A system for folding and deploying liners within tunnels includes a mobile conveyor device having a base frame including a plurality of wheels supporting a support frame. The mobile conveyor device also includes a folding assembly mounted upon the support frame at a position adjacent a first end of the base frame and a conveyor assembly mounted upon the support frame at a position adjacent a second end of the base frame.

A tunnel formwork device includes a frame and at least two support structures connectable to the frame of the tunnel formwork device and spaced apart from each other in the longitudinal direction of the tunnel formwork device for supporting the frame on a tunnel floor. The frame carries at least two hydraulic support cylinders at at least two positions spaced apart from one another in the longitudinal direction, which support cylinders can be connected to longitudinal beams running in the longitudinal direction. The longitudinal beams carry tunnel formwork elements of the tunnel formwork apparatus. At least one lifting device is arranged on the frame, which lifting device carries at least one working platform. The lifting device has a lifting drive for moving the working platform relative to the frame.

A method of installing a fill fence system at a predetermined location to at least partially cover an opening defined by a back, a floor, and side walls. The method includes providing a carrier system including a carrier assembly, locating the carrier assembly in a safe zone adjacent to the unsafe zone, and positioning an assembled fill fence assembly on the carrier assembly. The carrier assembly and the full fence assembly are moved to a preselected location. With the carrier assembly at the preselected location, the fill fence assembly is positioned at the predetermined location, and installed at least partially to cover the opening. The carrier assembly is disengaged from the fill fence assembly and removed from the preselected location. The fill fence system includes a securing element is applied to help secure the fill fence assembly in the opening.

Methods and equipment have been developed that combine the use of continuous miners, flexible conveyor trains, and longwall mining techniques to provide flexible and efficient removal of resources from subterranean formations. Some systems include: a main gate; and a tailgate connected to the maingate by an active mine face; wherein the active mine face extends at an angle between 95 and 135 relative to the maingate.
