[0028] The following will describe the embodiments of the present application in detail with reference to the drawings.
[0029] It should be clear that the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.
[0030] At present, during the process of lowering the slotted fracturer into the preset position in the blast hole in the open-pit mine, it is impossible to accurately control the slotted orientation position of the slotted fracturer, which may cause the carbon dioxide pre-splitting blasting not to form a complete through crack, resulting in a certain degree of energy loss of the energy-discharging gas in the rock mass. To solve the above problems, on the one hand, as Figure 1 shown, an embodiment of the present application provides a slotted fracturer assembly, which may include a slotted fracturer 1, a mark 3, a suspension rope 5, and a ranging illuminator 8.
[0031] The slotted fracturer 1 has a tubular structure, and a slot 2 is axially formed on the tube wall of the tubular structure; the slotted fracturer 1 can guide the blasting energy in the slotted fracturer 1 by using the slot 2 on the tube wall to accurately control the blasting effect. The slot 2 can be formed on the tube wall of the tubular structure along a set direction. In this embodiment, the set direction of the slot 2 is along the axial direction of the tubular structure, that is, the slot 2 extends along a direction parallel to the axial direction of the tubular structure, and the slot 2 can have a set length, a set shape, a set position, or a set depth, etc. The slot 2 can communicate with the inner cavity of the tubular structure. Specifically, the set direction of the slot 2 can be set according to the blasting requirements, so that the slot 2 can form a guiding effect on the blasting energy and form directional cracks around the blast hole along the direction of the slot 2. For example, in this embodiment, the set direction of the slot 2 is parallel to the axial direction of the tubular structure. The number of the slots 2 can be one or more than two. Similarly, the set length of the slot 2, the number of the slots 2, and the distribution positions of the multiple slots 2 on the tube wall of the tubular structure can also be set according to specific blasting requirements.
[0032] The slotted fracturer 1 can be a slotted fracturer 1 widely used in current engineering applications. For example, the fracturing substance installed in the slotted fracturer 1 can be explosive or carbon dioxide, etc. At this time, the slotted fracturer 1 is a carbon dioxide slotted fracturer. The carbon dioxide phase change fracturing technology, as a rock-breaking method without chemical explosives, has higher controllability and environmental compatibility compared with traditional explosive blasting, and has less impact on the vibration, flying stones, pollution, and noise of the surrounding environment.
[0033] The mark 3 is used to be arranged at the first end of the slotted fracturer 1; the mark 3 is used to indicate the angular position of the slotted fracturer 1 when the slotted fracturer 1 is lowered into the blast hole, so as to orient the slot 2 of the slotted fracturer 1 towards the preset direction, so that the slot 2 can form a guiding effect on the blasting energy and realize precise blasting of the rock mass. The mark 3 can be made of easily recognizable materials such as reflective substances or self-luminous substances, so that it can be recognized by construction personnel in the relatively dark environment in the blast hole. As Figure 2As shown, the mark 3 can be installed on the first end of the slit-fracture device 1 by means of adhesion or fastener connection. The first end of the slit-fracture device 1 is the end facing the orifice of the blast hole, that is, the end facing the construction personnel, so that the construction personnel can observe and identify it. The second end of the slit-fracture device 1 is the end away from the orifice of the blast hole.
[0034] The lifting rope 5 is used to connect the slit splitter 1 so as to lift the slit splitter 1 into the blast hole; the lifting rope 5 can be made of soft materials, such as nylon rope, steel wire rope, etc., so that it has high adjustment flexibility in the narrow space of the blast hole. The lifting rope 5 can not only be used to lift the slit splitter 1 into the blast hole, but also can be used to rotate the slit splitter 1 so that the slit 2 of the slit splitter 1 faces a preset direction. The lifting rope 5 can be connected to the first end of the slit splitter 1, for example, a hook can be set on the slit splitter 1, or a structure such as a ring can be set to facilitate the hanging and connection of the lifting rope 5.
[0035] The distance-measuring illuminator 8 is used to measure the distance of the slit-fracture device 1, and the distance-measuring illuminator 8 can provide lighting. It can be understood that the lighting function of the distance-measuring illuminator 8 facilitates the observation of the indicated direction of the mark 3, thereby facilitating the adjustment of the angle position of the slit-fracture device 1, especially when the mark 3 is made of a reflective material, the illumination light emitted by the distance-measuring illuminator 8 is reflected by the mark 3, making it easier to identify the mark 3. The distance-measuring function of the distance-measuring illuminator 8 facilitates the monitoring of the actual position distance of the slit-fracture device 1 when the slit-fracture device 1 is lowered to the preset position of the blasthole, thereby accurately controlling the installation position of the slit-fracture device 1 and improving the blasting accuracy.
