Mineral production value in Kentucky increased 7 percent in 1967 for a new
record. Kentucky ranked second in the United States in production of bituminous
coal, with 18 percent of the national total, and second in the production
of both ball clay and fluorspar. 
 Coal mining was dominant in the State's mineral industry and comprised 74
percent of the total value, compared with 73 percent in 1966. Leading companies,
in order of value of production, were Peabody Coal Co., Island Creek Coal
Co., and The Pittsburgh and Midway Coal Mining Co. 
 
Legislation and Government Programs. 
—The U.S. Geological Survey and the Kentucky Geological Survey continued
the cooperative program of mapping the geology of the State on 7.5-minute
quadrangles. At yearend, 280 maps involving all or parts of 297 quadrangles
had been published. The Kentucky Geological Survey, in cooperation with the
Kentucky Department of Mines and Minerals, published an oil and gas map of

  347The Mineral Industry of Kentucky 
This chapter has been prepared under a cooperative agreement between the
Bureau of Mines, U.S. Department of the Interior, and the Geological Survey
of Kentucky, for collecting information on all minerals except fuels.

mineral resources 
 Economic Indicators.—The only economic indicators not showing an increase
were total mining employment and sale of power to large industries, manufacturers,
and mines. The reduction in sale of power to large industries reflects a
decrease in the Atomic Energy Commission's operations. Bituminous coal mining
employment increased. Total private construction value, including residential
and nonresidential, increased 40 percent over 1966 levels and was 7 percent
above 1965 levels.
