About 2.4 billion tons of coal are available for mining in the southern Emery coalfield, Utah. This includes about 200 million tons of surface-minable coal and 2.2 billion tons of underground-minable coal. Sixty percent of the available coal identified in this study is a demonstrated resource (within 0.75 miles of a measurement location) and the remainder is less reliably identified.
This report (17 pages + a 14-page appendix) describes the coal stratigraphy, quality, and resource found in the Blackhawk Formation within four quadrangles in Sevier County, Utah ... There is a well-defined, potentially minable, 80-million-ton coal resource in the Wasatch Plateau portion of the study area, and a poorly defined, potentially minable, 690-million-ton coal resource in the Salina Canyon portion" -- Back label of container.
The petrographic database consists of 705 maceral analyses, reflectance measurements, and density and porosity determinations from Utah coal samples. These data were collected by the Utah Geological Survey from 1982 to 1995. Samples were collected from seven of Utah's 22 coal fields. Coal fields sampled are the Book Cliffs (182 samples), Wasatch Plateau (262 samples), Emery (41 samples), Sego (27 samples), Henry Mountains (173 samples), Kaiparowits Plateau (12 samples), and Coalville (four samples). The data are sorted by coal-field names; within each field the analyses are arranged alphabetically by coal-bed name to facilitate comparison. The aim of the database is to provide the industry with information on petrographic properties of Utah coals. In addition, it should help the coal operators and purchasers to determine the best uses for Utah coals.
This CD contains a 23 page report of an investigation to determine coal resources in Kane County Utah. The research methods and means of qualifying coal as commercially viable, or extractable enough to constitute a resource, are presented in conjunction with the total coal-resource estimation.
The value of Utah's mineral production in 1996 is estimated to be $2.2 billion, a decrease of $197 million from 1995. This still makes 1996 the second-highest year in total mineral value output. Contributions from each of the major industry segments are: base metals, $960 million; coal, $500 million; industrial minerals, $433 million; and precious metals, $326 million.
The value of Utah's non-petroleum mineral production in 1995 is estimated to be $2.5 billion, an increase of more than $300 million from 1994, making 1995 production an all-time high. Contributions from each of the major industry segments are: base metals, $1,198 million (48 percent of total), coal, $540 million (22 percent of total), industrial minerals, $429 million (17 percent of total), and precious metals, $310 million (13 percent of total). The growth in Utah's mineral valuation by industry segment for 1993 - 1995 is shown in figure 1. Prices rose sharply for base metals (copper, molybdenum, and magnesium) in 1995 while coal and precious metals showed slight improvement. Industrial mineral prices increased modestly for some commodities and declined for other commodities.
