Definitions

  • This invention relates to a method and apparatus for setting an arch in an underground passage in which the arch is constituted by a plurality of components secured together, the components comprising an arch crown section and a plurality of arch sections forming in use leg supports.
  • passages formed in underground workings such as coal mines the passages or roadways as they are often called are formed by a heading machine which cuts at the head of the passage and extracts material from the face. This material is then carried away from the face and the freshly excavated roof is supported by arches which have to be set against the roof and the walls of the newly created part of the passage.
  • the face of the passage is excavated by shot firing where holes are drilled into the face and explosive is placed in these holes.
  • the explosive is then detonated bringing about a fall of material at the face end of the passage and this fall in material is first removed, usually by a mechanical excavator with manual assistance, before the arches can be set to support the newly exposed roof and sides.
  • platforms can be erected on which arch setters can stand while the arches are raised into position first against the roof of the newly exposed passage area and against the walls.
  • the arch components are secured together, struts are placed to secure the newly set arch to the adjacent arch and if necessary lagging boards or sheets are placed behind the struts. While this is taking place the personnel concerned are exposed to the risk of falls from the roof.
  • arch setting platforms carried on mining machinery does cause problems in itself, in as much as platforms may have to be stored in the passageway away from the heading face during work on the heading face, and the excavating machinery is therefore limited in its useful excavating time whilst manoeuvring of the platform takes place.
  • a method of setting an arch in an underground passage in which the arch is constituted by a plurality of components secured together, the components comprising an arch crown section and a plurality of arch sections forming in use leg supports, and comprises the steps of positioning the arch crown section on a fixture on a support platform carried by an overhead rail device, raising the platform and fixture with the arch crown section to pass readily over any equipment in the underground passage, advancing the arch crown section to a forward location in the passage, raising the arch crown section to the roof of the passage at the location and positioning it relative to a previously set arch crown section and securing it and the fixture thereto, securing the plurality of sections to provide leg support, and subsequently removing the platform from the fixture.
  • the platform is retracted from the fixture and located below the previously set arch crown section, raised to engage the fixture thereof, the fixture is then released from the previously set arch crown and withdrawn from the arch on the support platform along the rail device.
  • the fixture may then be loaded with the next arch crown section for the process to be repeated.
  • the arch crown section is preferably secured to the fixture with quick release means such as clips, and lagging sheets may also be applied to the arch crown section and transferred by the platform so as to provide a canopy over the arch section when it is positioned.
  • lagging sheet When raised the lagging sheet may trap and secure a previously positioned sheet or sheets.
  • the lagging sheets may be secured to the arch crown by suitable lagging clips and the fixture may be designed to contain struts for securing the arch crown sections. Struts may be loosely placed into recesses in the fixture so that they are correctly positioned. The fixture is raised to position the arch crown sections.
  • the plurality of arch sections forming the leg supports may conveniently be secured to the arch crown section or fixture prior to positioning the arch crown section to the roof.
  • the arch leg sections will comprise only one leg section on each side of the arch crown section and these leg sections may be folded under the arch crown section for transportation over the equipment in the passage or, if the equipment is suitably positioned, they may be loosely connected and dragged forward with the arch crown section.
  • the leg sections can be secured by suitable means such as fishplates.
  • the overhead rail device is preferably a monorail and as the arch crown sections are successively set, further sections may be added to the monorail to extend it. These further sections are set under the safety of the support given by the recently set arches, or the support for the monorail may be attached to the arch crown prior to the crown being loaded onto the fixture.
  • apparatus for use with the method thereof includes a transport device arranged to be mounted and propelled along a monorail, the transport device including a hydraulically controlled linkage mechanism carrying at one end a platform adapted to be raised and lowered in a general horizontal plane, the platform having locating holes adapted to be engaged by spigots in an arch lifting fixture carried by the fixture platform and the fixture itself having a locating recess for receiving the arch crown section and recesses for receiving struts.
  • the monorail device is to be driven by a tug element which may be either electrically or hydraulically powered.
  • Figure 1 is a side view of a machine positioned within an underground passageway showing the apparatus of the invention in the setting position.
  • Figure 2 is a plan view of the excavating machine of Figure 1 but showing schematically part of the arch setting apparatus in a withdrawn position.
  • Figure 3 is the sectional view through the passageway showing schematically the arches in a folded position and
  • Figure 4 is a similar view to Figure 3 but showing the arches lifted to position.
  • Figure 5 is a scrap view of part of the apparatus in plan view and
  • Figure 6 is a side view of the apparatus of Figure 5.
  • an underground passageway is of a general D configuration which is easily seen from Figures 3 and 4.
