  • Publication number: 20110018332
    Abstract: The present disclosure provides a method for mining a material in an underground environment. The method comprises positioning a structure in an underground roadway and locating the structure so that the structure provides a reactive force when a cutting head is pushed against the material via a series of members coupled to the structure. The roadway is suitable for passage of people and transportation of machinery and removed material. The method also comprises coupling the cutting head to at least one of the members of the series of members and the series of members to the structure. Further, the method comprises forming a plurality of branch tunnel portions projecting from the roadway into the material using the cutting head and the series of members coupled to the structure, comprising repositioning the cutting head and the series of members between formation of the branch tunnel portions. At least one of the formed branch tunnel portions has a length of more than 50 m.

  • Publication number: 20100308641
    Abstract: A conveyor system for an open pit mine may include one or more conveyor lines. The conveyor lines are used to transport material from one location in the mine to another location. The material transported may be a waste material, such as overburden material, or coal. The conveyor lines may move from a first end of the pit to a distal second end. When the conveyor lines reach the second end, they may reverse direction and return towards the first end. During this reversal in direction of travel, equipment may be selectively swapped between the conveyor lines. The conveyor lines may include at least one mobile bridge conveyor. Each mobile bridge conveyor may support one or more conveyors that transport the material.

  • Publication number: 20100276983
    Abstract: This description is directed to a method and system for integrating an in-situ bitumen recovery operation with a bitumen mining operation for improved efficiencies and synergies therebetween. The method comprises obtaining a production fluid from the in-situ bitumen recovery operation, directing the production fluid to the bitumen mining operation, and incorporating the production fluid into the bitumen mining operation. The basic integrated system comprises a production well for recovering production fluid from the in-situ bitumen recovery operation, a bitumen mining and extraction facility, and a transporter for directing the production fluid from the production well to the bitumen mining and extraction facility for incorporation into the mining and extraction operation. The in-situ recovery operation may be a thermal operation, such as steam-assisted gravity drainage (SAGD), cyclic steam stimulation (CSS), or a derivative thereof.
