support receiving portion 53 of the retaining device 51 (see...) Figure 9a The lower end 7 of the detonator support 1 is surrounded by the detonator support receiving portion 53 of the retaining device 51. The retaining device 51 has an inwardly facing wall section 60, which has a protruding portion 62 configured to intersect with the elongated recess of the detonator support (see also, for example, reference numeral 27). Figure 4 The recessed elongated recess 27 extends along the extension of the elongated sidewall 9 of the detonator support 1. The protruding portion 62 of the inward-facing wall section 60 of the detonator support of the retaining device 51 is configured to be surrounded in the recessed elongated recess 27 to prevent unwanted relative rotation between the detonator support 1 and the retaining device 51.

[0140] Figures 10a to 10b Different examples of the blasting system 100 are shown, and an exemplary method for preparing detonator supports 1', 1'' to be filled into the borehole 31 is illustrated. Figure 10c The illustration depicts an exemplary blasting system 100 and a method for loading another third detonator support 1'''. Figure 10a The diagram shows a borehole plug or support claw 70 attached to the detonation cord 21'. The support claw 70 is driven toward the bottom of the borehole 31 by means of a loading hose 29. As the loading hose 29 pushes the support claw 70 toward the bottom of the borehole 31, once the support claw 70 has been pushed a distance in the borehole 31 along with the detonation cord 21', the operator (not shown) secures ("clamps") the first detonator support 1' to the detonation cord 21'.

[0141] The "clamping" function is achieved by configuring the first rope clamping surface of the first elongated sidewall to be positioned opposite the second rope clamping surface of the second elongated sidewall in the closed state for engagement with the detonating rope 21'. The shock tube 21'' has been connected to the first detonator unit (not shown) of the first detonator support 1' (also "clamped" onto the first detonator unit by the aforementioned function).

[0142] like Figure 10a As shown, the support claw 70 thus carries the detonation cord 21' and the first detonator support 1'. The second detonator support 1'', including the shock tube 21'' connected to the second detonator unit, is "clamped" onto the detonation cord 21' at a location outside the borehole 31.

[0143] This detonator support does not allow for misalignment of the detonator units, as each unit has its own predetermined position. The detonator support does not require any emulsion cartridge. Assembly time for installing the detonator support can be less than 10 seconds.

[0144] The detonator unit is placed in the detonator support. The detonator unit is pre-filled with an explosive material, such as PETN.

[0145] Next, the detonator unit is clamped into the detonator support, and the detonating cord 21' is placed and locked in the channel formed by the first cord clamping surface and the second cord clamping surface in the closed state.

[0146] The detonator support may have an upper "fixed positioning element" that guides the shock tube 21'' into the channel. Furthermore, the detonator support includes a tapered element at its lower end to increase the likelihood of explosive detonation around it. The tapered element forms a so-called focusing charge, which creates a plasma jet of the impact explosive. The detonator support includes multiple openings around it to increase direct contact between the detonator unit and the explosive in the borehole.

[0147] The length of the detonator support is 150 mm to 200 mm, preferably 180 mm to 190 mm. The diameter of the detonator support is 25 mm to 40 mm, preferably 30 mm to 40 mm.

[0148] The interior of the detonator support may include latching members of various sizes for securing the first and second elongated sidewalls to each other. In this way, an operator can manipulate the detonator support using only one hand, for example, by applying pressure to the middle of the detonator support to lock it in place.

[0149] exist Figure 10b An exemplary method utilizing a retaining device 51, which is coupled to and carries a detonator support 1, is illustrated. A loading hose 29 moves the retaining device 51 upward within the borehole 31. The retaining device 51 is configured to engage the borehole 31 and carry a first detonator support 1'. A second detonator support 1'' is clamped to an impact rope 21, which is coupled to the first detonator support 1'. After final positioning of the blasting system 100, an explosive compound is supplied to the loading hose 29 to fill the borehole 31.

[0150] exist Figure 10c The diagram shows a blasting system 100 configured to be filled into a borehole 31. The system 100 includes a first detonator support 1' configured to internally support a first elongated detonator unit (not shown).

[0151] The first detonator support 1' has an upper end and a lower end, and includes a first elongated sidewall hinged to the second elongated sidewall via a hinge member (not shown). A latching member (not shown) of the first detonator support 1' is configured to secure the first elongated sidewall to the second elongated sidewall in a closed state. A first rope clamping surface (not shown) of the first elongated sidewall is configured in the closed state to be positioned opposite a second rope clamping surface (not shown) of the second elongated sidewall for engagement with the first rope member 21'.

[0152] The blasting system 100 also includes a first retaining device 51' configured to engage the borehole 31 and carry the first detonator support 1'. The first retaining device 51' has: an upper portion including a cavity-formed detonator support receiving portion (not shown) configured to surround the lower end of the first detonator support; an intermediate portion having an abutment surface configured to engage with a filling hose nozzle (not shown); and a lower portion including a radially outwardly extending borehole plug portion 59' configured to engage with the borehole. The filling hose is used to push the first detonator support 1' upward.

[0153] The second detonator support 1'' engages with the first rope member 21' at a distance from the first detonator support 1'. The second detonator support 1'' is configured to internally support a second elongated detonator unit (not shown). The second detonator support 1'' has an upper end and a lower end, and includes a first elongated sidewall hinged to the second elongated sidewall via a hinge member. A latching member of the second detonator support is configured to secure the first elongated sidewall to the second elongated sidewall of the second detonator support in a closed state, and a first rope clamping surface of the first elongated sidewall of the second detonator support is configured to be positioned opposite to a second rope clamping surface of the second elongated sidewall of the second detonator support in the closed state for engagement with the first rope member 21'.

[0154] The second retaining device 51'' connected to the third detonator support 1''' has: an upper portion including a cavity-formed detonator support receiving portion configured to surround the lower end of the second detonator support; an intermediate portion having an abutment surface configured to engage with a filling hose nozzle; and a lower portion including a radially outwardly extending borehole plug portion 59'' configured to engage with a borehole.

[0155] After the corresponding first detonator support 1' and third detonator support 1''' are positioned by means of a loading hose, a portion of the borehole 31 associated with the corresponding detonator support is filled with an explosive compound.

[0156] A hole is formed in the middle portion of the wall of the first retaining device 51', so that the pumped explosive compound is forced upward in the borehole to fill the portion of the borehole 31 associated with the first detonator support 1'.

The method is initiated in step 121. Step 122 includes providing a second detonator support. Step 123 includes preparing a second elongated detonator unit.

Step 130 includes filling the borehole with an explosive compound. Step 131 includes retracting the loading hose nozzle. Step 132 includes stopping the method.
