Description

The invention relates to a method for mining of rock material underground to form a preparation or mining route by means of a full-cutting machine with a rotating driven cutting head whose bore diameter dictates the diameter of the preparation or mining route, according to the preamble of claim 1.

The invention further relates to a full-cutting machine according to the preamble of claim 8.

Full cutting machines for mining of rock material underground to form a training and device line have long been known. Such full-cut machines are complex propulsion systems, which have a cutting head, a bracing and propulsion device and an expansion device and numerous other facilities, such as conveyor belts or transport screws for the removal of the dissolved rock material and corresponding utilities. The rotary driven cutting head works in full section from the rock material, so that a high speed of extraction and efficient track construction can be achieved. Such full-cut machines have a considerable total length of several 10 meters to over 100 meters.

The assembly and disassembly of such a full-line machine is associated with a considerable amount of work and time and can take up to several weeks. Such full-cut machines are therefore usually used to build longer distances, which are substantially rectilinear.

From the generic JP 2002 106 289 A It is known to transport a trimming machine and a plurality of trailers for loading rock material on trolleys, each having a rotatable platform. The full-scale machine is moved with a trolley and turned into a quarry. With progressive degradation, the trailers are tracked to pick up the rock.

The US 5,634,692 discloses a tunnel boring assembly including a main tunnel boring machine and an auxiliary tunnel boring machine. The auxiliary tunnel boring machine is pivotally mounted in the main tunnel boring machine, whereby transverse branches branching from a main line can be drilled.

The invention has for its object to provide a method for mining of rock material underground to form a preparation or mining line and a full-cut machine, which are particularly efficient and flexible.

According to the invention, the object is achieved, on the one hand, by a method having the features of claim 1 and, on the other hand, by a half-cut machine having the features of claim 8. Preferred embodiments of the invention are specified in the respective dependent claims.

The method according to the invention is characterized in that by means of the full-cut machine in a first advancing direction a first fitting or dismantling corner is started and formed starting from a first main line to a second main line, which runs at a distance along the first main line, that the full-cut machine into the second main line is implemented and that starting from the second main line by means of the full-cut machine in a second drive direction, which is the first drive direction substantially opposite, to the first main line a second set-up or dismantling run up and formed.

A basic idea of the method according to the invention can be seen to provide a full-cut machine as a manoeuvrable propulsion device, so that a full-line cutting machine can be implemented and turned over quickly and with limited effort in the limited space underground. The method can be used in particular in mining or in creating smaller secondary lines in tunneling, which extends transversely between two main lines, which may also be tunnels or tunnels. The method according to the invention can also be used to create only one transverse section.

It can be used according to the invention, an efficient working full-cut machine for a transverse route even with smaller distances or tunnels and especially in mines for mining deposits, which previously had to be driven up with other propulsion equipment. In principle, the full-cut machine can be a compact unit.

One aspect of the invention is that the full-cut machine decomposes during conversion into at least two longitudinal modules, which are turned at least two longitudinal modules and assembled again in the opposite direction of advance. The full-cut machine is constructed in a modular manner according to the invention, wherein the individual longitudinal modules can be easily separated from each other and reassembled. The longitudinal modules, which represent longitudinal sections of the elongate full-cut machine, have a length of a few meters, preferably 2 to 6 meters, in particular 3 to 5 meters. The longitudinal modules can thus easily be dismantled, moved and handled underground. In this case, the longitudinal modules are preferably reassembled in the reverse propulsion direction, so that therefore a turning of the longitudinal modules has taken place by about 180 °. The preparation or mining lines and the transverse lines in tunneling can be approximately parallel or at an angle to each other. In certain cases it is also possible to cross routes.

A further advantageous embodiment of the invention can be seen in the fact that between the two main lines more than two preparation or dismantling lines are formed by repeated implementation of the full-cut machine. In particular, a plurality of furnishing or disassembly lines may extend in a ladder-like or meandering manner between the two main sections. This is particularly advantageous in mining mining deposits, which are laterally encompassed by two or more main lines. For example, the main lines may have traveled as conventional equipment and device lines. This can also be done by a full cutting machine or by other mining equipment. Basically, a cross-section of the main lines is required to be larger than that of the assembly or dismantling lines formed by the full-cut machine. This allows an improved handling and maneuvering of the individual longitudinal modules when converting the full-cut machine.

