{Washington,D.C.}...Relatives of three miners killed at Massey Energy's Upper Big Branch in April 2010 reminded lawmakers in Washington,D.C. Thursday that it's been more than two years and two months since 29 miners were killed in the explosion and that now is the time for action on the 2010 Robert Byrd Mine Safety Protection Act. They realize Congress is unlikely to approve the legislation this year. The National Mining Association opposes the legislation, and House Republicans have so far declined to take up similar legislation.
