Description

Technical Field

[0001] The present application relates to the field of basalt mining, and in particular to a basalt mining device and a method of use. Background Art

[0002] Basalt is a black or dark gray volcanic rock, which is mainly composed of silicates and ferromagnesian minerals. The structure of basalt is very tight, so it has extremely high density and hardness, which makes basalt widely used in the fields of construction and road construction. In ancient times, people have begun to use basalt to build city walls and palaces. In modern times, it is widely used in infrastructure construction such as roads, railways, highways, docks, etc. It is also an important material for building foundations in the construction industry. With the acceleration of urbanization and the improvement of people's requirements for the quality of building materials, the demand for basalt is increasing, and the amount of basalt mined is increasing year by year.

[0003] The most commonly used method for mining basalt is the drilling and blasting method, also known as the blasting method. This method achieves the purpose of mining by drilling holes in the rock mass and setting explosive packs for blasting. The drilling and blasting method has the advantage of high operating efficiency, especially when dealing with large pieces of basalt with high hardness. However, it has some disadvantages, which will produce noise, vibration and dust pollution, have a certain impact on the surrounding environment, and have great safety hazards. In addition to the drilling and blasting method, there are other methods for mining basalt, such as the splitting method, which is also a method for basalt mining. This method uses tools such as splitting rods to generate stress in the rock through manual operation, so that the rock splits in a predetermined direction. Compared with traditional blasting methods, the splitting method has the advantages of reducing mining costs, no noise, low dust pollution, and avoiding safety risks. However, for basalt, a rock with high hardness, the effect of the splitting method is not very ideal, mainly because the hardness of basalt is large, and the force required for splitting is also correspondingly large. In addition, the rock quality of basalt is relatively uniform and it is not easy to produce stress concentration, which will also affect the splitting effect, and its effect is not as good as the drilling and blasting method. With the continuous advancement of science and technology and increasingly stringent environmental protection requirements, it would be a major technological breakthrough if a new type of equipment could be developed that could significantly reduce or eliminate these negative impacts while maintaining the efficient mining of drilling and blasting, so as to achieve a more efficient, environmentally friendly and safe production method in the future rock mining field. Summary of the invention

[0004] The invention provides a basalt mining device and a use method, which are used to solve the problems of low mining efficiency, unsatisfactory mining effect, high energy consumption and serious equipment wear in the existing splitting mining of basalt with relatively high hardness.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A basalt mining device includes an impact module and a splitting module placed inside a borehole;

[0007] The impact module includes an impact piece and an impact power device for driving the impact piece to impact the inner wall of the drill hole. The impact power device can drive the impact piece to impact the inner wall of the drill hole. The impact force forms a stress wave inside the rock, so that stress changes occur inside the rock, changing the original structure of the rock.

[0008] The splitting module includes a widening piece and a hydraulic power drive device that drives the widening piece to expand the borehole. The widening piece applies a splitting force to the rock from inside the borehole to open the cracks in the rock. The impact power device and the hydraulic power drive device are in operation, and through the combined action of the impact force and the splitting force, a complex stress distribution is generated in the rock, causing the rock to crack and break internally, thereby improving the crushing efficiency.

[0009] In the basalt mining device of the present invention, an impact module and a splitting module are simultaneously arranged in the basalt borehole to crush the rock. The impact module can cause multiple damages inside the rock by generating stress waves, thereby effectively reducing the overall strength of the basalt. The splitting device further expands the borehole and utilizes the characteristic that the tensile strength of the rock is much lower than the compressive strength, so that the high-hardness basalt rock is easier to be crushed. This combined use method can combine the effects of stress waves and splitting forces to significantly improve the crushing efficiency of high-hardness rocks. This is similar to the explosion principle in the drilling and blasting method. The explosion will also generate strong impact and gas expansion force inside the rock, resulting in the crushing of the rock. Compared with the drilling and blasting method, the mining device of the present application is safer, has less environmental impact, and has higher efficiency and more advantages.

[0010] In a preferred implementation, the splitting module includes a plurality of widening pieces, and a first impact piece and a second impact piece are respectively provided on the upper side and the lower side of the widening piece, and stress waves formed by the first impact piece and the second impact piece impacting the rock can intersect.

[0011] When the first impact piece and the second impact piece work at the same time, the stress waves they generate will intersect inside the rock. Due to the superposition effect of the stress waves, the stress at the intersection will be significantly enhanced, making it easier to generate cracks or damage inside the rock. Once the cracks are formed, they will expand along the weak surface or weak area of ​​the rock, thereby accelerating the splitting process of the rock.

