If its in the way to a significant degree then dig a tunnel long enough that you wont render it when going about your ordinary business. Spawn an alt, give him some water, and run it down that tunnel to banish the troll until you can deal with it.
Start spamming your coordinates on chats and offer to open gates to your mine, and somebody will come kill it for sure.
