  19. Main Menu Next An analysis was conducted from January 2000 – December 2004 on newly employed inexperienced coal miners. Any injured employee with a year or less total experience counted as a “new miner”. The analysis was performed using the MSHA Teradata system. This data retrieval system incorporates data from the 7000-1 forms which are completed and submitted by the mine operator.
