SUPPLEMENTARY INFORMATION : On 
September 2, 2015 (80 FR 53070), MSHA published a proposed rule that would require underground coal mine 
operators to equip coal hauling machines and scoops with proximity detection systems. Miners working near these machines face pinning, crushing, and striking hazards that result in accidents involving life threatening injuries and death. MSHA believes that the use of proximity detection systems would reduce the potential for these pinning, crushing, or striking accidents. The comment period for the proposed rule closed on December 15, 2015. 
On January 9, 2017 (82 FR 2285), 
MSHA published a notice reopening the rulemaking record and requesting comments on issues that were raised by commenters during the comment period and on issues that developed after the record closed. The comment period was scheduled to close on February, 8 2017. 
On January 23, 2017, MSHA received 
a request to extend the comment period an additional 60 days to provide more time for interested parties to comment. In response to this request, MSHA is extending the comment period from February 8, 2017, to April 10, 2017.

Deputy Assistant Secretary for Mine Safety 
and Health Administration.
