Coal mine safety regulators extend comment period on new electronic surveying rules

The US Mine Safety and Health Administration extended the public comment period for a proposed rule about electronic surveying equipment in underground coal mines. This gives interested parties another 30 days to submit feedback on the new safety standards.

This is a small procedural delay, not a structural change. It means that the new rules for how coal mines use modern surveying technology will take slightly longer to finalize. The rules themselves could change how mines operate, but this extension does not.
