摘要： The present disclosure relates to a method of removing a liner from a mill, the liner fastened to a mill shell by at least one liner bolt, the method including: (a) driving the at least one liner bolt through the mill shell until it becomes retained in the liner, whereby in a retained position, a head of the at least one liner bolt is exposed so as to project proud of the liner towards an interior of the mill; (b) engaging a tool onto the at least one liner bolt; and, (c) lifting the liner away from the mill shell using the tool to thereby enable the liner to be removed from the mill. A system for removing a liner from a mill and tool for use in removing a liner from a mill are also described.

摘要： A linerbolt removal tool, including: a housing; a moil supported for reciprocating movement by the housing; an inertial body located within the housing; a gas charged accumulator extending from the inertial body away from the moil; a piston moveable within the inertial body between a striking position at which the piston strikes the moil and a retracted position, whereby firing the piston from its retracted position to its striking position includes causing pressurised gas within the accumulator to accelerate the piston toward the moil, wherein the piston has a striking end for striking the moil and an opposing rear end; and a piston cap that encloses the rear end of the piston, wherein during firing, the piston and the piston cap initially accelerate together and prior to the piston reaching its striking position the piston cap separates from the piston, whereby the piston cap isolates the piston from the accumulator.

摘要： In combination a loader unit and haul unit for use in a block caving mining operation. Each of the loader unit and the haul unit comprise a removable bucket, which can be used for loading ore. In use the bucket carrying a load of ore can be transferred from the loader unit to the haul unit so that the haul unit can transport the ore from a loading site to a crusher. The loader unit and haul unit have a respective longitudinal axis extending from the fore end to the aft thereof, and the bucket is elongate with a longitudinal axis. In use when the bucket is mounted to the loader unit the longitudinal axis of the bucket is disposed orthogonally to the longitudinal axis of the loader unit. When the bucket is transferred to the haul unit, the bucket is placed upright on the haul unit with the longitudinal axis of the bucket parallel to the longitudinal axis of the haul unit.

摘要： An apparatus for suspending and guiding at least first and second linerbolt removal tools externally of a grinding mill. The first linerbolt removal tool is associated with a first carriage assembly and used for knocking out linerbolts on a cylindrical main body portion of the mill. The second linerbolt removal tool is associated with a second carriage assembly and used for knocking linerbolts on a frusto-conical end portion of the mill. Each of the first and second carriage assemblies providing no more than three degrees of freedom to their respective first and second linerbolt removal tools, and wherein at least one of the degrees of freedom is angular movement about the axis of rotation of said mill.
