      <link>https://trid.trb.org/View/160427</link>
      <description><![CDATA[An overview is given of the automated coal-mine rail haulage in the U.S., and the safety benefits it promises. Studies have found driverless trains and automatic loading and dumping to be commercially attractive and technically feasible.  The design of automated rail haulage in underground coal mines is discussed in some detail.]]></description>

      <title>LEASING FIGHTS COAL CAR SHORTAGES</title>
      <link>https://trid.trb.org/View/154199</link>
      <description><![CDATA[This article discusses a growing trend noted among industrial and utility plants dependent on coal as their fuel source to combat rail car shortages by leasing coal cars for their own use.  Although the railroad industry has testified to the Interstate Commerce Commission (ICC) that it is capable of keeping pace with the growing use of coal, many coal officials are not so optimistic.  Examples of how two coal companies--Island Creek Coal Co. and Peabody Coal Co.--cope with car shortages are given.]]></description>

      <title>NEW PRODUCTION CAPACITY SAGS</title>
      <link>https://trid.trb.org/View/154788</link>
      <description><![CDATA[Results of a survey conducted by the editors of Keystone Coal Industry Manual about coal industry's new production capacities now in development, expansion or planning stages are presented.  It is shown that planned new production capacity through 1987 shows an 11% drop compared with last year's forecast.  One year ago, the industry anticipated the creation of some 530 million tpy of new production between 1980 and 1987.  This year's forecast by the same companies for the same time span has dwindled to about 470 million tpy of new tonnage.  Detailed statistical tables present the relevant data.]]></description>

      <title>P &amp; M USES PREWEIGH LOADOUT UNIT</title>
      <link>https://trid.trb.org/View/87212</link>
      <description><![CDATA[On Aug. 23, 1978, Pittsburg & Midway Coal Mining Co.'s McKinley mine, near Gallup, NM, became the only coal operation in the U.S. to have a certified operable preweighing system for unit-train loading.  Coal is automatically bulk preweighed in batches of about 100 tons in a special weigh hopper before it is loaded.  High accuracy of preweighing is particularly advantageous in situations where the bulk density of the coal varies from seam to seam.]]></description>

      <title>KEYSTONE PREDICTS RAPID EXPANSION</title>
      <link>https://trid.trb.org/View/87628</link>
      <description><![CDATA[An industry-wide survey by The Keystone Coal Industry Manual is discussed and accompanied by tables showing new coal mines, as well as their development and expansion through 1987.  The survey shows that new coal production from planned  mines, will total about 644 million tpy by late 1987.  Although the majority of the new mines will be underground, surface mining will account for the larger share of the production.]]></description>

      <title>GEX EXPANDS OUTPUT AT SWISHER MINE</title>
      <link>https://trid.trb.org/View/80583</link>
      <description><![CDATA[General Exploration Co. (GEX)'s expansion of its Utah coal mining operations at the Swisher Coal Co. subsidiary is described.  To satisfy present contract commitments, Swisher will build a new preparation plant and a unit-train loading facility, and will add a third mine (two are already operating) in order to produce 1.5 million tpy of coal.  The bulk of this output will consist of clean coal, helping Swisher deal with the problem of costly transportation in Southeastern Utah.]]></description>

      <title>MCKINLEY NEARS 5-MILLION TPY GOAL</title>
      <link>https://trid.trb.org/View/79280</link>
      <description><![CDATA[Pittsburg & Midway Coal Mining Co.'s McKinley mine near Gallup, N.M., is being expanded to increase annual production to 5 million by 1980.  When completed the mine will produce from four seams of coal using four Bucyrus-Erie 55-cu-yd draglines.  Previously, mining was limited to one seam worked by a 33-cu-yd shovel.  Other features include a 75,000-ton stockpile and blending facility and a 3,000-tph unit-train loadout.  Drilling, blending and pre-weighing as well as reclamation operations are discussed.]]></description>

      <title>HOW TO BUILD BETTER HAUL ROADS</title>
      <link>https://trid.trb.org/View/73283</link>
      <description><![CDATA[The author discusses the planning and the construction of haul roads, emphasizing that surface mine operators who avoid placing subbase materials under the haul-road surface in the interest of economy are often faced with more costly operation.  A variety of construction parameters that must be considered if the haul road is going to hold up under traffic planned for it are discussed.  These include subbase and surface materials, thicknesses, road-adhesion characteristics, bearing capacity of soils, and hauling widths.]]></description>

      <description><![CDATA[Paramount Minerals Corp's. coal preparation plant, expected to be in operation by the year-end is highlighted here. Designed to receive coal feed from at least three different sources, the plant will be able to load raw or washed coal on two separate rail lines or, if preferred, simultaneously to load raw coal on one track, washed coal on another track and washed coal from two silos on a third track.  Flow sheet for the fine coal preparation facilities is presented.]]></description>

      <title>POWDER RIVER BASIN DEVELOPERS AIM AT 86 MILLION TPY BY '85</title>
      <link>https://trid.trb.org/View/67614</link>
      <description><![CDATA[The outlook for developers of western coal in Wyoming's Powder River Basin is examined in the wake of a Supreme Court decision in favor of the industry.  Some companies are stepping up development activities while others are adopting a more cautious approach. The Basin's coal developers have set their sights on a production target of 86 million tpy by 1985, but this production goal will depend on new transport facilities, including both railroad and slurry pipeline projects.]]></description>

      <title>FROM MINE TO MARKET BY RAIL...THE INDISPENSABLE TRANSPORT MODE</title>
      <link>https://trid.trb.org/View/20120</link>
      <description><![CDATA[In 1973, 371 million tons of bituminous coal, nearly 63% of US production, was loaded on rail cars at the mine.  Thus if it were not for the railroads nearly two-thirds of our coal would not be mined at all.  In large measure, the coal industry simply would not exist.  It is no exaggeration to call the railroads the logistical arm of the coal industry.]]></description>

      <title>COAL MINE DEVELOPMENT SURVEY SHOWS 492.6 MILLION TONS OF NEW CAPACITY BY 1985</title>
      <link>https://trid.trb.org/View/45953</link>
      <description><![CDATA[This survey offers a new analysis of bituminous coal's current expansion plans.  Presently in development or on the drawing boards are 492.6 million tons of new coal-mining capacity additions.  Plans disclosed by 123 firms covering the years 1975 through 1985 show there are 241 mines which will, when all are in full production, have a combined capacity for 535.9 million tons.  New coal mine development and expansion are presented in tables giving a breakdown by state, mining method, number of mines as well as by years.]]></description>
