Description

Technical Field

[0001] This invention relates to the field of tunneling equipment technology, and in particular to a multifunctional tunnel / roadway excavation equipment. Background Technology

[0002] In coal mine systems, roadways (hereinafter referred to as rock roadways) and railway, highway, and hydropower systems (hereinafter referred to as rock tunnels) are constructed by excavation in rock mass. Drilling and blasting rock has always been the most commonly used rock breaking method. Other rock breaking methods include full-face mechanical rolling and scraping rock breaking by TBMs (Tunnel Boring Machines, including open-face and shield types), and partial-face cutting rock breaking by high-power cantilever horizontal axis hard rock tunnel boring machines.

[0003] In terms of adaptability to factors such as changes in pitch angle and advance direction of roadways and tunnels (hereinafter referred to as roadways / tunnels) located in rock masses, size of roadway / tunnel cross-section and length, rock hardness, and changes in surrounding rock stability, drill-and-blast rock breaking is significantly superior to TBM. In addition, TBM is large in size and complex in structure, and its cost is relatively much higher. Its installation and removal cycle is long, and its rock breaking energy consumption per unit volume and the cost per meter of project are significantly higher. Therefore, even though TBM has been around for many years, it still cannot completely replace the traditional drill-and-blast rock breaking method.

[0004] The cantilevered horizontal axis high-power hard rock tunnel boring machine (TBM), which has been on the market for over 20 years, has not been widely adopted in tunnel / tunnel excavation due to several issues. These issues include high noise levels from the cutting teeth when cutting hard rock, extremely high dust concentrations that seriously endanger the occupational health of construction workers, and high project costs (mainly due to high wear and tear of the cutting teeth, equipment maintenance and depreciation costs, and financial expenses). Moreover, if the rock hardness exceeds the Protodyakonov hardness coefficient of 7, the construction speed will be significantly reduced. In particular, when the rock hardness exceeds the Protodyakonov hardness coefficient of 9, it is almost impossible to use a hard rock TBM for rock breaking. A few cities have resorted to using high-power cantilevered horizontal axis hard rock TBMs because of limitations that prevent the use of conventional drilling and blasting rock breaking methods and the availability of TBMs. However, the results have been far from ideal.

[0005] It is entirely foreseeable that drilling and blasting rock will remain the irreplaceable rock-breaking method for roadway / tunnel construction for the present and for a considerable period of time to come. However, due to the fact that the span of small-span roadways / tunnels, especially coal mine rock roadways, is mostly less than 6.0m, which does not meet the width required for two machines with different functions to pass each other, it is impossible to use two or even three or more different construction machines to work alternately at the working face, as is the case with general railway tunnel excavation. Therefore, many coal mines currently face at least two prominent problems in rock roadway excavation: First, the level of mechanization is low. Some operations still have to be completed manually by operating outrigger-type rock drilling rigs and single-unit pneumatic anchor drilling rigs, resulting in high labor intensity and low efficiency. Second, the construction speed is low. Even after long-term development, the monthly advance per head is mostly below 80m, rarely exceeding 80m, and even less often reaching 100m or more. However, with continuous high-intensity mining, shallow coal resources are rapidly decreasing, and in recent years, deeper resources have been increasingly mined. This leads to higher methane content in deep coal resources, necessitating pre-mining methane drainage through rock tunnels excavated in adjacent coal seams to significantly reduce the methane content and create the necessary conditions for safe subsequent mining. However, the current monthly advance rate of rock tunnel excavation is insufficient to meet the needs of normal mine production. Therefore, it is essential to develop multi-functional tunnel / roadway excavation equipment with two or more functions to improve the mechanization, construction speed, and efficiency of small-span tunnel / roadway excavation, while reducing the labor intensity of construction workers.

[0006] It should be further explained that the working platform is an indispensable and important device in the tunnel / roadway excavation process. It is common practice to erect temporary, ground-based working platforms on the tunnel / roadway floor for use during anchor bolt support and / or loading of explosives and detonators. However, erecting temporary, ground-based working platforms on the tunnel / roadway floor has at least the following drawbacks: First, the flatness of the tunnel / roadway floor at the construction site is rarely sufficient to meet the requirements for building a working platform. If the working platform is built on an uneven floor, instability will inevitably occur, which may at least affect normal operations, or even cause the platform to tilt. First, leveling the tunnel floor can easily lead to accidents, but it takes time, which reduces work efficiency. Second, ground-mounted work platforms always have outriggers, and to ensure the platform's stability, the outriggers must extend beyond the platform's footrest, taking up a lot of space and affecting normal on-site operations. Third, the workload of disassembling and assembling a work platform with outriggers is much greater than that of a work platform without outriggers. Fourth, adjusting the height of a ground-mounted work platform is purely manual, which is cumbersome and time-consuming, inevitably reducing work efficiency.

