Description
Technical Field
[0001] This invention relates to the field of marble mining technology, and in particular to a mining and tunneling device for marble mines. Background Technology
[0002] Marble, as a high-quality stone that combines decoration and practicality, is widely used in architectural decoration, sculpture art and engineering construction. As market demand for it continues to grow with the acceleration of urbanization, the efficiency, safety and protection of marble in the mining and excavation of marble mines, as the first link in stone production, directly affect the subsequent processing costs and the economic value of the stone.
[0003] Currently, the main marble quarrying methods on the market rely on traditional blasting and mechanical cutting. While blasting is highly efficient, it easily causes internal cracks and surface damage to the marble, reducing the yield and economic value of the stone. Mechanical cutting uses wire saws for quarrying, which can reduce damage to the stone to some extent. However, existing wire saws can only perform cutting operations, and drilling requires other equipment, thus increasing the marble quarrying cycle. To solve this problem, existing technology integrates the drilling and cutting mechanisms into the same device, shortening the quarrying cycle through coordinated drilling and cutting. However, in actual use, because the distance between the guide wheel and the wire saw disc is fixed, when the cutting path needs to be frequently turned, it is impossible to maintain the tension of the marble wire saw at all times, resulting in cutting jerks, which in turn reduces the cutting efficiency of the device and affects the cutting quality. Summary of the Invention
[0004] The purpose of this invention is to provide a mining and tunneling device for marble mines, which solves the problem in the prior art that the marble wire saw cannot be kept under constant tension during use, resulting in cutting interruptions.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a marble quarrying and tunneling device, comprising a base, an organic body on the top of the base, a tensioning mechanism on the front side of the organic body for convenient adjustment of the tension of the wire saw, a drilling mechanism on the right side of the organic body for convenient drilling of the marble quarry, a separation mechanism on the top of the organic body for convenient clamping of ore blocks of different sizes, and a propulsion mechanism inside the base for convenient control of the mining and tunneling depth and feed rate of the marble quarry. The tensioning mechanism includes a connecting frame and a connecting rod. The connecting frame is fixedly connected to the front side of the base. A worm gear is rotatably connected to the right side of the connecting frame. The left end of the worm gear passes through the connecting frame and is rotatably connected to the inside left side of the connecting frame. A rotating rod is rotatably connected to the inside rear side of the connecting frame. A worm wheel is fixedly connected to the front end of the rotating rod, and the worm wheel meshes with the worm gear. A fixed shaft is fixedly connected to the front side of the worm wheel. A first rotating shaft is rotatably connected to the front side of the fixed shaft. A hollow frame is provided on the front side of the connecting frame. A second rotating shaft is rotatably connected to the top of the hollow frame. The second rotating shaft is connected to the first rotating shaft through the connecting rod. An adjustment component is provided on the inside side of the connecting frame.
[0006] With the above technical solution, when the worm gear is rotated, the worm wheel that meshes with it will rotate synchronously. This rotation process can effectively drive the first rotating shaft to rotate. At the same time, the second rotating shaft is connected to the first rotating shaft through a connecting rod. Therefore, when the first rotating shaft rotates, the second rotating shaft will also rotate. This linkage mechanism allows the hollow frame to move smoothly upward in the internal space of the connecting frame. During this process, the guide wheel installed on the front side of the I-beam will also move accordingly, ensuring that the diamond wire saw is always in an ideal tension state throughout the entire cutting process. This continuous tension can effectively avoid the stuttering phenomenon during the cutting process, thereby significantly improving the cutting efficiency of the device.
[0007] Preferably, the drilling mechanism includes an electric slide rail, which is fixedly connected to the right side of the machine body. A movable seat is slidably connected inside the electric slide rail. Multiple hollow columns are fixedly connected at equal intervals around the right side of the movable seat. A tension spring is fixedly connected to the left side inside the hollow column. A support column is fixedly connected to the right end of the tension spring. A limit rod is threaded to the top of the support column. One end of each of the multiple limit rods passes through the corresponding support column. A drilling assembly is provided in the middle of the right side of the movable seat.
