Mining Fee for the blocks that are orphaned
If the block he mined is no longer a part of the main chain, then his mining fee for that block would simply not exist on the chain. So the miner would not retain the fee, but it wouldn't technically be 'deducted' either. 'Deducted' implies that the system is reducing the value of the miner's account. Instead, the system just has a different UTXO set, which does not include those mining fees.