[0007] Undoubtedly, a full-time onboard work platform can completely eliminate a series of drawbacks of a temporary ground-based work platform. However, for multi-functional construction equipment with three or more functional components, including rock cuttings loading and transportation and rock drilling, the space is simply not available for setting up a full-time onboard work platform due to the large number of working mechanisms. Therefore, it is necessary to study and solve the technical problem of how to set up a non-ground-based work platform in the above situation. Summary of the Invention

[0008] In view of this, the present invention provides a multifunctional roadway / tunnel excavation construction equipment, which uses a rock cutting and loading mechanism as the foundation for the construction of the working platform, and uses a non-full-time on-board working platform technology that can be quickly disassembled and assembled to eliminate the drawbacks of the ground-based working platform, thereby reducing labor intensity and improving construction efficiency and speed.

[0009] To solve the above-mentioned technical problems, the technical solution of the present invention is: a multi-functional tunnel / roadway excavation construction equipment, comprising: a chassis, a scraper conveyor, and a rock cutting loading mechanism; the chassis includes a frame and tracked walking parts installed on the left and right sides of the frame; the scraper conveyor is installed longitudinally on the frame; the rock cutting loading mechanism includes a rotating body, a first loading arm, a second loading arm, and a bucket that are sequentially hinged to each other; a first telescopic cylinder is provided between the rotating body and the first loading arm; a second telescopic cylinder and a third telescopic cylinder are respectively provided between the second loading arm and the first loading arm and the bucket; the rotating body is rotatably mounted on the chassis; the rotating body and the chassis... A loading and unloading mechanism with a rotary power unit, a rock drilling device, and a working platform device are arranged between the two sides. The working platform device is detachably installed on the bucket or the second loading and unloading arm and is used as a working platform for personnel to work on anchor bolt support and / or to load explosive rock breaking materials into the drilling holes. The rock drilling device is used to anchor bolt support the surrounding rock of the tunnel / slot and to create drilling holes in the rock mass of the working face in front of the chassis. It includes a boom assembly and a rock drilling mechanism. The boom assembly includes a boom. The rear end of the boom is movably installed on the left and right sides of the chassis with its front end swinging in both vertical and horizontal dimensions. The rock drilling mechanism is movably installed on the front end of the boom.

[0010] The work platform device includes work platform I and work platform II. Work platform I includes pedal I and work platform II includes pedal II. Pedal I and pedal II are respectively detachably installed on the left and right sides of the bucket or the second loading arm.

[0011] The work platform device further includes a base, which is detachably connected to the bucket, and first connectors are respectively provided on its left and right sides; both pedal I and pedal II are square frame structures, and second connectors are fixedly connected to the front and rear edges of pedal I and pedal II respectively; a connecting arm is provided between the first connector and the second connector, and the two ends of the connecting arm are respectively inserted into the first connector and the second connector and connected in a detachable manner.

[0012] The first connector has a first socket, the second connector has a second socket, and the connecting arm has multiple arm sockets. The first socket is fixedly connected to the connecting arm by corresponding to the arm socket at the end of the connecting arm and inserting a first pedal anti-reverse pin. The second socket is fixedly connected to the connecting arm by corresponding to different arm sockets and inserting a second pedal anti-reverse pin.

[0013] The base rests against the back plate of the bucket, and limit plates are provided on both sides of the base. The limit plates have limit holes. The side plates on both sides of the bucket have bucket insertion holes. The bucket insertion holes correspond to the limit holes and are inserted into the base anti-reverse pins to achieve a fixed connection between the two.

[0014] Both pedal I and pedal II are equipped with detachable fences that surround the front, back, left, and right sides of pedal I and pedal II.

