Definitions

  • shuttering in a mine from pit dirt with a quick setting ce- 0 A D t ment, shuttering is employed having a main frame [3 1 Fgrelgn pp a a 7 with side walls, each side wall having hydraulically op- Sept' 4403/71 erable extension plates to adjust the wall height.
  • front plate of the shuttering with its adjustable exten- [3] ⁇ LS.CCII. 61/325626: 4 25013 Sion plates, is movable between the Side plates in a 'P 4 l A rection normal to the front plate, hydraulic rams being 1 0 can: l 84 3 3 provided for this purpose.
  • the side plates are moved [56] References Cited forwardly leaving the front plate to support the pack.
  • the front plate can then be moved forward to give a further space for injecting material.
  • waste material In mining operations, particularly coal mining, a lot of waste material is produced underground which is disposed of by putting it in worked-out portions of the mine, for example by packing it alongside the gates or roadways through the worked-out portions or using it for stopping off worked-our portions.
  • the material may be mixed with a setting agent such as cement so that it will set into the form of a low quality concrete.
  • the waste material may be mixed with bentonite and water to form a flowable sludge which can be pumped to the point of utilisation before it is mixed with the setting agent. If the waste material is treated in this way, it is necessary to use shuttering to hold the waste material whilst it is setting.
  • the present invention is concerned more particularly with a form of shuttering for use in a mine in making roof supports, gateside packs and stoppings using waste material.
  • the side plates and face plate together form shuttering defining a region open at its rearward end into which pit waste and a setting agent can be injected.
  • the support structure When the material is set sufficiently, by operation of the aforementioned hydraulic ram or rams, the support structure can be moved forwardly away from the face plate thereby withdrawing the side plates forwardly along the sides of the packed material.
  • the face plate supports the front end of the pack; the side plates may extend rearwardly beyond the region last filled and thus, even when moved forwardly, can still provide support for the sides of the pack.
  • operation of the rams can be used to move the face plate forwardly between the side plates so as to form a further region within which waste material with a setting agent may be stowed.
  • injection means are provided on one or both of the side plates.
  • the injections means When the side plates are moved forwardly, the injections means will be moved for wardly past the face plate thereby enabling access to be obtained to the injection means for cleaning or maintenance when necessary without anyone having to enter the waste area.
  • the sides of the shuttering are adjustable in height to accommodate variation in the seam height of the working in which the waste material is to be packed.
  • hydraulically liftable extension plates may be mounted on side plates.
  • the side plates are preferably tapered to be of lower height at the end furthest from the face plate to allow the pack to take the roof load while still supported at its sides.
  • the face plate may be made the full height of the seam but, to accommodate variations in roof height, it may be provided with one or more hydraulically liftable extension plates.
  • the side plates may be made in sections for ease of assembly and dismantling and to enable different lengths of side plates to be used.
  • the side sections can then be withdrawn and dismantled by jacking the face plate against the end of the pack to bring the sides forwardly, removing the front sections of the sides, retracting the ram or rams to bring the support structure rack, attaching the sides thereto and repeating the operation. There is no necessity for anyone to go into the waste area.
  • the invention furthermore includes within its scope a method of disposing of pit waste in mining by packing it underground using a setting agent mixed with the pit waste wherein the pit waste and setting agent are injected into a cavity defined by a face plate and side plates, the side plates then being moved forwardly away from the face of the packed material whilst keeping the face plate in position and the face plate subsequently being moved forwardly away from the packed material whilst keeping the side plates in position to form a shuttered area into which material is injected.
  • FIG. 1 is an isometric view of a shuttering assembly forming one embodiment of the invention, the assembly being shown partly cut-away to illustrate certain details;
  • FIGS. 2 and 3 are respectively a front elevation and side elevation of a face plate employed in the assembly of FIG. 1;
  • FIG. 4 is a front elevation of the support structure of the assembly of FIG. 1;
  • FIGS. 5 to 10 are diagrammaticplan views illustrating six successive stages in the operation of the shuttering assembly of FIG. 1;
  • FIGS. 11 to 16 are diagrammatic side elevations corresponding respectively to the plan views of FIGS. 5 to 10.
  • FIGS. 1 to 4 illustrate the construction of a shuttering assembly for use in the formation of packs for disposing of pit waste underground. This particular assembly is used to form packs which extend up to the roof of the seam in the mine, the packs, when set and after the shuttering assembly is removed, forming a permanent roof support.
  • the shuttering assembly comprises a support structure having three horizontal beams 10, ll, 12 extending across the front of the assembly one above another. Extending rearwardly from the two ends of the topmost beam are side beams 13, one at each side of the assembly. Each side beam 13 is secured to two upright guide members l4, 15 attached to a side plate 16. Also attached to each side plate is a short element 17 secured to an end of the beam 11 and a lower beam 18 secured to the end of beam 12. These lower beams 18, one on each side plate, are carried on skid members 19 which rest on the floor of the seam in the mine.