[0008] Through the above technical solution, the electric slide rail can drive the moving seat to move vertically up and down. During this process, the drilling component fixed on the moving seat will also move synchronously. This design allows users to flexibly adjust the drilling height of the device according to the actual usage scenario and specific needs to adapt to drilling operations at different heights. When drilling, first unscrew the limit rod to release the fixed limit on the support column, allowing the support column to slide freely inside the hollow column. At this time, the support columns distributed around the perimeter will play a key supporting role, ensuring that the drill bit remains horizontal during drilling. This structural design effectively ensures the accuracy of drilling operations.
[0009] Preferably, the separation mechanism includes a support base, which is fixedly connected to the top of the machine body. A U-shaped plate is fixedly connected to the top of the support base. An electric push rod is fixedly connected to the bottom inner side of the U-shaped plate. A placement plate is fixedly connected to the output end of the electric push rod. A rotating rod is rotatably connected to the inner side of the placement plate. A hollow plate is fixedly connected to the right side of the rotating rod. Torsion springs are provided on both the front and rear sides of the outer wall of the rotating rod. One end of the torsion spring is fixedly connected to the hollow plate, and the other end of the torsion spring is fixedly connected to the inner side of the placement plate. A servo motor is fixedly connected to the right side of the hollow plate. The output end of the servo motor passes through the torsion spring and is fixedly connected to a bidirectional lead screw. Clamping plates are threaded to the left and right sides of the outer wall of the bidirectional lead screw. A rubber pad is fixedly connected to one side of the clamping plate. A pushing assembly is provided on the right side of the U-shaped plate.
[0010] Through the above technical solution, the robotic arm can precisely drive the hydraulic rod to move until the push plate pushed by the hydraulic rod makes close contact with the hard marble block. At the same time, the servo motor drives the bidirectional lead screw to rotate smoothly and orderly. As the bidirectional lead screw rotates, the clamping plate fixed on it will also move to the middle position to effectively limit and clamp the block. In this way, not only is the stability of the block ensured during the processing, but the integrity of the stone can also be protected to the greatest extent.
[0011] Preferably, the propulsion mechanism includes a stepper motor, which is fixedly connected to the inside left side of the base. The output end of the stepper motor is fixedly connected to a threaded rod II. A moving block is threadedly connected to the outer side of the threaded rod II. L-shaped plates are fixedly connected to the front and rear sides of the moving block. A gear shaft is rotatably connected to the bottom inner side of the L-shaped plate. The top end of the gear shaft is rotatably connected to the bottom of the machine body. A rack is fixedly connected to the front and rear sides of the inside of the base. The two gear shafts are respectively meshed with the corresponding racks.
[0012] By using the above technical solution, the stepper motor is started, which drives the threaded rod to rotate. The moving block moves accordingly. The cooperation between the gear shaft and the rack makes the machine body move more smoothly on the base, thus ensuring the accuracy of subsequent work.
[0013] Preferably, the adjustment assembly includes a hollow fixed plate and a connecting plate. The hollow fixed plate is fixedly connected inside the connecting frame. A micro motor is fixedly connected to both the left and right sides of the connecting frame. The output end of the micro motor passes through the hollow fixed plate and is fixedly connected to a threaded rod. A movable block is threadedly connected to the outer side of the threaded rod. A movable shaft is fixedly connected to the front side of the movable block. A support plate is provided on the front side of the hollow fixed plate. Movable shafts are rotatably connected to the left and right ends of the rear side of the support plate. The two movable shafts are respectively connected to the corresponding movable shafts through the connecting plate. A hollow rod is fixedly connected to the front side of the support plate. A movable rod is slidably connected inside the hollow rod. The top end of the movable rod is fixedly connected to the bottom of the I-shaped plate. An I-shaped plate is fixedly connected to the bottom end of the hollow rod. Guide wheels are rotatably connected to the front sides of both the I-shaped plate and the I-shaped plate.
[0014] With the above technical solution, the micro motor on one side is started, which can drive the threaded rod to rotate. The movable block on its outer side will move linearly along the spiral trajectory of the threaded rod. At this time, the movable shaft one connected to the movable block will also rotate. The movable shaft two will also rotate through the connecting plate. Since the I-shaped plate one rotates inside the hollow frame, it can drive the two guide wheels to adjust the left and right angles at the same time, so as to meet different cutting environments.
