Need solution to pull out a broken pipe dropped in the borewell

Hi, we have a borewell, 4 inches in diameter and 80 ft deep. When the mechanic was unscrewing the pipe from the joint, the pvc pipe was broken from the joint accidentally and a 1 inch pipe had dropped inside the borewell. Is there any way to pull out the pipe from the borewell ? Please mail me your suggestion or contact me on my cell no: 9439978660,