[0012] In a preferred implementation, the inner wall surface of the borehole that the widening member contacts is the same as the inner wall surface of the borehole that the impact member contacts.

[0013] When the inner wall surface of the borehole contacted by the widening piece is the same as the inner wall surface of the borehole contacted by the impact piece, when the impact piece and the widening piece apply force in the same direction, their forces will produce a superposition effect, forming a larger combined force, which can act on the rock more effectively, increase the splitting effect, and cause the basalt to fracture more quickly.

[0014] In a preferred implementation, the inner wall surface of the borehole contacted by the widening member and the inner wall surface of the borehole contacted by the impact member are perpendicular to each other.

[0015] The widening piece applies pressure in the horizontal direction, causing compressive stress in the rock in that direction, while the impact piece generates stress waves in the vertical direction, resulting in tensile stress concentration. This orthogonal distribution of tensile and compressive stresses is conducive to forming a larger stress difference inside the rock, thereby promoting the formation and expansion of cracks and improving mining efficiency and effectiveness.

[0016] In a preferred implementation, the impact member includes a swing rod and an impact hammer disposed at the end of the swing rod, and the impact power device can drive the swing rod to swing back and forth so that the impact hammer impacts the inner wall of the drill hole.

[0017] In a preferred implementation, the impact power device includes a cam, an elastic member and an articulated seat, the rocker arm is rotatably arranged on the articulated seat, the articulated seat is arranged on a fixed platform, the elastic member bypasses the rocker arm and is fixed to the fixed platform, and the cam rotates and abuts against the rocker arm to cause the rocker arm to swing back and forth.

[0018] In a preferred implementation, the impact module and the splitting module are integrated into a mining shell, and the splitting module and the impact module are independently arranged in different cavities in the mining shell to work independently.

[0019] The splitting module and impact module can be maintained, replaced or upgraded independently to improve operation stability.

[0020] In a preferred implementation, the impact piece can move to a first position and a second position. When the impact piece is in the first position, the impact module and the splitting module are placed in the borehole. When the impact piece is in the second position, the impact piece contacts the inner wall of the borehole for impact.

[0021] In a preferred implementation, a control module is also included, which includes a camera and a control system. The camera can monitor the generation of rock cracks inside the borehole and the rock crushing process in real time, and control the impact frequency of the impact piece to achieve accurate and efficient crushing.

[0022] The camera monitors the generation of rock cracks inside the borehole and the rock crushing process in real time, and can control the impact frequency of the impact piece accordingly to achieve accurate and efficient crushing, real-time feedback, and precise control.

[0023] The method for using the basalt mining device comprises the following steps:

[0024] S1: Before starting use, use a drilling tool to drill a hole in the rock and put in the basalt mining device;

[0025] S2: The hydraulic power drive device is started to work, so that the widening member contacts the inner wall of the borehole, so that the mining shell is stably located in the borehole, and the hydraulic power drive device is stopped;

[0026] S3: The hydraulic power drive device and the impact power device are operated at the same time. The impact hammer repeatedly hits the hole wall, which can generate high-frequency impact force inside the rock. This impact force will quickly form stress waves inside the rock, and then produce complex stress distribution in the rock, destroying the original structure of the rock and promoting the expansion and penetration of cracks. The widening piece applies a splitting force inside the rock, and through a composite action mode, the rock is gradually cracked and broken inside, which more effectively destroys the structure of the rock;

[0027] S4: During the crushing process, the staff can use the camera to monitor the expansion of rock cracks inside the borehole in real time, so as to control the impact frequency and activation of the impact piece accordingly, and realize accurate, efficient and energy-saving crushing operations.

[0028] The above structure has the following beneficial effects:

[0029] 1. The basalt mining device of the present invention can directly act on the weak surface of the rock through repeated hammering and splitting methods, thereby improving the crushing efficiency, especially for basalt with greater hardness, allowing the rock to be gradually crushed, especially after cracks are formed inside the rock, subsequent hammering and splitting operations can more effectively expand the cracks and improve the crushing efficiency.

[0030] 2. Compared with one-time high-energy blasting and splitting that requires greater hydraulic kinetic energy, the basalt mining device of the present invention uses a method of repeated hammering and splitting that is more controllable and uniform in energy consumption, can greatly reduce energy consumption, and reduce mining costs.

[0031] 3. The basalt mining device of the present invention can control the degree of rock crushing more accurately by repeated hammering and splitting, especially in the case where rocks of specific sizes are required, this method can provide a more flexible solution.

[0040] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0041] The present invention will be described below in conjunction with the accompanying drawings.

