An operating system, rock drilling rig and method for operating an electrically operated rock drilling rig. The operating system includes an electric system connected to an electric supply source and having one or more electric motors controlled by electric control devices. The system further includes a hydraulic system having one or more hydraulic pumps and hydraulic control devices. There are hydraulic tramming actuators connected to closed loop hydraulic circuits and hydraulic drilling actuators connected to either open or closed loop circuits.

A directional drill vice and associated methods are shown. A directional drill and associated methods are also shown. Examples of directional drill stem configurations include gripping jaws configured with a common jaw pivot. Examples of directional drill stem configurations also include a slot in a vice frame to allow lateral insertion of a drill stem segment.

The present disclosure provides a drilling machine configuration and related method that avoids drilling mud from contaminating hydraulic fluid that flows through the drive system of the machine. The disclosed system and method provides a drilling mud anti-contamination system that requires infrequent service and a system wherein the service can be quickly and easily performed.

A hydraulic collapsible rotary stand for a wireline coring underground drill rig includes two main hydraulic supporting posts, at least one hydraulic post erection cylinder, a collapsible stand base, a horizontal rotating base, and a rotary lifting cylinder, where the rotary lifting cylinder drives the collapsible stand base to move up or down; post mounting rods are hinged at a front side of the collapsible stand base; the post mounting rods are respectively connected to the main hydraulic supporting posts; a main post supporting cross-bar is provided between the main hydraulic supporting posts; through the hydraulic post erection cylinder, the main post supporting cross-bar is supported and the main hydraulic supporting post is pushed to be erected or collapsed; a hydraulic gyration supporting beam is provided between the main hydraulic supporting posts; and the hydraulic gyration supporting beam is connected to a lower sliding plate provided with a drill rig.

An apparatus includes at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to: determine a target position for a drill bit of the track-mounted drill rig; determine a turning trajectory of an aiming point of the drill bit; monitor position of the turning trajectory of the aiming point of the drill bit with respect to the target position of the drill bit during approach of the track-mounted drill rig to the target position; and cause turning of the track-mounted drill rig to align the aiming point of the drill bit with the target position of the drill bit based on determining that the turning trajectory of the aiming point of the drill bit substantially coincides with the target position of the drill bit.