  • the face of the passageway (1) is indicated at (2) and this face is cut by the cutting head (3) of an excavating machine (4) mounted on self propelling crawler tracks (5).
  • Material cut by the cutting head (3) is collected at the front of the machine (4) by gathering arms (6) and transported through the machine and away from the face by a conveyor structure (7) which extends to a delivery point (31) onto a roadway conveyor (32).
  • the passage (1) as it is formed is supported against caving by rings or arches (8) which are each made up of three sections, an arch crown section (9) and two leg support sections (10) and (11). These sections are bolted together in position by the use of fishplates (12) and the sections are spaced apart and secured by struts (13) which extend between adjacent sections along the length of the passage (1).
  • a monorail (14) is suspended by hangers (15) from the arches and the monorail carries a transport device indicated generally at (16) which includes a tug unit (17) and an arch setting unit (18).
  • the arch setting unit is comprised basically of a platform (20) which is supported at the end of a linkage mechanism (21) which is able to operate to keep the platform (20) level.
  • the linkage mechanism is controlled through a hydraulic cylinder arrangement (22) which raises and lowers the platform (20).
  • a fixture (23) is located on the platform (20) by means of spigot locations (24) and the fixture (23) has a recess area (29) into which an arch crown section (9) can be located.
  • the fixture (23) is curved to the same configuration as the arch crown section (9).
  • the fixture (23) also has longitudinally extending recesses (25) into which fixing struts (13) can be located.
  • the passageway has lagging sheets (26) fixed behind the arches.
  • the lagging sheets over the crown are fixed when the crown is loaded onto the fixture.
  • the rest of the lagging sheets are fixed after the arch legs have been secured.
  • Materials are supplied to the heading along suitable rails (27) and ventilation to the heading is supplied through a ventilation duct (28).
  • the arch setting apparatus In use the arch setting apparatus is first moved along the monorail (14) to a position behind the heading machine (4) and with the fixture (23) in a lowered position an arch crown section (9) is located in the slot (29) of the fixture (23). Struts (13) are then positioned in the recesses (25). The arch section is clipped to the fixture by quick releasable clips and a lagging sheet or series of sheets (26) are laid on top of the section and located in position, possibly by clips.
  • the hydraulic system cylinder arrangement (22) is then operated and the linkage raises the platform (20) with the fixture (23) to a position where it will pass freely over the machine (4).
  • the tug (17) then propels the apparatus along the monorail (14) to a forward position where the platform (20) is located immediately in advance of the last set arch and below newly exposed roof.
  • the hydraulic means (22) is then operated further to lift, through the linkage mechanism (21), the platform (20) and the fixture (23) to the position as shown in Figure 1. In this position the arch section (9) carried on the fixture traps its own lagging sheets (26) under the forward end of the lagging sheets (26) of the previously set arch crown section.
  • the struts (13) which are loosely connected to the previous section are now secured to the arch crown section on the fixture and tightened up. This secures the new arch crown section temporarily in position while leg sections are set.
  • the platform (1) is now lowered and this leaves the fixture (23) clipped to the arch section (9) as the spigot locations (24) remove from the fixture.
  • the apparatus is withdrawn a short distance so that the platform (20) is positioned under the previously set arch and fixture.
  • the platform is then raised to engage this previously set fixture and the clips are released so that the fixture settles back onto the platform (20) with the fixture spigots engaging in the platform (20) for correct location.
  • the platform is now lowered beneath the level of the monorail and the apparatus is withdrawn by the tug (17) to a position to the rear of the machine (4) where the fixture can be reloaded.
  • the leg sections are preferably carried forward with the arch crown section so that separate transport is not necessary around the area of the machine.
  • the leg sections may be folded up over the machine under the fixture or, preferably, they can be loosely connected to the fixture or crown section when it is loaded on to the fixture and then dragged along by the fixture spanning the machine as the apparatus (16) progresses. When the crown section is in position the joints to the leg sections can then be secured correctly by fishplates.
  • link mechanism (21) need not necessarily be hydraulically operated but may be operated by any convenient form of power device such as an electrical motor.
  • the apparatus (16) may be operated by a power pack which is itself monorail mounted or alternatively floor mounted or a power take off from the heading machine.
  • a bridge unit may be situated either over the main part of the conveyor structure (7) or over the roadway conveyor (32). This will enable the heading machine to continue working while the fixture is loaded.
  • a typical position for the bridge is as indicated by the position of the fixture in Figure 2.
  • hinged extensions such as those shown dotted in Figure 3 may be secured to the fixture (23) so as to give an umbrella type of cover.
  • the extension pieces can be supported by props and are preferably hydraulically operated.
