Injuries are divided into 3 categories:

FATAL (work-related injuries resulting in death to employees on active mine property);

NONFATAL, DAYS LOST (NFDL) cases (occupational injuries that result in loss of one or more days from the employee's scheduled work, or days of limited or restricted activity while at work);

NO DAYS LOST (NDL) cases (occurrences requiring only medical treatment - beyond first aid). "Incidence rates" are the number of injuries in a category times 200,000 divided by the number of employee-hours worked.

Coal data are separated into hard coal "Pennsylvania anthracite", and soft coal, "Bituminous", which also includes lignite and brown coal. "Coal production" is in short tons (2000 avoirdupois pounds) of clean coal produced, not stockpiled. Other canvasses shown are: Metal, Nonmetal, Stone, and Sand and Gravel.

Beginning in 1983, reporting requirements for contractors performing certain types of "high hazard" work (such as drilling and blasting, equipment repair) on mine property were changed and thus their data are shown separately.

"Accident Classification" categorizes the accident situation, not the resultant injury.
