218  KENTUCKY—199for each $100.~ The Cabinet determined 
the following basic valuations: In eastern Kentucky, a base value of 18 cents
per ton for unmined coal; 22 cents per ton if 
the coal is in a permitted tract; and 36 cents per ton if it is part of an
active mining operation. In western Kentucky, a base value of 8 cents per
ton; 10 cents per ton if permitted; and 16 cents per ton if part of an active
mining operation. 
The assessments were expected to be adjusted as additional information was
collected and analyzed by the Revenue Cabinet. 
 The Kentucky Geological Survey (KGS) completed a study on the use of dolomite
lime, and limestone, and for sulfur dioxide emission control in flue gas
desulfurization and fluidized-bed combustion systems.4 During the year, the
KGS published a report on low-sulfur coals in western Kentucky.5 
 An investigation of limestone deposits in southeastern Kentucky focused
on lowsilica stone suitable for use as rock dust in coal mines also was completed.
Results of this KGS study were expected to be published in 1991. 
In cooperation with the U.S. 
Geological Survey, the KGS continued work on a study of coal resources in
eastern Kentucky available for mining after environmental and technological
restrictions were considered. The U.S. Bureau of Mines joined the study to
provide mining and cost modeling expertise in an effort to determine the
amount of recoverable coal and its cost to mine, process, and reclaim. 
 The U.S. Bureau of Mines also conducted health and safety coal mine research
projects in Kentucky. A field study of three longwall pillar systems to evaluate
the effectiveness of pillar design for gate road stability was published.6
The geology of hillseams as it relates to roof instability in drift mines
in eastern Kentucky was also investigated by the Bureau. Examples of hiliseams
were described in both outcrops and coal mine roof to establish their geologic
character and contribution to roof failure.7 
 The Energy Information Administration published a State Coal Profile for
Kentucky.8 According to this report, 
more than 1 ,200 coal mines were operating in Kentucky (1988), the largest
number in any State. 
Industrial Minerals 
Lbne.—Dravo Lime Co. was the Nation's leading producer of lime.
firm operated underground limestone mines at Maysville and Carntown. Late
in the year, Dravo was negotiating a contract to supply utility grade lime
to Cincinnati Gas & Electric Co. Through the contract agreement,
was expected to provide 200,000 short tons of lime for 10 years. The lime
was expected to be manufactured at the Black River plant in Camtown. 
Sand and Gmvel (Constmction).— Construction sand and gravel production
is surveyed by the U.S. Bureau of Mines for even-numbered years only; data
for odd-numbered years are based on annual company estimates. This chapter
contains actual data for 1988 and 1990 and estimates for 1989. 
Kentucky sand and gravel statistics are compiled by geographical districts
as depicted in the State map. Table 3 presents end-use statistics for Kentucky's
four districts. 
 Output of construction sand and gravel of 8. 8 million short tons was the
highest in Kentucky since 1979, when 1 1 .7 million tons was produced. In
1990, production increased by about 
3.3 million tons compared with the 1989 total. Most of the gain was reported
from western Kentucky (district 1). Statewide, 20 sand and gravel pits were
operated in 1990; 23 operated in 1988. District 3 led the State in output,
accounting for about 60% of the State total. 
Stone (C,uthed~.—Stone production is surveyed by the U.S. Bureau
Mines for odd-numbered years only; data for even-numbered years are based
on annual company estimates. This chapter contains 
estimates for 1988 and 1990 and actual data for 1989. 
 Crushed ~ stone was the leading industrial mineral produced in Kentucky,
accounting for slightly more than one-half of the State's total value of
nonfuel mineral output. The estimated production of 50. 1 million short tons
of crushed stone in 1990 was the second highest output recorded in State
history. The alltime high total of 50.7 million tons was reported in 1988.
 In 1990, a number of independent family-owned- stone operations were sold
to major corporations. The sale of Reed Crushed Stone Co. to Vulcan Materials
Co. was completed. With that purchase, Vulcan Materials, the Nation's leading
producer of mineral aggregates, became the owner of the top-producing quarry
in the country. Rogers Group Inc. , one of the Nation's top 10 crushed stoneproducing
companies, purchased two quarries in Jefferson County. Rogers Group had operated
four quarries in Kentucky and was the State's fifth leading producer of stone
before purchasing the quarries from Billy Holloway Aggregates Co. 
 Also during the year, Kentucky's seventh leading crushed stone producer,
Lexington Quarry Co. , was purchased by a partnership of Allen Co. Inc. and
Sterling Enterprises Inc. Lexington Quarry produced limestone at an underground
mine in Jessamine County. Nally & Haydon Inc. bought Ward &
Co. ' s quarry near Lebanon, Marion County. 
 According to the Kentucky Geological Survey, wet-scrubbing systems already
installed by utilities in Kentucky require about 800,000 short tons per year
of limestone and an estimated 425,000 tons per year of lime (see Legislation
and Government Programs). 
 Small quantities of fluorspar and zinc were recovered from an open pit operation
in Crittenden County of the western Kentucky fluorspar district.
