An articulated, modular, track-mounted, self-propelled, remote-controlled drilling apparatus is demountable into several heli-transportable components, including 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 reduces 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-mounted modules with tri-axial articulation and remote controllability enables the assembled apparatus to operate more easily over rough terrain than known seismic drills, reducing or eliminating the need for separate means for transporting the apparatus between borehole locations.
