Definitions

  • the present invention relates to a method of rock drilling. More specifically the invention relates to a method where the impact device is activated only after rock contact has been achieved.
  • the present invention which is defined in the subsequent claims, aims at achieving a method of rock drilling where the forward feed of the rock drilling machine to rock contact can occur much quicker without exerting the equipment to unnecessary and harmful empty blows.
  • fig 1 schematically shows a rock drilling machine.
  • Fig 2 shows schematically a control system for the rock drilling machine.
  • the rock drilling device shown in fig 1 comprises a machine housing 3 on which a front part 11 is fastened.
  • the drilling device comprises a drill string including a set of tubes 1, which in fig 1 is represented by the drill sleeve 1 which is the rear part, and a set of rods 2, which in fig 1 is represented by an adapter 2 arranged in the machine.
  • a drill bit 31 is arranged in the front part of the drill string.
  • the drill bit 31 is rotated by means of the set of tubes which is rotated by a rotation motor 12 via a gear wheel 13 which meshes with cogs 14 on the drill sleeve 1.
  • a hammer piston 4 is movable to-and-fro in the machine housing 3 in the usual way.
  • the hammer piston transfers its energy to the adapter 2 in the set of rods. This energy is then transferred from rod to rod in the set of rods and from the set of rods to the drill bit 31.
  • a sleeve 15 and a piston 8 are slidably arranged in the machine housing 3. These transfer a force determined by the pressure in a first chamber 5 to the adapter 2. This pressure acts forward on a surface 17. This force is during drilling used to hold the rods in the set of rods together.
  • Chamber 5 is connected to an accumulator 6 which is supplied with pressure liquid from a pressure liquid source 16 via a control device 26 and a conduit 22. Piston 8 is with close fit insertable into a second chamber 7.
  • a check valve 9 is arranged between the first and second chambers and directed such that liquid flow is allowed from the first chamber 5 to the second chamber 7. Chambers 5 and 7 together form a recoil damper 21.
  • the rock drilling machine is in the usual way movable to-and-fro along a feed beam 32 by a not shown feed motor.
  • the drill tool comprises a set of tubes and a set of rods arranged therein.
  • the drill tool can of course be a drill rod of the normal kind.
  • the control system for the rock drilling method shown in fig 2 comprises a control unit 34 provided with a memory 44 for storing drilling values. To the control unit 34 are connected a sensor 35 for the pressure in the recoil damper 21, a sensor 36 for the pressure in the not shown feed motor which moves the rock drilling machine 3 along the feed beam 32, a sensor 37 for the pressure to the rotation motor 12 and a sensor for the pressure which drives the hammer piston 4 to-and-fro, the impact pressure.
  • the control unit 34 is arranged to control a number of valves, e.g.
  • valve 39 for reducing the flow through the recoil damper 21, the valve 40 which controls the flow to the feed motor, the valve 41 which controls the pressure to the feed motor, the valve 42 which controls the flow through the rotation motor and the valve 43 which controls the pressure to the impact device for controlling the to-and-fro movement of the hammer piston 4.
  • the method of rock drilling is performed in the following way with the shown rock drilling device.
  • the pressure in the recoil damper 21 is read by the sensor 35 and stored in memory 44 in the control unit 34. This is the idle damper pressure which is used as reference value.
  • the rock drilling machine 3 is fed along the feed beam 32 toward the rock 33 through opening the valves 40 for feed flow and 41 for feed pressure somewhat by the control unit 34. No other functions are activated at this time. The essential thing is however that the impact device remains inactive during this feed movement. Rotation may occur during this forward feed toward the rock. In this condition the reaching of the rock 33 by the drill bit 31 is awaited.
  • the feeding toward the rock is interrupted when the pressure in the recoil damper 21 exceeds the reference value with a predetermined amount, for instance 10 bar. Through decreasing the damper flow by valve 39 one can obtain detection of rock contact at a smaller pressure increase than otherwise. When rock contact is detected the position of the rock drilling machine along the feed beam 32 is stored in the memory 44.