[0036] The slit splitter assembly provided in the embodiment of the present application includes a slit splitter 1, a mark 3, a hanging rope 5, and a distance-finding illuminator 8; the slit splitter 1 has a tubular structure, and a slit 2 is opened on the wall of the tubular structure along the axial direction; the mark 3 is used to be set at the first end of the slit splitter 1; the hanging rope 5 is used to connect the slit splitter 1 to hang the slit splitter 1 into the blast hole; the distance-finding illuminator 8 is used to measure the distance of the slit splitter 1, and the distance-finding illuminator 8 can provide lighting. The slit splitter assembly can effectively improve the positioning accuracy of the slit splitter 1 during construction and installation.
[0037] Optionally, in an embodiment of the present application, the slotted fracturer assembly further includes a lifting ring 4 for connecting a lifting rope 5; at least two screw holes are symmetrically arranged around the axis at the first end of the slotted fracturer 1 for installing the lifting ring 4. For example, two screw holes can be symmetrically arranged around the axis at the first end of the slotted fracturer 1 for installing the lifting ring 4. The lifting ring 4 has a screw rod structure and a ring structure. The screw rod structure is provided with an external thread adapted to the internal thread of the screw hole. The thread engagement length and the thread diameter specification of the two can be adaptively designed according to the force condition; the ring structure of the lifting ring 4 is used for threading the lifting rope 5. It can be understood that two screw holes are symmetrically arranged to install the lifting ring 4 respectively. After the lifting rope 5 passes through the lifting ring 4, it is convenient to form a rotational torque to adjust the angular position of the slotted fracturer 1.
[0038] Optionally, in an embodiment of the present application, the vertical plane along the length direction of the mark 3 and the vertical plane along the length direction of the slit 2 have a preset angle. The preset angle can be any angle. For example, for the convenience of construction workers to observe and judge, the preset angle can be 0 degrees or 180 degrees, that is, the length direction of the mark 3 is consistent with or flush with the length direction of the slit 2. In this way, when the construction worker lowers the slotted fracturer 1 into the blast hole, observing the orientation of the mark 3 is equivalent to observing the orientation of the slit 2, thereby improving the usability of the assembly and being beneficial to improving the construction efficiency.
[0039] Optionally, in an embodiment of the present application, the mark 3 is provided with a reflective layer for reflecting the illumination light of the distance measuring illuminator 8, and the length of the reflective layer is greater than the width of the reflective layer. It can be understood that the length of the reflective layer is greater than the width of the reflective layer, which is convenient for forming the indicating effect of the mark 3. For example, the reflective layer can be a rectangle, an arrow shape or other directional shapes. The mark 3 can specifically adopt a reflective sticker, etc. The material model selected for the reflective sticker should be adhesively bonded to the metal material of the slotted fracturer 1, and the retroreflective coefficient of the reflective intensity should be greater than 140 cd / lx / m².
[0040] Optionally, in an embodiment of the present application, the mark 3 is provided with a self-luminous element, and the length of the light-emitting part of the self-luminous element is greater than the width of the light-emitting part of the self-luminous element. The mark 3 adopting the self-luminous element can further improve the applicability of the assembly. For example, in an environment where it is not convenient to arrange strong light illumination, or when the illumination device 6 of the distance measuring illuminator 8 fails, the self-luminous element of the mark 3 can ensure that the construction can continue. The self-luminous element of the mark 3 can specifically adopt a light-emitting lamp or a fluorescent part, etc.
[0041] To ensure the normal progress of the construction process and avoid safety accidents, optionally, in an embodiment of the present application, the length of the lifting rope 5 is not less than the shortest length l, where ; H is the depth of the blast hole, h is the length of the slotted fracturer 1, and N is the length required for the construction worker to operate the lifting rope 5, which is usually selected as 4 m; and / or,
[0042] The diameter of the lifting rope 5 is not less than the minimum diameter d, where, ; T is the tension force on the lifting rope 5 when lowering the slotted fracturer 1, D is the linear density of the lifting rope 5, R is the tensile strength of the lifting rope 5, and π is the pi.
