Coal slurry systems— a viable transport alternative

Abstract Coal is rapidly becoming a major alternative to oil. According to the World Coal Study Final Report, total world coal trade could approach one billion tons annually by the year 2000. To facilitate the increased production and export market potential of the coal producing countries, advancements must be made to improve the transportation systems. Coal slurry pipeline systems could play a significant role in achieving these market forecasts.
There are three major components to a coal slurry system— the preparation plant, the pipeline and the dewatering plant. The experience and expertise gained from the Consolidation Coal Company system in Ohio, the Black Mesa system in Arizona and ETSI's Coal Evaluation Plant demonstrate that slurry pipeline technology is proven and available to meet the coal transport challenge.
The costs of transporting coal by slurry pipeline can offer significant savings, as about 70 per cent of its costs are fixed. The reverse is true for railroads, where 75 to 80 per cent of the costs vary with inflation. All forms of transport—rail, barge and pipeline—will be required to move the massive volumes of coal. Coal slurry systems can provide a viable transport alternative.
Keywords: Slurry systems, Coal slurries, Transportation, Pipelines, ETSI system, Coal preparation, Pump stations, Dewatering plants, Black Mesa pipeline.

Summary: A study has been done of the scale-up of laboratory bench-scale flotation to continuous plant circuit performance. It was found that the impellor speed and the airflow rate influenced the results and in this case extreme values of these operating variables were required in order to reproduce the plant rougher results in the laboratory. Despite the experimental uncertainty introduced by these extreme values, it was demonstrated that the plant performance could be predicted and experimentally...

Summary: This paper will discuss strategies for the introduction of computer technology in the mine environment. More specifically, it will focus on issues such as: (a) make or buy; (b) programmerless mines; and (c) support from corporate groups. The paper relates these strategies to systems for mine operations. These will be illustrated by considering the implementation of some phases of these systems at Teck Corporation.

Summary: Recently, a number of major mining companies seemed unable to find a president from within the industry, and were searching outside the industry. From this, one could conclude that managers within the industry are either not being prepared or are not preparing themselves for presidential responsibility. Opinions were sought from a number of senior executives, to attempt to define the skills a prospective president should acquire and what actions a company could take or that a prospective...

Summary: The major features of the CANMET thermodynamic mine ventilation network program, developed by the Mining and Mineral Process Engineering Department of the University of British Columbia for the Canada Centre for Mineral and Energy Technology (CANMET), are described.
The program is designed for use by deep Canadian mines in planning ventilation flows where the effects of auto-compression of air, moisture liftwork and natural ventilation are significant. Routines to simulate stalled fans and...

Summary: Trends in world coal markets indicate that the next twenty years could be a period of intensive development for British Columbia's coal resource. This paper examines demand projections for metallurgical, thermal and chemical feedstock coals, with particular reference to domestic and Pacific Rim markets. Supply possibilities, from the point of view of British Columbia's competitive position, are explored, with emphasis on the interaction of such factors as capital, labour, port and transportat...

Summary: The paper identifies two of the main problems encountered in recent hydrometallurgical plants for the recovery of gold and silver: firstly, the plant recovery is lower than anticipated from the testwork; secondly, the metallurgical accounting figures cannot be reconciled.
The principal reasons for the plant recovery being lower than the testwork are discussed, together with solutions that can minimize these problems both during the design stage and during the plant operation after the...

Summary: Thrashing one's way through a jungle of entangled tax rules is no easy task today, as Canada's legislators continue to complicate this country's income tax laws. A t some magical point, there is presumably some balance to be struck between legislation which is equitable and unambiguous on theonehand, and at the same time is efficiently complied with and administered. It is becoming increasingly clear that the legislation is not in balance, and that there is a pressing need for some simplifica...

Summary: The Line Creek Project is located in southeastern British Columbia, approximately 25 kilometres north of Sparwood. The design is to produce a total of 2.7 million tonnes of coal annually. This is made up of 1.4 million tonnes of thermal coal and 1.3 million tonnes of metallurgical coal.
Construction commenced in the spring of 1980 and mining operations began in July 1981. The thermal processing plant, maintenance and dry facilities, as well as extensive road and bridge construction, were...
