Description

Technical Field

[0001] The present invention relates to the field of engineering machinery technology, and specifically, to an integrated rock tunnel high-speed driving equipment and its usage method.

Background Art

[0002] In China, underground coal mining is the mainstream, and tunnel driving is an important prerequisite for coal mining. With the continuous improvement of coal mining technology and equipment level, the tunneling operation is also facing higher requirements. Currently, in China, new tunnels with an annual extension of more than 12,000 kilometers are being excavated, and more than 80% of them are coal tunnels. However, tunnel driving still adopts conventional processes such as drilling, charging, blasting, transportation, and construction. The average driving speed of coal tunnels is less than 200 meters per month, and the number of required workers exceeds 700,000. Due to the slow driving speed, large number of personnel, and low level of intelligence, the coordination between mining and tunneling is in short supply, and the low driving efficiency has become the main factor restricting the safe and efficient coal mining. The cantilever roadheader is the core equipment for tunnel driving, with the ability to adapt to various geological conditions, a high level of mechanization, flexible mobility, and can be used in combination with various subsequent equipment. Currently, at the tunnel driving working face, a complete and efficient driving system has not been formed, and a series of problems such as imbalance in excavation, support, transportation, and bolt construction exist. The cutting ability of the roadheader cannot be fully exerted, the intelligence level of the equipment is not high, the关联性 between systems is not strong, and centralized control cannot be achieved. Therefore, how to achieve the mechanical high-efficiency crushing of ultra-hard rock masses in coal mines has already become an important issue and a difficult point in the high-speed driving of hard rock tunnels.

[0003] In recent years, advanced drilling and exploration technology equipment has seen innovative implementation in three areas: integrated drilling and exploration, high-speed advanced exploration, and integrated exploration technology based on directional drilling, providing valuable insights for tunnel boring operations. The conventional work method of cantilever-type tunnel boring machines + anchor rod drills is being phased out, and equipment models that integrate drilling, support, and transportation are gradually emerging. Series of integrated drilling and exploration machines such as the EBZ160T, EBZ220T, and EBZ260T, produced by companies such as the Taiyuan Research Institute of China Coal Science and Technology Group and Shijiazhuang Coal Mine Machinery Co., are being applied in large and medium-sized coal mines. The drill is installed on the side of the machine body and performs exploration drilling at different angles through a two-stage telescopic cylinder, drilling before construction. The drill is pushed out from one side of the machine body to a designated position and retracts to its original position after drilling is complete, so as not to affect normal drilling. To ensure the proper operation of the tunneling machine, coordinating with temporary support devices allows for effective completion of drilling exploration and support within a certain range of the overall excavation surface, top slab, bottom plate, and side walls. Under conditions permitted by geological requirements, staged, synchronized support is implemented using different equipment to improve excavation efficiency.

[0004] Pulsating hydraulic fracturing (PPR) is an improved rock fracturing method based on conventional hydraulic fracturing techniques and is widely applied in fields such as oil and gas extraction, hard rock mining in coal mines, and underground construction. Conventional hydraulic fracturing involves injecting high-pressure fluid into a borehole, utilizing the rock's properties of being strong in compression and weak in tension to form cracks, thereby reducing the rock's strength and facilitating subsequent mining. However, conventional hydraulic fracturing has problems such as high energy consumption, difficulty in control, and stress concentration in the rock. In particular, under high-hardness rock masses and complex geological conditions, sustained high pressure can cause uneven fracture of the rock, potentially affecting the stability and safety of the drilling process. Therefore, pulsating hydraulic fracturing technology is becoming an increasingly important improvement method. By adopting pulsating hydraulic fracturing, the hard rock mass on the tunnel drilling work surface can be fractured in a directional manner to form plate-like rocks of a certain thickness, and then vibratory cutting can be performed using an alloy roller cutter, thereby improving rock fracturing efficiency. Therefore, tunneling equipment that integrates exploration, support, and cutting enables centralized and visible control within the tunnel, not only shortening the tunneling time compared to conventional methods, but also representing a potential path to more efficient and rapid tunneling due to the higher degree of mechanization, automation, and intelligence of the overall excavation work line.