[0043] Optionally, in an embodiment of the present application, the slotted fracturer 1 includes a filling head, a sealing gasket, an initiating agent, and a tube body; the filling head is provided with an inflation port, and terminal posts are provided at both ends of the filling head; a slit 2 is formed on the tube wall of the tube body, and the filling head is detachably connected to one end of the tube body; the initiating agent is arranged inside the tube body, and a terminal post is provided at one end of the initiating agent, and the terminal post of the initiating agent is connected to the terminal post of the filling head close to the tube body; the sealing gasket is arranged between the filling head and the tube body. The slotted fracturer 1 can be specifically a disposable carbon dioxide slotted fracturer. When assembling the slotted fracturer 1, connect the terminal post inside the filling head to the terminal post of the initiating agent. Additionally, place the sealing gasket at the threaded port of the tube body of the slotted fracturer 1, pass the initiating agent through the sealing gasket and tighten the filling head to complete the sealing operation of the filling head, the initiating agent, and the tube body; the disposable slotted 2 fracturing tube can be inflated through a carbon dioxide filling device.
[0044] Optionally, in an embodiment of the present application, the outer diameter of the tube body is greater than the outer diameter of the filling head. At least two screw holes are symmetrically arranged around the axis at the end of the tube body where it is connected to the filling head. The screw holes are used to install the lifting rings 4, where the inner diameter of the screw holes is less than half of the difference between the outer diameter of the tube body and the outer diameter of the filling head. Specifically, the outer diameter of the ring-shaped structure at the upper part of the lifting ring 4 should not be greater than 5 cm; the inner diameter of the ring-shaped structure of the lifting ring 4 should be greater than the outer diameter of the lifting rope 5. The inner diameter of the screw holes is less than half of the difference between the outer diameter of the tube body and the outer diameter of the filling head, so as to ensure that the screw holes are easy to process and have good stress performance.
[0045] Optionally, in an embodiment of the present application, the distance measuring and lighting instrument 8 includes a lighting device 6 and an infrared laser distance measuring device 7 arranged in parallel, and the lighting device 6 and the infrared laser distance measuring device 7 are respectively provided with independent switches. The lighting intensity of the lighting device 6 should be greater than 2000 lumens to provide sufficient lighting; both the lighting device 6 and the infrared laser distance measuring device 7 are arranged at the front end of the distance measuring and lighting instrument 8 and the distance between them is less than 5 cm, which is convenient for use in engineering scenarios with blast holes within 100 mm. The maximum distance range measured by the infrared laser distance measuring device 7 should be greater than 25 meters, and the ranging error is within the range of ±0.1 m; the infrared laser distance measuring device 7 is equipped with a distance display screen. In addition, the distance measuring and lighting instrument 8 can adopt a design with a replaceable mobile power source.
[0046] Second aspect, asFigure 3 As shown, an embodiment of the present application provides a positioning method using any of the slotted fracturing device assemblies, and the positioning method includes:
[0047] S1. Assemble the slotted fracturing device 1.
[0048] Specifically, according to the usage requirements, each component of the slotted fracturing device 1, such as a disposable carbon dioxide slotted fracturing device, can be assembled. For example, connect the inner terminal of the filling head to the terminal of the initiation agent. Additionally, place a gasket at the threaded port of the tube body of the slotted fracturing device 1, pass the initiation agent through the gasket and tighten the filling head to complete the sealed installation of the filling head, the initiation agent, and the tube body. Then, the overall resistance between the filling head and the initiation agent can be detected through the two terminals on the outer side of the filling head to confirm whether there is a conductive path.
[0049] S2. Set the identifier 3 at the first end of the slotted fracturing device 1.
[0050] The identifier 3 can be a reflective sticker, which is cut into a rectangular strip with a width of 2 cm and a length of 20 cm. Based on the assembled slotted fracturing device 1, the reflective sticker is pasted radially outward from the center of the end of the filling head, and the pasting direction can be along the set direction of the slot 2 of the slotted fracturing device 1.
[0051] After setting the identifier 3 at the first end of the slotted fracturing device 1, if the slotted fracturing device 1 is provided with screw holes for connecting the lifting rings 4, the lifting rings 4 can be further installed in the screw holes. For example, install the lifting rings 4 in the two screw holes of the slotted fracturing device 1 respectively, and ensure that the ring surfaces of the ring structures of the two lifting rings 4 are perpendicular to the end face of the filling head to ensure that the angular position of the slotted fracturing device 1 in the blast hole can be effectively rotated and adjusted during construction operations.
[0052] S3. Inject the fracturing substance into the slotted fracturing device 1.