[0015] The chassis is provided with a boom sliding mechanism that can slide back and forth on both sides. The boom sliding mechanism includes a boom slide rail and a boom slide base. The boom slide rail is arranged longitudinally on the chassis. The boom slide base is slidably or rollingly installed on the boom slide rail. A sliding power device is provided between the chassis and the boom slide base. The rear end of the boom is movably installed on the boom slide base with its front end swinging in both vertical and horizontal dimensions.

[0016] The rock drilling mechanism includes a rock drilling rig, a sliding block, a rock drilling frame, a propulsion mechanism, and a rock drilling slide. The rock drilling rig is fixedly connected to or integrally formed with the sliding block. The sliding block is slidably mounted on the rock drilling frame. The propulsion mechanism is located between the sliding block and the rock drilling frame, driving the sliding block to slide relative to the rock drilling frame. The rock drilling frame is slidably mounted on the rock drilling slide. A rock drilling frame drive cylinder is provided between the rock drilling frame and the rock drilling slide.

[0017] The rear end of the boom is connected to the transition connecting seat via a cross hinge joint. The transition connecting seat is connected to or integrally formed with the boom slide. Two boom swing cylinders are provided between the rear part of the boom and the boom slide. The rear end of the boom swing cylinder is connected to the transition connecting seat via a cross hinge joint, and its front end is hinged to the boom.

[0018] The front end of the boom is connected to the rock drilling slide via connector I, connector II, rotary cylinder I, rotary cylinder II, and rock drilling slide;

[0019] The front end of the boom is connected to the mounting end of the rotary cylinder I. The output end of the rotary cylinder I and the mounting end of the rotary cylinder II are respectively connected to the connecting piece I. The output end of the rotary cylinder II is connected to the connecting piece II. The rock drilling slide is rotatably mounted on the connecting piece II. A rock drilling slide swing cylinder is provided between the rock drilling slide and the connecting piece II.

[0020] The boom slide is further provided with a lifting seat that is slidably connected thereto. A lifting power device is provided between the lifting seat and the boom slide. The transition connecting seat is fixedly connected to or integrally formed with the lifting slide.

[0021] After adopting the above technical solution, the present invention has achieved the following beneficial effects:

[0022] Firstly, regarding multi-functional tunnel / tunnel excavation equipment, especially multi-functional construction equipment with three or more functions suitable for small-span tunnel / tunnel excavation, due to the large number of functional components, there is simply no space available to set up a full-time onboard work platform, and only temporary ground-based work platforms can be built. This application takes a unique technical approach and creatively uses the bucket of the rock cutting loading mechanism, which is indispensable for multi-functional tunnel / tunnel construction equipment, as the basis to configure a non-full-time onboard work platform that can be quickly assembled and disassembled for construction workers. This replaces the temporary ground-based work platform that is placed on the tunnel / tunnel floor, which has a series of drawbacks, and represents a substantial technological breakthrough and progress.

[0023] Secondly, by utilizing the first, second, and third telescopic cylinders of the rock cutting loading mechanism, the height, pitch angle, and forward / backward position of the working platform can be easily adjusted according to operational needs. Furthermore, if the second loading arm is further configured as a rotatable loading arm consisting of an upper arm and a lower arm, the coordinated rotation of the slewing body and the second loading arm can not only allow the left and right working platforms to swing left and right, but also ensure that the distance between the left and right working platforms and the rock wall in front of the working face remains the same.

[0024] Third, the working platform and the base, as well as the base and the bucket, are all fixedly connected by pins with anti-reverse function, which makes disassembly and assembly very convenient.

[0025] Fourth, this application not only sets up two working platforms, left and right, but also adopts an adjustable structure for the connection position between the connecting arm between the working platform and the base and the working platform. This can minimize the size and weight of the working platform, facilitate the adjustment of the working platform's lateral position during operation, and also facilitate the storage and transportation of the working platform.

[0026] Fifth, a boom sliding mechanism that can slide forward and backward is installed on the chassis. Through the longitudinal sliding of the boom slide and the lifting of the lifting seat, the boom can be further increased and the forward and backward movement range of the rock drilling mechanism can be driven. It also enables the rear end of the boom to have a lifting function. This solves the problem of blind spots in the drilling operation caused by installing the rock drilling device on both sides of the equipment chassis, as well as the problem of the rock drilling device hitting the rock wall in front of the working face when the loading mechanism is loading the rock debris at the front of the working face. It also makes it easier for the rock drilling device to create blasting holes and carry out anchor bolt support operations in a larger range without moving the chassis.

