摘要： An apparatus is for installing support for a surface of a mine passage, such as a mine roof, using an object, such as a roof bolt. The apparatus includes a driver adapted to advance toward the surface for driving the object into the surface. A gripper includes first and second arms for gripping the object in a deployed position, such as upper and lower arms. The arms are linked such that engagement by one of the arms with the driver during advance causes the arms to retract towards each other (downwardly, for example, in the case of the upper arm, and upwardly, for example, in the case of the lower arm). Related methods are also disclosed.

摘要： An apparatus serves to grip a cable for delivery into a borehole in a surface of a mine passage in connection with an actuator, such as a drill mast having a carriage capable of being advanced and retracted along the drill mast. A pusher is formed from a pair of jaws for engaging the cable. The jaws may be biased toward a first position for engaging the cable during an advance of the carriage, and automatically movable to a second position for releasing from engagement with the cable during a retraction of the carriage. The pusher may be pivotally mounted to a carriage capable of being advanced and retracted along a drill mast, which movement may cause the jaws to self-actuate for engaging and advancing the cable during an upstroke and release therefrom during a downstroke. Related methods are also disclosed.

摘要： A system and method for installing and removing a porous plug relative to a port of metallurgic ladle includes an extendable boom rotatable about vertical axis and pivotable up and down at a first end of the boom. A mast is coupled to a second end of the boom and rotatable about multiple axes relative to the boom to position or maintain the mast in a given orientation, such as in alignment with the port of the ladle in response to rotatable or pivotable movement of the boom. The mast includes a slider mast that is translatable along the length of the mast to insert the plug or retract the plug. The mast may also include jaw grippers to secure the plug and may be configured to rotate the plug relative to the mast. The system may automatically control the position and orientation of the boom, mast, and slider mast.

摘要： An apparatus in the form of an adapter for forming a connection comprising a first part adapted for coupling with a second part by a quick-release coupling formed by a first projection of the first part having an at least partial dovetail shape and a recess of the second part having an at least partial dovetail shape. An opening in the recess is adapted for receiving the projection in an axial direction. In other embodiments, the adapter is: (1) frictionally enhanced for engaging an internal portion of the drilling element; (2) includes a radial projection elongated in an axial direction for engaging the internal portion of the one drilling element; and/or (3) has a cutter for scoring an internal portion of the one drilling element upon being inserted therein and rotated. An adapter is also disclosed for use with a drill chuck, including for creating a "twist lock" connection.

摘要： An apparatus applies mesh from a roll to a face of a mine passage. A spindle is adapted for supporting the roll of mesh. An arm supporting the spindle extends in a generally vertical direction and is adapted for rotation about an axis aligned with a direction of elongation of the mine passage such that the spindle traverses a path for applying the mesh from the roll to the face. A mast independent of the arm carries a drill head for drilling into the face of the mine passage. Related methods are also described.

摘要： A drilling apparatus including a drill is disclosed for use with a mine roof bolter. The apparatus includes a support adapted to rotate the drill about two different axes. The first axis may be a vertical axis and the second axis may be a horizontal axis. The drilling apparatus includes a mast for supporting the drill and allowing relative movement of the drill with respect to the mast. The drilling apparatus additionally includes an element for longitudinally moving the mast with respect to the support. The drilling apparatus may further include a mesh aligner for aligning the mesh with respect to the drill. A drill guide with a small footprint may also be included which is capable retracting within a housing to avoid interference with a face of the mine when positioning the drilling apparatus.

摘要： An apparatus is for installing one or more bolts in a roof of a mine, potentially in an autonomous manner. A sensor captures image data of the roof of the mine. A controller automatically controls a boom associated with a bolter to install the bolts based at least partially on the image data. A system for capturing image data of a mine is also provided, which includes at least one sensor to capture current or present image data of a portion of the mine, such as the roof, and a controller for comparing the current or present image data to previously-collected, pre-existing image data, so as to determine a location in the mine based on the comparison. Related methods are also disclosed.