[0053] For the slotted fracturing device 1, such as a disposable carbon dioxide slotted fracturing device, the disposable slotted fracturing tube can be inflated through a carbon dioxide filling device to inject the fracturing substance. The disposable carbon dioxide slotted fracturing device has been widely used in the industry, and will not be described in detail in this application. After the filling process is completed, the overall resistance of the fracturing tube system should be detected through the external circuit of the slotted fracturing device 1, and after confirming the conductive path, a short-circuit operation should be performed on the circuit to ensure the safety during transportation.
[0054] S4. Connect the lifting rope 5 to the slotted fracturing device 1.
[0055] After transporting the slotted fracturer 1 in the to-be-exploded state, such as a disposable carbon dioxide slotted fracturer, to the blasting site, connect the detonating wire with an appropriate hole length to the external terminal posts of the filling head, and select a sling 5 with an appropriate length. Pass one end of the sling 5 through the two lifting rings 4 in sequence so that the sling 5 is connected to the disposable carbon dioxide slotted fracturer. At this time, it should still be ensured that the ring surfaces of the ring-shaped structures of the two lifting rings 4 are perpendicular to the end face of the filling head. Subsequently, lower the disposable carbon dioxide slotted fracturer into the blast hole through the sling 5.
[0056] S5. Lower the slotted fracturer 1 into the blast hole, use the ranging illuminator 8 for illumination, and according to the direction indicated by the identifier 3, rotate and adjust the slotted fracturer 1 to the preset direction; and use the ranging illuminator 8 for ranging, and lower the slotted fracturer 1 to the preset position in the blast hole.
[0057] During the process of lowering the slotted fracturer 1, the illumination device 6 of the ranging illuminator 8 can be turned on to search the blast hole, find the position and direction of the identifier 3, that is, the reflective sticker, and direct the construction personnel and construction equipment according to the direction indicated by the reflective sticker. By adjusting the position of the sling 5 outside the blast hole, the purpose of rotating the angular position of the slotted fracturer 1 can be achieved, and finally the direction indicated by the reflective sticker, that is, the slot 2 of the slotted fracturer 1, faces the preset direction.
[0058] After adjusting the direction of the slot 2, start the infrared laser ranging device 7 of the ranging illuminator 8. The infrared laser ranging device 7 uses the high-precision measurement ability of infrared laser to determine the accurate position of the slotted fracturer 1 in the blast hole. This process needs to be continuously carried out until the slotted fracturer 1 is completely lowered to the preset position in the blast hole. When the slotted fracturer 1 reaches the preset position in the blast hole, it can be considered that all the construction operations for positioning the slotted fracturer 1 in the blast hole have been completed. At this time, the pre-blasting process of the slotted fracturer 1 is ready, and the next fracturing operation can be carried out.
[0059] Then, the blasting network can be assembled and its functions can be tested to ensure that the preparation work is ready. Conduct blasting warning and detonate the slotted fracturer 1. To improve the blasting effect, it is necessary to ensure that the operations of the slots 2 of each slotted fracturer 1 are consistent. This precise control is crucial for achieving effective rock fracturing and environmental safety.
[0060] The slotted fracturer assembly used in the positioning method provided by the embodiment of the present application includes a slotted fracturer 1, an identifier 3, a sling 5, and a ranging illuminator 8; the slotted fracturer 1 has a tubular structure, and a slot 2 is axially formed on the tube wall of the tubular structure; the identifier 3 is used to be arranged at the first end of the slotted fracturer 1; the sling 5 is used to connect the slotted fracturer 1 to lower the slotted fracturer 1 into the blast hole; the ranging illuminator 8 is used to range the slotted fracturer 1, and the ranging illuminator 8 can provide illumination. This positioning method can effectively improve the positioning accuracy of the slotted fracturer 1 during construction and installation.
[0061] This positioning method accurately controls the direction of the slit 2 of the slit fracturing device 1, so that the discharge pressure direction of the slit fracturing device remains consistent. In the application scenario of boundary pre-splitting, a well-shaped through pre-crack can be formed between the blasting area and the reserved area, ensuring the formation of a smooth slope surface with better integrity, weakening the damage of the main blast hole blasting to the reserved rock mass, and effectively guaranteeing the stability of the slope and the safe mining of the mine. In addition, the slit fracturing device assembly is convenient for measuring the depth and position of the slit fracturing device 1 in the blast hole, ensuring that the on-site construction implementation is consistent with the blasting design, achieving the design concept of precise blasting, completing the expected blasting effect, and helping to improve the rock-breaking ability of the slit fracturing device 1, especially the disposable carbon dioxide slit fracturing device, in open-pit mines and multiple application scenarios.