[0015] This application further provides a method for using the above-mentioned integrated type high-speed rock tunnel drilling equipment. Step 1: Drilling and pulsating hydraulic fracturing When fracturing hard rock with a Protjakonov hardness coefficient f > 15 within a tunnel, first, the position of the drilling equipment is adjusted to the center of the tunnel, and the travel mechanism is used to slide it to the appropriate position on the slide platform. The pump station drives two elevation and oscillating cylinders, extending them to raise the manipulator arm. Then, the pump station controls one left-right oscillating cylinder to shorten and the other left-right oscillating cylinder to extend it, in conjunction with the first and second rotating members, to oscillate the manipulator arm to the planned drilling position. The position of the drilling machine is also adjusted using the first and second slewing motors, and an electric slider drives the drilling machine to slide along the drill guide rail, allowing the self-drilling anchor rod body to enter the rock body and fracture the planned rock. A long, straight borehole is formed in the rock mass. The drilling machine is adjusted to release the hollow joint rod body at the front end, and the drilling machine is retracted. A centering device is fitted to the rear end of the hollow anchor rod body already drilled in the borehole. Another hollow joint rod body is then fitted using a connecting sleeve. The drilling machine is adjusted to connect to the joint rod body, and the drilling machine is driven again to continue drilling in the already formed long, straight borehole. This operation is repeated until the length of the borehole reaches 10m. The drilling machine is then driven out of the borehole, the extended joint rod body is removed, and the manipulator arm and drilling machine are moved to the next planned drilling position. This operation is repeated until multiple long, straight boreholes of 10m in length are drilled. Finally, the manipulator arm is moved out of the work surface, and the travel mechanism is driven back to its initial position, thus completing the drilling operation. Subsequently, a high-pressure sealer is used to seal multiple long, straight deep holes, and a pulsating fracturing system is used to inject pulsating water into the multiple long, straight deep holes. The long, straight deep holes are further enlarged and fractured under the action of pulsating water pressure, and after it is confirmed that the extent of crack expansion has reached the required level, the pulsating water fracturing operation is completed, followed by the removal of the high-pressure sealer. Process 2: Vibration cutting and loading / transportation The process involves adjusting the position of the drilling equipment to the center of the tunnel, driving the telescopic cylinder to adjust the vibrating cutting head, aligning the alloy roller cutter with the enlarged and crushed deep hole, advancing the drilling machine to move the alloy roller cutter into the enlarged and crushed deep hole, simultaneously adjusting the telescopic cylinder so that the alloy roller cutter crushes the rock along the cutting path, then loading the crushed rock fragments through the loading mechanism, transporting the crushed rock fragments through the conveyor belt, and repeating the above process until the cutting depth reaches 1 m. Step 3: Temporary support and anchor support After the completion of the second process, the excavation equipment is adjusted to the appropriate position, and using the hydraulic pump station of the excavation equipment, hydraulic oil is supplied to the support cylinder, folding cylinder, and lifting cylinder of the temporary support mechanism. The lifting cylinder is driven to raise the entire temporary support mechanism, and the folding cylinder is driven to raise the front support frame. Simultaneously, the support cylinder is driven to raise the top protective plate. The support cylinder, folding cylinder, and lifting cylinder are operated in coordination through a multi-way switching valve until the top protective plate and front support frame are adjusted to the desired height and angle, and the operation stops when the predetermined support force is reached. The multi-function drill's travel mechanism is driven, advancing it to the appropriate position on the slide platform, the manipulator arm is driven to advance the drilling machine to the planned anchor support position, and the centering device... to Front section rod body inside the empty anchor rod body fitted into Then, adjust the angle of the drilling machine and connect the section rod body at the rear of the hollow anchor rod body to the drilling machine via the rotating grout adapter. Drive the perforator to advance the bit, and at the same time, use the grout injector to perform grout injection to achieve the effect of simultaneous perforation and grout injection. Stop the grout injection 1 minute after the slurry flows back from the hole opening. After the slurry solidifies, attach a spacer plate to the exposed part of the hollow anchor rod body so as to closely adhere to the rock mass surface, and use a reinforcing bolt to fix the spacer plate so that it compresses the rock mass surface. Repeat the above operations until all the work at the planned position of the anchor support is completed. For the grout injection by the grout injector, adopt pure cement paste or 1:1 mortar, control the particle size of the sand in the mortar to be ≤ 1.0 mm, and control the water-cement ratio to be 0.4 - 0.5. Step 4: The cycle of excavation and support work until the tunnel penetrates When the above three steps are completed, it means that 1 m of tunnel excavation is completed. The two steps of vibration cutting, loading and transportation, and temporary support and anchor support are carried out in the first step. at Multiple 10 m deep holes Milling the formed rock mass Repeat until completion, that is, until one stage of tunnel excavation is completed. The three steps of perforation - pulsating hydraulic fracturing - vibration cutting and loading and transportation - temporary support and anchor support are repeated until the tunnel excavation is completed.

