Abstract: A method is to excavate main roadways in the upper and lower parts separately and an inclined intake roadway in the central part of the mine and pre-excavate an inclined seam roadway as the first mining face at the boundary on one side of the mine. Staring from the mine boundary, the retreating mining shall be carried out on the first mining face strip by strip with belt conveyors arranged in the upper main roadway and assistant conveying devices in the lower main roadway and inclined intake roadway; the open-off cut of the first mining face shall be built on the underside of the upper main roadway at the boundary of the mine to carry out the downward inclined mining on the strike and along the inclination.

Abstract: The present disclosure relates to a plow guide assembly for guiding a mining plow. The plow guide assembly may comprise a base member including a first guide beam for guideing the mining plow and extending along a first axis, and a second guide beam spaced apart the first guide beam for defining a service clearance therebetween, and extending along a second axis axially aligned to the first axis. The plow guide assembly may further comprise an insert element insertable into the service clearance and having a third guide beam extending along a third axis. In an assembled state of the insert element, the third axis is axially aligned to the first and second axes.

Abstract: A linkage for moving material from a first end of a conveyor toward a second end of the conveyor includes a first link and a second link. The first link includes a first side edge and a first indicator. The second link includes a second side edge and a second indicator. The second link is coupled to the first link such that the first side edge of the first link overlaps with the second side edge of the second link. Elongation of the first link in the direction of movement causes the first indicator to move relative to the second indicator, and a position of the first indicator relative to the second indicator provides an indication of a wear condition of the first link. In some aspects, a first surface and/or a second surface of one of the links includes a wear indicator representing a surface wear condition.

Abstract: The present invention refers to a set of methods and procedures that may be combined in order to greatly increase the speed of development of an access ramp in a underground hard-rock mine. More particularly, the present invention was designed to target all the bottle-necks comprised by the access operation of a hard-rock mine that employs a RAIL-VEYOR machine. The invention also comprises of an ore production line which consists in the sequential arrangement of a series of mining equipment between the work face and the entrance of a hard-rock mine. The invention also comprises a Hard Rock Mining Access Plan for a hard-rock mine which encompasses two parallel ramps interconnected by cross-cut passageways. Further, invention also comprises a Ground Support Installation method configured to shorten the time required for the installation of ground support inside of a hard-rock mine.
