If you haven't split your coins from the original BCH fork from BTC, you now have coins in both the ABC and SV fork. Since neither side has implemented replay protection, it may be a challenge to split the coins. Since you are a miner, you can probably mine coinbase coins from both sides and then use these as 'tainted" coins to do the split. The process looks really complicated now, especially since you haven't done the original split. In any event, if you want to claim coins at any point, you are probably going to have to import your private keys/seed phrase for your BTC to Electron Cash.(That would probably be the easiest software, AFAIK) I would move your BTC to a new private key/seed as a first step.