In this case, a preferred embodiment of the invention is that at the beginning of a fitting or dismantling a starting distance is ascended, which is designed to receive the full-cut machine. In this case, before the start of the preparation of the preparation or mining route, a take-off route in the transition region between the main line and the to be formed or Construction route created. In this starting line, which preferably has a larger cross-section than the fitting or dismantling section and preferably a smaller cross-section than the main line, the longitudinal modules are reassembled to form the full-cut machine with corresponding advancing direction.

In particular, it is advantageous that the starting distance is formed by a separate propulsion device. Thus, the starting line can already be worked out of the rock, before the full-cut machine ascends the preparation or mining lines. The propulsion device can basically be a machine system known from mining.

According to a variant of the invention, a particularly stable and safe assembly or dismantling route is achieved by providing an expansion unit on the full-cut machine, by means of which the mountain is stabilized in the surrounding annular space of the set-up or dismantling path. Depending on requirements, it is possible for the expansion unit to introduce all types of construction used in mining and tunneling on the route wall. It is particularly advantageous that boring anchors are introduced into the wall of the formed preparation or dismantling section in an approximately radial direction by the expansion unit.

According to a further preferred embodiment of the invention, it is advantageous that rock material excavated by the cutting head is conveyed to a rear end of the full-cut machine by means of a discharge device. In this case, the discharge device may be a conveyor belt, a screw conveyor, a conveyor trough or other transport medium for rock material. Overall, the discharge device can also be formed of a plurality of conveying elements.

The discharge device extends at least the length of the full-cut machine, which can be up to 10 m and more long.

In this case, according to a further advantageous embodiment variant, it is preferred that the discharged rock material be taken up by a conveyor vehicle and transported out of the preparation or dismantling line. In principle, a receiving space for receiving the processed rock material can be provided in the full-cut machine. The rock material can from this intermediate storage or transported directly from the cutting head to the rear end of the full-cut machine. About a transfer device, the crushed rock material can be transferred to a dump truck or a loader.

The full-line cutting machine according to the invention is characterized in that it is constructed from at least two longitudinal modules which are detachably connected to each other. The longitudinal modules form longitudinal sections of the full-cut machine. These are easily releasably connected to each other via quick-release connections and coupling elements of the respective power lines. The individual longitudinal modules are formed by their length and their respective weight so that they can be picked up and transported underground by a transport and handling vehicle. The longitudinal modules preferably have a length between 1.5 to 4 m and a diameter between 1.5 m and 5 m.

According to a preferred embodiment of the full-line cutting machine according to the invention, it is provided that a first longitudinal module with a cutting head, a second longitudinal module with a bracing and propulsion unit and a third longitudinal module with a bracing unit are provided. The cutting head has a rotating head plate on which, in a known manner, roller-shaped or roller-shaped removal tools or roller bits for removing the rock material are provided at the working face. The cutting head is driven in rotation about a rotation axis, which simultaneously forms a longitudinal axis of the full-cut machine. The cutting head also includes the drive means for rotationally driving the head plate with the removal tools.

Subsequently, as a second separable longitudinal module, the bracing and propulsion unit is arranged, which in particular has one or more hydraulic cylinders. The hydraulic cylinders are arranged in the longitudinal direction and can have a stroke of up to 1 m and more. Subsequently, a third divisible longitudinal module is provided, which is designed as a clamping unit. The clamping unit has radially exposeable clamping elements, with which the full-cutting machine can be braced against the surrounding stretched wall and thus fixed. This allows, during operation, a corresponding driving force to apply to the cutting head and support this propulsive force against the rear Längsmodulwandabstütz. The clamping elements are preferably moved radially in and out via hydraulic adjusting elements. For the corresponding power lines, in particular the electrical power lines, the data lines and the hydraulic lines are provided at the separation points, which extend substantially transversely and preferably at right angles to the longitudinal axis, line connector for a quick release and connecting the lines. Further, mechanical coupling elements, such as bolts or screw connections, are arranged for detachable connection of the longitudinal modules at the separation points.

