A U.S. house committee has passed a bill that would bolster the finances for health care benefits for thousands of retired coal miners and their dependents. The bill would increase transfers of interest from the abandoned mine land reclamation fund to help keep solvent a fund that pays health care benefits to retired miners. A fee on coal operators finances the abandoned mine fund. Its chief purpose is to pay for the restoration of abandoned coal mine lands. Some interest on it already goes toward miners' benefits.
