Abstract
This invention is directed to a deep bore hole drilling machine which is designed for portability so that each part of the system can be broken down into subassembly units which are of less than 4,000 pounds total weight. Thus, the entire drilling system can be transported by helicopters which are capable of carrying a total weight of 4,000 pounds.