[0027] Sixth, the equipment developed in this application lays a technical foundation for further development of equipment with more complex mechanical structures and more functions suitable for small-span tunnel / roadway excavation. Attached Figure Description

[0045] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments to further understand the purpose, solution and effect of the present invention, but it is not intended to limit the scope of protection of the appended claims.

[0046] like Figure 1 As shown, a multi-functional tunnel / tunnel excavation construction equipment includes a chassis 1 comprising a frame and tracked traveling parts mounted on the left and right sides of the frame. The chassis 1 is equipped with a loading shovel 6, a rock cutting mechanism 5, a working platform device 2, a scraper conveyor 7, and a rock drilling device 4. The scraper conveyor 7 is longitudinally mounted on the frame, and the rock drilling device 4 is located on both sides of the chassis 1. In this embodiment, the rock drilling device 4 is mounted on the chassis 1 via a boom sliding mechanism 3.

[0047] The rock debris loading mechanism 5 works in conjunction with the loading shovel 6 to load the rock debris onto the scraper conveyor 7. The scraper conveyor 7 (commonly known as "the first conveyor") is located in the center of the frame and is used to transfer the rock debris to the rear of the chassis.

[0048] The rock drilling device 4 is used to create drilling holes for blasting rock in the working face in front of the chassis 1 and to provide anchor bolt support for the surrounding rock of the tunnel / street.

[0049] The boom sliding mechanism 3 is used to eliminate the problem of blind spots in the operation of the rock drilling device 4 caused by installing the rock drilling device 4 on both sides of the equipment chassis 1, as well as the problem of the rock drilling device hitting the rock wall in front of the working face when the loading mechanism loads the rock debris at the front of the working face. It can also further increase the forward and backward movement range of the rock drilling device 4, so that the rock drilling device 4 can create blasting rock boreholes and carry out anchor bolt support operations in a larger range.

[0050] The working platform device 2 is detachably installed on the bucket 53 or the second loading arm 52, and is used as a working platform for anchor bolt support and / or for loading explosive rock breaking materials into the drilling borehole for drilling blasting.

[0051] The specific structure of the above-mentioned main components is described in detail below.

[0052] Figure 4 The specific structure of the rock slag loading mechanism 5 is shown, combined with Figure 1 The rock slag loading mechanism 5 includes a rotating body 54, a first loading arm 51, a second loading arm 52, and a bucket 53 that are hinged in sequence. The rear end of the first loading arm 51 is hinged to the rotating body 54. The rotating body 54 is rotatably mounted on the chassis 1. The rotating power device 58 of the loading mechanism is located between the rotating body 54 and the chassis 1. A first telescopic cylinder 55 is provided between the rotating body 54 and the first loading arm 51. A second telescopic cylinder 56 and a third telescopic cylinder 57 are respectively provided between the second loading arm 52 and the first loading arm 51 and the bucket 53.

[0053] like Figure 2 and Figure 3 As shown, the work platform device 2 includes work platform I 21 and work platform II 22. Work platform I 21 includes pedal I 213, and work platform II 22 includes pedal II 214. Pedals I 213 and II 214 are detachably mounted on the left and right sides of the bucket 53, respectively. In some cases, pedals I 213 and II 214 can also be mounted on the second loading arm 52.

[0054] Specifically, the work platform device 2 also includes a base 23, which is detachably connected to the bucket 53, and has first connectors 211 on its left and right sides respectively. Both pedal I 213 and pedal II 214 are square frame structures, and second connectors 212 are fixedly connected to the front and rear edges of pedal I 213 and pedal II 214 respectively. A connecting arm 215 is provided between the first connectors 211 and the second connectors 212, with both ends of the connecting arm 215 inserted into the first connectors 211 and the second connectors 212 respectively, and connected in a detachable manner.