Advantages of the Invention

[0016] Compared with the prior art, the beneficial technical effects of the present invention by adopting the above technical scheme are as follows.

[0017] 1. This application integrates drilling, exploration, pulsating crushing, vibration cutting, and support operations into a single piece of equipment. With a multi-functional drill, deep-hole drilling, exploration, grout injection, and support can be completed on one side of the tunneling machine, reducing the coordination time between processes. The temporary support device is located above the vibration cutting section and supports the rock mass in the cutting area in real-time through the top protection plate and the front support frame, avoiding the risk of rockfall caused by delayed support in conventional tunnel excavation. This application enhances the continuity of the entire tunnel excavation operation, reduces the frequency of equipment movement and waste of time, realizes mechanized and automated operations throughout the processes of drilling, exploration, cutting, and support, and is suitable for excavation scenarios with high safety and efficiency requirements in coal mines and other underground projects.

[0018] 2. The pulsating hydraulic crushing system performs directional crushing on the rock mass inside the drill hole with pulsating water flow, causing the rock mass to gradually form a crack network under high-frequency hydraulic impact. This process fully utilizes the characteristics of the rock being strong in compression and weak in tension, effectively reducing the rock mass strength and forming a bedding structure favorable for cutting. The periodic impact design of pulsating crushing not only effectively avoids the destruction of rock mass stability caused by continuous high pressure but also further expands the cracks and conditions subsequent vibration cutting. Compared with conventional hydraulic crushing methods, pulsating hydraulic crushing has the advantages of energy conservation and strong controllability, has a wider adaptability, and can be applied to the excavation of ultra-hard rock tunnels and tunnels under complex geological conditions.

[0019] 3. The vibration cutting head in this application adopts a combination of alloy roller cutters and eccentric block shafts, enabling high-frequency vibration cutting and allowing the cutting head to perform precision cutting on rock masses at different depths. This design eccentrically vibrates the roller cutter by the rotation excitation of the eccentric block shaft. This technology reduces the resistance during hard rock cutting, makes the crushing process more efficient and stable. This improvement reduces the load and wear of the equipment, extends the equipment life, significantly improves the hard rock excavation efficiency, and can be applied to the excavation operation of hard rock tunnels.

[0025] As shown in Figure 1, the integrated rock tunnel high-speed drilling equipment comprises a crawler-type main frame 1 as a support platform for the overall structure, a vibrating cutting unit 2 installed on the crawler-type main frame 1 and including a vibrating cutting head 2-1 and an extendable section 2-4, which cuts the rock mass by the extension and retraction of the extendable section 2-4 and the vibration of the vibrating cutting head 2-1, a multi-functional drill 3 installed on one side of the crawler-type main frame 1 and used for drilling into the rock mass and attaching anchor rods, and a pulsating crushing system connected to the vibrating cutting unit 2 and installed behind the extendable section 2-4, which generates hydraulic pulsations to crush the rock mass and improve cutting efficiency. The system includes a TEMB 8, a temporary support mechanism 4 installed in front of the crawler-type main frame 1 and used to provide temporary support during the excavation process, a loading mechanism 5 installed below the vibrating cutting section 2 and including a scraper plate 5-2 and a star wheel transport device installed on the scraper plate 5-2, used to collect and load the cut coal and rock, a conveyor belt 6 installed behind the loading mechanism 5 and connected to the loading mechanism 5 and used to transport the coal and rock to the rear of the excavation equipment, and a rear support section 7 installed at the rear of the crawler-type main frame 1 and used to stabilize the position of the excavation equipment during the work process.

