Description

Technical Field

[0001] Embodiments herein relate to systems and methods performed therein. In particular, embodiments herein relate to improving the ability to meet desired specifications. Background Art

[0002] In the field of mining, quarrying and construction engineering, the typical working sequence of rock blasting is to plan a hole pattern, drill holes in the rock according to the hole pattern, place explosives in the holes, and detonate the explosives. Then, the resulting broken rock (e.g., blasted stone) is transported away. Usually, the broken rock needs to be further crushed by crushing it to obtain the desired size. Crushing equipment can handle broken rocks within a set size range. It is useful for the broken rock to have a suitable size both in the case of direct use of the broken rock and in the case of further crushing it. This is to make planning easier, increase profitability, and meet the requirements of the final product. However, the problem is that the broken rock does not always have a suitable size.

[0003] Additionally, rock blasting also causes vibrations and may also move rocks. Similar to having a desired crushing result, it may be desirable to specify the occurrence of vibrations and flying rocks.

[0004] The present disclosure proposes a feasible solution for the improvement of the system for handling rock blasting in an efficient manner. Summary of the invention

[0005] It is an object of the embodiments herein to improve the ability to approach a desired target.

[0006] According to aspects of the embodiments herein, the object is achieved by a method performed by a system for determining one or more parameters to be used in drilling a subsequent hole in a rock to approach a target. A first hole is drilled in the rock. The system collects data related to the rock, the data collected from a drill during the drilling of the first hole in the rock. The system further determines at least one drilling parameter based on the collected rock data. Then, a second hole is drilled in the rock using the at least one drilling parameter to approach the target.

[0007] This method can start with a drilling plan and improve the plan by collecting data with a drill rig and then using this data to adjust the drilling parameters. Therefore, this method improves the ability to meet the desired specifications, that is, the ability to approach the desired target. This is because the data collected during the drilling of the first hole in the rock will be used to determine (e.g., adjust) drilling parameters such as hole size, hole depth and direction. The determined drilling parameters are then used to drill subsequent holes. Using a drill rig to collect data is also advantageous because it can be dangerous for a human to perform this action.

[0008] According to one embodiment, when the drill bit is pulled out after drilling the first hole in the rock, data related to the rock can be collected from the drilling rig. Since data can be collected when the drill bit is pulled out after drilling, the drill bit can be used as a detector and more data can be collected, which further improves the ability to approach the desired target.

[0009] According to one embodiment, additional data related to the rock may be collected from the detector, wherein the collected additional data may include information about one or more physical characteristics of shock wave propagation, chemical analysis and / or material flow from the borehole, and wherein determining at least one drilling parameter may be based on the collected additional data of the rock. This is advantageous because the detector enables the collection of additional data, which may be used to determine the drilling parameters and this further improves the ability to approach a desired target.

[0010] According to one embodiment, at least one ignition parameter may be determined based on the collected rock data. According to one embodiment, at least one charge parameter may be determined based on the collected rock data. When performing a blast to approach a target, at least one ignition parameter and / or at least one charge parameter may be used together with at least one drilling parameter. This is advantageous because in addition to the drilling parameters, further parameters may be determined. These parameters may be used to simulate the blast and thereby drilling a second hole in the rock to approach the target may be more accurate.

[0011] According to one embodiment, it may be determined whether the goal is achieved based on whether the result of the blasting satisfies one or more criteria, wherein the result of the blasting may be based on the determined first hole and the determined second hole, and wherein the criteria may be associated with the predicted blasting result. This is advantageous because the result of the blasting will be improved until the goal is achieved, which in turn further improves the ability to approach the desired goal.

[0012] According to one embodiment, when the result of the blasting does not meet one or more criteria, at least one drilling parameter can be adjusted until the one or more criteria are met, and when the result of the blasting meets the one or more criteria, the rock can be continued to be drilled by using the determined at least one drilling parameter. This is advantageous because the drilling parameters will be improved, and the drilling operation using the adjusted parameters can be continued until the target is achieved, which further improves the ability to approach the desired target.

