An articulated, modular, track-mounted, self-propelled, remote-controlled drilling apparatus is demountable into several heli-transportable components, includi ng a drilling module and a drill support module, plus separate hydraulically-driven track carriages on which they are removably mountable. The track carriages are demountably coupled in tandem by a tri-axially articulated hitch mechanism incorporating a track steering mechanism. The drilling module carries a rotary drill, a hydraulic pump operatively connected to the track drive mechanisms, and a primary motor, which selectively drives either the drill or the pump. The use of multiple demountable modules reduce s the weight of the components to be heli-transported, thus allowing the use of smaller and more economical helicopters. The combination of self-propelled, track-mounte d modules with tri-axial articulation and remote controllability enables the assembled apparatus to operate more easily over rough terrain than known seismic drills, reducing o r eliminating the need for separate means for transporting the apparatus between borehole locations.