[0026] Furthermore, as shown in Figure 2, the vibrating cutting unit 2 is rotatably connected to the front end of the telescopic unit 2-4 via a connecting component. Telescopic cylinders 2-3 are provided above and below the pulsating crushing system 8, and these telescopic cylinders 2-3 are rotatable around their axes. The output ends of the telescopic cylinders 2-3 are rotatably connected to hinge supports 2-2 installed above and below the vibrating cutting unit 2. By independently adjusting the extension or retraction state of these two telescopic cylinders 2-3, the present invention can precisely control the vertical oscillation angle of the vibrating cutting head 2-1. Specifically, when the output end of the upper telescopic cylinder 2-3 is extended and the output end of the lower telescopic cylinder 2-3 is retracted, the vibrating cutting head 2-1 oscillates downward accordingly. Conversely, when the output end of the upper telescopic cylinder 2-3 is retracted and the output end of the lower telescopic cylinder 2-3 is extended, the vibrating cutting head 2-1 oscillates upward. This allows the drilling equipment to adapt to rock formations of varying hardness and angles, improving the flexibility and adaptability of drilling operations.

[0027] Specifically, as shown in Figure 3, the vibratory cutting head 2-1 includes an alloy roller cutter 2-1-1, a front end cover 2-1-2, a front housing 2-1-3, a front sleeve 2-1-5, a rear sleeve 2-1-6, and a rear housing 2-1-7. The alloy roller cutter 2-1-1 is bolted to the front end of the front end cover 2-1-2 and forms the main component of the cutting operation. The rear sleeve 2-1-6 is bolted to the front end of the rear housing 2-1-7 and extends into the interior of the rear housing 2-1-7. Inside the rear sleeve 2-1-6, an eccentric block shaft 2-1-9 is rotatably mounted via two deep groove ball bearings 2-1-8. An eccentric block shaft end cover 2-1-10 is further provided at the front of the front deep groove ball bearing 2-1-8, and a shaft sleeve 2-1-11 for fitting the eccentric block shaft 2-1-9 is provided at the front of the rear deep groove ball bearing 2-1-8. An offset shaft motor 2-1-13 is also mounted at the rear of the rear deep groove ball bearing 2-1-8 via a motor sleeve 2-1-14 and a bearing sleeve 2-1-15, and the output end of the offset shaft motor 2-1-13 is connected to the eccentric block shaft 2-1-9. The front sleeve 2-1-5 is attached to the front end of the rear sleeve 2-1-6 by bolts.

