Definitions

  • Single pass drilling apparatus use of a one-piece drill bit, method and rock bolt for single pass rock bolting.
  • Background of the invention The present invention relates to a single pass drilling apparatus, a rock bolt, use of a drill bit and a method for single pass rock bolting according to the preambles of the independent claims within the areas of reinforcement, stabilization of excavations, road banks drilling, bench drilling, tube installation or case drilling.
  • rock bolts to reinforce excavations is usually carried out in two distinct steps. Usually, a hole is drilled and the drill steel and bit extracted before the bolt is inserted into the hole and tightened or grouted.
  • Single pass rock bolting involves carrying out these two steps simultaneously, with the task of removing the drill steel to insert the bolt being eliminated.
  • the advantages of single pass bolting include minimizing the time required for bolt installation, improving safety for drilling equipment operators, when comparing with manual or semi manual bolting, and enhancing prospects for full automation of the process.
  • a further advantage is improved quality and precision of rock bolt installation, when comparing with manual or semi manual bolting.
  • the diameter of the hole is critical for rock bolt performance in the case of friction, e.g. Split set, bolts.
  • Still a further advantage with single pass bolting is that the hole cannot collapse when retracting the drill bit since the bolt is already in the hole. This leads to much better efficiency as the bolt is always installed; i.e. there will be no lost holes.
  • Prior attempts at single pass bolting have generally been targeted at innovative rock bolts, which also act as the drill steel, having a drill bit provided about an end thereof.
  • Such apparatus are used via a rotational drilling method or a rotary/percussive drilling method and are generally unsuitable for hard ground conditions.
  • Existing hard ground percussive rock bolts that do not reuse the drill bit suffer from cost problems.
  • a wide variety of roof bolts exist and one particular form is tubular (e.g. split-sets, Swellex, etc.), having a central bore formed lengthwise through the bolt. Drill bits adapted to be extracted through a casing have been complex and accordingly expensive.
  • the drilling apparatus, the rock bolt, the use of the drill bit and the method of the present invention have as one object thereof to substantially overcome the above-mentioned problems associated with the prior art, or at least provide an alternative thereto.
  • Another object of the present invention is to provide a single pass drilling apparatus for roof bolts.
  • Still another object of the present invention is to provide a tubular expansible self-drilling roof bolt.
  • Still another object of the present invention is to provide a single pass drilling apparatus for roof bolts that is less costly to use than roof bolts of the kind described above and so to make their use in the mining industry more attractive.

  • the center axis or middle line CL1 of the pilot part 14 substantially coincides with the center axis of the rock bolt during drilling, but not during retraction of the drill bit.
  • the center axis or middle line CL2 of the reamer part 19 and the axis of the drill steel 11 coincide, but are substantially spaced from the axis CL3 of the hole 22.
  • the reference to axes CL1 and CL2 shall be understood as a reference to average middle lines in the respective parts.
  • the one-piece rock drill bit 16 comprises a body 25 and cemented carbide means, i.e. chisels and/or buttons 17, 18 and 17', 18'.

  • the pilot part makes a pilot hole 22A of less diameter and length in relation to the hole 22.
  • Dimensions of importance are as follows: RP is the greatest radius of the pilot part 14 as compared to the axis CL3 of the hole.
  • RR is the greatest radius of the reamer part 19.

  • a drilling machine such as a standard drill jumbo holds the drill steel.
  • the bolt 21 is preferably automatically fed around the drill steel and positioned behind the drill bit 16 in the drilling direction F.
  • the pilot part 14 primarily will abut against the rock such that for a short while it will machine the rock surface during circular interpolation. Then the pilot part 14 will find its correct center and begins to drill centrally while the drill steel 1 simultaneously starts wobbling about the pilot part axis CL1 , see Fig. 1 B. Then the reamer part 19 gets in contact with the rock surface and begins to ream the hole made by the pilot part 14.
  • the bolt 21 After a short while, the bolt 21 reaches the hole and is forced into the hole as shown in Figs. 1C and 1H. Usually the bolt 21 is spaced axially from the drill bit 16. The split bolt 21 can assume the diameter of the hole 22 through compression. The drill bit 16 will continue to drill and ream the hole 22, while the bolt is pushed forwardly by a coupling sleeve 26 of the drilling machine, see Fig. 1D, until feed of the different parts is stopped. The depth of the hole 22 is substantially determined by the length of the bolt 21 , i.e. when a washer 23 positioned at the trailing end of the bolt reaches the rock face or entrance of the hole further feed will be stopped, see Fig. 1E. There is a rock bolt pusher on the drilling machine.
  • the bolt pusher is a coupling sleeve 26 or a dolly tool 27, see Fig. 1 L, which is driven by the drill steel.
  • the dolly tool 27 usually rotates together with the drill steel and the bolt during insertion. However, for instance the bolt may be held such that it does not rotate during insertion, e.g. in the case of a mechanical anchor bolt, to avoid unexpected shell expansion during drilling.
  • the dolly tool can torque an expansion shell rock bolt when fully inserted.
  • the dolly tool can also slide along the drill steel to allow an easier installation of mechanical shell bolts and grouted bolts.
  • Fig. 1E shows the rock bolt fully inserted, with the drill steel and drill bit fully inserted and the pusher pushing the plate to the rock face.
  • the washer is a loose conventional plate having a central hole that cooperates with a bulge 24 at the trailing end of the bolt. Then the drill bit is retracted from the pilot hole 22A, see Figs. 1F and 1 K. It is preferable that the axial space between the bolt and the drill bit is greater than the depth of the pilot hole 22A such that the leading end of the bolt does not interfere with the retraction of the drill bit.
  • the drill bit and the drill steel can be completely retracted and can be reused for repeated drilling operations. Stated another way, the method of single pass rock bolting comprises the following steps.
  • a single pass drilling apparatus 10 comprising: an elongated drill steel 11 having a leading 12 and a trailing 13 end with reference to a drilling direction F, said leading end 12 having a connection portion 15, a one-piece drill bit 16 having rock machining means 17, 18 or 17', 18', said drill bit being connectable to the drill steel 11 , - enclosing the drill steel 11 at least partially with a rock bolt 21 , said drill bit 16 and said rock bolt 21 being designed to allow the drill bit 16 to pass the rock bolt 21 during retraction of the drill bit, - drilling a hole 22 in a rock while pushing the rock bolt into said hole, -retracting said drill steel 11 and said drill bit 16 through the rock bolt 21.
  • the machine driving the apparatus 10 can be a top hammer drilling machine, a rotary machine or a down-the-hole equipment.
  • the top of the pilot could be shaped with an angle diametrically opposite to the reamer part so as to counteract said radial forces. Said forces opposed to the reamer part will help in keeping the reamer part working at its radially outermost portion, and it will also allow wear on the pilot part on the reamer side but not too much wear on its side facing away from the reamer part.
  • the side of the pilot part facing away from the reamer part can be provided with a wear pad.
