year to a low of 12.3 million tons, a 700,000-ton decrease from that of 1966.
The average value of anthracite was $7.85 per ton, an increase of $0.07 over
that of 1966. Of the 
 
total production, 6.6 million tons was shipped by truck, 5.5 million tons
was shipped by rail, and 143,000 was used as colliery fuel. Underground mining
produced 3.3 million tons of which 2 million tons was mechanically loaded
by 228 conveyors and pit-car loaders (including duck-bills and other self-loading
conveyors), 119 scraper loaders, and 21 mobile