The eccentric block shaft 2-1-9 and the offset shaft motor 2-1-13 are connected by splines, and the axial eccentricity angle of the eccentric block shaft 2-1-9 is 4-5°. The vibratory cutting head 2-1 of this application not only integrates core components such as the alloy roller cutter 2-1-1, the front end cover 2-1-2, the front housing 2-1-3, the front sleeve 2-1-5, the rear sleeve 2-1-6, and the rear housing 2-1-7, but also incorporates multiple optimization characteristics in its design. The alloy roller cutter 2-1-1, as the main component of the cutting operation, employs a high-performance wear-resistant alloy material and is plated with a cemented carbide layer on its surface to enhance its durability and cutting efficiency. Furthermore, smooth rotation is achieved between the front end cover 2-1-2 and the front sleeve 2-1-5 by a cylindrical roller bearing 2-1-4, and the addition of a retaining ring 2-1-12 not only ensures rotational stability but also effectively distributes the large dynamic load generated during cutting, protecting the internal structure from damage. The eccentric block shaft 2-1-9, mounted inside the rear sleeve 2-1-6, is designed with an eccentric angle of 4-5°, and its spline connection to the offset shaft motor 2-1-13 allows for periodic vibration excitation when the offset shaft motor 2-1-13 is driven. This design not only increases cutting efficiency but also effectively reduces cutting resistance and energy consumption. The eccentric block shaft 2-1-9 is supported at both ends by two deep groove ball bearings 2-1-8, with the front end fixed by an eccentric block shaft end cover 2-1-10 and the rear end fitted by a shaft sleeve 2-1-11 and connected to the output terminal of the offset shaft motor 2-1-13, ensuring transmission stability and reliability. The entire vibratory cutting head 2-1 has a compact structure, and the coordination between each part is precise, not only guaranteeing efficient cutting work but also making maintenance and inspection easy, making it an indispensable high-efficiency tool in construction fields such as mining and tunneling.

The pump station 3-14 provides a stable and reliable hydraulic power source to these cylinders, ensuring that the manipulator arm 3-5 can flexibly and accurately complete various movements.

[0032] In one specific embodiment disclosed herein, as shown in Figure 6, the self-perforating anchor rod body 3-13 includes a hollow anchor rod body 3-13-1, a bit 3-13-2, a connecting sleeve 3-13-3, and a centering device 3-13-4. The hollow anchor rod body 3-13-1 is constructed by joining two segment rod bodies with a connecting sleeve 3-13-3. The bit 3-13-2 is installed at the front end of the hollow anchor rod body 3-13-1, and the end of the bit 3-13-2 has a hollow disc-shaped structure with pores distributed in the circumferential direction. The centering device 3-13-4 is installed on the front segment rod body of the hollow anchor rod body 3-13-1. A spacer plate 3-13-5 for pressing against a rock wall is fitted to the rear segment rod body of the hollow anchor rod body 3-13-1, and a reinforcing bolt 3-13-6 is provided on the spacer plate 3-13-5. A grout injection machine 3-16 is further connected to the rear section of the hollow anchor rod body 3-13-1 via a rotating grout adapter 3-11 and a grout injection pipe. Reinforcing bolts 3-13-6 and spacer plates 3-13-5 are used in combination. The reinforcing bolts 3-13-6 first transmit the anchoring force of the hollow anchor rod body 3-13-1 to the spacer plates 3-13-5, which then apply that anchoring force to the surrounding rock mass, transmitting stress, improving the load-bearing capacity at the ends, and enhancing the anchoring effect of the self-drilling anchor rod. The centering device 3-13-4 ensures that the rod body is always at the center of the drilling during the construction process of the self-drilling anchor rod, thereby ensuring that the slurry has a uniform thickness around the rod body and further enhancing the anchoring effect.

