This dataset contains information about completed conferences beginning on 1/1/2000. When citations are contested by an operator, contractor, agent or miner, a conference may be held to discuss the details of the citations to determine whether or not a particular violation will be assessed a penalty or if an alternate action will be taken. Data beginning on 1/1/2000 contains the conference number, the responsible party requesting the conference, the event number leading to the citation and the final status of the conference for all completed conferences.

Violations at a mine for a specific violator are bundled together into billing statements referred to as Assessment Cases (assess case no). Each Assessment Case may be associated to one or more docket numbers. Excluded from this dataset are discrimination dockets and agent/miner dockets.

- Inspections Data Set
The Mine Inspections dataset lists every mine inspection conducted by MSHA beginning on 1/1/2000. The data includes the name of the mine inspected, MSHA's internal inspection number (event number), the type of inspection and the start and end dates of the inspection. Event Number is the unique key for this dataset. It also includes the Mine ID associated with the inspections which can be used to relate it to the Mines Data Set.

- Mine Addresses of Record Data Set
This dataset contains mine addresses for all mines in the database except for Abandoned mines prior to 1998 from MSHA's legacy system. The address is the one entered by the mine operator at the time a Legal ID form is completed for a requested mine identification number. It is updated by MSHA district offices as required. The mine id is the unique key for this data.
