from and compiled by the Division of Statistics those used in past years.

WORK STOPPAGES 
 A total of 291 work stoppages in certain mineral industry groups during
1967 resulted in a time loss of slightly more than 4.6 million man-days of
work according to the U.S. Department of Labor, Bureau of Labor Statistics.
(See table 3.) Comparable data for 1966 were 216 work stoppages with an aggregate
time loss of slightly less than 1 million man-days. 
 Most of the large time loss in 1967 resulted from an extended major stoppage
in 
the copper mining and primary nonferrous smelting industries. This strike
period started about mid-July of 1967 and continued on into 1968. The affected
mining districts were those in the Rocky Mountain States and in Michigan,
but copper smelters were affected in most sections of the country. Some lead-zinc
mines and smelters also were affected by the same stoppage. 
 
SAFETY COMPETITIONS 
 The Bureau of Mines annually conducts safety competitions among the Nation's
mineral industries. These contests have been recognized as effective tools
to promote accident-prevention work among employees in mines, pits, and quarries.
A total of 1,308 operations participated in the contests during 1967. 
 During 1967 a total of 921 operations competed in the 43d National Safety
Competition cosponsored by the Bureau and the American Mining Congress. A
total of 422, or 46 percent, of the participants operated without a disabling
work injury during an aggregate worktime of 25.1 million man-hours, 16 percent
of the total man-hours of exposure at all enrolled plants. 
 The National Safety Competition is divided into six groups to assure equality
of competition among operations with relatively similar working conditions.
The winning operation in each group is awarded the "Sentinels of Safety"
trophy and plant flag. In addition, each employee at the winning plant receives
the Bureau's Certificate of Accomplishment in Safety in recognition of his
part in winning the record. 
 The following operations won the 1967 
"Sentinels of Safety" trophies by working the greatest number of injury-free
manhours in each of the six competing groups: 
 Stone Quarries—Millard quarry, Bethlehem Mines Corp., Annville, Pa.

 Underground Nonmetal Mines.—Barberton mine, Pittsburgh Plate Glass
Industries, Barberton, Ohio. 
 Underground Metal Mines.—No. 4 mine, Bethleh~m Mines Corp., Cornwall,
Pa. 
 Open-Pit mines (Metal and Nonmetal) 
—Sherman mine, Minnesota Ore Operations of the United States Steel
Corp., Chisholm, Minn. 
 Underground Coal Mines.—Robena No. 3 mine, United States Steel Corp.,
Frick District, Carrnichaels, Pa. 
 Surface Coal Mines.—Crescent Valley No. 7 mine, Hanna Coal Company
Division, Consolidation Coal Co., Holloway, Ohio. 
 A total of 303 operations participated in the National Sand and Gravel Safety
Competition sponsored by the Bureau. Fifty-six percent of these operations
were injury-free during 1967 and worked over 4.9 million man-hours, or 37
percent of the total man-hours of exposure of all participants.