[0033] In one specific embodiment disclosed herein, as shown in Figure 7, the pulsating crushing system 8 includes a pulsating crushing casing 8-1. A piston 8-2 is movably provided inside the pulsating crushing casing 8-1, which divides the lumen of the pulsating crushing casing 8-1 into an oil chamber 8-3 and a water chamber 8-4. The oil inlet of the oil chamber 8-3 is connected to the hydraulic system of the drilling equipment. The telescopic section 2-4 is movable back and forth inside the water chamber 8-4. The water intake port of the water chamber 8-4 is connected to a low-pressure water pump 8-5 via a water intake channel, and a pilot-operated check valve 8-6 is provided in the water intake channel. The water discharge port of the water chamber 8-4 is further connected to a hollow anchor rod body 3-13-1 via a water discharge channel. In this system, the water and oil create pressure changes due to the movement of the piston 8-2, thereby generating hydraulic pulsations. Specifically, the hydraulic system of the drilling equipment lubricates and pressurizes the oil chamber 8-3, forming a high-pressure oil flow that moves the piston 8-2 inside the oil chamber 8-3 toward the water chamber 8-4. The low-pressure water pump 8-5 supplies water pressure to the water chamber 8-4 inside the equipment via a pilot-operated check valve 8-6 and a water intake, and the oil chamber 8-3 and the water chamber 8-4 are separated by the piston 8-2. As the piston 8-2 moves, the water in the water chamber 8-4 flows at a constant pressure toward the discharge port connected to the hollow anchor rod body 3-13-1, and at the same time, the vibrating cutting head 2-1 and the telescopic section 2-4 extend and retract under the water pressure of the water chamber 8-4 by the drive of the telescopic cylinder 2-3, sharing the water pressure. When the pulsating pressure reaches a certain value, the pilot-operated check valve 8-6 controls the direction of the fluid flow, ejecting water from the discharge port, which then acts on the crack region via the high-pressure sealer 9. After the water flow drills, pulsating water transmitted from the pulsating fracturing system acts on the rock mass, creating impact forces and inducing cracks within the rock. By periodically discharging pulsating water, a crack network is created that expands within the rock mass, enabling hydraulic fracturing of the rock. Because this process is repeated and cyclical, the equipment can continuously generate pulsating water flow, thereby continuously applying high-frequency impacts to the rock mass.

[0034] In one specific embodiment disclosed herein, as shown in Figure 8, the temporary support mechanism 4 includes a top protective plate 4-1 and a front support frame 4-2. The bottom of the front support frame 4-2 is rotatably connected to a pulsating crushing casing 8-1 via two support seats 4-5. Support cylinders 4-3 are rotatably provided on both sides of the pulsating crushing casing 8-1, and a lifting cylinder 4-6 is further rotatably provided above the pulsating crushing casing 8-1. The output ends of both the support cylinders 4-3 and the lifting cylinders 4-6 are rotatably connected to the front support frame 4-2. The top protective plate 4-1 is rotatably installed above the front support frame 4-2. A folding cylinder 4-4 is further rotatably provided at the front bottom of the top protective plate 4-1, and the output end of the folding cylinder 4-4 is rotatably connected to the front of the front support frame 4-2. The temporary support mechanism 4 is powered by the hydraulic system of the excavation equipment and employs hydraulic oil drive. During operation, the support cylinder 4-3 and the lifting cylinder 4-6 extend to raise the front support frame 4-2 to a predetermined height, after which they stop moving. The folding cylinder 4-4 extends to support the top protective plate 4-1 and press it tightly against the upper rock face. During retrieval, the folding cylinder 4-4 first shortens to store the top protective plate 4-1, and then the support cylinder 4-3 and the lifting cylinder 4-6 shorten to store the front support frame 4-2. The entire temporary support mechanism has high adaptability to the main body of the excavation equipment and high flexibility in its own operating mechanism.

[0035] In one specific embodiment disclosed herein, as shown in Figure 9, the star wheel transport device includes two sets of drive motors 5-3 mounted on a scraper plate 5-2. A left star wheel 5-1 and a right star wheel 5-4 are provided at the output ends of the two sets of drive motors 5-3, respectively. A passage for transporting crushed stone is formed between the left star wheel 5-1 and the right star wheel 5-4, and the conveyor belt 6 is installed in this passage. The function of the star wheel transport device is to collect crushed and fallen coal and rocks, load them onto the conveyor belt 6, and transport them to the rear of the crawler. Specifically, the scraper plate 5-2 scrapes the crushed and fallen rocks, and the left star wheel 5-1 and the right star wheel 5-4 rotate in opposite directions by the drive motors 5-3, transporting the scraped crushed and fallen rocks onto the conveyor belt in real time.

[0036] In one specific embodiment disclosed in the present invention, the rear support section 7 is rotatably installed at the rear of the crawler-type main frame 1 via a rear support cylinder, and some stabilizing supports are provided below the rear support section 7. Both the rear support section 7 and the rear support cylinder are rotatably installed at the rear of the crawler-type main frame 1, and the output end of the rear support cylinder is rotatably connected to the rear support section 7. As a result, the extension and retraction action of the support cylinder allows the rear support section 7 to rotate to the ground, thereby achieving stable support.

