Abstract: The present invention relates to a bitumen recovery process from oil sands. The oil sands may be surface mined and transported to a treatment area or may be treated directly by means of an in situ process of oil sand deposits that are located too deep for strip mining. Specifically, the present invention involves the step of treating oil sands with a composition comprising an alkanolamine and an ethylene oxide capped glycol ether and/or propylene oxide capped glycol ether.

Abstract: A method for controlling a machine operating at a worksite is provided. The worksite includes a pit region having a crest node and a low wall. The low wall is an incline having a positive slope. The method includes identifying a location of the crest node and activating a low wall detection module at the location of the crest node as the machine moves past the crest node towards the pit region. The low wall detection module is operable within a defined low wall detection gap to detect the low wall.

Abstract: A control system of a mining machine controls a driving device that drives a traveling device of the mining machine. The control system includes an acceleration command value calculation unit that calculates an acceleration command value for accelerating the mining machine, a correction value calculation unit that calculates a correction value for the acceleration command value based on a first driving force component of the driving device to cause the mining machine to travel at a target traveling speed and a second driving force component of the driving device to offset a resistance component against traveling of the mining machine, an addition processing unit that calculates a correction acceleration command value by adding the acceleration command value and the correction value, and an acceleration command value output unit that outputs the correction acceleration command value to the driving device.

Abstract: A method for monitoring a work zone in a worksite is disclosed. The work zone includes an overburden region, a dump region having an incline of positive slope, and an initial pivot point at a junction of the overburden region and the incline. The method includes monitoring, by a controller, an elevation of the work zone based on an elevation data received from one or more sensors. Further, the method comprises detecting, by the controller, a location in the work zone having an elevation lower than an elevation of the initial pivot point based on the elevation data. Furthermore, the method comprises updating, by the controller, the detected location as a new pivot point if the detected location is within a predetermined distance from the initial pivot point.

Abstract: A rock fragmentation device and method is provided which includes a shaft and a plurality of expandable members positioned along a length thereof. The shaft has a hollow length therethrough for the passage of a pressurized fluid, and a plurality of feed apertures for delivery of the pressurized fluid to the expandable members. The shaft further includes a feed inlet for receiving the pressurized fluid from a hydraulic system. The plurality of expandable members each have an inner diameter dimensioned to receive the shaft in a tightly engaging connection, and are positioned on the shaft in fluid tight engagement effective for receiving pressurized fluid via the feed apertures without leaking fluid. The expandable members are expandable, upon filling with the pressurized fluid, to sufficient dimensions to break apart rock when fitted inside a cavity formed therein.

Abstract: Automatic change propagation in an area-based open pit mine designer is disclosed. One example includes an economic shell receiver module to receive an economic shell. In addition a user input module receives a user parametric input denoting an open pit mine shape based on the economic shell. An open pit mine designer module automatically develops an open pit mine design from the user parametric input. The user input module receives an additional area to be incorporated into the open pit mine design. The open pit mine designer module automatically propagates the additional area into the open pit mine design to generate a modified open pit mine design.

Abstract: A hierarchical control system (203) for supervising operations of an autonomous operator located within a defined geographical region containing a localized zone having an operation-defined boundary. The control system (203) has a primary controller (604) associated with the defined geographical region and a secondary controller (605) associated with the localized zone. The secondary controller (605) is responsive to the supervisory control of the primary controller (604). The autonomous operator, if located within the localized zone, is responsive to the supervisory control of the secondary controller (605).

Abstract: A method of increasing a dwell time of a slurry facility at a given ore processing location by using a mobile oil sands mining system. The method involves coordinating the operation of at least two mining conveyors to facilitate mining at least one arc-shaped sector of ore that otherwise would not be within operational reach of the slurry facility at the ore processing location. The method increases the slurry facility's operational time at the ore processing location before relocation thereof is required to keep the slurry facility within operational reach of at least one receding mine face.

Abstract: A method of mining is disclosed. The method includes mining material in a mine in accordance with a mine plan designed to maximise the financial performance of the mining operation at the mine. The mine plan is based on mining to at least produce: (i) recovery grade ore that is valuable and suitable for recovery processing and there is no net economic benefit in sorting the ore prior to recovery processing the ore; or (ii) waste material that is waste and there is no net economic benefit in sorting the material; or (iii) economically sortable ore wherein there is a net positive economic benefit in sorting the ore prior to recovery processing the ore
