Archived Weekly / Monthly Coal Production Data |
||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Archived Weekly, revisedEIA revises its weekly estimates of State-level coal production using quarterly mine-level coal production data when they become available from the Mine Safety and Health Administration (MSHA). This method of revision guarantees that EIA’s revised weekly coal production estimates for each past quarter conform with the MSHA surveyed data. All weeks reported in the tables end on a Saturday. The estimates for the first and last weeks in a year include estimated coal production only for the days that occurred in the year. In 1994 and 2000, January 1 was a Saturday and a holiday. EIA assumed no coal was produced on those days. Therefore, for 1994 and 2000, "Week 1" started on January 2 and ran through January 8.
Units in all tables are short tons. Note: EIA uses the following equation to revise its weekly coal production estimates: Revised weekly estimate (State A) = Monthly Files, revisedEIA revises its first-round monthly estimates of State-level coal production using quarterly mine-level coal production data when they become available from the Mine Safety and Health Administration (MSHA). Revised monthly coal production estimates can be accessed from the table. State and U.S. totals in each yearly table agree with EIA's published data. The qualifications and descriptions discussed for the weekly tables also apply to the monthly tables. |