[0037] This invention also provides a method for using integrated rock tunneling high-speed drilling equipment, which includes the following steps.

[0038] Step 1: Drilling and pulsating hydraulic fracturing

[0039] When fracturing hard rock with a Protjakonov hardness coefficient f > 15 in a tunnel, first, the position of the drilling equipment is adjusted to the center of the tunnel. Using the travel mechanism 3-2, it is slid to the appropriate position on the slide platform 3-1. The pump station 3-14 drives two elevation and oscillating cylinders 3-10, extending them to lift the manipulator arm 3-5. Subsequently, the pump station 3-14 controls one left-right oscillating cylinder 3-9 to shorten and the other left-right oscillating cylinder 3-9 to move the manipulator arm 3-5 to the planned drilling position in conjunction with the first rotating member 3-3 and the second rotating member 3-4. Furthermore, the position of the drilling machine 3-8 is adjusted using the first slewing motor 3-18 and the second slewing motor 3-15, and an electric slider drives the drilling machine 3-8 to slide along the drill guide rail 3-7, causing the self-drilling anchor rod body 3-13 to enter the rock body and form a long, straight deep hole in the rock body to be fractured. The drilling machine 3-8 is adjusted to release the hollow section rod body at the front end and the drilling machine 3-8 is retracted. The centering device 3-13-4 is fitted to the rear end of the hollow anchor rod body 3-13-1 that has already been drilled into the deep hole, and another hollow section rod body is fitted using the connecting sleeve 3-13-3. The drilling machine 3-8 is adjusted to connect to the section rod body, and the drilling machine 3-8 is driven again to continue drilling in the long, straight deep hole that has already been formed. The above operation is repeated until the length of the deep hole reaches 10 m. The drilling machine 3-8 is driven out of the deep hole, and the extended joint rod body is removed. The manipulator arm 3-5 and the drilling machine 3-8 are moved to the next planned drilling location, and the above operation is repeated until multiple long, straight deep holes of 10m in length are drilled. Finally, the manipulator arm 3-5 is moved out of the work surface, and the travel mechanism 3-2 is driven back to its initial position. The drilling operation is then completed.

[0040] Subsequently, the multiple long, straight deep holes are sealed using a high-pressure sealer 9. Pulsating water is injected into the multiple long, straight deep holes using a pulsating fracturing system 8. The long, straight deep holes are further enlarged and fractured under the action of pulsating water pressure. After it is confirmed that the extent of crack enlargement has reached the required level, the pulsating water fracturing operation is completed, and then the high-pressure sealer 9 is removed (see Figure 10).

[0041] Process 2: Vibration cutting and loading / transportation

[0042] The position of the drilling equipment is adjusted to the center of the tunnel. The telescopic cylinders 2-3 are driven to adjust the vibrating cutting head 2-1, aligning the alloy roller cutter 2-1-1 with the enlarged and fractured borehole. The drilling machine is advanced to move the alloy roller cutter 2-1-1 into the enlarged and fractured borehole. Simultaneously, the telescopic cylinders 2-3 are adjusted so that the alloy roller cutter 2-1-1 fractures the rock along the cutting path. Subsequently, the fractured rock fragments are loaded through the loading mechanism 5 and transported via the conveyor belt 6. The above process is repeated until the cutting depth reaches 1 m.

[0043] Step 3: Temporary support and anchor support

[0044] After the completion of the second process, the excavation equipment is adjusted and positioned appropriately. Using the hydraulic pump station of the excavation equipment, hydraulic oil is supplied to the support cylinder 4-3, folding cylinder 4-4, and lifting cylinder 4-6 of the temporary support mechanism 4. The lifting cylinder 4-6 is driven to lift the entire temporary support mechanism 4. The folding cylinder 4-4 is also driven to raise the front support frame 4-2. Simultaneously, the support cylinder 4-3 is driven to raise the top protective plate 4-1. Through a multi-way switching valve, the support cylinder 4-3, folding cylinder 4-4, and lifting cylinder 4-6 are operated in coordination until the top protective plate 4-1 and the front support frame 4-2 are adjusted to the desired height and angle, and stop when a predetermined support force is reached.

