Abstract: A method and system for applying a liner material to a contoured surface, such as an exposed rock face in an underground hard rock mine, is disclosed. Locations of a plurality of spatially distributed surface grid points on the contoured surface may be detected so as to generate a representative topographical profile of the contoured surface. Based on the plurality of surface grid points, a spray path for a liner application device configured to emit a spray of the liner material may be determined. In some cases, the spray path may have a trajectory that follows the topographical profile of the contoured surface offset therefrom within a spray range of the liner application device. Liner material may then be sprayed onto the contoured surface while controlling the liner application device to undertake at least one pass of the spray path.

Abstract: A system for offshore treatment of drill cuttings that includes a first pressurized vessel configured to receive contaminated drill cuttings and adapted to allow a compressed gas be introduced therein as the sole means for inducing movement of said contaminated drill cuttings in the first pressurized vessel, whereby at least a portion of the contaminated drill cuttings is discharged from the first pressurized vessel; and a reactor unit in fluid connection with the first pressurized vessel for separating the contaminated drill cuttings into drill cuttings and contaminants, wherein the reactor unit includes a processing chamber having at least one inlet and outlet; and a rotor mounted in the processing chamber, the rotor including a shaft; and a plurality of fixed rotor arms extending radially from the shaft is disclosed.