[0042] The specific plans adopted are:

[0043] like Figure 1-5 As shown, the present invention provides a basalt mining device, comprising an impact module and a splitting module placed inside a borehole;

[0044] The impact module includes an impact piece and an impact power device 21 for driving the impact piece 20 to impact the inner wall of the borehole. The impact power device can drive the impact piece 20 to impact the inner wall of the borehole. The impact force forms a stress wave inside the rock, so that stress changes occur inside the rock, changing the original structure of the rock.

[0045] The splitting module includes a widening member 30 and a hydraulic power drive device 31 for driving the widening member to expand the borehole. The widening member 30 applies a splitting force to the rock from inside the borehole to open the cracks in the rock. The impact power device and the hydraulic power drive device are in operation, and through the combined action of the impact force and the splitting force, a complex stress distribution is generated in the rock, causing the rock to crack and break internally, thereby improving the crushing efficiency.

[0046] The basalt mining device of the present invention simultaneously arranges an impact module and a splitting module in the borehole 40 of the basalt to crush the rock. The impact module can cause multiple damages inside the rock by generating stress waves, thereby effectively reducing the overall strength of the basalt. The splitting device further expands the borehole, and utilizes the characteristic that the tensile strength of the rock is much lower than the compressive strength, so that the rock is easier to be crushed. This combined use method can combine the effects of stress waves and splitting forces to significantly improve the crushing efficiency. For high-hardness basalt, due to its high compressive strength and wear resistance, simple splitting is difficult to achieve an ideal crushing effect, and the stress wave generated by the impact module can form microcracks inside the rock, reducing its integrity, making it easier for the splitting device to expand the borehole, which is different from the drilling and blasting method. The principle of explosion is similar to that of rock blasting. The explosion will also produce a strong impact inside the rock, causing the rock to break. Why does the stress wave generated by the impact piece inside the rock change the original structure of the rock and make it easier to break? This is mainly attributed to the complex mechanical effects produced when the stress wave propagates inside the rock. When the stress wave encounters the weak surface of the rock or the interface of different media, reflection, refraction and interference will occur, resulting in redistribution of stress inside the rock. In some areas, the stress will be superimposed and enhanced, exceeding the tensile or compressive strength of the rock, thereby causing the generation and expansion of cracks. Once these cracks are formed, they will destroy the integrity of the rock, reduce its strength, and make it easier to further break. Compared with the drilling and blasting method, the mining device of the present application is safer, has less environmental impact, and has higher efficiency and more advantages.

[0047] As a preferred embodiment of the present application, the splitting module includes a plurality of widening members 30, and a first impact member and a second impact member are respectively provided on the upper side and the lower side of the widening member, and stress waves formed by the first impact member and the second impact member impacting the rock can intersect.

[0048] The splitting module is based on the principle of an existing splitting rod. A first impact piece and a second impact piece are respectively arranged on the upper and lower sides of the widening piece of the splitting module, and the stress waves formed by the two impact pieces impacting the rock can intersect. Such a design helps the widening piece to split the rock more easily. When the first impact piece and the second impact piece work at the same time, the stress waves they generate will intersect inside the rock. Due to the superposition effect of the stress waves, the stress at the intersection will be significantly enhanced, making it easier to generate cracks or damage inside the rock. Once the cracks are formed, they will expand along the weak surface or weak area of ​​the rock, thereby accelerating the splitting process of the rock. By arranging two impact pieces 20 and making their stress waves intersect, energy can be used more effectively and more energy can be concentrated in the working area of ​​the splitting device, thereby improving the splitting efficiency.

[0049] As a preferred embodiment of this embodiment, see Figure 1 , Figure 3 and Figure 4 , the inner wall surface of the borehole that the widening piece contacts is the same surface as the inner wall surface of the borehole that the impact piece contacts. When the inner wall surface of the borehole that the widening piece contacts is the same surface as the inner wall surface of the borehole that the impact piece contacts, when the impact piece and the widening piece apply force in the same direction, their forces will produce a superposition effect, forming a larger combined force, which can act on the rock more effectively, increase the splitting effect, and cause the basalt to break faster.

[0050] As a preferred embodiment of this embodiment, see Figure 2 The inner wall surface of the borehole contacted by the widening member 30 and the inner wall surface of the borehole contacted by the impact member are perpendicular to each other.