[0045] The travel mechanism 3-2 of the multi-function drill 3 is driven to advance it to the appropriate position on the slide platform 3-1. The manipulator arm 3-5 is driven to advance the drilling machine 3-8 to the planned anchor support position. Centering device 3-13-4 to Front section rod body of empty anchor rod body 3-13-1 fitted into Adjust the angle of the drilling machine 3-8 and connect the rear section rod body of the hollow anchor rod body 3-13-1 to the drilling machine 3-8 via the rotating grout adapter 3-11.

[0046] The drilling machine 3-8 is driven to advance the bit 3-13-2, and at the same time, grout injection is performed using the grout injection machine 3-16, achieving the effect of simultaneous drilling and grout injection. Grout injection is stopped 1 minute after slurry flows back out of the hole opening. After the slurry has solidified, the spacer plate 3-13-5 is attached to the exposed portion of the hollow anchor rod body 3-13-1 so that it is in close contact with the rock surface, and the spacer plate 3-13-5 is fixed using reinforcing bolts 3-13-6 so that it is compressed against the rock surface. The above operation is repeated until all work at the planned anchor support location is completed. For grout injection using the grout injection machine 3-16, pure cement paste or 1:1 mortar is used. The grain size of the sand in the mortar is ≤1.0 mm, and the water-cement ratio is controlled to 0.4~0.5.

[0047] Phase 4: The cycle of excavation and support work until the tunnel is completed.

[0048] Once the above three steps are completed, the excavation of a 1-meter tunnel will be complete. The two steps of vibratory cutting and loading / transportation, and temporary support and anchor support are combined into the first step. at Multiple 10m deep boreholes Milling the formed rock mass The process is repeated until completion, that is, until one stage of tunnel excavation is finished. The three processes of drilling, pulsating hydraulic fracturing, vibratory cutting and loading / transportation, and temporary support and anchor support are repeated until tunnel excavation is complete.

The travel mechanism (3-2) of the multi-function drill (3) is driven to advance it to the appropriate position on the slide platform (3-1), the manipulator arm (3-5) is driven to advance the drilling machine (3-8) to the planned anchor support position, the centering device (3-13-4) is fitted into the front section rod body in the hollow anchor rod body (3-13-1), the angle of the drilling machine (3-8) is adjusted, and the rear section rod body of the hollow anchor rod body (3-13-1) is connected to the drilling machine (3-8) via the rotary grout adapter (3-11), The drilling machine (3-8) is driven to advance the bit (3-13-2), and at the same time, grout injection is performed using the grout injection machine (3-16), achieving the effect of simultaneous drilling and grout injection. One minute after slurry flows back out of the hole, grout injection is stopped. After the slurry has solidified, a spacer plate (3-13-5) is attached to the exposed portion of the hollow anchor rod body (3-13-1) so as to be in close contact with the rock surface, and the spacer plate (3-13-5) is fixed using reinforcing bolts (3-13-6) so as to be compressed against the rock surface. The above operation is repeated until all work at the planned anchor support location is completed. For grout injection using the grout injection machine (3-16), pure cement paste or 1:1 mortar is used, the particle size of the sand in the mortar is ≤1.0 mm, and the water-cement ratio is controlled to 0.4 to 0.

5. Phase 4: The cycle of excavation and support work until the tunnel is completed. A method for using the integrated rock tunnel high-speed drilling equipment according to claim 4, characterized in that, upon completion of the above three steps, the excavation of a 1m tunnel is completed, and the two steps of vibratory cutting and loading / transportation, and temporary support and anchor support are repeated until milling of the rock body in which multiple 10m deep holes have been formed in the first step is completed, that is, until one stage of tunnel drilling is completed, and the three steps of drilling - pulsating hydraulic fracturing - vibratory cutting and loading / transportation - temporary support and anchor support are repeated until tunnel drilling is completed.
