To direct the Secretary of the Interior to issue a report regarding the effects of mine subsidence.

HR 9140 requires the Secretary of the Interior to issue a report within 180 days of enactment about how mine subsidence affects communities. The report must detail economic and welfare impacts on communities and describe current Department efforts to minimize subsidence risks. This procedural bill mandates a review of existing conditions but does not change laws or create new requirements. It directly affects communities near active or abandoned mines experiencing land sinking from underground mining.