[0051] Setting the impact piece 20 on a vertical plane perpendicular to the contact surface of the widening piece 30 helps to quickly crack high-hardness basalt. The principle of this design can be explained in detail as follows: rock splitting is mainly achieved by generating tensile stress inside the rock through external force. When the tensile stress exceeds the tensile strength of the rock, the rock will crack along a certain direction and then break. When the impact piece 20 and the widening piece 30 work together, the widening piece is mainly used to apply pressure on the inner wall of the borehole to expand existing cracks or generate new cracks, while the impact piece induces dynamic stress concentration inside the rock by generating stress waves. When the impact piece is set on a vertical plane perpendicular to the contact surface of the widening piece, the action directions of the two form an orthogonal relationship, which is particularly important for splitting high-hardness basalt. The stress wave and impact force generated by the impact piece help guide the crack to expand along a predetermined direction, that is, perpendicular to the expansion direction of the widening piece 30. This direction control can ensure that the crack expands more regularly and continuously, thereby improving the efficiency and effect of splitting.

[0052] Due to its high hardness and dense structure, basalt usually requires a greater external force to break it. Specifically, the widening member 30 applies pressure in the horizontal direction, causing the rock to generate compressive stress in that direction, while the impact member generates stress waves in the vertical direction, resulting in tensile stress concentration. This orthogonal distribution of tensile and compressive stress is conducive to forming a greater stress difference inside the rock, thereby promoting the formation and expansion of cracks.

[0053] In addition, high-hardness basalt often has more microcracks and weak surfaces. When the stress wave generated by the impact piece encounters these microcracks or weak surfaces, it will cause them to expand. Since the impact piece 20 is perpendicular to the direction of the widening piece 30, the stress wave is more likely to propagate in a direction perpendicular to the direction of action of the widening piece, thereby forming large cracks in these directions. This design can more effectively split high-hardness basalt and improve mining efficiency and effectiveness.

[0054] As a preferred embodiment of the present application, the impact piece has both a drilling surface in contact with the widening piece and a drilling surface perpendicular to the widening piece. Since the impact piece contacts the inner wall of the borehole in two different directions, it can generate multi-directional stress distribution inside the rock, which can increase the complexity of the stress wave inside the rock. The drilling surface in contact with the widening piece can transmit direct splitting force, while the drilling surface perpendicular to the widening piece may assist the splitting process by generating shear force or torsional force. This synergistic effect can make the rock easier to break and increase the accuracy and efficiency of splitting.

[0055] As a preferred embodiment of the present application, the impact member 20 includes a pendulum rod 200 and an impact hammer 201 disposed at the end of the pendulum rod, and the impact power device 21 can drive the pendulum rod 200 to swing back and forth so that the impact hammer 201 impacts the inner wall of the drill hole.

[0056] The impact member 20 is configured as a structure of a pendulum rod 200 and an impact hammer 201. The impact hammer can accumulate potential energy during the swinging process and release it instantly when hitting the basalt, thereby transferring the energy to the basalt efficiently and concentratedly. This energy transfer helps to form a strong stress wave inside the rock, thereby more effectively causing the rock to fracture and split. The structure of the pendulum rod 200 and the impact hammer 201 can be adjusted and optimized according to actual needs, by adjusting the weight, swing angle and speed, shape and other parameters of the impact hammer to adapt to different rock hardness, drilling diameter and depth and other conditions.

[0057] See also Figure 5 The impact power device 21 includes a cam 210, an elastic member 211 and an articulated seat 212. The swing rod is rotatably arranged on the articulated seat, and the articulated seat is arranged on the fixed platform 11. The elastic member bypasses the swing rod and is fixed on the fixed platform. The cam rotates and abuts against the swing rod to make the swing rod swing back and forth.

[0058] Specifically, the articulated seat 212 provides a rotation fulcrum for the swing rod, so that it can swing around a fixed point. The cam, as a power source, drives the swing rod to swing back and forth by rotating it to abut against the swing rod. When the swing rod is pushed to one side by the high point of the cam, the elastic member, such as a spring, is stretched and stores energy; when the low point of the cam abuts against the swing rod, the elastic member releases the stored energy, pushing the swing rod to swing to the other side, driving the impact hammer to hammer the inner wall of the drill hole. This process of energy storage and release not only improves the efficiency of energy utilization, but also helps to achieve continuous and stable swinging of the swing rod.

[0059] The power source of the cam can be a servo motor or other existing power units. The existing technology is used to adjust the rotation speed. The shape of the cam, the elasticity of the elastic part and the length of the rocker arm can be replaced, so that the impact power device can adapt to different work needs and scenarios. Whether it is high-frequency or low-frequency swing, or a strong or small force impact, it can be achieved by adjusting the device parameters.