In principle, further and different longitudinal modules can be provided on the full-cut machine. It is preferred according to a development of the invention that a longitudinal module with an expansion unit and / or a trailer unit with supply and disposal facilities are provided. By means of the expansion unit, it is possible to stabilize and, in particular, support the wall of the assembly or dismantling line formed. About a Nachläufereinheit, which is firmly connected to the preceding longitudinal modules or attached thereto hinged, the supply and disposal facilities can be carried. In particular, the various drive units, such. B. hydraulic pumps, be arranged here. Also suitable means for conveying the rock material and also for the ventilation of the to be traveled or dismantling line or units for lining the track, e.g. be integrated by shotcrete in the tracking unit.

In principle, the longitudinal modules can have a different outer shape. A particularly efficient shaping and space utilization is achieved according to a development of the invention in that the longitudinal modules have an approximately circular cross section, which corresponds approximately to the bore diameter of the cutting head. The longitudinal modules are designed as drum-shaped longitudinal sections of the full-cut machine. As a result, an efficient use of space and a compact form can be achieved. Preferably, the full-line machine is accessible to operating personnel, with several operator stations being provided.

According to a further embodiment, it is preferred that a receiving area for removed rock material and a conveyor for the ablated Rock material are provided. In the receiving area, rock material removed by the cutting head can be temporarily stored in the full-surface cutting machine. By means of suitable conveying devices, the rock material can be conveyed from the cutting head to the receiving area and from the receiving area to the rear end of the full-line cutting machine. At the rear end of the full-cut machine, a transfer device is provided with which the rock material is transferred for further removal. In particular, the rock material can be absorbed by a loader or a dump truck. But it can also be provided a trackable conveyor at the end of the full-cut machine.

A further advantageous embodiment of the invention is that the expansion unit has at least one radially directed carriage, with which anchor can be introduced into the wall of the fitting or removal route. The rock anchors enable a reliable stabilization of the surrounding track wall. The anchor holes are thereby drilled in the route wall approximately radially and the anchor connected to the mountains supporting .. The expansion unit has corresponding drill guides, which are radially directed and adjustable along the circumference of the route wall. The individual anchors can be temporarily stored in a receiving area in the bottom of the expansion or the trailer unit. About a handling unit or an operator, the individual anchor rods or anchor bolts can be inserted into the carriage and introduced with a corresponding drill drive radially into the route wall.

According to the schematic representation of Fig. 1 First, a first main line 3 and a second main line 4 are formed at a distance from each other, wherein an intermediate region is enclosed. The two main lines 3, 4 can already be produced with a full-cut machine or with another removal device. The distance between the two main lines 3, 4 can be several meters to several 100 meters. Other sizes are not excluded from the invention. The two main lines 3, 4 preferably run parallel to one another and at the same height level. However, the two main lines 3, 4 may be different, in particular run longitudinally with an offset or at an angle to each other and be, for example, two interconnected legs of a U-shaped path system.

Starting from the first main line 3, a full-width cutting machine 10 is mounted transversely to the longitudinal direction of the first main line 3 in a first advancing direction in the direction of the second main line 4 underground in a pre-conventionally produced start / end distance. From this position, the full-cut machine is propelled through the rock material, mining rock material and creating a first set-up or removal line 2a. Upon reaching the second start / finish section 4, the full-cut machine 10 is picked up by a transport vehicle 100 and transported on to the second main line 4 to form a second set-up or removal section 2b. Here, the full-cut machine 10 with the transport vehicle 100, which can also be referred to as a handling vehicle, turned by 180 °. If the main lines 3, 4 are dimensioned sufficiently large, the full-cutting machine 10 can be moved and turned as a compact unit.

