Definitions
- This invention relates to equipment for use in mines, more particularly to roof bolts and a method for using same.
- Roof bolts are well known in the mining industry and are extensively employed for consolidating the roof and providing anchoring points and support. Their use involves drilling a hole in the roof of the mine and inserting into the hole a resin filled cartridge.
- the resin filled cartridges are also well known and comprise a curable resin and a catalyst for the resin contained within a sausage-like skin.
- a bolt is inserted which pierces the skin and penetrates the resin.
- the bolt is usually spun to mix the resin and catalyst and, once mixed, the resin cures and sets.
- the present invention provides a solution to this problem by the use of a device to puncture the skin of the cartridge and thereby improve the contact between the resin and the wall of the bore hole.
- a method for installing a roof bolt in a mine which method comprises: (i) drilling a hole in the roof of a mine (ii) inserting a resin cartridge having a skin into the hole 5 (iii) inserting a bolt into the hole and which comprises employing in the hole a tool having one or more sharp elements and wherein the insertion of the bolt causes the tool to puncture the cartridge and prevent the skin from expanding against the wall of the hole.
- an o assembly comprising: a cartridge and attached to one end thereof a tool having a sharp element which on the application of pressure in the bore hole is capable of puncturing the skin of the cartridge and depressurising the cartridge.
- Fig la is a side view of the tool
- Fig lb is a bottom view of the tool
- Figs 2a, 2b and 2c show the attachment of the tool to the resin cartridge and the insertion of the assembly into a bore hole 0
- Figs 3a,3b, 3c and 3d show the operation of the tool and the puncturing of the resin cartridge.
- mine in the present specification is intended to include quarries, tunnels and all underground earthworks.
- roof is intended to include not only an overhead surface but also walls and all surfaces into which anchor bolts are inserted.
- a tool for use with a cartridge to puncture the cartridge comprising a base of suitable size and cross section to be inserted in a bore hole and, extending from the base one or more o sharp elements disposed so that when the tool is located in a bore hole with the base towards the bottom of the hole, the elements project towards the mouth of the hole.
- the tool of total height H comprises a top cylindrical portion 1 of outer diameter D equal to the cartridge diameter and thickness t equal to 0.5H, with a 45° chamfer of the upper face 2 to a depth of 0.25t, and a lower face 3 containing 5 eight teeth 4 equally spaced ar 45 degrees about the perimeter of 3.
- Four rectangular through slots 7 of arc width w and height h are located in portion 1 at a o distance of 0.75t from lower face 3, equally spaced 90 degrees around D.
- Each tooth tapers to a point at the free end 10 from which a flexible finger 11 of length 1 equal to 0.52D and diameter d4 equal to t/16 extends radially towards the disk centre at an angle of 15 degrees from horizontal towards lower face 3.
- the tool is injection moulded of a hard, durable plastics material such as rhinite or nylon using a multiple stage mould though other materials may be used.
- Figs 2a, 2b and 2c in use the tool is pressed onto the clip 13 of the cartridge 14 bending the fingers 11 of the tool until they clear and wedge against the underside 15 of the clip 13 thereby retaining the tool on the clip (Fig 2b) and allowing the cartridge to be inserted into the borehole 16 in the preferred orientation with the tool end leading (Fig 2c).
- the roof bolt 17 is inserted into the bore hole 16 advancing the cartridge 14 towards the top 18 of the bore hole (Fig 3a).
- the tool element contacts the end of the hole (Fig 3b) whereupon compression of the cartridge between the bolt tip 19 and the teeth 4 of the tool is begun sufficiently to puncture the ball end 20 of the cartridge (Fig 3c).
- Continued insertion of the bolt serves to implement the flat bolt tip 19 as a plunger to extrude the resin contents 21 of the cartridge from the punctured end 20 thus affording annular flow of the resin contents between the cartridge skin 22 and bore hole wall 23 as illustrated in Fig 3d.
