Denial of Federal Black Lung benefits affirmed.

​The claimant worked as a coal miner for approximately nine years in underground mining. The administrative law judge denied benefits, finding the claimant had failed to establish that he suffered from a totally disabling respiratory condition. The claimant appealed. The denial of benefits was affirmed on appeal. The Benefits Review Board dismissed the claimant’s arguments that he had additional coal mine employment that would have entitled him to a presumption that his total disability was related to his coal mine employment. The BRB noted that the claimant had failed to prove a total respiratory disability and, therefore, the presumption would not apply irrespective of the number of years of coal mine employment that he proved.