Subsequently, by means of the full-line cutting machine 10, a second fitting or dismantling section 2 b is moved back from the second main line 4 back in the direction of the first main line 3 through the rock. The second drive direction is essentially opposite to the first drive direction, as in FIG Fig. 1 represented by the arrows. A minimum distance of the first fitting or removal path 2a to the second fitting or removal path 2b is dependent on the stability of the rock and can be several meters to several dozens Meters. Preferably, a distance between 10 to 50 meters is provided.

After reaching the first main line 3, the full-line cutting machine 10 can again be picked up by a transport vehicle 100, turned over and transported on to a third fitting or removal line 2c. The formation of a dressing or dismantling line 2 may be repeated as often as desired or necessary. Here, a ladder-like or meander-shaped route structure is created. Such an arrangement is useful in mining mining of minerals, such as diamonds.

According to Fig. 2 a further arrangement with a first main line 3 and a second main line 4 is shown, which are to be connected to each other via a fitting or removal route 2. Due to the relatively small diameter of the tube-like main sections 3, 4, a start / end section 5 is initially conventionally created in the space between the two main lines 3, 4, which can be used for assembly and disassembly of the full-cut machine 10. In the execution according to Fig. 2 is provided for the transport vehicle 100, a transport path 98 of track rails.

According to Fig. 3 a further embodiment is shown with a full-cutting machine 10 according to the invention, which is driven from a first main line 3 in a horizontal transverse direction underground through rock material. The approximately cylindrical solid cutting machine 10 having a rotary cutting head 22 forms a substantially cylindrical assembly or removal path 2. The full cutting machine 10 has an attached slave unit 70 to which the excavated rock material is transported from the cutting head 22 at the front end of the half-cut machine 10 to the rear end and is transferred by means of a conveyor 76 to a conveyor vehicle 80. The conveyor vehicle 80 is formed in the illustrated embodiment as a so-called loader with a loading bucket 82 for receiving the rock material. The follower unit 70 is connected to an exhaust pipe line 78 and other supply lines 79 to provide a corresponding supply and disposal of the full-cut machine 10.

The structure of a full-cutting machine 10 according to the invention is closer in the FIGS. 4 and 5 shown. The full-line cutting machine 10 shown has a first longitudinal module 20, a second longitudinal module 30 and a third longitudinal module 50, which are axially detachably connected to each other. The first longitudinal module 20 is designed as a cutting head 22, on whose front side a rotationally driven head plate 24 is arranged. On the front side of the top plate 24 mining tools, not shown, are arranged for the degradation of the rock material, such as rotatably mounted roller bits.

The cutting head 22 works over the entire diameter of the circular disk-shaped top plate 24 rock material, so that a cylindrical preparation or mining route 2 is driven up. The head plate 24 is rotatably supported about a longitudinal axis on a base body 26 of the cutting head 22 and via a plurality of rotary drives 28, which in Fig. 12 are shown, driven in rotation.

The first longitudinal module 20 designed as a cutting head 22 is detachably connected via connecting means, not shown, to the second longitudinal module 30, which is designed as a propulsion unit 32. The propulsion unit 32 will be described in more detail below in connection with FIGS. 6 and 7 explained.

Subsequent to the second longitudinal module, the third longitudinal module 50, which has a clamping unit 52 and an expansion unit 60, is also detachably coupled via connecting means. The tensioning unit 52 has a drum-segment-shaped bottom element 58, on which a drum-segment-shaped tensioning element 54 is adjustably mounted in the radial upward direction. The clamping element 54 can be adjusted radially outwardly by means of hydraulic clamping cylinders 56 in order to clamp and fix the full-cut machine 10 with respect to the surrounding route wall.

Rock material removed by the cutting head 22 is conveyed through the full-cut machine 10 through openings in the head plate 24 via a discharge device 16, which may have one or more screw conveyors, transport chains and / or conveyor belts to a rear area. At a rearward region of the third longitudinal module 50, an expansion unit 60 with two carriages 62 pivotable about the longitudinal axis is furthermore arranged. Along the carriages 62 each a drill drive 64 is arranged movable. Via the drill drive 64, a bar-shaped armature 63 can thus be introduced into the surrounding route wall in order to stabilize it.