[0055] More specifically, the first connector 211 is provided with a first socket, the second connector 212 is provided with a second socket, and the connecting arm 215 is provided with multiple arm sockets. The first socket is fixedly connected by inserting a first pedal anti-reverse pin 216 into the arm socket located at the end of the connecting arm. The second socket is fixedly connected by inserting a second pedal anti-reverse pin 217 into the arm socket located at a different end of the connecting arm 215. Figure 2 This diagram shows the structure of work platform I and work platform II 22 in the closed state. Figure 3 The diagram shows the working platform I and working platform II 22 in the extended state. The aforementioned telescopic sleeve structure minimizes the size and weight of individual working platforms, facilitates length adjustment during operation, and also facilitates storage and transportation. The working platforms and buckets are all connected and secured with pins, allowing for quick and easy assembly and disassembly.

[0056] Limiting plates 231 are provided on both sides of the base 23. Limiting plates 231 have limiting plate insertion holes. The side plates on both sides of the bucket 53 have bucket insertion holes. The bucket insertion holes correspond to the limiting plate insertion holes and are inserted into the base anti-reverse pins 232 to achieve a fixed connection between the two. The base 23 abuts against the back plate of the bucket 53.

[0057] For safety, pedal I 213 and pedal II 214 are equipped with detachable railings 218 on all four sides.

[0058] In this embodiment, based on the bucket of the rock cutting loading mechanism, an indispensable component of multi-functional tunnel / tunnel construction equipment, a non-full-time onboard working platform that can be quickly assembled and disassembled is provided for construction workers. This replaces the temporary ground-based working platform that has a series of drawbacks and is attached to the tunnel / tunnel floor, representing a substantial technological breakthrough and advancement. Using the first telescopic cylinder 55, the second telescopic cylinder 56, and the third telescopic cylinder 57 of the rock cutting loading mechanism 5, the height, pitch angle, and forward / backward position of the working platform can be easily adjusted according to operational needs. Furthermore, if the second loading arm 52 is configured as a rotatable loading arm consisting of an upper arm and a lower arm, the coordinated rotation of the rotating body 54 and the second loading arm 52 not only allows the working platform to swing left and right but also ensures that the distance between the left and right sides of the working platform and the rock wall in front of the working face remains the same.

[0059] In summary, adjusting the position and pitch angle of the work platform is very convenient.

[0060] Figure 5 The specific structure of the boom sliding mechanism 3 is shown, combined with Figure 1 and Figure 6 The chassis 1 is equipped with a boom sliding mechanism 3 that can slide back and forth. The boom sliding mechanism 3 includes a boom slide rail 33 and a boom slide seat 34. The boom slide rail 33 is longitudinally arranged on the boom base 31, and the boom base 31 is fixed to the chassis 1. The boom slide seat 34 is slidably or rollingly mounted on the boom slide rail 33. A sliding power device 32 is provided between the boom base 31 and the boom slide seat 34. The sliding power device 32 is preferably a telescopic cylinder, but it can also be other linear power devices. The rear end of the boom 413 is movably mounted on the lifting seat 35 with its front end swinging in both vertical and horizontal dimensions. The lifting seat 35 is slidably mounted on the boom slide seat 34. A lifting power device (not shown in the figure) is provided between the lifting seat 35 and the boom slide seat 34. The lifting power device is preferably a telescopic cylinder, but it can also be other linear power devices. From the inventive concept, the boom base 31 can be regarded as part of the chassis 1.

[0061] In this example, the sliding power device 132, which is disposed between the chassis 11 and the boom slide 134, generally refers to the power device that drives the boom slide to move relative to the slide rail. It includes both the boom slide being slidably mounted on the slide rail and moving relative to the slide rail, and the boom slide rolling on the slide rail and moving relative to the slide rail.

[0062] Of course, if the lifting seat 35 is not set, the rear end of the boom 413 is mounted on the boom slide 34 in a way that its front end can swing in both vertical and horizontal dimensions (that is, the transition connecting seat 411 is fixedly connected to the boom slide 34). The advantage is that the structure is simplified, but the flexibility of the rock drilling device 4 is reduced and its adaptability to the working environment will be worse.