[0060] As a preferred embodiment of the present application, see Figure 1 and Figure 2 The impact module and the splitting module are integrated into a mining shell 10, and the splitting module and the impact module are independently arranged in different cavities in the mining shell to work independently.

[0061] The impact module and the splitting module are integrated into a mining shell, and the splitting module and the impact module are independently arranged in different cavities in the mining shell 10 to work independently, so that the splitting module and the impact module can be independently maintained, replaced or upgraded. The operator can independently adjust the working parameters of the impact module and the splitting module, such as impact frequency, impact force, splitting speed, etc., according to factors such as the properties of the rock and mining requirements, so as to achieve the best mining effect and adapt to the mining needs of rocks of different types and hardness.

[0062] This modular design not only reduces the complexity of maintenance, but also improves the maintainability of the equipment, making on-site operation more convenient, without interfering with each other, and improving stability. In order to make the two modules work independently, the working state of one module will not affect the other module. For example, rubber pads or vibration isolators can be set in the mining shell to absorb and reduce the vibration energy generated by the impact module. The vibration or impact generated by the impact module will not affect the accuracy and stability of the splitting module, thereby ensuring that the entire mining process is smoother and more reliable.

[0063] As a preferred embodiment of the present application, the impact piece can move to a first position and a second position. When the impact piece is in the first position, the impact module and the splitting module are placed in the borehole. When the impact piece is in the second position, the impact piece contacts the inner wall of the borehole for impact.

[0064] When the impact piece is in the first position, that is, the minimum diameter of the device, the impact module and the splitting module can be smoothly placed in the borehole 40. According to this size, the borehole diameter is reasonably designed to prepare for subsequent rock crushing. The impact piece shown in the figure is located outside the mining shell. It can be understood that the first position of the impact piece of the present application can be located inside the mining shell, and when the impact piece moves to the second position, it contacts the inner wall of the borehole for impact, effectively transfers energy and generates stress waves, thereby promoting rock crushing.

[0065] As a preferred embodiment of the present application, a control module is also included, which includes a camera and a control system. The camera can monitor the generation of rock cracks inside the borehole and the rock crushing process in real time, and control the impact frequency of the impact piece to achieve accurate and efficient crushing.

[0066] The camera monitors the rock crack generation and rock crushing process inside the borehole in real time, and can control the impact frequency of the impact piece accordingly to achieve accurate and efficient crushing, real-time feedback, and precise control: The camera captures the rock crack generation and crushing process inside the borehole in real time, and the operator can instantly obtain the dynamic response information of the rock. This real-time feedback allows the impact frequency of the impact piece to be accurately adjusted according to the actual state of the rock. Precise control of the impact frequency helps avoid unnecessary energy waste. When the camera detects that the rock has generated enough cracks or is about to break, the impact frequency can be appropriately reduced to reduce excessive energy input. Conversely, if the rock does not respond well to the impact, the impact frequency can be appropriately increased to improve the crushing efficiency. This optimization of energy management can significantly improve the energy efficiency of the mining process.

[0067] The method for using the basalt mining device comprises the following steps:

[0068] S1: Before starting use, use a drilling tool to drill a hole in the rock and put in the basalt mining device;

[0069] S2: The hydraulic power drive device is started to work, so that the widening member contacts the inner wall of the borehole, so that the mining shell is stably located in the borehole, and the hydraulic power drive device is stopped;

[0070] S3: The hydraulic power drive device and the impact power device are operated at the same time. The impact hammer repeatedly hits the hole wall, which can generate high-frequency impact force inside the rock. This impact force will quickly form stress waves inside the rock, and then produce complex stress distribution in the rock, destroying the original structure of the rock and promoting the expansion and penetration of cracks. The widening piece applies a splitting force inside the rock, and through a composite action mode, the rock is gradually cracked and broken inside, which more effectively destroys the structure of the rock;

[0071] S4: During the crushing process, the staff can use the camera to monitor the expansion of rock cracks inside the borehole in real time, so as to control the impact frequency and activation of the impact piece accordingly, and realize accurate, efficient and energy-saving crushing operations.

This impact force will quickly form stress waves inside the rock, and then produce complex stress distribution in the rock, destroying the original structure of the rock and promoting the expansion and penetration of cracks. The widening piece applies a splitting force inside the rock, and through a composite action mode, the rock is gradually cracked and broken inside, which more effectively destroys the structure of the rock; S4: During the crushing process, the staff can monitor the expansion of rock cracks inside the borehole in real time through the camera, so as to control the impact frequency and activation of the impact piece accordingly, and realize accurate, efficient and energy-saving crushing operations.