The second longitudinal module 30, which is designed as a propulsion unit 32 is in the FIGS. 6 and 7 shown in more detail. The propulsion unit 32 has a drum-shaped front part 34 and a drum-shaped rear part 36. Their housing each have on the side edges facing tongue-like front projections 35 and rear projections 37. The front projections 35 and the rear projections 37 engage each other like a tooth, so that in a retracted state, the front part 34 and the rear part 36 form a substantially closed drum-shaped peripheral wall.

The front part 34 and the rear part 36 are axially movably mounted to each other and axially retractable and retractable over, for example, a total of four evenly distributed over the circumference inner feed cylinder 38. The feed cylinders 38 are each supported on radially inwardly directed support plates 42, which are simultaneously formed as a connecting means 40 for releasably connecting the adjacent longitudinal modules. For this purpose, a plurality of connecting holes 44 are introduced into the support plates 42, so that when a corresponding support plate of the adjacent longitudinal module concerns a releasable connection can be created via bolts.

The propulsion unit 32 is in Fig. 6 shown in an axially retracted state. When fixing the full-cut machine 10 relative to the route wall by means of the clamping unit 52, a feed of the cutting head 22 can be carried out. For this purpose, the feed cylinder 38 are axially extended in the propulsion unit 32, so that the cutting head 22 is pressed with a predetermined pressing force against the working face of the upcoming mountains. After reaching the maximum feed, the clamping unit 52 is released. Subsequently, by retracting the feed cylinder 38, the rear part 36 can again be retracted in the feed direction into the front part 34 of the feed unit 32. Subsequently, by re-tensioning the full-cut machine 10 by means of the clamping unit 52, a further feed step.

The post-rotor unit 70 of the full-cutting machine 10 according to the invention is shown in FIG Fig. 8 shown in more detail. On a drum-shaped base plate 71, two box-shaped supply means 74 are arranged, between which extends a belt-shaped conveyor 76 for transporting the removed rock material. Within the follower unit 70, a receiving area 77 is provided for passing the dissolved rock material. The conveyor 76 can remove the dissolved rock material from the receiving area 77 to the rear to a conveyor vehicle 80, which in Fig. 3 is shown. On an upper side of the follower unit 70, which may also be referred to as a supply unit, a suction device 72 for sucking away dust is arranged. The suction device 72 is connected to the exhaust pipe 78 according to Fig. 3 connected to dissipate dust from the preparation or mining line 2. The tracking unit 70 is releasably coupled to the preceding third longitudinal module 50 and may be considered a fourth longitudinal module. Above the bottom plate 71 anchors 63 can be stored for the expansion unit 60. Furthermore, the full-cutting machine 10 is provided with a control device known in principle, which ensures a directionally accurate driving the erection or degradation route 2.

In connection with the FIGS. 9 to 14 a transport vehicle 100 according to the invention is explained in more detail, which can be used for a method according to the invention for handling and transporting a full-line cutting machine 10 according to the invention. The transport vehicle 100 has a U-shaped chassis 102 with two parallel longitudinal legs 104, which are fixedly connected to one another via a transverse leg 106. On the outer sides of the longitudinal leg 104, a cruise ship 120 are each mounted, which is provided in the illustrated embodiment with circumferential crawlers. At the top of the transverse leg 106, a drive and control unit 118 is arranged, which comprises a power supply and a control device. The transport vehicle 100 may be wired or wirelessly remotely controlled. Alternatively, an operator station for an operator can also be provided on the drive and control unit 118.

Along the inner sides of the longitudinal legs 104 of the chassis 102 rail-like strips 112 are arranged, which together with the transverse leg 106 form a shelf 114. Due to the U-shaped configuration of the Fahrgesteiles 102, a center area remains free, whereby a receiving space 108 for a receiving frame 130 is formed. The receiving rack 130, which in Fig. 10 is received and held by the bracket 110 on the transport vehicle 100.