[0015] Preferably, the drilling assembly includes a stepper motor, which is fixedly connected to the middle right side of the moving base. A hollow shaft is provided on the outer side of the output end of the drilling assembly. A drill bit is fixedly connected to the right end of the hollow shaft. A bolt is threadedly connected to the front side of the hollow shaft. The rear end of the bolt passes through the hollow shaft and the output end of the stepper motor in sequence.
[0016] Using the above technical solution, starting the stepper motor can drive the drill bit to rotate, thus completing the drilling work of the ore body. Loosening the bolts can release the limit on the hollow shaft, at which point the excessively damaged drill bit can be replaced.
[0017] Preferably, the pushing assembly includes a robotic arm, which is fixedly connected to the right side of the U-shaped plate. A hydraulic rod is fixedly connected to the right end of the robotic arm, and a push plate is fixedly connected to the output end of the hydraulic rod.
[0018] The above technical solution allows the hydraulic rod to move the push plate left and right, facilitating the normal operation of subsequent ore body separation.
[0019] Preferably, a servo motor is fixedly connected to the front of the machine body, and the output end of the servo motor passes through the base and is fixedly connected to a wire saw disc. The same diamond wire saw is provided on the outer side of the wire saw disc and the guide wheel.
[0020] With the above technical solution, the diamond wire saw can be installed on the wire saw disc and guide wheel to facilitate the normal operation of subsequent cutting work.
[0021] Preferably, the bottom right front and rear ends of the base are rotatably connected to walking wheels, the bottom left front and rear ends of the base are fixedly connected to reinforcing seats, and the left outer wall of the base is fixedly connected to an anti-slip sleeve.
[0022] The above technical solution allows the device to be moved easily, and the reinforcement base further increases the stability of the device.
[0023] Preferably, a protective plate is fixedly connected to the left side of the machine body, and a control panel is fixedly connected to the left side of the protective plate. The control panel is electrically connected to a micro motor, a servo motor, an electric slide rail, a stepper motor, an electric push rod, a servo motor, a robotic arm, a hydraulic rod, and a stepper motor, respectively.
[0024] The above technical solutions can be used to control the operation of micro motors, servo motors, electric slide rails, stepper motors, electric push rods, servo motors, robotic arms, hydraulic rods, and stepper motors.
[0025] In summary, the present invention has at least one of the following beneficial technical effects: 1. This invention utilizes a worm gear that rotates to drive the first rotating shaft, which in turn rotates the second rotating shaft via a connecting rod. This causes the hollow frame to move upwards within the connecting frame, and the guide wheel on the front side of the I-beam plate moves accordingly. This ensures that the diamond wire saw remains taut during cutting, minimizing cutting interruptions and improving cutting efficiency and quality. Simultaneously, a micro motor on one side is activated, driving the threaded rod to rotate. The movable block on the threaded rod moves accordingly, causing the movable shaft to rotate. The movable shaft, via the connecting plate, also rotates, allowing for simultaneous adjustment of the angles of the two guide wheels to accommodate different cutting environments.
[0026] 2. This invention uses an electric slide rail to move the movable seat up and down, and the drilling assembly on the movable seat will move accordingly. The drilling height of the device can be adjusted according to actual usage requirements. When drilling, first align the drill bit with the drilling position, and then unscrew the limit rod to release the limit on the support column. At this time, the support column will slide inside the hollow column. The support columns around the perimeter can prevent the drill bit from tilting during use, thereby ensuring the accuracy of drilling.
[0027] 3. This invention uses a robotic arm to move a hydraulic rod toward the marble block until the push plate contacts the marble block, which can move the marble block forward. At the same time, a servo motor can drive a bidirectional lead screw to rotate, and the clamping plate on the bidirectional lead screw will move toward the center to limit and clamp the block. It can limit and clamp blocks of different sizes to prevent them from tipping over during the separation process, thereby maximizing the protection of the integrity of the stone.

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 12 The present invention will be further described in detail below.
