Preparation plant (left) pels eoal via pipeline at ConsoPs Robinson Run Mine near Shinnston. the system that joins the fixed pipeline with the continuous mining machine. Developers see the following safety and production advantages in this new hydraulic transportation system: »· Elimination of the shuttle car, belt and rail means of hauling coal underground, which make up the largest source of mine transportation accidents. · - Elimination of the need for high-current trolley wire, thus reducing mine fire hazards and increasing fire-fighting ability with a ready source of water available at high pressure and in large volumes along the pipeline route. + Reduction of the possibility of dust explosions since all dust not airborne at · the face will be entrained in water f r o m the m i n i n g maching to the preparation plant. Reduction of problems due to mechanical abrasion and wear of electrical cables and elimination of the need to handle cables manually in ion At Robinson Run Mine - Ph^e II SURFACE PIPELINE MINE PORTAL WASH PUNT Diagram shows stapes in new slurry-pipeline system. the working face area of the mine. *· Reduction of airborne dust in working areas because no dust will be generated at transfer points which will be closed to the mine environment. + Elimination of conveyor belts and belt headings, and the necessity of diverting fresh air to the return systems, thus making fresh air available for face venilation and the improvement of dust and gas control. Development of narrow mining hardware, resulting in substantially improved roof control and a lower incidence of roof falls. These prospects for better safety and production have grown out of the blend of Consol's slurry research and operating technology with more than 40 years of pipeline experience by Conoco, officials hold. Conoco has been active in pipeline transportation since 1923 through its subsidiary, Continental Pipeline Co., which presently operates more than 9,500 miles of pipeline.