The receiving rack 130 according to Fig. 10 has a frame structure 131 with a part-cylindrical bent upper receiving side 132. The receiving side 132 is configured to receive and hold a drum-shaped longitudinal module of the above-described full-cut maker 10. On a bottom 134 of the receiving frame 130 lateral support strips 136 are arranged. Furthermore, lateral bearing plates 138 are arranged on the underside 134, on which extendable stamp-shaped feet 140 are arranged. The feet 140 may not shown inner adjusting cylinder between the in Fig. 10 shown extended position and a retracted retraction position are moved. The adjusting cylinders can be hydraulically actuated.

The extended position of the bolt-like feet 140 is then taken when the receiving frame 130 is placed on the ground or on a mounting plate. In this position, the transport vehicle 100 can travel with the holder 110 on the chassis 102 under the receiving frame 130. By retracting the feet 140, the support frame 130 is lowered, wherein the support strips 136 come into contact with the support surface 114 of the rail-like strips 112 of the bracket 110 on the chassis 102. The power supply of the actuating cylinder of the feet 140 can be done via the connection and control unit 118 of the transport vehicle 100 via not shown releasable supply lines. After the receiving frame 130 is placed on the holder 110 in the receiving space 108 of the transport vehicle 100, as in Fig. 11 illustrated, the receiving frame 130 can be moved by the transport vehicle 100.

The transport vehicle 100 with the receiving frame 130 can now be moved approximately to disassemble a full-cutting machine 10. After creating a first branch line 2 a through the full-cut machine 10, a first longitudinal module 20 can be accommodated by the transport vehicle 100, such as in FIG Fig. 12 is shown. The receiving frame 130 and the transport vehicle 100 are overall designed so that the first longitudinal module 20, which as a Cutting head 22 is formed with rearwardly projecting rotary actuators 28, can be accommodated in a compact manner. Due to the arrangement of the holder 110 between the two bar-like vessels 120, the height of the vessels 120 can be at least partially used as a recording room with. As a result, the overall height of the transport vehicle 100 is kept low with the recorded longitudinal module 20, so that due to the achieved compact arrangement a very good transporting and handling in the limited space conditions is made possible underground. In the illustration according to Fig. 12 the connection means 40 designed as connection holes can be seen on a rear wall of the first longitudinal module 20. The connecting means 40 correspond to the connecting means 40 on the subsequent second longitudinal module 30, which in connection with Fig. 6 were explained. The longitudinal modules can be releasably coupled to one another via appropriate bolts and screw nuts.

According to Fig. 13 It is shown that the transport vehicle 100 can also accommodate the second longitudinal module 30, which is designed as a feed unit 32. The second longitudinal module 30 is arranged on a pallet-shaped receiving frame 130, which can be designed especially for the second longitudinal module 30.

In Fig. 14 the transport vehicle 100 according to the invention with the third longitudinal module 50 is shown. The third longitudinal module 50 is likewise deposited on a receiving frame 130, which is received and held by the transport vehicle 100. The receiving frame 130 for the third longitudinal module 50 can also be designed as a universal receiving frame 130 or specifically for the shape of the third longitudinal module 50. In particular, the receiving frame 130 is designed so that the longitudinal modules can be accommodated in both longitudinal orientations.

The representation according to Fig. 14 are the arrangement of the total of four clamping cylinder 56 for adjusting the upper arcuate clamping element 54 and the hole pattern of the connecting means 40 can be seen particularly clearly.

The conversion of a full-line cutting machine 10 according to the invention can be carried out in particular by taking the individual longitudinal modules of a transport vehicle 100 with a receiving frame 130 after creating a first fitting or removal section 2a be and at an intermediate position, the receiving frame 130 with the respective longitudinal module are first discontinued. By a second transport vehicle 100 or by a corresponding maneuvering of the first transport vehicle 100, the longitudinal module can be taken up again with the receiving frame 130 from the opposite side, so that a turning and thus an assembly of the longitudinal modules is made possible with changed direction of advance. In principle, an entire unit of a full-cut machine 10 can also be accommodated by a transport vehicle 100 according to the invention, provided that this is designed with a compact overall length of a few meters.