[0063] Figure 6 The specific structure of the rock drilling device 4 is shown, combined with Figure 1 The rock drilling device 4 includes a boom assembly 41 and a rock drilling mechanism 42 connected together. The boom assembly 41 includes a boom 413 and hydraulic cylinders, connectors, etc. connected to the boom 413. The boom 413 is a telescopic boom with a built-in telescopic hydraulic cylinder. In this embodiment, the rear end of the boom 413 is movably mounted on the lifting seat 35 of the boom sliding mechanism 3 with its front end swinging in both vertical and horizontal dimensions. The longitudinally movable front end of the boom 413 is movably connected to the rock drilling mechanism 42. In this way, the boom 413 can move longitudinally with the boom slide 34 of the boom sliding mechanism and rise and fall with the lifting seat 35. This not only solves the problem of blind spots in the operation of the rock drilling device caused by setting the rock drilling device on both sides of the equipment chassis, but also the problem of the rock drilling device hitting the rock wall in front of the working face when the loading mechanism loads the rock debris at the front of the working face. Furthermore, it can increase the forward and backward movement range of the rock drilling device 4, so that the rock drilling device can create blasting rock boreholes and carry out anchor bolt support operations in a larger range.

[0064] Of course, without the boom sliding mechanism 3, the rear end of the boom 413 can be directly and movably connected to the chassis 1.

[0065] Reference Figure 6 The rear end of the boom 413 is hinged to the transition connecting seat 411 via a cross hinge joint a. The transition connecting seat 411 is fixedly connected to or integrally set with the lifting seat 35. Two boom swing cylinders 412 are provided between the rear of the boom 413 and the chassis. The rear end of the boom swing cylinder 412 is hinged to the transition connecting seat 411 via a cross hinge joint b, and its front end is hinged to the boom 413. By extending and retracting the two boom swing cylinders 412, the boom 413 can be driven to swing its front end in both vertical and horizontal dimensions.

[0066] Reference Figure 6The rock drilling mechanism 42 includes a rock drill 422, a slide 421, a rock drill frame 423, and a propulsion mechanism 425. The rock drill 422 is fixedly connected to or integrally set with the slide 421, and the slide 421 is slidably mounted on the rock drill frame 423. The propulsion mechanism 425 preferably adopts a hydraulic cylinder-wire rope speed-multiplying mechanism or a hydraulic cylinder-chain speed-multiplying mechanism. The propulsion mechanism 425 is set between the slide 421 and the rock drill frame 423 and is used to drive the slide 421 to slide relative to the rock drill frame 423. With the speed-multiplying mechanism, the drilling depth can reach twice the hydraulic cylinder stroke, achieving a larger drilling depth with a smaller hydraulic cylinder stroke (length). The rock drilling mechanism 42 includes a rock drilling slide 424, which is movably connected to the front end of the boom 413. The rock drilling frame 423 is slidably mounted on the rock drilling slide 424. A rock drilling frame drive cylinder 426 is provided between the rock drilling frame 423 and the rock drilling slide 424. The rock drilling frame drive cylinder 426 can drive the rock drilling frame 423 to slide forward relative to the rock drilling slide 424, so that its front end abuts against the working face rock wall or surrounding rock wall, thereby increasing the stability of the rock drilling mechanism 42 during drilling operations.

[0067] In this embodiment, the front end of the boom 413 is connected to the rock drilling slide 424 via connector I 418, connector II 420, rotary cylinder I 417 (shown in the figure as longitudinally arranged), and rotary cylinder II 419 (shown in the figure as vertically arranged).

[0068] Specifically, the front end of boom 413 is connected to the mounting end of rotary cylinder I 417, the output end of rotary cylinder I 417 and the mounting end of rotary cylinder II 419 are respectively connected to connector I 418, and the output end of rotary cylinder II 419 is connected to connector II 420.

[0069] The rock drilling slide 424 is rotatably mounted on the connecting part II 420. A rock drilling slide swing cylinder 427 is provided between the rock drilling slide 424 and the connecting part II 420. The rotation of the rotary cylinder I 417 drives the rotary cylinder II 419 and the rock drilling mechanism 42 connected to the rotary cylinder II 419 to swing around the rotation center of the rotary cylinder I 417; the rotation of the rotary cylinder II 419 drives the rock drilling mechanism 42 to swing around the rotation center of the rotary cylinder II 419; the extension and retraction of the rock drilling slide swing cylinder 427 can adjust the pitch angle of the rock drilling mechanism 42.

[0070] The multi-functional tunnel / tunnel excavation equipment disclosed in this embodiment, based on the specific connection method between the rock drilling mechanism 42 of the rock drilling device 4 and the front end of the boom 413, is particularly suitable for creating blasting rock boreholes in the working face rock mass in front of the chassis and implementing anchor bolt support for the surrounding rock of the tunnel / tunnel.
