International Classification:
E21C 2740
US Classification:
299 32, 299 31, 299 33, 405145
Abstract:
A softwall mining method and device. Each of a plurality of mining devices comprise a supporting portion, an earth moving portion and a coupling mechanism for advancing the earth moving portion into a mining face, and for advancing the supporting portion toward the earth moving portion. Supporting portions of the devices are locked together to anchor movement of the earth moving portions, and earth moving portions of the devices are separately locked together to anchor the movement of the supporting portions.

US Patent:
5997101, Dec 7, 1999
Filed:
Feb 17, 1998
Appl. No.:
9/024438
Inventors:
Randall D. Peterson - Sandy UT
International Classification:
E21D 912, B65G 4102
US Classification:
299 64
Abstract:
A system for providing utilities and support infrastructure on a continuous basis from the surface to the cutting face of an underground operation. A flexible belt structure system incorporates water supply and discharge lines, power and communication cables, hydraulic supply and return lines, bulk lubrication delivery systems, and belt support structure for underground coal haulage. The system consists of modular components that are added at the surface and connected underground to form a continuous support structure to the working area, such that the infrastructure necessary for the mining operation is expanded or reduced to keep up with the position of the mining face without interruption of operation. The belt structure is mounted on a stationary rail fixed to the roof of the mine and is rolled forward or backwards in the belt entry as the mine advances or retreats, as applicable.

US Patent:
6086159, Jul 11, 2000
Filed:
Apr 7, 1999
Appl. No.:
9/287885
Inventors:
Randall D. Peterson - Sandy UT
Assignee:
IMC-Agrico MP, Inc. - Northbrook IL
International Classification:
E21C 2718
US Classification:
299 17
Abstract:
Slurryable ore where the overburden is unstable and subject to collapse is mined from substantially parallel elongated main trenches connected by a perpendicular trench at the bottom of the mineral seam. A plurality of softwall mining devices supported by face equipment is placed in the perpendicular trench. The devices slurry the mineral material and move into the mineral seam as the overburden sloughs behind the mining devices. The subsided overburden is supplemented as necessary with injected material. Slurried mineral flows to the parallel trenches for removal to the surface. After the softwall devices have advanced the length of the parallel trenches, the devices are withdrawn and placed in additionally developed trenches elsewhere in the ore reserve.
