A mobile tunnel boring unit is disclosed, comprising a support body driven by first drive means, the first drive means including a pair of spaced apart crawler tracks in contact with the tunnel floor and related track driving means to move the tracks. A cutter head drive means is located at an operatively front end of the boring unit, to which a rotatable cutter head can be fitted and rotatingly driven, in use, the cutter head comprising a full face cutter head fitted with cutters to bore a tunnel face. The cutter head is arranged to allow cuttings to pass through the cutter head for discharge into a muck hopper and onto a first conveyor arrangement, the cutter head drive means and a rear portion of the cutter head defining aligned central apertures to accommodate the muck hopper and a front part of the first conveyor arrangement. A telescopic shield arrangement is provided to shield the boring unit.

An autonomous roof bolter includes a material handling system having a storage pod with a plurality of spaced, fixed holders, each receiving at least one of a plurality of roof bolts. A guidance system may automatically guide the roof bolter to a location for installing a roof bolt, such as by using a manipulator for retrieving the roof bolt from the storage pod and delivering it to a drill mast. The guidance provided by the guidance system may be distance or direction. Related methods are disclosed.

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.

Some embodiments of the present disclosure provide a six-arm tunneling and anchoring machine for integrating tunneling and anchoring, which includes: a tunneling machine and a roof-bolter connected with each other. The roof-bolter includes roof bolt units, a side bolt unit, and a working platform unit. The tunneling machine includes a frame body, a walking part, a cutting partes, a revolving body, a rear support body, a loading mechanism, a conveyor, an electronic control system, a hydraulic system, a spraying system and a cooling system. There are two sets roof bolt units, which are symmetrically arranged on the left and right sides of the frame body, and are located behind a revolving center of the revolving body. Each roof bolt unit is provided with two top anchor bolts.

A drill device includes a base frame, a feed frame supported for movement relative to the base frame, and a feed device for inserting a drill element into a rock surface. The base frame includes a pair of fluid cylinders. The feed frame extends along a feed axis and includes a plurality of guide bars aligned parallel to the feed axis. The feed device is supported for movement relative to the feed frame in a direction parallel to the feed axis. The feed device includes a first guide member and a second guide member. The first guide member engages a surface of at least one of the guide bars, and the second guide member engages another surface of at least one of the guide bars.

The invention provides an umbrella-shaped anchor for rapid reinforcement of rock mass. The umbrella-shaped anchor for rapid reinforcement of the rock mass comprises an umbrella-shaped anchor head and a connecting rod. The umbrella-shaped head comprises the sliding mechanism, bearing block, guide block and main rod of anchor head. The main rod of anchor head is connected with the sliding mechanism after passing through the through-hole located in the middle of the guide block The sliding mechanism is connected with the connecting rod through the main rod of the anchor head. The multiple upper parts of bearing blocks are respectively inserted into the groove of the guide block, and they are fully fitted with the side guide rail of the sliding mechanism During installation, after the umbrella anchor head and connecting rod in the retracted state are extended into the anchor hole, the connecting rod is tensioned to drive the sliding mechanism to extrude the bearing block to open outwards and squeeze with the hole surface. The invention converts the tensile force of the anchor rod into the extrusion pressure on the rock mass, and obtains the larger anchoring force by using the higher compressive strength of the rock mass. The invention has the advantages of large applicable depth, fast construction speed, high efficiency, no grouting, large structural resistance and good stability.

A drilling and bolting rig includes a carousel rotatable about a carousel axis and including a plurality of stations configured to support a plurality of consumables, one or more actuators, and a position sensor coupled to the carousel. The one or more actuators are configured to rotate the carousel about the carousel axis. The drilling and bolting rig further includes an electronic processor coupled to the one or more actuators and the position sensor. The electronic processor is configured to detect, using the position sensor, a rotational position of the carousel, and rotate, using the one or more actuators, the carousel based on the rotational position of the carousel.

A drilling and bolting rig for performing drilling and bolting operations. The drilling and bolting rig includes a magazine for storing a consumable, a feed supporting a drill head for movement relative to a work surface, and a loader configured to retrieve the consumable from the magazine and load the consumable into the drill head. The loader includes an arm operable to engage the consumable. The arm is supported for both rotational and translational movement.

A cable feed tool includes a first support, a second support coupled to the first support, a first roller supported on the first support for rotation and configured to drive a cable, and a second roller supported on the second support for rotation and configured to drive the cable.
