 Nearly 15.2 million tons of coal was recovered from underground mines, 2.1
million tons more than in 1966. Average value per ton increased by $0.01
to $4.39. Production was reported in 15 counties but over half of the underground
tonnage came from Belmont and Harrison Counties. The trend toward greater
mechanization at Ohio underground mines continued as the number of continuous
mining machines increased from 59 to 66. Nearly 8.5 million tons of coal
was mined and loaded by continuous mining machines. Operators used mainly
shuttle cars and conveyors in conjunction with the continuous miners. 
 
 Coal tonnage recovered from auger mines totaled 1.6 million tons, 6 percent
below that of 1966. Average value per ton also decreased—$3.38 compared
with $3.54 the previous year. Auger-mined coal was produced in 15 counties;
Noble and Columbiana Counties were the leading areas for production. Operators
used 50 augers 
for recovering coal compared with 53 in 
1966. 
 Twenty coal cleaning and preparation plants were active, one less than in
1966. Producers cleaned 17.2 million tons of coal of which only 958,000 tons
was cleaned by pneumatic methods and the remainder was cleaned by washing.
Of the total tonnage cleaned, 67 percent was from underground mines, 32 percent
from strip mines, and the remainder was from auger mines. Over 3.9 million
tons of coal was dried after cleaning at nine preparation plants. At mines
having crushing and treatment facilities, 24.2 million tons of coal was crushed
and nearly 5 million tons treated with dust-allaying or antifreezing materials.
Production at captive mines totaled 6.3 million tons compared with 4.5 million
tons in 1966. Of the State's total coal output, 29.5 million tons were shipped
by rail or water, 13.7 million tons by truck and the rest was consumed locally.

 Preliminary employment data indicates that an average of 8,100 men worked
