A Study of the Rope Haulage Systems.
NTIS: PB/222-413 Available for Reference At Burau Libraries :77 pages
This investigation was conducted to determine whether the installation of rope-hauled coolie car systems were likely to improve upon the present methods of moving men, materials, and supplies in underground bituminous coal mines in the United States. The rope-hauled coolie car and related rope-hauled systems generally are not adaptable to most bituminous coal mines in the United States that have room-and-pillar operations, the report states. The rope- hauled systems can be integrated into the haulage scheme of longwall and shortwall operations, but the systems are not being applied effectively until seam pitch or roadway gradients are steep enough to limit the use of other methods of traction. Five rope-hauled monorail systems are integrated into the transport systems of three Pennsylvania anthracite mines. Accident frequency rates for the rope-hauled man and material subsidiary systems in British coal mines show them to be 28.9 and 23.9 percent higher than the frequency rates for all underground haulage in the United States during 1966 and 1967, respectively.
