Important Starting Information
* We update a majority of the information on the Mine Data Retrieval System weekly, early Friday mornings. Violation, VPID, and Dust Sampling Data, to include Quartz sampling data, is updated daily. The information provided by the Mine Data Retrieval System (MDRS) is based on data gathered from various MSHA systems. As there may be a lag time in data being entered into those systems, there will also be a lag in the reflection of that data on the MDRS.
MSHA's Mine Data Retrieval System (MDRS) is based on the history of each mine. Many mines have been owned by more than one operator during their histories. We are providing you with the "Operator History" for each of the mine searches you do. (See More...)

Mine Information/Contractor Information Search Instructions
- Please enter a valid MSHA Mine ID or Contractor ID, if you know it. This is the quickest and most concise
way to search for information. Another way to search is by name of the operator/contractor or mine name. You may enter a
portion of the name or all of it, if you know the name. The more information you provide, the more refined your results will be.
