Definitions

  • Extending longitudinally of the tunnel is a conveyor that removes the mined material.
  • the conveyor incorporates a pair of parallel spaced rails upon which the shearer is mounted. The shearer moves longitudinally along the rails to move the cutting drum through the coal face.
  • the chocks include a ground engaging base and a roof support, with a hydraulic ram extending between the base and roof support to urge the roof support and base apart so as to support the mine roof till the bolts are inserted and tensioned.
  • a disadvantage of the above described method of drilling and inserting the bolts is that frequently the operator of the drill rig is not protected. Still further, the drill rig is difficult to move and relocate.
  • the mine shearer including a body to be mounted on a pair of generally parallel rails for movement along the rails, a cutting drum rotatably mounted on the body for rotation about a rotational axis that is to extend generally transverse to the rails, and motor means to drive the drum about said axis and to drive the body along the rails; and a drill rig mounted on the body and operable to form passages in a rock layer surrounding the tunnel being formed by the drum.
  • said drill rig has a control console, the console being displaced laterally from the body so as to project therefrom in a direction opposite said drum.
  • said body has a plurality of wheels to engage the rails.
  • the combination further includes an articulated arm having an end extremity, and a support frame mounted on said end extremity to receive a drill bit, with the articulated arm providing for angular movement of the support frame about a plurality of pivot axes, at least one of the pivot axes being generally perpendicular relative to said rotational axis.
  • the pivot axes include at least one pivot axis that is movable in a plane generally parallel to the rotational axis.
  • the above combination further includes a conveyor to remove mined material, the conveyor being at least partly supported by the rails.
  • Figure 1 is a schematic side elevation of a mine shearer, drill rig and chock
  • a mine shearer 10 is forming a tunnel 11 having a roof 12 and floor 13.
  • the shearer 10 includes a body 14 that rotatably supports a drum 15 having cutting picks 16.
  • the drum 15 is rotated about a rotational axis 17 by a motor (not illustrated) incorporated in the body 14.
  • the drum 15 removes material (such as coal) from the mine face 32.
  • the shearer 10 is mounted on a pair of generally parallel longitudinally extending horizontal rails 18 that are transversely spaced.
  • the shearer 10 moves longitudinally of the rails 18 so as to move the drum 15 through the material being mined and thereby forming the tunnel 11.
  • the tunnel 11 being formed extends parallel to the rails 18.
  • the abovementioned bolts are inserted by a drill rig 26.
  • the drill rig 26 includes an articulated arm 27 and a drill bit 28.
  • the drill bit 28 is rotated by a motor 29, with the arm 27 being manipulable to locate the drill bit 28 in a desired location and inclination. Operation of the drill bit 28 drills passages in the roof 12 or other tunnel wall to enable a bolt to be inserted therein by the drill rig 26.
  • the drill rig 26 includes a control console 30 positioned so that it can be easily accessed by the operator 21.
  • the operator 21 is located between the base 23 and roof support 24. Accordingly, the roof bolts can be inserted with the operator 21 essentially protected by the chock 22.
  • the control console 30 is spaced laterally from the body 14 in a direction opposite the drum 15 so that the control console 30 is positioned adjacent the shield 20.
  • a thrust motor 38 Mounted on the base 36 is a thrust motor 38 that, via a power screw assembly, moves the motor 29 longitudinally of the beam 37 to cause the drill bit 28 to drill into the rock layer.
  • the end assembly 35 and end extremity of the drill bit 28 are located adjacent the rock face by operation of the cylinders 33.
  • An advantage of the above described preferred embodiment is that the drill rig 26, by being supported on the body 14, is easily moved to a desired location at which roof bolts are to be inserted by movement of the shearer 10.
  • a further advantage of the above described preferred embodiment is being able to locate the end of the drill bit 28 adjacent the rock layer by operation of the cylinders 33.
  • the arm 27 has a base 41 fixed to the body 14, with a first arm portion 42 pivotally attached to the base 41 for angular movement about a generally upright axis 43, and an axis 44 generally perpendicular to the axis 43.
  • Attached to the end extremity of the arm portion 42 is a second arm portion 45.
  • the arm portions 42 and 45 are pivotally connected for relative angular movement about an axis 46 and an axis 47 generally perpendicular to the axis 46.
  • the axis 46 is generally parallel to the axis 43.
  • Attached to the end extremity of the arm portion 45 is a mounting 50 to which the frame 40 is attached.
  • the mounting 50 is attached to the arm portion 45 for angular movement about an axis 48.
  • the axis 48 is generally parallel to the axis 43.
  • the mounting 50 is attached to the arm portion so that the frame 40 can move angularly about an axis 49 that is generally perpendicular relative to the axis 43. Hydraulic motors are used to cause the above angular movements.
  • the axes 43, 47 and 48 are generally perpendicular relative to the axis 17, while the axes 44, 46 and 49 move in planes generally parallel to the axis 17 and floor 13.

Abstract

L'invention concerne une haveuse minière combinée à une foreuse montée sur celle-ci. La foreuse comporte une console de commande (30) positionnée de manière à être facilement accessible par un opérateur (21). La foreuse comprend en outre un bras articulé (27) à l'extrémité duquel est disposé un cadre (40) qui supporte et provoque le mouvement d'un trépan (28).