[0013] According to one embodiment, when the result of blasting does not meet one or more criteria, at least one charging parameter and / or at least one ignition parameter may be adjusted until one or more criteria are met, and when the result of blasting meets one or more criteria, the rock may continue to be drilled by using at least one drilling parameter determined, and blasting may be performed with at least one charging parameter and / or at least one ignition parameter. This is advantageous because the drilling parameters will be improved, and the drilling operation using the adjusted parameters may be continued until the target is achieved, which in turn further improves the ability to approach the desired target.

[0014] According to one embodiment, the target may be related to one or more of: size and / or size distribution of one or more broken rocks, reduction of ground vibration, reduction of blasting motion, reduction of flyrock, and reduction of CO2 emissions. Thus, the target may be related to different characteristics, which makes the method more flexible and more accurate.

[0015] According to one embodiment, the collected rock data and targets can be used as input to a computational model, which can determine a set of parameters to be used when drilling the second hole. This will improve the simulation and produce more reliable results, which can then be used to correct the placement of subsequent holes.

[0016] According to one embodiment, at least one second drilling parameter may be determined based on the collected rock data, and a third hole may be drilled in the rock using the at least one second drilling parameter.The result of the blasting may be based on the determined first hole and the determined second hole.

[0017] According to another aspect of the embodiments herein, the object is achieved by providing a system for determining one or more parameters to be used in drilling a subsequent hole in a rock to approach a target. The system is configured to drill a first hole in the rock. The system is further configured to collect data related to the rock, which is collected from a drill during the drilling of the first hole in the rock. The system is further configured to determine at least one drilling parameter based on the collected rock data. The system is further configured to drill a second hole in the rock using the at least one drilling parameter to approach the target.

[0018] Additionally, provided herein is a drilling rig that includes a system for determining one or more parameters to be used in drilling a subsequent hole in rock to approach a target.

[0019] The embodiments herein are based on the recognition that a drill rig drilling a hole in rock can be used to collect data from drilling a first hole. This data can then be used to drill a second hole, where new data can also be collected, for example to correctly place subsequent holes to approach a desired target.

[0026] The invention is described in more detail below with reference to the accompanying drawings in which examples of embodiments are shown. The invention is not limited to the described examples of embodiments; it is defined by the appended patent claims. The same reference numerals in the drawings refer to the same elements throughout.

[0027] Figure 1a An overview schematic diagram of an embodiment of the present invention including a system 10 is illustrated. The system 10 includes and controls a drilling rig 20. The system 10 may be, for example, a drilling rig control system. The system 10 is configured to determine one or more parameters based on a first hole drilled. The determined one or more parameters will be used to drill a subsequent hole in the rock 30 to approach a target. The target is related to a subsequent blasting of the rock 30. The system 10 may be, for example, a control system that can be used to perform or partially perform the method herein. The system 10 may be, for example, located in a cloud 50. The collected data may be transmitted from the drilling rig 20 to the system 10 in the cloud 50, and then the system 10 may send updated data such as updated drilling parameters back to the drilling rig 20. The system 10 may also be placed on the drilling rig 20 and then perform calculations locally.

[0028] Now refer to Figure 1bAn example scenario of a method performed by a system 10 according to an embodiment herein is described. The system 10 may be, for example, a drilling rig control system. The method is used to determine one or more parameters that will be used to drill a subsequent hole in a rock 30 to approach a target. In order to improve the ability to meet the desired specifications (e.g., the blasted stone meets the desired specifications, or a certain degree of reduction in ground vibration, etc.), it may be necessary to improve the crushing simulation. In order to improve this, reliable data about the rock 30 needs to be collected. This collected data can then be used to improve the crushing simulation and produce more accurate results, which can then be used for the placement of subsequent holes and drilling subsequent holes in the rock 30 to approach the desired results, such as approaching the target. According to the example scenario, there is a desired result for a subsequent blasting, and data is collected by the drill rig 20 while drilling a first hole. Then, the collected data is used to determine one or more parameters for drilling a second hole. This is to achieve or at least approach the desired result after the blasting.

[0029] Action 101: Drill a first hole in rock 30. This is to enable the system 10 to collect data.

