MSHA's Data Retrieval System (DRS) is based on the history of each mine. Many mines have been owned by more than one operator during their histories. We are now providing you with the "Operator History" for each of the mine searches you do. (See More...)
We update a majority of the information on the Data Retrieval System weekly, early Friday mornings. Dust Sampling Data is updated daily. The information provided by the Data Retrieval System 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 DRS.

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.
