In certain embodiments, a mine personnel carrier includes an integrated information display and one or more processing units. The processing units may access life support data from devices associated with a life support subsystem of a mine personnel carrier. The life support subsystem provides breathable air to passengers of the mine personnel carrier, and the life support data indicates a remaining level of air available via at least a portion of the life support subsystem. The processing units access guidance data from guidance devices associated with a guidance subsystem of the mine personnel carrier. Each guidance device can detect entities within a detection range of the guidance device. The processing units initiate display in the integrated information display of at least a portion of the life support data and the guidance data. The integrated information display comprises a unified electronic display of the mine personnel carrier.

A method of supporting a substrate includes inserting a rock bolt into a hole and using the rock bolt to form a groove in a wall of the hole when the rock bolt is inserted therein. The rock bolt is caused to interact with the groove in such a way that the rock bolt is secured in the hole at least in part by the interaction.

Drilling apparatus, method, and system

A breaching apparatus includes an impactor element and a self-contained energy source. The self-contained energy source enables the impactor element to impact a first surface of a structure. The impactor element is configured to transmit a localized shock wave through the structure upon impact. The self-contained energy source is capable of accelerating the impactor element to a velocity sufficient to induce spalling at a second surface of the structure. Multiple breaching apparatuses can be supported by a frame to facilitate simultaneous or successive breaching of the structure. The breaching apparatus can be used in a method to breach a concrete structure.

A positioning, communication, and detection system designed to provide a three dimensional location of an object, navigation tools, and bidirectional surface-to-subsurface communications, and methods of using the system. The system can include one or multiple transmitters comprising electromagnetic beacons, software defined radio receivers with an associated processing unit and data acquisition system, and magnetic antennas. The system may use theoretical calculations, scale model testing, signal processing, and sensor data.