[0030] Action 102: When the first hole has been drilled in the rock 30, data related to the rock 30 may be collected. Thus, during the drilling of the first hole in the rock 30, data is collected from the drilling rig 20. The data related to the rock 30 may, for example, include one or more of the following: rock mass characteristics, the presence and / or amount of water, geological characteristics, joints, geological modeling, wall stability, hardness coefficients, joint plane spacing levels, and joint plane directions and / or angles. The data related to the rock 30 may further include the presence and / or amount of material flow, which is a return drilling flow and may also be referred to as a drilling cutting flow, a drilling flow, or a material return flow.

[0031] Action 103: The data collected about the rock 30 associated with the first hole is used to determine at least one drilling parameter. Then, when drilling a second hole in the rock 30, the drilling parameter will be used. The drilling parameter may, for example, include one or more of the following: drilling pattern, hole diameter, hole depth, hole deviation, inclination of the rock 30, subdrilling, and platform height. Other parameters such as charging parameters and ignition parameters may also be used. When used herein, charging parameters may include one or more of the following: the amount of explosive material, the type of explosive material, the explosion energy, the hole pattern design, the charging method, the charging design, and the charging length. The ignition parameters may, for example, include one or more of the following: detonator system, delay time, delay mode, number of clean faces and free faces. In addition to collecting data during drilling, it is also possible to collect additional data for simulation by collecting data of the rock 30 with a detector. The additional data collected may include information from the borehole about one or more physical properties of shock wave propagation, chemical analysis, and / or material flow. Then, at least one drilling parameter may also be based on the additional data collected of the rock 30. In some embodiments, the rock 30 data may be collected while the drill bit is pulled out of the hole. In such embodiments, it may correspond to a probe, that is, data may be collected by the drill rig 20 while the drill bit is on its way down, and on its way up, at least a portion of the drill bit may act as a probe.

[0032] Action 104: A second hole is then drilled in the rock 30 using at least one drilling parameter, and thereby approaching the target. The target may be related to one or more of the following: the size and / or size distribution of one or more broken rocks, a reduction in ground vibration, a reduction in blasting motion, a reduction in flyrock, and a reduction in carbon dioxide emissions. Since explosives emit carbon dioxide, reducing the amount of explosives may also reduce emissions. The first hole and the second hole may be at least part of a hole pattern. However, although the first hole and the second hole may follow each other directly, they do not necessarily have to follow each other directly. There may be an initial hole pattern based on an initial simulation, and the collected data may be used for an updated simulation, which in turn results in an updated hole pattern. The data is collected when drilling the first hole, which may produce a first set of drilling parameters and a second set of drilling parameters. Then, the first set of drilling parameters and the second set of drilling parameters may be used when drilling the second hole and the third hole, respectively. This may be extended to also apply to more than three holes, such as all the remaining holes in the hole pattern. Similarly, the data collected from the first hole and the second hole may be used to determine the parameters for drilling the third hole.

[0033] Now refer to Figure 2The flowchart depicted in describes method actions performed by system 10 for determining one or more parameters to be used to drill a subsequent hole in rock 30 to approach a target, wherein the target is associated with a subsequent blast of rock 30, according to embodiments herein. These actions do not necessarily have to be performed in the order set forth below, but may be performed in any suitable order. Actions performed in some embodiments are marked with dashed boxes.

[0034] Action 201: The system 10, such as the drilling rig 20, drills a first hole in the rock 30. This action is related to action 101 above.

[0035] Action 201a: The system 10 collects data related to the rock 30, which is collected from the drilling rig 20 during the drilling of the first hole in the rock 30. This action is related to action 102 above.

[0036] Action 201b : The system 10 may collect data related to the rock 30 , which is collected from the drilling rig 20 when the drill bit is pulled out after drilling a first hole in the rock 30 .

[0037] Action 201c: The system 10 can collect additional data related to the rock 30, the additional data being collected from the detector, wherein the collected additional data can include information from the borehole regarding one or more physical properties of shock wave propagation, chemical analysis, and / or material flow, and wherein determining at least one drilling parameter can be based on the collected additional data of the rock.

[0038] Action 202: The system 10 determines at least one drilling parameter based on the collected data of the rock 30. This action is related to action 103 above.