[0031] This invention provides a mining and tunneling device for marble mines, including a base 1, a body 2 on the top of the base 1, a tensioning mechanism 3 on the front side of the body 2 for convenient adjustment of the tension of the wire saw, a drilling mechanism 4 on the right side of the body 2 for convenient drilling of the marble mine, a separation mechanism 5 on the top of the body 2 for convenient clamping of ore blocks of different sizes, and a propulsion mechanism 6 inside the base 1 for convenient control of the mining and tunneling depth and feed speed of the marble mine. The tensioning mechanism 3 includes a connecting frame 31 and a connecting rod 311. The connecting frame 31 is fixedly connected to the front side of the base 1. A worm gear 32 is rotatably connected to the right side of the connecting frame 31. The left end of the worm gear 32 passes through the connecting frame 31 and is rotatably connected to the left side inside the connecting frame 31. A rotating rod 33 is rotatably connected to the rear side inside the connecting frame 31. A worm wheel 34 is fixedly connected to the front end of the rotating rod 33. The worm wheel 34 meshes with the worm gear 32. A fixed shaft 35 is fixedly connected to the front side of the worm wheel 34. A first rotating shaft 3 is rotatably connected to the front side of the fixed shaft 35. 6. A hollow frame 37 is provided on the front side of the connecting frame 31. A second rotating shaft 310 is rotatably connected to the top of the hollow frame 37. The second rotating shaft 310 is connected to the first rotating shaft 36 through a connecting rod 311. An adjusting assembly 39 is provided on the inner side of the connecting frame 31. The adjusting assembly 39 includes a hollow fixing plate 391 and a connecting plate 398. The hollow fixing plate 391 is fixedly connected to the inside of the connecting frame 31. Micro motors 392 are fixedly connected to both the left and right sides of the connecting frame 31. The output end of the micro motor 392 passes through the hollow fixing plate 391 and... A threaded rod 393 is fixedly connected, and a movable block 394 is threadedly connected to the outer side of the threaded rod 393. A movable shaft 395 is fixedly connected to the front side of the movable block 394. A support plate 396 is provided on the front side of the hollow fixed plate 391. Movable shafts 397 are rotatably connected to the left and right ends of the rear side of the support plate 396. The two movable shafts 397 are respectively connected to the corresponding movable shafts 395 through connecting plates 398. A hollow rod 399 is fixedly connected to the front side of the support plate 396, and a movable shaft 395 is slidably connected inside the hollow rod 399. The top of the movable rod 3910 is fixedly connected to the bottom of the I-shaped plate 38. The bottom of the hollow rod 399 is fixedly connected to the I-shaped plate 3911. The front sides of both the I-shaped plate 38 and the I-shaped plate 3911 are rotatably connected to guide wheels 3912. The front side of the machine body 2 is fixedly connected to a servo motor 3913. The output end of the servo motor 3913 passes through the base 1 and is fixedly connected to a wire saw disc 3914. The wire saw disc 3914 and the outer side of the guide wheel 3912 are provided with the same diamond wire saw 3915. Specifically, when the worm gear 32 is rotated, the worm wheel 34, which meshes tightly with it, will rotate synchronously. This rotation process can effectively drive the first rotating shaft 36 to rotate. At the same time, the second rotating shaft 310 will also rotate with the first rotating shaft 36 through the transmission of the connecting rod 311. This causes the hollow frame 37 to move upward in the internal space of the connecting frame 31. As the hollow frame 37 rises, the movable rod 3910 inside the hollow rod 399 will also move upward. The guide wheel 3912 on the front side of the I-beam plate 38 will also move accordingly. This design ensures that the diamond wire saw 3915 is always in a tensioned state during the cutting process, avoiding possible stuttering during the cutting process, thereby significantly improving the cutting efficiency of the device. In actual use, when the cutting angle needs to be adjusted according to specific requirements, the micro motor 392 can drive the threaded rod 393 to rotate. The movable block 394 on the threaded rod 393 will move with the rotation of the thread. At this time, the movable shaft 395 will rotate with the movement of the movable block 394. The movable shaft 397 will also rotate synchronously through the action of the connecting plate 398. Since the I-shaped plate 38 is rotatably installed inside the hollow frame 37, it can simultaneously drive the two guide wheels 3912 to adjust the left and right angles, thereby ensuring the accuracy and efficiency of the cutting process.
