Abstract
Disclosed herein is a horizontal boring apparatus which is comprised of a remotely controlled drilling tool lowered from a self-contained vehicle into a previously drilled vertical shaft. The tool mills away a 360 degree band of metal casing adjacent to the desired area to be bored, and extends a hydraulic powered rotary drilling tool into the formation by extending and retracting a telescoping base while alternating stabilization of the base and bit end of the drilling tool much like an inch worm. The tool is designed to drill a 1 inch bore hole up to 150 feet in any direction, or several directions. The tool and tool housing contain instrumentation for sensing direction, inclination, density, and temperature.