[0039] Action 203: The system 10 may determine at least one charging parameter based on the collected data of the rock 30, wherein the at least one charging parameter may be used when blasting to approach the target.

[0040] Action 204: The system 10 may determine at least one ignition parameter based on the collected data of the rock 30, the at least one ignition parameter may be used when blasting to approach the target.

[0041] Action 205: The system 10 drills a second hole in the rock 30 using at least one drilling parameter to approach the target. This action is related to action 104 above. The first hole and the second hole can be at least part of a hole pattern. The target can be related to one or more of: size and / or size distribution of one or more broken rocks (e.g., blasted rocks), reduction in ground vibration, reduction in blasting motion, reduction in flyrock, and reduction in carbon dioxide emissions. The collected rock 30 data and the target can be used as input to a computational model, and wherein the computational model can determine a set of parameters to be used when drilling the second hole.

[0042] Action 206: The system 10 may determine whether the goal is achieved based on whether the result of the blasting satisfies one or more criteria. The result of the blasting may be based on the determined first hole and the determined second hole. The criteria may be associated with the predicted blasting result.

[0043] According to some embodiments, when the result of the blasting does not meet one or more criteria, at least one drilling parameter may be adjusted until the one or more criteria are met. When the result of the blasting meets one or more criteria, the rock 30 may continue to be drilled using the determined at least one drilling parameter.

[0044] According to some other embodiments, when the result of blasting does not meet one or more criteria, at least one charging parameter and / or at least one ignition parameter may be adjusted until the one or more criteria are met. When the result of blasting meets one or more criteria, the rock 30 may continue to be drilled by using the determined at least one drilling parameter, and blasting may be performed using the at least one charging parameter and / or at least one ignition parameter.

[0045] Action 207: The system 10 may determine at least one second drilling parameter based on the collected rock data.

[0046] Action 208: The system 10 may drill a third hole in the rock using the at least one second drilling parameter.The result of the blasting may be based on the determined first hole and the determined second hole.

[0047] Embodiments herein such as those mentioned above will now be further described and illustrated. The following applies to any suitable embodiment described above and may be combined therewith. Embodiments herein relate to collecting data with a drill rig 20, performing simulations with the collected data, and, for example, correcting subsequent holes. The collected data may be used to improve simulations, for example, the results of the simulations, using, for example, a machine learning (ML) model and / or an artificial intelligence (AI) model.

[0048] By having a desired blasting effect, the size of the broken blasted rocks can be controlled by the system 10. The desired blasting effect can depend, for example, on the amount of explosive placed in the hole (also referred to as a drill hole). There are many parameters that may affect the resulting shape and size of the blasted rocks. If the holes are dense, the blasting effect is small, and the broken blasted rocks can be produced in uniform sizes, but many holes are required. If the holes are sparse, the rock 30 near the hole can be blasted into smaller sized rocks than the rock 30 far from the hole.

[0049] Different explosives may have different blast effects per volume of explosive. Therefore, the hole diameter needs to be set according to the explosive used and the desired blast effect. The characteristics of the rock 30 and the blast action in the hole will affect the hole distance. The hole position and thus the hole distance can be determined by the hole pattern.

[0050] In order to plan the hole pattern, it may be necessary to understand the characteristics of the rock 30 and a simulation of the crushing. By estimating the composition of the rock 30, how to place the holes, and the blasting effect, a simulation of the crushing can be performed. This can be repeated until the crushing simulation indicates that the blasted rock falls within the set specifications. This may be a sufficiently large proportion of the blasted rock is within an acceptable size range. Using, for example, an ML model and / or an AI model, the collected data can be used to improve the simulation, such as the results of the simulation.

[0051] How to blast rock can be affected by, for example, the rock composition, the presence of fractures and the characteristics of the fractures. This knowledge can affect the accuracy of the fragmentation simulation. However, before blasting the rock 30, it may be difficult to gather knowledge about the shape and size of the blasted stone.