[0032] The drilling mechanism 4 includes an electric slide rail 41, which is fixedly connected to the right side of the body 2. A movable seat 42 is slidably connected inside the electric slide rail 41. Multiple hollow columns 43 are fixedly connected at equal intervals around the right side of the movable seat 42. A tension spring 44 is fixedly connected to the left side inside the hollow column 43. A support column 45 is fixedly connected to the right end of the tension spring 44. A limit rod 46 is threadedly connected to the top of the support column 45. One end of each limit rod 46 passes through the corresponding support column 45. A drilling assembly 47 is provided in the middle right side of the movable seat 42. The drilling assembly 47 includes a stepper motor 471, which is fixedly connected to the middle right side of the movable seat 42. A hollow shaft 472 is provided on the outer side of the output end of the drilling assembly 47. A drill bit 473 is fixedly connected to the right end of the hollow shaft 472. A bolt 474 is threadedly connected to the front side of the hollow shaft 472. The rear end of the bolt 474 passes through the hollow shaft 472 and the output end of the stepper motor 471 in sequence. Specifically, the movable seat 42 can be moved to a pre-set designated position via the electric slide rail 41. As the movable seat 42 moves, the drilling assembly 47 mounted on the movable seat 42 will also move synchronously. At the same time, the stepper motor 61 is started to drive the threaded rod 62 to rotate. The rotation of the threaded rod 62 will drive the connected movable block 63 to move linearly, so that the machine body 2 can move smoothly and without shaking on the base 1 until the drill bit 473 first contacts the surface of the ore body. Then, the limit rod 46 is unscrewed to release the limit on the support column 45. At this time, the support column 45 can slide inside the hollow column 43 through the tension spring 44. Through the combined action of the evenly distributed support columns 45, it can be ensured that the drill bit 473 remains horizontal during use and will not produce any tilt angle, thereby ensuring the verticality and accuracy of the drilling. Then, the stepper motor 471 is started, and the stepper motor 471 drives the drill bit 473 to rotate at high speed, thereby successfully completing the drilling work.
[0033] The separation mechanism 5 includes a support base 51, which is fixedly connected to the top of the body 2. A U-shaped plate 52 is fixedly connected to the top of the support base 51. An electric push rod 53 is fixedly connected to the bottom inner side of the U-shaped plate 52. A placement plate 54 is fixedly connected to the output end of the electric push rod 53. A rotating rod 55 is rotatably connected to the inner side of the placement plate 54. A hollow plate 56 is fixedly connected to the right side of the rotating rod 55. Torsion springs 57 are provided on both the front and rear sides of the outer wall of the rotating rod 55. One end of the torsion spring 57 is fixedly connected to the hollow plate 56, and the other end of the torsion spring 57 is fixedly connected to the inner side of the placement plate 54. A servo motor 58 is fixedly connected to the right side of the hollow plate 56.

The outer walls of the bidirectional lead screw 510 are threaded with clamping plates 511 on both the left and right sides. A rubber pad 512 is fixedly connected to one side of the clamping plate 511. A push assembly 59 is provided on the right side of the U-shaped plate 52. The push assembly 59 includes a robotic arm 591. The robotic arm 591 is fixedly connected to the right side of the U-shaped plate 52. A hydraulic rod 592 is fixedly connected to the right end of the robotic arm 591. A push plate 593 is fixedly connected to the output end of the hydraulic rod 592. Specifically, the robotic arm 591 first effectively drives the hydraulic rod 592 closer to the marble block until the push plate 593 makes close contact with the surface of the marble block. Then, the hydraulic rod 592 is activated to smoothly push the marble block forward, causing it to tilt to a certain extent. At the same time, the servo motor 58 drives the bidirectional lead screw 510 to rotate. As the bidirectional lead screw 510 rotates, the clamping plate 511 on it moves synchronously to the middle position, thereby providing a stable limit clamping for the block. When the machine body 2 begins to move to the left, the block will also tilt accordingly. At this time, the hollow plate 56, under the elastic action of the torsion spring 57, will adjust accordingly to the tilt angle of the block, thereby achieving flexible limit clamping for blocks of different sizes, preventing the block from tipping over during the separation process, ensuring the stability of the block during operation, and thus maximizing the protection of the stone's integrity.
