A method for assigning a set of tasks to a plurality of mining machines, said machines being arranged to be driven between positions for performing tasks is provided. The method includes defining a first set of constraints to be fulfilled finding an overall solution fulfilling the first set of constraints by solving each constraint as a sub-problem, a solution to at least one sub-problem being dependent on the solution of at least one other sub-problem; the overall solution fulfilling the first set of constraints being an overall solution where a first of said sub-problems is validated by solutions of others of the sub-problems, and assigning tasks to the machines according to the determined validated overall solution, wherein tasks are arranged to be carried out at least partially overlapping in time by the mining machines.

The present disclosure provides a method for treating a high and steep landslide in a mine with a gently-inclined and weak interlayer. The method comprises the following steps as S1˜S4: S1. excavating small-benches on stable bedrock below a weak interlayer to form working surfaces for risk elimination process of landslide; S2. conducting the risk elimination process; S3. transporting a landslide accumulation body to a crushing station or a rock dump site; S4. repeating steps S1 to S3, and continuously advancing risk elimination along the working surfaces for the risk elimination process of landslide until treatment of the high and steep landslide in a mine with a gently-inclined and weak interlayer is completed. The method can treat the landslide from the root cause, avoiding a secondary landslide. The method does not affect structures and buildings in a mine, ensuring safety of personnel and excavator.

A system for mining for a material of interest occurring in a seam under a layer of overburden using a geological model map of a geological formation, the geological model map including a desired drilling end point at a predefined position relative to a geological boundary between the layer of the overburden and the seam. A drill controller is configured to control operation of a drill drilling a blast hole. A sensor pack is configured to: sense, while the blast hole is being drilled in the geological formation, parameters associated with the blast hole drilling operation; and feed the sensed parameters in real time to the drill controller. A data storage module is configured to store a geological model of the geological formation and data relating to the sensed parameters. A processor module is configured to generate a geological model map including a desired drilling end point arranged at a pre-defined position relative to the geological boundary and to locate the position of the drill bit of the drill relative to the geological boundary and to the desired drilling end point. The drill controller is configured to drill to the desired drilling end point and to cause the drill to stop drilling when the desired drilling end point has been reached.
