At least one actuator is mounted to the supporting structure and configured for additionally moving at least one of the first and second bolting units.

A boom for supporting a drilling and bolting tool includes a first portion including a first end and a second end, a longitudinal axis extending between the first end and the second end; a second portion including a proximal end and a distal end, the proximal end supported for translational movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool; an actuator for moving the second portion relative to the first portion parallel to the longitudinal axis; and a fluid passage for conveying pressurized fluid between the first end of the first portion and the drilling and bolting tool adjacent the distal end of the second portion, the fluid passage positioned within the first portion and the second portion.

A manually operated pneumatic rock drill positioner for mining shaft wall boring, said positioner comprising: an articulated boom having one end for releasable coupling to a mobile ground platform and another end opposite said one end thereof; a rigid elongated drill turret defining a main body with an exposed outer wall, an inner wall opposite said outer wall, and first side edge wall and second side edge wall opposite said first side edge wall, and first end and second end opposite said first end, a lengthwise rail member integrally mounted to said turret outer wall; a carriage slidingly engaging said rail member, said carriage for slidingly carrying a pneumatic drill head over said turret exposed outer wall for reciprocating motion thereof between said first end and second end thereof; drive means for power actuating said carriage sliding motion along said rail member; a cradle member releasably anchored to said boom another end and defining a well sized and shaped for releasable engagement by an intermediate section of said turret inner wall and said first side edge wall thereof; anchoring means for anchoring said turret to said cradle member; first coupling means for pivotally connecting said turret to said cradle member for relative pivotal movement of said turret about said cradle member along a first axis; second coupling means for pivotally connecting said turret to said cradle member for relative tilting movement of said turret about said cradle member along a second axis transverse to said first axis; all in such a way that the intersection of said first axis and second axis coincides with the center of gravity of said turret positioner and is located within said turret main body, providing a balanced load-free manual operation of the positioner.

A drilling machine includes a self-propelled motor vehicle, a front drilling member, and a rear drilling member, wherein at least one of the front or rear drilling members, has at least one drilling head suited to be oriented in any direction with respect to the advance direction of the machine, and wherein at least one of the front or rear drilling members has an integrated sliding means system suited to stabilize the member on the ground.

A drilling rig includes a base and a rotation unit for drilling a hole in a mine surface. The rotation unit is moveably coupled to the base. The drilling rig further includes a cable feed device for feeding a cable bolt into the hole created by the rotation unit. The cable feed device is moveably coupled to the base and includes a pair of wheels and a transmission. The cable bolt is received between the pair of wheels. The transmission is coupled between the rotation unit and at least one of the wheels to transmit power from the rotation unit to at least one of the wheels.

A process for supporting an anchor bolt and an anchor cable on a continuous mining working face is provided. A four-arm top anchor bolt drill carriage serves as a front carriage, a six-arm side anchor bolt and top anchor cable and top anchor cable drill carriage serves as a rear carriage, and the two carriages are arranged in a front-rear direction to work in parallel. Four anchor bolt drill machines of the four-arm top anchor bolt drill carriage face to a top plate. Two drill machines are disposed in front of the six-arm side anchor bolt and the top anchor cable drill carriage. At a distance of four meters away, another two drill machines are disposed. Two top anchor cable drill machines are disposed in a middle of the anchor bolt drill machines and face to the top plate.

A boom for supporting a drilling and bolting tool includes a first portion including a first end and a second end, a longitudinal axis extending between the first end and the second end; a second portion including a proximal end and a distal end, the proximal end supported for translational movement relative to the first portion in a direction parallel to the longitudinal axis, the distal end configured to support the drilling and bolting tool; an actuator for moving the second portion relative to the first portion parallel to the longitudinal axis; and a fluid passage for conveying pressurized fluid between the first end of the first portion and the drilling and bolting tool adjacent the distal end of the second portion, the fluid passage positioned within the first portion and the second portion.