[0034] The propulsion mechanism 6 includes a stepper motor 61, which is fixedly connected to the inside left side of the base 1. The output end of the stepper motor 61 is fixedly connected to a threaded rod 62. The outer side of the threaded rod 62 is threadedly connected to a moving block 63. The front and rear sides of the moving block 63 are fixedly connected to L-shaped plates 64. The bottom inner side of the L-shaped plate 64 is rotatably connected to a gear shaft 65. The top end of the gear shaft 65 is rotatably connected to the bottom of the body 2. The front and rear sides of the inside of the base 1 are fixedly connected to racks 66. The two gear shafts 65 are respectively meshed with the corresponding racks 66. Specifically, starting the stepper motor 61 can effectively drive the threaded rod 62 to rotate. As the threaded rod 62 rotates, the moving block 63 connected to it will also move. Through the precise cooperation between the gear shaft 65 and the rack 66, the machine body 2 can slide smoothly on the base 1. This design not only reduces frictional resistance, but also greatly improves the stability of movement.
[0035] The bottom right front and rear ends of the base 1 are rotatably connected to the walking wheels 7. The bottom left front and rear ends of the base 1 are fixedly connected to the reinforcing seats 8. The left outer wall of the base 1 is fixedly connected to the anti-slip sleeve 9.

Specifically, the device can be easily moved by the walking wheels 7, and the reinforced base 8 can further increase the stability of the device. The control panel 11 can control the operation of the micro motor 392, servo motor 3913, electric slide rail 41, stepper motor 471, electric push rod 53, servo motor 58, robotic arm 591, hydraulic rod 592 and stepper motor 61.

[0036] Working principle: When using this device, the device is first moved to the desired working position by the cooperation between the traveling wheel 7 and the anti-slip sleeve 9. Then, a hole is drilled in the ore body by the drilling mechanism 4. Then, one end of the diamond wire saw 3915 is passed through the drill hole and then wound around the guide wheel 3912 and the wire saw disc 3914 in sequence. Then, the servo motor 3913 is started to drive the wire saw disc 3914 to rotate, thereby completing the cutting work of the ore body. The worm gear 32 and the worm wheel 34 meshing with it will rotate, thereby driving the first rotating shaft 36 to rotate. The second rotating shaft 310 will also rotate through the connecting rod 311, thereby driving the hollow frame 37 to move upward inside the connecting frame 31. The movable rod 3910 inside the hollow rod 399 will also move upward. As the I-beam plate 38 moves, the guide wheel 3912 on the front side also moves, which keeps the diamond wire saw 3915 in a taut state during the cutting process, making it less prone to cutting jerks and thus improving the cutting efficiency of the device. When it is necessary to adjust the cutting angle according to actual usage requirements, the corresponding micro motor 392 is activated. The micro motor 392 drives the threaded rod 393 to rotate, and the movable block 394 on the threaded rod 393 moves accordingly. At this time, the movable shaft 395 rotates, and the movable shaft 397 also rotates through the connecting plate 398. Since the I-beam plate 38 rotates inside the hollow frame 37, it can simultaneously drive the two guide wheels 3912 to adjust the left and right angles to meet different cutting environments. Before drilling, the location to be drilled is determined. Then, the moving base 42 is moved to the designated position via the electric slide rail 41. The drilling assembly 47 on the moving base 42 will move accordingly. At the same time, the stepper motor 61 is started, which can drive the threaded rod 62 to rotate. The moving block 63 will move accordingly. Through the cooperation between the gear shaft 65 and the rack 66, the machine body 2 can move more smoothly on the base 1 until the drill bit 473 contacts the ore body first. Then, the limit rod 46 is unscrewed to release the limit on the support column 45. At this time, the support column 45 will slide inside the hollow column 43. The support columns 45 around the machine can prevent the drill bit 473 from tilting during use. Then, the stepper motor 471 is started to drive the drill bit 473 to rotate, and the drilling work is completed. Through the coordinated operation of drilling and cutting, the mining cycle can be shortened, and the accuracy of drilling can be guaranteed. After the cutting work is completed, the robotic arm 591 drives the hydraulic rod 592 to move towards the marble block until the push plate 593 contacts the marble block. Then, the hydraulic rod 592 is activated to push the marble block forward. At the same time, the servo motor 58 drives the bidirectional lead screw 510 to rotate. The clamping plate 511 on the bidirectional lead screw 510 will move towards the center to limit and clamp the block. When the machine body 2 moves to the left, the block will tilt accordingly. At this time, the hollow plate 56 will tilt along with the torsion spring 57 to limit and clamp blocks of different sizes, so as to prevent them from tipping over during the separation process, thereby maximizing the protection of the integrity of the stone.
