Determination of an updated drilling plan

A method performed by an apparatus including a drilling simulator configured to perform simulations of movement of at least one component of a drill rig, the method comprising:

• obtaining a three-dimensional (3D) model of a drilling face;
• obtaining a 3D model including 3D geometry data of at least one component of a drill rig and a kinematic model of the drill rig, the at least one component including at least one boom and the kinematic model of the drill rig enabling modelling movement of the at least one boom;
• obtaining a drilling plan indicative of a plurality of start points and end points of a plurality of holes to be drilled on the drilling face;
• performing a simulation of the drilling plan based on the 3D model of the drilling face, the 3D model of the at last one component of the drill rig, and the kinematic model of the drill rig;
• detecting, based on the simulation, a simulated collision between the at least one component of the drill rig and the drilling face, wherein the simulated collision is associated with simulated drilling of at least one of the plurality of holes;
• and
• determining an updated drilling plan comprising an adjusted start point of the at least one of the plurality of holes, in response to detecting the simulated collision.

A computer program including instructions which, when executed by an apparatus, cause the apparatus, including a drilling simulator configured to perform simulations of movement of at least one component of a drill rig, at least to:

• obtain a three-dimensional (3D) model of a drilling face;
• obtain a 3D model comprising 3D geometry data of at least one component of a drill rig and a kinematic model of the drill rig, the at least one component comprising at least one boom and the kinematic model of the drill rig enabling modelling movement of the at least one boom;
• obtain a drilling plan indicative of a plurality of start points and end points of a plurality of holes to be drilled on the drilling face;
• perform a simulation of the drilling plan based on the 3D model of the drilling face, the 3D model of the at last one component of the drill rig, and the kinematic model of the drill rig;
• detect, based on the simulation, a simulated collision between the at least one component of the drill rig and the drilling face, wherein the simulated collision is associated with simulated drilling of at least one of the plurality of holes;
• and
• determine an updated drilling plan including an adjusted start point of the at least one of the plurality of holes, in response to detecting the simulated collision.