  • Each side plate 16 comprises a vertical plate extending upwardly from the skid plate 19 and having a vertical height less than the minimum roof height of the region in which the shuttering assembly is to be used.
  • an extension plate 20 is movable vertically in the guides 14, 15 by means of a hydraulic ram 21 acting between the extension plate 20 and the skid member 19, the ram 21 enabling the plate 20 to be moved up to the roof of the seam so that the plates 16, 20 form a side shutter for the region into which the waste material is to be packed.
  • the front face of the shuttering is constituted by a vertical front plate 25 having a main horizontal cross beam 26 which is behind and slightly lower than beam 11.
  • beam 11 is partly cut-away to show the beam 26 which is always behind the beam 11.
  • the beam 26, at its two ends, as is most clearly seen in FIGS. 2 and 3, carries horizontal bars 27 extending through horizontal slots 28 (FIG. 1) in the side plates 16. These bars 27 are each attached to the movable element 29 of respective hydraulic rams 30 lying on the outer side of but adjacent to the side walls 16.
  • the cylinder from ram 30 is carrued on the underside of a channel section element 31 supported on the sidewall 16 and by an upright frame member 32 from the skid member 19.
  • the front plate 25 has, on its front face, guide members 33 in which are slidable vertical extension plates 34, each operable by means of a hydraulic ram 35.
  • the main front plate 25 has a height less than the minimum height in which the shutter assembly is to be operated and the extension plates 34 enable the shuttering to be extended up to the roof of the seam.
  • the assembly thus far described has a support frame including the front beams 10, 11, 12 and the side plates 16 with their extensions 20 forming one part, Movable therein by means of rams 30'is the front face assembly of FIGS. 2 and 3.
  • Injection of material into the region within the shuttering is through an inlet 36 (FIG. I).
  • pit waste is pumped through the inlet 36 into the region between the previously formed pack and face plate.
  • This pit waste is conveniently crushed or granular material mixed with sodium bentonite and water as is described in the aforementioned British Patent Application No. 29770/71.
  • a setting agent in the form of a cement or other settable material together with water is injected as a grout into the pipe leading to the inlet 36.
  • the setting agent is formed of 30 percent'gypsum and 70 percent Portland cement.
  • a cement with a water polyethylene oxide gel is employed as the setting agent. This forms a low quality cement in the region within the shuttering.
  • the front and side extension plates 34 and 20 are lowered by rams 21, 25 as illustrated in FIGS. 6 and 12.
  • the side rams 30 are then operated to move the support member and side plates 16 forwardly leaving the front plate 25 in position as shown in FIGS. 7 and 13.
  • the face plate 25 supports the front end of the pack as the side plates 16 are being moved.
  • the side plates are only moved a short distance forwardly and thus the sides of the pack remain substantially supported by the side plates over the region where material was last injected. This operation can be effected while the material is only partially set.
  • the side extensions 20 are then raised as shown in FIGS. 8 and 14.
  • the front plate 25 can then be moved forwardly as shown in FIGS. 9 and 15 and the front extension plates 34 raised, as shown in FIGS.v 10 and 16 to form a new cavity into which waste material can then be injected.
  • the method and apparatus described above may be used for disposing of waste material in mining by forming gateside packs, that is to say packing the material into worked out seams along the sides of gates (or roadways). It may also be used in other ways, for example,
  • Shuttering for use in packing waste material in a mine comprising a face plate, a support structure including a front portion extending across the front of the face plate and side portions extending at right angles to the front portion, the face plate being arranged to be moveable with respect to the support structure in a direction normal to the plane of the face plate, at least one hydraulic ram operatively connected between the support structure and face plate and arranged to effect relative movement between the face plate and the support structure in the direction normal to the plane of the face plate, and said plates carried on said side portions of said support structure and lying in parallel planes spaced apart a distance slightly greater than the width of the face plate, the face plate being located between the side plates.
  • Shuttering for use in packing waste material in a mine comprising a support structure, side plates carried on said support structure at the two sides thereof and extending rearwardly from said support structure, a face plate behind said support structure extending between the two side plates and slidably mounted thereon, hydraulic ram means operatively arranged between the support structure and face plate to effect relative movement therebetween in a direction normal to the plane of the face plate and hydraulically operable extension plates on said sise plates and face plates for adjusting the height of the shuttering.
  • a method of disposing of pit waste in mining by packing it underground using a setting agent mixed with the pit waste comprising the steps of injecting the pit waste and setting agent into a cavity defined by a face plate and side plates at right angles to the face plate and hydraulically moving the side plates forwardly away from the face of the packed material while keeping the face plate in position and subsequently hydraulically moving the face plate forwardly away from the packed material while keeping the side plates in position to form a further shuttered area into which material is injected.
