Abstract
A system is provided for automatically maintaining the drill steel on its proper path during drilling. The drill is mounted at the end of an extendable boom, the extension of which can be controlled hydraulically. The orientation of the drill steel with respect to the boom is also controlled hydraulically. The boom can be elevated by a hydraulic system to drive the drill steel into the strata above. The position of the drill is calculated by a controller by means of several sensors. The controller then controls the extension of the boom and boom angle as well as the orientation of the drill with respect to the boom in order to maintain the drill steel in the proper position throughout the drilling process.