[0052] As described above, a drill rig 20 drilling a hole in a rock 30 can be used for data collection. Signals from the control system of the drill rig 20 can provide real-time information about various subsystems of the drill rig, such as hydraulics, power, etc. to the system 10. These signals can also provide information about the rock 30 in which the drill rig 20 is drilling, either directly or after signal processing. The system 10 filters the data from the control system of the drill rig 20, which can produce detailed rock information. An example of such information is the resistance encountered by the drill bit during drilling. This information, together with other parameters, can describe the composition of the rock 30 on which the hole is being drilled. This combined with the knowledge of where the drill bit is located (for example, by knowing the location of the entry hole, the direction of the hole, and how deep it has been drilled) can make it possible for the system 10 to map the volume of the rock 30. Especially when collecting from several holes. From this, a reliable three-dimensional image of the rock 30 can be established. In addition to hardness, the presence of cracks can also be determined by the system 10. By detecting the crack pattern and rock hardness between several holes, intermediate volumes can be interpolated, and different crack planes can also be detected. An example of mapping the volume of rock 30 may be, for example: V = B x S x BH x N, where V is the volume, B is the load, S is the spacing, BH is the platform height, and N is the number of holes.

[0053] The collected data can then be used by the system 10 to improve the crushing simulation and produce more reliable results. These results can then be used to correct subsequent hole placement. By using the drill rig 20 to measure the actual composition of the rock 30, a more accurate crushing analysis can be performed by the system 10. This can be used to correct, for example, the hole pattern, hole location and / or explosive charge during ongoing work to achieve an improved method to ensure that the size of the stone after the blast meets the set specifications.

[0054] As more holes are being drilled, more information about the rock can be collected and hole patterns such as hole images, drill hole locations and / or blast planning can be further improved.

[0055] To further improve the accuracy of the fragmentation simulation, additional information about the rock 30 can be collected by the system 10, such as, for example: seismic measurements of how the waves generated during drilling propagate in the rock 30. These typically occur outside the drill hole. Seismic measurements of how the waves generated during blasting propagate in the rock 30. These typically occur at a distance from the blasting. Seismic measurements can be used to more accurately determine the position of the drill head of the drilling rig 20. This can be performed by sending a probe into the hole to perform measurements with it. These measurements can be, for example, about the composition of the rock 30 and the direction of the hole, etc. The system 10 can analyze the blasted rock to measure the actual fragment distribution. This can be done visually (for example, with a drone equipped with a camera or a static camera).

[0056] In addition to improving fragmentation, additional properties can be optimized. For example, the presence of blast flyrock can be minimized, better vibration predictions can be made, and / or changes in the stability of nearby rock after a blast can be predicted with greater accuracy.

[0057] The embodiments herein may relate to the type of drilling performed above ground (eg, in an open pit mine), but underground applications are also possible.

[0058] The calculations may also be performed in one or more different places. For example, locally on the drilling rig 20, on a separate unit adjacent to the drilling rig 20, on the overall control system of the mine, a central server, or a cloud server. These calculations may be performed in one place, or may be distributed across various computing units.

[0059] Typical rock parameters may include one or more of the following: geology, joints (spacing and orientation), rock mass characteristics, presence of water, geological modeling, wall stability, stiffness coefficient, joint plane spacing class, and joint plane orientation / angle.

[0060] Typical drilling parameters may include one or more of the following: hole diameter, drilling pattern, hole depth, underdrill, inclination, platform height, and hole deviation.

[0061] Typical blasting (eg, ignition) parameters may include one or more of the following: type of explosive, detonation energy, charging method, charge design, charge length, delay pattern, and amount of explosive.

Where appropriate, the system 10 may be configured to operate in accordance with any of the examples and embodiments employing the solutions as described herein.

[0063] Thus, the communication circuit C in the control system 10 includes devices configured to communicate using a suitable communication protocol, depending on the implementation. The data communication link between different parts of the system 10 (e.g., between the drilling rig 20 and the system 10 in the cloud 50 or locally at the drilling rig 20) can, for example, utilize one or more different types of wired links or wireless links, such as xDSL, 2G, 3G, 4G, 5G TCP / IP, Wi-Fi, Bluetooth, WiMax, WLL, PSTN, optical fiber, or a combination thereof. However, the solution is not limited to any particular type of message or protocol.
